+What:		security/evm
+Date:		March 2011
+Contact:	Mimi Zohar <zohar@us.ibm.com>
+Description:
+		EVM protects a file's security extended attributes(xattrs)
+		against integrity attacks. The initial method maintains an
+		HMAC-sha1 value across the extended attributes, storing the
+		value as the extended attribute 'security.evm'.
+
+		EVM depends on the Kernel Key Retention System to provide it
+		with a trusted/encrypted key for the HMAC-sha1 operation.
+		The key is loaded onto the root's keyring using keyctl.  Until
+		EVM receives notification that the key has been successfully
+		loaded onto the keyring (echo 1 > <securityfs>/evm), EVM
+		can not create or validate the 'security.evm' xattr, but
+		returns INTEGRITY_UNKNOWN.  Loading the key and signaling EVM
+		should be done as early as possible.  Normally this is done
+		in the initramfs, which has already been measured as part
+		of the trusted boot.  For more information on creating and
+		loading existing trusted/encrypted keys, refer to:
+		Documentation/keys-trusted-encrypted.txt.  (A sample dracut
+		patch, which loads the trusted/encrypted key and enables
+		EVM, is available from http://linux-ima.sourceforge.net/#EVM.)

+Date:		January 2007
+KernelVersion:	2.6.21
+Contact:	Alan Stern <stern@rowland.harvard.edu>
+Description:
+		PCI-based EHCI USB controllers (i.e., high-speed USB-2.0
+		controllers) are often implemented along with a set of
+		"companion" full/low-speed USB-1.1 controllers.  When a
+		high-speed device is plugged in, the connection is routed
+		to the EHCI controller; when a full- or low-speed device
+		is plugged in, the connection is routed to the companion
+		controller.
+
+		Sometimes you want to force a high-speed device to connect
+		at full speed, which can be accomplished by forcing the
+		connection to be routed to the companion controller.
+		That's what this file does.  Writing a port number to the
+		file causes connections on that port to be routed to the
+		companion controller, and writing the negative of a port
+		number returns the port to normal operation.
+
+		For example: To force the high-speed device attached to
+		port 4 on bus 2 to run at full speed:
+
+			echo 4 >/sys/bus/usb/devices/usb2/../companion
+
+		To return the port to high-speed operation:
+
+			echo -4 >/sys/bus/usb/devices/usb2/../companion
+
+		Reading the file gives the list of ports currently forced
+		to the companion controller.
+
+		Note: Some EHCI controllers do not have companions; they
+		may contain an internal "transaction translator" or they
+		may be attached directly to a "rate-matching hub".  This
+		mechanism will not work with such controllers.  Also, it
+		cannot be used to force a port on a high-speed hub to
+		connect at full speed.
+
+		Note: When this file was first added, it appeared in a
+		different sysfs directory.  The location given above is
+		correct for 2.6.35 (and probably several earlier kernel
+		versions as well).

+Lockdep-RCU was added to the Linux kernel in early 2010

+Line 2776 of block/cfq-iosched.c in v3.0-rc5 is as follows:

+
+This form says that it must be in a plain vanilla RCU read-side critical
+section, but the "other info" list above shows that this is not the
+case.  Instead, we hold three locks, one of which might be RCU related.
+And maybe that lock really does protect this reference.  If so, the fix
+is to inform RCU, perhaps by changing __cfq_exit_single_io_context() to
+take the struct request_queue "q" from cfq_exit_queue() as an argument,
+which would permit us to invoke rcu_dereference_protected as follows:
+
+	if (rcu_dereference_protected(ioc->ioc_data,
+				      lockdep_is_held(&q->queue_lock)) == cic) {
+
+With this change, there would be no lockdep-RCU splat emitted if this
+code was invoked either from within an RCU read-side critical section
+or with the ->queue_lock held.  In particular, this would have suppressed
+the above lockdep-RCU splat because ->queue_lock is held (see #2 in the
+list above).
+
+On the other hand, perhaps we really do need an RCU read-side critical
+section.  In this case, the critical section must span the use of the
+return value from rcu_dereference(), or at least until there is some
+reference count incremented or some such.  One way to handle this is to
+add rcu_read_lock() and rcu_read_unlock() as follows:
+
+	rcu_read_lock();
+	if (rcu_dereference(ioc->ioc_data) == cic) {
+		spin_lock(&ioc->lock);
+		rcu_assign_pointer(ioc->ioc_data, NULL);
+		spin_unlock(&ioc->lock);
+	}
+	rcu_read_unlock();
+
+With this change, the rcu_dereference() is always within an RCU
+read-side critical section, which again would have suppressed the
+above lockdep-RCU splat.
+
+But in this particular case, we don't actually deference the pointer
+returned from rcu_dereference().  Instead, that pointer is just compared
+to the cic pointer, which means that the rcu_dereference() can be replaced
+by rcu_access_pointer() as follows:
+
+	if (rcu_access_pointer(ioc->ioc_data) == cic) {
+
+Because it is legal to invoke rcu_access_pointer() without protection,
+this change would also suppress the above lockdep-RCU splat.

+
+CFQ IO scheduler Idling Theory
+===============================
+Idling on a queue is primarily about waiting for the next request to come
+on same queue after completion of a request. In this process CFQ will not
+dispatch requests from other cfq queues even if requests are pending there.
+
+The rationale behind idling is that it can cut down on number of seeks
+on rotational media. For example, if a process is doing dependent
+sequential reads (next read will come on only after completion of previous
+one), then not dispatching request from other queue should help as we
+did not move the disk head and kept on dispatching sequential IO from
+one queue.
+
+CFQ has following service trees and various queues are put on these trees.
+
+	sync-idle	sync-noidle	async
+
+All cfq queues doing synchronous sequential IO go on to sync-idle tree.
+On this tree we idle on each queue individually.
+
+All synchronous non-sequential queues go on sync-noidle tree. Also any
+request which are marked with REQ_NOIDLE go on this service tree. On this
+tree we do not idle on individual queues instead idle on the whole group
+of queues or the tree. So if there are 4 queues waiting for IO to dispatch
+we will idle only once last queue has dispatched the IO and there is
+no more IO on this service tree.
+
+All async writes go on async service tree. There is no idling on async
+queues.
+
+CFQ has some optimizations for SSDs and if it detects a non-rotational
+media which can support higher queue depth (multiple requests at in
+flight at a time), then it cuts down on idling of individual queues and
+all the queues move to sync-noidle tree and only tree idle remains. This
+tree idling provides isolation with buffered write queues on async tree.
+
+FAQ
+===
+Q1. Why to idle at all on queues marked with REQ_NOIDLE.
+
+A1. We only do tree idle (all queues on sync-noidle tree) on queues marked
+    with REQ_NOIDLE. This helps in providing isolation with all the sync-idle
+    queues. Otherwise in presence of many sequential readers, other
+    synchronous IO might not get fair share of disk.
+
+    For example, if there are 10 sequential readers doing IO and they get
+    100ms each. If a REQ_NOIDLE request comes in, it will be scheduled
+    roughly after 1 second. If after completion of REQ_NOIDLE request we
+    do not idle, and after a couple of milli seconds a another REQ_NOIDLE
+    request comes in, again it will be scheduled after 1second. Repeat it
+    and notice how a workload can lose its disk share and suffer due to
+    multiple sequential readers.
+
+    fsync can generate dependent IO where bunch of data is written in the
+    context of fsync, and later some journaling data is written. Journaling
+    data comes in only after fsync has finished its IO (atleast for ext4
+    that seemed to be the case). Now if one decides not to idle on fsync
+    thread due to REQ_NOIDLE, then next journaling write will not get
+    scheduled for another second. A process doing small fsync, will suffer
+    badly in presence of multiple sequential readers.
+
+    Hence doing tree idling on threads using REQ_NOIDLE flag on requests
+    provides isolation from multiple sequential readers and at the same
+    time we do not idle on individual threads.
+
+Q2. When to specify REQ_NOIDLE
+A2. I would think whenever one is doing synchronous write and not expecting
+    more writes to be dispatched from same context soon, should be able
+    to specify REQ_NOIDLE on writes and that probably should work well for
+    most of the cases.

+* ARM L2 Cache Controller
+
+ARM cores often have a separate level 2 cache controller. There are various
+implementations of the L2 cache controller with compatible programming models.
+The ARM L2 cache representation in the device tree should be done as follows:
+
+Required properties:
+
+- compatible : should be one of:
+	"arm,pl310-cache"
+	"arm,l220-cache"
+	"arm,l210-cache"
+- cache-unified : Specifies the cache is a unified cache.
+- cache-level : Should be set to 2 for a level 2 cache.
+- reg : Physical base address and size of cache controller's memory mapped
+  registers.
+
+Optional properties:
+
+- arm,data-latency : Cycles of latency for Data RAM accesses. Specifies 3 cells of
+  read, write and setup latencies. Minimum valid values are 1. Controllers
+  without setup latency control should use a value of 0.
+- arm,tag-latency : Cycles of latency for Tag RAM accesses. Specifies 3 cells of
+  read, write and setup latencies. Controllers without setup latency control
+  should use 0. Controllers without separate read and write Tag RAM latency
+  values should only use the first cell.
+- arm,dirty-latency : Cycles of latency for Dirty RAMs. This is a single cell.
+- arm,filter-ranges : <start length> Starting address and length of window to
+  filter. Addresses in the filter window are directed to the M1 port. Other
+  addresses will go to the M0 port.
+- interrupts : 1 combined interrupt.
+
+Example:
+
+L2: cache-controller {
+        compatible = "arm,pl310-cache";
+        reg = <0xfff12000 0x1000>;

+Flexcan CAN contoller on Freescale's ARM and PowerPC system-on-a-chip (SOC).
 
-fsl,flexcan-v1.0 nodes
------------------------
-In addition to the required compatible-, reg- and interrupt-properties, you can
-also specify which clock source shall be used for the controller.
+Required properties:
 
-CPI Clock- Can Protocol Interface Clock
-	This CLK_SRC bit of CTRL(control register) selects the clock source to
-	the CAN Protocol Interface(CPI) to be either the peripheral clock
-	(driven by the PLL) or the crystal oscillator clock. The selected clock
-	is the one fed to the prescaler to generate the Serial Clock (Sclock).
-	The PRESDIV field of CTRL(control register) controls a prescaler that
-	generates the Serial Clock (Sclock), whose period defines the
-	time quantum used to compose the CAN waveform.
+- compatible : Should be "fsl,<processor>-flexcan"
 
-Can Engine Clock Source
-	There are two sources for CAN clock
-	- Platform Clock  It represents the bus clock
-	- Oscillator Clock
+  An implementation should also claim any of the following compatibles
+  that it is fully backwards compatible with:
 
-	Peripheral Clock (PLL)
-	--------------
-		     |
-		    ---------		      -------------
-		    |       |CPI Clock	      | Prescaler |       Sclock
-		    |       |---------------->| (1.. 256) |------------>

-                     |  |
-	--------------  ---------------------CLK_SRC
-	Oscillator Clock
+  - fsl,p1010-flexcan
 
-- fsl,flexcan-clock-source : CAN Engine Clock Source.This property selects
-			     the peripheral clock. PLL clock is fed to the
-			     prescaler to generate the Serial Clock (Sclock).
-			     Valid values are "oscillator" and "platform"
-			     "oscillator": CAN engine clock source is oscillator clock.
-			     "platform" The CAN engine clock source is the bus clock
-		             (platform clock).
+- reg : Offset and length of the register set for this device
+- interrupts : Interrupt tuple for this device
+- clock-frequency : The oscillator frequency driving the flexcan device
 
-- fsl,flexcan-clock-divider : for the reference and system clock, an additional
-			      clock divider can be specified.
-- clock-frequency: frequency required to calculate the bitrate for FlexCAN.
+Example:
 
-Note:
-	- v1.0 of flexcan-v1.0 represent the IP block version for P1010 SOC.
-	- P1010 does not have oscillator as the Clock Source.So the default
-	  Clock Source is platform clock.
-Examples:
-
-	can0@1c000 {

+Attributes of devices can be exported by a device driver through sysfs.
 
 Please see Documentation/filesystems/sysfs.txt for more information
 on how sysfs works.
 
+As explained in Documentation/kobject.txt, device attributes must be be
+created before the KOBJ_ADD uevent is generated. The only way to realize
+that is by defining an attribute group.

 Attributes are declared using a macro called DEVICE_ATTR:
 
 #define DEVICE_ATTR(name,mode,show,store)
 
 Example:
 
-DEVICE_ATTR(power,0644,show_power,store_power);
+static DEVICE_ATTR(type, 0444, show_type, NULL);
+static DEVICE_ATTR(power, 0644, show_power, store_power);
 
-This declares a structure of type struct device_attribute named
-'dev_attr_power'. This can then be added and removed to the device's
-directory using:
+This declares two structures of type struct device_attribute with respective
+names 'dev_attr_type' and 'dev_attr_power'. These two attributes can be
+organized as follows into a group:
 
-int device_create_file(struct device *device, struct device_attribute * entry);
-void device_remove_file(struct device * dev, struct device_attribute * attr);
+static struct attribute *dev_attrs[] = {
+	&dev_attr_type.attr,
+	&dev_attr_power.attr,
+	NULL,
+};
 
-Example:
+static struct attribute_group dev_attr_group = {
+	.attrs = dev_attrs,
+};
+
+static const struct attribute_group *dev_attr_groups[] = {
+	&dev_attr_group,
+	NULL,
+};
+
+This array of groups can then be associated with a device by setting the
+group pointer in struct device before device_register() is invoked:
 
-device_create_file(dev,&dev_attr_power);
-device_remove_file(dev,&dev_attr_power);
+      dev->groups = dev_attr_groups;
+      device_register(dev);
 
-The file name will be 'power' with a mode of 0644 (-rw-r--r--).
+The device_register() function will use the 'groups' pointer to create the
+device attributes and the device_unregister() function will use this pointer
+to remove the device attributes.

+  Prefix: 'exynos4-tmu'
+  Datasheet: Not publicly available
+
+Authors: Donggeun Kim <dg77.kim@samsung.com>
+
+Description
+-----------
+
+This driver allows to read temperature inside SAMSUNG EXYNOS4 series of SoC.
+
+The chip only exposes the measured 8-bit temperature code value
+through a register.
+Temperature can be taken from the temperature code.
+There are three equations converting from temperature to temperature code.
+
+The three equations are:
+  1. Two point trimming
+	Tc = (T - 25) * (TI2 - TI1) / (85 - 25) + TI1
+
+  2. One point trimming
+	Tc = T + TI1 - 25
+
+  3. No trimming
+	Tc = T + 50
+
+  Tc: Temperature code, T: Temperature,
+  TI1: Trimming info for 25 degree Celsius (stored at TRIMINFO register)
+       Temperature code measured at 25 degree Celsius which is unchanged
+  TI2: Trimming info for 85 degree Celsius (stored at TRIMINFO register)
+       Temperature code measured at 85 degree Celsius which is unchanged
+
+TMU(Thermal Management Unit) in EXYNOS4 generates interrupt
+when temperature exceeds pre-defined levels.
+The maximum number of configurable threshold is four.
+The threshold levels are defined as follows:
+  Level_0: current temperature > trigger_level_0 + threshold
+  Level_1: current temperature > trigger_level_1 + threshold
+  Level_2: current temperature > trigger_level_2 + threshold
+  Level_3: current temperature > trigger_level_3 + threshold
+
+  The threshold and each trigger_level are set
+  through the corresponding registers.
+
+When an interrupt occurs, this driver notify user space of
+one of four threshold levels for the interrupt
+through kobject_uevent_env and sysfs_notify functions.
+Although an interrupt condition for level_0 can be set,
+it is not notified to user space through sysfs_notify function.

+PMBus core driver and internal API
+==================================
+
+Introduction
+============
+
+[from pmbus.org] The Power Management Bus (PMBus) is an open standard
+power-management protocol with a fully defined command language that facilitates
+communication with power converters and other devices in a power system. The
+protocol is implemented over the industry-standard SMBus serial interface and
+enables programming, control, and real-time monitoring of compliant power
+conversion products. This flexible and highly versatile standard allows for
+communication between devices based on both analog and digital technologies, and
+provides true interoperability which will reduce design complexity and shorten
+time to market for power system designers. Pioneered by leading power supply and
+semiconductor companies, this open power system standard is maintained and
+promoted by the PMBus Implementers Forum (PMBus-IF), comprising 30+ adopters
+with the objective to provide support to, and facilitate adoption among, users.
+
+Unfortunately, while PMBus commands are standardized, there are no mandatory
+commands, and manufacturers can add as many non-standard commands as they like.
+Also, different PMBUs devices act differently if non-supported commands are
+executed. Some devices return an error, some devices return 0xff or 0xffff and
+set a status error flag, and some devices may simply hang up.
+
+Despite all those difficulties, a generic PMBus device driver is still useful
+and supported since kernel version 2.6.39. However, it was necessary to support
+device specific extensions in addition to the core PMBus driver, since it is
+simply unknown what new device specific functionality PMBus device developers
+come up with next.
+
+To make device specific extensions as scalable as possible, and to avoid having
+to modify the core PMBus driver repeatedly for new devices, the PMBus driver was
+split into core, generic, and device specific code. The core code (in
+pmbus_core.c) provides generic functionality. The generic code (in pmbus.c)
+provides support for generic PMBus devices. Device specific code is responsible
+for device specific initialization and, if needed, maps device specific
+functionality into generic functionality. This is to some degree comparable
+to PCI code, where generic code is augmented as needed with quirks for all kinds
+of devices.
+
+PMBus device capabilities auto-detection
+========================================
+
+For generic PMBus devices, code in pmbus.c attempts to auto-detect all supported
+PMBus commands. Auto-detection is somewhat limited, since there are simply too
+many variables to consider. For example, it is almost impossible to autodetect
+which PMBus commands are paged and which commands are replicated across all
+pages (see the PMBus specification for details on multi-page PMBus devices).
+
+For this reason, it often makes sense to provide a device specific driver if not
+all commands can be auto-detected. The data structures in this driver can be
+used to inform the core driver about functionality supported by individual
+chips.
+
+Some commands are always auto-detected. This applies to all limit commands
+(lcrit, min, max, and crit attributes) as well as associated alarm attributes.
+Limits and alarm attributes are auto-detected because there are simply too many
+possible combinations to provide a manual configuration interface.
+
+PMBus internal API
+==================
+
+The API between core and device specific PMBus code is defined in
+drivers/hwmon/pmbus/pmbus.h. In addition to the internal API, pmbus.h defines
+standard PMBus commands and virtual PMBus commands.
+
+Standard PMBus commands
+-----------------------
+
+Standard PMBus commands (commands values 0x00 to 0xff) are defined in the PMBUs
+specification.
+
+Virtual PMBus commands
+----------------------
+
+Virtual PMBus commands are provided to enable support for non-standard
+functionality which has been implemented by several chip vendors and is thus
+desirable to support.
+
+Virtual PMBus commands start with command value 0x100 and can thus easily be
+distinguished from standard PMBus commands (which can not have values larger
+than 0xff). Support for virtual PMBus commands is device specific and thus has
+to be implemented in device specific code.
+
+Virtual commands are named PMBUS_VIRT_xxx and start with PMBUS_VIRT_BASE. All
+virtual commands are word sized.
+
+There are currently two types of virtual commands.
+
+- READ commands are read-only; writes are either ignored or return an error.
+- RESET commands are read/write. Reading reset registers returns zero
+  (used for detection), writing any value causes the associated history to be
+  reset.
+
+Virtual commands have to be handled in device specific driver code. Chip driver
+code returns non-negative values if a virtual command is supported, or a
+negative error code if not. The chip driver may return -ENODATA or any other
+Linux error code in this case, though an error code other than -ENODATA is
+handled more efficiently and thus preferred. Either case, the calling PMBus
+core code will abort if the chip driver returns an error code when reading
+or writing virtual registers (in other words, the PMBus core code will never
+send a virtual command to a chip).
+
+PMBus driver information
+------------------------
+
+PMBus driver information, defined in struct pmbus_driver_info, is the main means
+for device specific drivers to pass information to the core PMBus driver.
+Specifically, it provides the following information.
+
+- For devices supporting its data in Direct Data Format, it provides coefficients
+  for converting register values into normalized data. This data is usually
+  provided by chip manufacturers in device datasheets.
+- Supported chip functionality can be provided to the core driver. This may be
+  necessary for chips which react badly if non-supported commands are executed,
+  and/or to speed up device detection and initialization.
+- Several function entry points are provided to support overriding and/or
+  augmenting generic command execution. This functionality can be used to map
+  non-standard PMBus commands to standard commands, or to augment standard
+  command return values with device specific information.
+
+  API functions
+  -------------
+
+  Functions provided by chip driver
+  ---------------------------------
+
+  All functions return the command return value (read) or zero (write) if
+  successful. A return value of -ENODATA indicates that there is no manufacturer
+  specific command, but that a standard PMBus command may exist. Any other
+  negative return value indicates that the commands does not exist for this
+  chip, and that no attempt should be made to read or write the standard
+  command.
+
+  As mentioned above, an exception to this rule applies to virtual commands,
+  which  _must_ be handled in driver specific code. See "Virtual PMBus Commands"
+  above for more details.
+
+  Command execution in the core PMBus driver code is as follows.
+
+	if (chip_access_function) {
+		status = chip_access_function();
+		if (status != -ENODATA)
+			return status;
+	}
+	if (command >= PMBUS_VIRT_BASE)	/* For word commands/registers only */
+		return -EINVAL;
+	return generic_access();
+
+  Chip drivers may provide pointers to the following functions in struct
+  pmbus_driver_info. All functions are optional.
+
+  int (*read_byte_data)(struct i2c_client *client, int page, int reg);
+
+  Read byte from page <page>, register <reg>.
+  <page> may be -1, which means "current page".
+
+  int (*read_word_data)(struct i2c_client *client, int page, int reg);
+
+  Read word from page <page>, register <reg>.
+
+  int (*write_word_data)(struct i2c_client *client, int page, int reg,
+		         u16 word);
+
+  Write word to page <page>, register <reg>.
+
+  int (*write_byte)(struct i2c_client *client, int page, u8 value);
+
+  Write byte to page <page>, register <reg>.
+  <page> may be -1, which means "current page".
+
+  int (*identify)(struct i2c_client *client, struct pmbus_driver_info *info);
+
+  Determine supported PMBus functionality. This function is only necessary
+  if a chip driver supports multiple chips, and the chip functionality is not
+  pre-determined. It is currently only used by the generic pmbus driver
+  (pmbus.c).
+
+  Functions exported by core driver
+  ---------------------------------
+
+  Chip drivers are expected to use the following functions to read or write
+  PMBus registers. Chip drivers may also use direct I2C commands. If direct I2C
+  commands are used, the chip driver code must not directly modify the current
+  page, since the selected page is cached in the core driver and the core driver
+  will assume that it is selected. Using pmbus_set_page() to select a new page
+  is mandatory.
+
+  int pmbus_set_page(struct i2c_client *client, u8 page);
+
+  Set PMBus page register to <page> for subsequent commands.
+
+  int pmbus_read_word_data(struct i2c_client *client, u8 page, u8 reg);
+
+  Read word data from <page>, <reg>. Similar to i2c_smbus_read_word_data(), but
+  selects page first.
+
+  int pmbus_write_word_data(struct i2c_client *client, u8 page, u8 reg,
+			    u16 word);
+
+  Write word data to <page>, <reg>. Similar to i2c_smbus_write_word_data(), but
+  selects page first.
+
+  int pmbus_read_byte_data(struct i2c_client *client, int page, u8 reg);
+
+  Read byte data from <page>, <reg>. Similar to i2c_smbus_read_byte_data(), but
+  selects page first. <page> may be -1, which means "current page".
+
+  int pmbus_write_byte(struct i2c_client *client, int page, u8 value);
+
+  Write byte data to <page>, <reg>. Similar to i2c_smbus_write_byte(), but
+  selects page first. <page> may be -1, which means "current page".
+
+  void pmbus_clear_faults(struct i2c_client *client);
+
+  Execute PMBus "Clear Fault" command on all chip pages.
+  This function calls the device specific write_byte function if defined.
+  Therefore, it must _not_ be called from that function.
+
+  bool pmbus_check_byte_register(struct i2c_client *client, int page, int reg);
+
+  Check if byte register exists. Return true if the register exists, false
+  otherwise.
+  This function calls the device specific write_byte function if defined to
+  obtain the chip status. Therefore, it must _not_ be called from that function.
+
+  bool pmbus_check_word_register(struct i2c_client *client, int page, int reg);
+
+  Check if word register exists. Return true if the register exists, false
+  otherwise.
+  This function calls the device specific write_byte function if defined to
+  obtain the chip status. Therefore, it must _not_ be called from that function.
+
+  int pmbus_do_probe(struct i2c_client *client, const struct i2c_device_id *id,
+                     struct pmbus_driver_info *info);
+
+  Execute probe function. Similar to standard probe function for other drivers,
+  with the pointer to struct pmbus_driver_info as additional argument. Calls
+  identify function if supported. Must only be called from device probe
+  function.
+
+  void pmbus_do_remove(struct i2c_client *client);
+
+  Execute driver remove function. Similar to standard driver remove function.
+
+  const struct pmbus_driver_info
+	*pmbus_get_driver_info(struct i2c_client *client);
+
+  Return pointer to struct pmbus_driver_info as passed to pmbus_do_probe().
+
+
+PMBus driver platform data
+==========================
+
+PMBus platform data is defined in include/linux/i2c/pmbus.h. Platform data
+currently only provides a flag field with a single bit used.
+
+#define PMBUS_SKIP_STATUS_CHECK (1 << 0)
+
+struct pmbus_platform_data {
+        u32 flags;              /* Device specific flags */
+};
+
+
+Flags
+-----
+
+PMBUS_SKIP_STATUS_CHECK
+
+During register detection, skip checking the status register for
+communication or command errors.
+
+Some PMBus chips respond with valid data when trying to read an unsupported
+register. For such chips, checking the status register is mandatory when
+trying to determine if a chip register exists or not.
+Other PMBus chips don't support the STATUS_CML register, or report
+communication errors for no explicable reason. For such chips, checking the
+status register must be disabled.
+
+Some i2c controllers do not support single-byte commands (write commands with
+no data, i2c_smbus_write_byte()). With such controllers, clearing the status
+register is impossible, and the PMBUS_SKIP_STATUS_CHECK flag must be set.

+Description
+-----------
+
+This driver supports hardware montoring for Intersil / Zilker Labs ZL6100 and
+compatible digital DC-DC controllers.
+
+The driver is a client driver to the core PMBus driver. Please see
+Documentation/hwmon/pmbus and Documentation.hwmon/pmbus-core for details
+on PMBus client drivers.
+
+
+Usage Notes
+-----------
+
+This driver does not auto-detect devices. You will have to instantiate the
+devices explicitly. Please see Documentation/i2c/instantiating-devices for
+details.
+
+WARNING: Do not access chip registers using the i2cdump command, and do not use
+any of the i2ctools commands on a command register used to save and restore
+configuration data (0x11, 0x12, 0x15, 0x16, and 0xf4). The chips supported by
+this driver interpret any access to those command registers (including read
+commands) as request to execute the command in question. Unless write accesses
+to those registers are protected, this may result in power loss, board resets,
+and/or Flash corruption. Worst case, your board may turn into a brick.
+
+
+Platform data support
+---------------------
+
+The driver supports standard PMBus driver platform data.
+
+
+Module parameters
+-----------------
+
+delay
+-----
+
+Some Intersil/Zilker Labs DC-DC controllers require a minimum interval between
+I2C bus accesses. According to Intersil, the minimum interval is 2 ms, though
+1 ms appears to be sufficient and has not caused any problems in testing.
+The problem is known to affect ZL6100, ZL2105, and ZL2008. It is known not to
+affect ZL2004 and ZL6105. The driver automatically sets the interval to 1 ms
+except for ZL2004 and ZL6105. To enable manual override, the driver provides a
+writeable module parameter, 'delay', which can be used to set the interval to
+a value between 0 and 65,535 microseconds.

+PINCTRL (PIN CONTROL) subsystem
+This document outlines the pin control subsystem in Linux
+
+This subsystem deals with:
+
+- Enumerating and naming controllable pins
+
+- Multiplexing of pins, pads, fingers (etc) see below for details
+
+The intention is to also deal with:
+
+- Software-controlled biasing and driving mode specific pins, such as
+  pull-up/down, open drain etc, load capacitance configuration when controlled
+  by software, etc.
+
+
+Top-level interface
+===================
+
+Definition of PIN CONTROLLER:
+
+- A pin controller is a piece of hardware, usually a set of registers, that
+  can control PINs. It may be able to multiplex, bias, set load capacitance,
+  set drive strength etc for individual pins or groups of pins.
+
+Definition of PIN:
+
+- PINS are equal to pads, fingers, balls or whatever packaging input or
+  output line you want to control and these are denoted by unsigned integers
+  in the range 0..maxpin. This numberspace is local to each PIN CONTROLLER, so
+  there may be several such number spaces in a system. This pin space may
+  be sparse - i.e. there may be gaps in the space with numbers where no
+  pin exists.
+
+When a PIN CONTROLLER is instatiated, it will register a descriptor to the
+pin control framework, and this descriptor contains an array of pin descriptors
+describing the pins handled by this specific pin controller.
+
+Here is an example of a PGA (Pin Grid Array) chip seen from underneath:
+
+        A   B   C   D   E   F   G   H
+
+   8    o   o   o   o   o   o   o   o

+
+To register a pin controller and name all the pins on this package we can do
+this in our driver:
+
+#include <linux/pinctrl/pinctrl.h>
+
+const struct pinctrl_pin_desc __refdata foo_pins[] = {
+      PINCTRL_PIN(0, "A1"),
+      PINCTRL_PIN(1, "A2"),
+      PINCTRL_PIN(2, "A3"),
+      ...
+      PINCTRL_PIN(61, "H6"),
+      PINCTRL_PIN(62, "H7"),
+      PINCTRL_PIN(63, "H8"),
+};
+
+static struct pinctrl_desc foo_desc = {
+	.name = "foo",
+	.pins = foo_pins,
+	.npins = ARRAY_SIZE(foo_pins),
+	.maxpin = 63,
+	.owner = THIS_MODULE,
+};
+
+int __init foo_probe(void)
+{
+	struct pinctrl_dev *pctl;
+
+	pctl = pinctrl_register(&foo_desc, <PARENT>, NULL);
+	if (IS_ERR(pctl))
+		pr_err("could not register foo pin driver\n");
+}
+
+Pins usually have fancier names than this. You can find these in the dataheet
+for your chip. Notice that the core pinctrl.h file provides a fancy macro
+called PINCTRL_PIN() to create the struct entries. As you can see I enumerated
+the pins from 0 in the upper left corner to 63 in the lower right corner,
+this enumeration was arbitrarily chosen, in practice you need to think
+through your numbering system so that it matches the layout of registers
+and such things in your driver, or the code may become complicated. You must
+also consider matching of offsets to the GPIO ranges that may be handled by
+the pin controller.
+
+For a padring with 467 pads, as opposed to actual pins, I used an enumeration
+like this, walking around the edge of the chip, which seems to be industry
+standard too (all these pads had names, too):
+
+
+     0 ..... 104
+   466        105
+     .        .
+     .        .
+   358        224
+    357 .... 225
+
+
+Pin groups
+==========
+
+Many controllers need to deal with groups of pins, so the pin controller
+subsystem has a mechanism for enumerating groups of pins and retrieving the
+actual enumerated pins that are part of a certain group.
+
+For example, say that we have a group of pins dealing with an SPI interface
+on { 0, 8, 16, 24 }, and a group of pins dealing with an I2C interface on pins
+on { 24, 25 }.
+
+These two groups are presented to the pin control subsystem by implementing
+some generic pinctrl_ops like this:
+
+#include <linux/pinctrl/pinctrl.h>
+
+struct foo_group {
+	const char *name;
+	const unsigned int *pins;
+	const unsigned num_pins;
+};
+
+static unsigned int spi0_pins[] = { 0, 8, 16, 24 };
+static unsigned int i2c0_pins[] = { 24, 25 };
+
+static const struct foo_group foo_groups[] = {
+	{
+		.name = "spi0_grp",
+		.pins = spi0_pins,
+		.num_pins = ARRAY_SIZE(spi0_pins),
+	},
+	{
+		.name = "i2c0_grp",
+		.pins = i2c0_pins,
+		.num_pins = ARRAY_SIZE(i2c0_pins),
+	},
+};
+
+
+static int foo_list_groups(struct pinctrl_dev *pctldev, unsigned selector)
+{
+	if (selector >= ARRAY_SIZE(foo_groups))
+		return -EINVAL;
+	return 0;
+}
+
+static const char *foo_get_group_name(struct pinctrl_dev *pctldev,
+				       unsigned selector)
+{
+	return foo_groups[selector].name;
+}
+
+static int foo_get_group_pins(struct pinctrl_dev *pctldev, unsigned selector,
+			       unsigned ** const pins,
+			       unsigned * const num_pins)
+{
+	*pins = (unsigned *) foo_groups[selector].pins;
+	*num_pins = foo_groups[selector].num_pins;
+	return 0;
+}
+
+static struct pinctrl_ops foo_pctrl_ops = {
+	.list_groups = foo_list_groups,
+	.get_group_name = foo_get_group_name,
+	.get_group_pins = foo_get_group_pins,
+};
+
+
+static struct pinctrl_desc foo_desc = {
+       ...
+       .pctlops = &foo_pctrl_ops,
+};
+
+The pin control subsystem will call the .list_groups() function repeatedly
+beginning on 0 until it returns non-zero to determine legal selectors, then
+it will call the other functions to retrieve the name and pins of the group.
+Maintaining the data structure of the groups is up to the driver, this is
+just a simple example - in practice you may need more entries in your group
+structure, for example specific register ranges associated with each group
+and so on.
+
+
+Interaction with the GPIO subsystem
+===================================
+
+The GPIO drivers may want to perform operations of various types on the same
+physical pins that are also registered as pin controller pins.
+
+Since the pin controller subsystem have its pinspace local to the pin
+controller we need a mapping so that the pin control subsystem can figure out
+which pin controller handles control of a certain GPIO pin. Since a single
+pin controller may be muxing several GPIO ranges (typically SoCs that have
+one set of pins but internally several GPIO silicon blocks, each modeled as
+a struct gpio_chip) any number of GPIO ranges can be added to a pin controller
+instance like this:
+
+struct gpio_chip chip_a;
+struct gpio_chip chip_b;
+
+static struct pinctrl_gpio_range gpio_range_a = {
+	.name = "chip a",
+	.id = 0,
+	.base = 32,
+	.npins = 16,
+	.gc = &chip_a;
+};
+
+static struct pinctrl_gpio_range gpio_range_a = {
+	.name = "chip b",
+	.id = 0,
+	.base = 48,
+	.npins = 8,
+	.gc = &chip_b;
+};
+
+
+{
+	struct pinctrl_dev *pctl;
+	...
+	pinctrl_add_gpio_range(pctl, &gpio_range_a);
+	pinctrl_add_gpio_range(pctl, &gpio_range_b);
+}
+
+So this complex system has one pin controller handling two different
+GPIO chips. Chip a has 16 pins and chip b has 8 pins. They are mapped in
+the global GPIO pin space at:
+
+chip a: [32 .. 47]
+chip b: [48 .. 55]
+
+When GPIO-specific functions in the pin control subsystem are called, these
+ranges will be used to look up the apropriate pin controller by inspecting
+and matching the pin to the pin ranges across all controllers. When a
+pin controller handling the matching range is found, GPIO-specific functions
+will be called on that specific pin controller.
+
+For all functionalities dealing with pin biasing, pin muxing etc, the pin
+controller subsystem will subtract the range's .base offset from the passed
+in gpio pin number, and pass that on to the pin control driver, so the driver
+will get an offset into its handled number range. Further it is also passed
+the range ID value, so that the pin controller knows which range it should
+deal with.
+
+For example: if a user issues pinctrl_gpio_set_foo(50), the pin control
+subsystem will find that the second range on this pin controller matches,
+subtract the base 48 and call the
+pinctrl_driver_gpio_set_foo(pinctrl, range, 2) where the latter function has
+this signature:
+
+int pinctrl_driver_gpio_set_foo(struct pinctrl_dev *pctldev,
+    struct pinctrl_gpio_range *rangeid,
+    unsigned offset);
+
+Now the driver knows that we want to do some GPIO-specific operation on the
+second GPIO range handled by "chip b", at offset 2 in that specific range.
+
+(If the GPIO subsystem is ever refactored to use a local per-GPIO controller
+pin space, this mapping will need to be augmented accordingly.)
+
+
+PINMUX interfaces
+=================
+
+These calls use the pinmux_* naming prefix.  No other calls should use that
+prefix.
+
+
+What is pinmuxing?
+==================
+
+PINMUX, also known as padmux, ballmux, alternate functions or mission modes
+is a way for chip vendors producing some kind of electrical packages to use
+a certain physical pin (ball, pad, finger, etc) for multiple mutually exclusive
+functions, depending on the application. By "application" in this context
+we usually mean a way of soldering or wiring the package into an electronic
+system, even though the framework makes it possible to also change the function
+at runtime.
+
+Here is an example of a PGA (Pin Grid Array) chip seen from underneath:
+
+        A   B   C   D   E   F   G   H
+      +---+
+   8  | o | o   o   o   o   o   o   o

+      |   |
+   6  | o | o   o   o   o   o   o   o
+      +---+---+
+   5  | o | o | o   o   o   o   o   o
+      +---+---+               +---+
+   4    o   o   o   o   o   o | o | o
+                              |   |
+   3    o   o   o   o   o   o | o | o
+                              |   |
+   2    o   o   o   o   o   o | o | o
+      +-------+-------+-------+---+---+
+   1  | o   o | o   o | o   o | o | o |
+      +-------+-------+-------+---+---+
+
+This is not tetris. The game to think of is chess. Not all PGA/BGA packages
+are chessboard-like, big ones have "holes" in some arrangement according to
+different design patterns, but we're using this as a simple example. Of the
+pins you see some will be taken by things like a few VCC and GND to feed power
+to the chip, and quite a few will be taken by large ports like an external
+memory interface. The remaining pins will often be subject to pin multiplexing.
+
+The example 8x8 PGA package above will have pin numbers 0 thru 63 assigned to
+its physical pins. It will name the pins { A1, A2, A3 ... H6, H7, H8 } using
+pinctrl_register_pins() and a suitable data set as shown earlier.
+
+In this 8x8 BGA package the pins { A8, A7, A6, A5 } can be used as an SPI port
+(these are four pins: CLK, RXD, TXD, FRM). In that case, pin B5 can be used as
+some general-purpose GPIO pin. However, in another setting, pins { A5, B5 } can
+be used as an I2C port (these are just two pins: SCL, SDA). Needless to say,
+we cannot use the SPI port and I2C port at the same time. However in the inside
+of the package the silicon performing the SPI logic can alternatively be routed
+out on pins { G4, G3, G2, G1 }.
+
+On the botton row at { A1, B1, C1, D1, E1, F1, G1, H1 } we have something
+special - it's an external MMC bus that can be 2, 4 or 8 bits wide, and it will
+consume 2, 4 or 8 pins respectively, so either { A1, B1 } are taken or
+{ A1, B1, C1, D1 } or all of them. If we use all 8 bits, we cannot use the SPI
+port on pins { G4, G3, G2, G1 } of course.
+
+This way the silicon blocks present inside the chip can be multiplexed "muxed"
+out on different pin ranges. Often contemporary SoC (systems on chip) will
+contain several I2C, SPI, SDIO/MMC, etc silicon blocks that can be routed to
+different pins by pinmux settings.
+
+Since general-purpose I/O pins (GPIO) are typically always in shortage, it is
+common to be able to use almost any pin as a GPIO pin if it is not currently
+in use by some other I/O port.
+
+
+Pinmux conventions
+==================
+
+The purpose of the pinmux functionality in the pin controller subsystem is to
+abstract and provide pinmux settings to the devices you choose to instantiate
+in your machine configuration. It is inspired by the clk, GPIO and regulator
+subsystems, so devices will request their mux setting, but it's also possible
+to request a single pin for e.g. GPIO.
+
+Definitions:
+
+- FUNCTIONS can be switched in and out by a driver residing with the pin
+  control subsystem in the drivers/pinctrl/* directory of the kernel. The
+  pin control driver knows the possible functions. In the example above you can
+  identify three pinmux functions, one for spi, one for i2c and one for mmc.
+
+- FUNCTIONS are assumed to be enumerable from zero in a one-dimensional array.
+  In this case the array could be something like: { spi0, i2c0, mmc0 }
+  for the three available functions.
+
+- FUNCTIONS have PIN GROUPS as defined on the generic level - so a certain
+  function is *always* associated with a certain set of pin groups, could
+  be just a single one, but could also be many. In the example above the
+  function i2c is associated with the pins { A5, B5 }, enumerated as
+  { 24, 25 } in the controller pin space.
+
+  The Function spi is associated with pin groups { A8, A7, A6, A5 }
+  and { G4, G3, G2, G1 }, which are enumerated as { 0, 8, 16, 24 } and
+  { 38, 46, 54, 62 } respectively.
+
+  Group names must be unique per pin controller, no two groups on the same
+  controller may have the same name.
+
+- The combination of a FUNCTION and a PIN GROUP determine a certain function
+  for a certain set of pins. The knowledge of the functions and pin groups
+  and their machine-specific particulars are kept inside the pinmux driver,
+  from the outside only the enumerators are known, and the driver core can:
+
+  - Request the name of a function with a certain selector (>= 0)
+  - A list of groups associated with a certain function
+  - Request that a certain group in that list to be activated for a certain
+    function
+
+  As already described above, pin groups are in turn self-descriptive, so
+  the core will retrieve the actual pin range in a certain group from the
+  driver.
+
+- FUNCTIONS and GROUPS on a certain PIN CONTROLLER are MAPPED to a certain
+  device by the board file, device tree or similar machine setup configuration
+  mechanism, similar to how regulators are connected to devices, usually by
+  name. Defining a pin controller, function and group thus uniquely identify
+  the set of pins to be used by a certain device. (If only one possible group
+  of pins is available for the function, no group name need to be supplied -
+  the core will simply select the first and only group available.)
+
+  In the example case we can define that this particular machine shall
+  use device spi0 with pinmux function fspi0 group gspi0 and i2c0 on function
+  fi2c0 group gi2c0, on the primary pin controller, we get mappings
+  like these:
+
+  {
+    {"map-spi0", spi0, pinctrl0, fspi0, gspi0},
+    {"map-i2c0", i2c0, pinctrl0, fi2c0, gi2c0}
+  }
+
+  Every map must be assigned a symbolic name, pin controller and function.
+  The group is not compulsory - if it is omitted the first group presented by
+  the driver as applicable for the function will be selected, which is
+  useful for simple cases.
+
+  The device name is present in map entries tied to specific devices. Maps
+  without device names are referred to as SYSTEM pinmuxes, such as can be taken
+  by the machine implementation on boot and not tied to any specific device.
+
+  It is possible to map several groups to the same combination of device,
+  pin controller and function. This is for cases where a certain function on
+  a certain pin controller may use different sets of pins in different
+  configurations.
+
+- PINS for a certain FUNCTION using a certain PIN GROUP on a certain
+  PIN CONTROLLER are provided on a first-come first-serve basis, so if some
+  other device mux setting or GPIO pin request has already taken your physical
+  pin, you will be denied the use of it. To get (activate) a new setting, the
+  old one has to be put (deactivated) first.
+
+Sometimes the documentation and hardware registers will be oriented around
+pads (or "fingers") rather than pins - these are the soldering surfaces on the
+silicon inside the package, and may or may not match the actual number of
+pins/balls underneath the capsule. Pick some enumeration that makes sense to
+you. Define enumerators only for the pins you can control if that makes sense.
+
+Assumptions:
+
+We assume that the number possible function maps to pin groups is limited by
+the hardware. I.e. we assume that there is no system where any function can be
+mapped to any pin, like in a phone exchange. So the available pins groups for
+a certain function will be limited to a few choices (say up to eight or so),
+not hundreds or any amount of choices. This is the characteristic we have found
+by inspecting available pinmux hardware, and a necessary assumption since we
+expect pinmux drivers to present *all* possible function vs pin group mappings
+to the subsystem.
+
+
+Pinmux drivers
+==============
+
+The pinmux core takes care of preventing conflicts on pins and calling
+the pin controller driver to execute different settings.
+
+It is the responsibility of the pinmux driver to impose further restrictions
+(say for example infer electronic limitations due to load etc) to determine
+whether or not the requested function can actually be allowed, and in case it
+is possible to perform the requested mux setting, poke the hardware so that
+this happens.
+
+Pinmux drivers are required to supply a few callback functions, some are
+optional. Usually the enable() and disable() functions are implemented,
+writing values into some certain registers to activate a certain mux setting
+for a certain pin.
+
+A simple driver for the above example will work by setting bits 0, 1, 2, 3 or 4
+into some register named MUX to select a certain function with a certain
+group of pins would work something like this:

+
+In the example activating muxing 0 and 1 at the same time setting bits
+0 and 1, uses one pin in common so they would collide.
+
+The beauty of the pinmux subsystem is that since it keeps track of all
+pins and who is using them, it will already have denied an impossible
+request like that, so the driver does not need to worry about such
+things - when it gets a selector passed in, the pinmux subsystem makes
+sure no other device or GPIO assignment is already using the selected
+pins. Thus bits 0 and 1 in the control register will never be set at the
+same time.
+
+All the above functions are mandatory to implement for a pinmux driver.
+
+
+Pinmux interaction with the GPIO subsystem
+==========================================
+
+The function list could become long, especially if you can convert every
+individual pin into a GPIO pin independent of any other pins, and then try
+the approach to define every pin as a function.
+
+In this case, the function array would become 64 entries for each GPIO
+setting and then the device functions.
+
+For this reason there is an additional function a pinmux driver can implement
+to enable only GPIO on an individual pin: .gpio_request_enable(). The same
+.free() function as for other functions is assumed to be usable also for
+GPIO pins.
+
+This function will pass in the affected GPIO range identified by the pin
+controller core, so you know which GPIO pins are being affected by the request
+operation.
+
+Alternatively it is fully allowed to use named functions for each GPIO
+pin, the pinmux_request_gpio() will attempt to obtain the function "gpioN"
+where "N" is the global GPIO pin number if no special GPIO-handler is
+registered.
+
+
+Pinmux board/machine configuration
+==================================
+
+Boards and machines define how a certain complete running system is put
+together, including how GPIOs and devices are muxed, how regulators are
+constrained and how the clock tree looks. Of course pinmux settings are also
+part of this.
+
+A pinmux config for a machine looks pretty much like a simple regulator
+configuration, so for the example array above we want to enable i2c and
+spi on the second function mapping:
+
+#include <linux/pinctrl/machine.h>
+
+static struct pinmux_map pmx_mapping[] = {
+	{
+		.ctrl_dev_name = "pinctrl.0",
+		.function = "spi0",
+		.dev_name = "foo-spi.0",
+	},
+	{
+		.ctrl_dev_name = "pinctrl.0",
+		.function = "i2c0",
+		.dev_name = "foo-i2c.0",
+	},
+	{
+		.ctrl_dev_name = "pinctrl.0",
+		.function = "mmc0",
+		.dev_name = "foo-mmc.0",
+	},
+};
+
+The dev_name here matches to the unique device name that can be used to look
+up the device struct (just like with clockdev or regulators). The function name
+must match a function provided by the pinmux driver handling this pin range.
+
+As you can see we may have several pin controllers on the system and thus
+we need to specify which one of them that contain the functions we wish
+to map. The map can also use struct device * directly, so there is no
+inherent need to use strings to specify .dev_name or .ctrl_dev_name, these
+are for the situation where you do not have a handle to the struct device *,
+for example if they are not yet instantiated or cumbersome to obtain.
+
+You register this pinmux mapping to the pinmux subsystem by simply:
+
+       ret = pinmux_register_mappings(&pmx_mapping, ARRAY_SIZE(pmx_mapping));
+
+Since the above construct is pretty common there is a helper macro to make
+it even more compact which assumes you want to use pinctrl.0 and position
+0 for mapping, for example:
+
+static struct pinmux_map pmx_mapping[] = {
+       PINMUX_MAP_PRIMARY("I2CMAP", "i2c0", "foo-i2c.0"),
+};
+
+
+Complex mappings
+================
+
+As it is possible to map a function to different groups of pins an optional
+.group can be specified like this:
+
+...
+{
+	.name = "spi0-pos-A",
+	.ctrl_dev_name = "pinctrl.0",
+	.function = "spi0",
+	.group = "spi0_0_grp",
+	.dev_name = "foo-spi.0",
+},
+{
+	.name = "spi0-pos-B",
+	.ctrl_dev_name = "pinctrl.0",
+	.function = "spi0",
+	.group = "spi0_1_grp",
+	.dev_name = "foo-spi.0",
+},
+...
+
+This example mapping is used to switch between two positions for spi0 at
+runtime, as described further below under the heading "Runtime pinmuxing".
+
+Further it is possible to match several groups of pins to the same function
+for a single device, say for example in the mmc0 example above, where you can
+additively expand the mmc0 bus from 2 to 4 to 8 pins. If we want to use all
+three groups for a total of 2+2+4 = 8 pins (for an 8-bit MMC bus as is the
+case), we define a mapping like this:
+
+...
+{
+	.name "2bit"
+	.ctrl_dev_name = "pinctrl.0",
+	.function = "mmc0",
+	.group = "mmc0_0_grp",
+	.dev_name = "foo-mmc.0",
+},
+{
+	.name "4bit"
+	.ctrl_dev_name = "pinctrl.0",
+	.function = "mmc0",
+	.group = "mmc0_0_grp",
+	.dev_name = "foo-mmc.0",
+},
+{
+	.name "4bit"
+	.ctrl_dev_name = "pinctrl.0",
+	.function = "mmc0",
+	.group = "mmc0_1_grp",
+	.dev_name = "foo-mmc.0",
+},
+{
+	.name "8bit"
+	.ctrl_dev_name = "pinctrl.0",
+	.function = "mmc0",
+	.group = "mmc0_0_grp",
+	.dev_name = "foo-mmc.0",
+},
+{
+	.name "8bit"
+	.ctrl_dev_name = "pinctrl.0",
+	.function = "mmc0",
+	.group = "mmc0_1_grp",
+	.dev_name = "foo-mmc.0",
+},
+{
+	.name "8bit"
+	.ctrl_dev_name = "pinctrl.0",
+	.function = "mmc0",
+	.group = "mmc0_2_grp",
+	.dev_name = "foo-mmc.0",
+},
+...
+
+The result of grabbing this mapping from the device with something like
+this (see next paragraph):
+
+	pmx = pinmux_get(&device, "8bit");
+
+Will be that you activate all the three bottom records in the mapping at
+once. Since they share the same name, pin controller device, funcion and
+device, and since we allow multiple groups to match to a single device, they
+all get selected, and they all get enabled and disable simultaneously by the
+pinmux core.
+
+
+Pinmux requests from drivers
+============================
+
+Generally it is discouraged to let individual drivers get and enable pinmuxes.
+So if possible, handle the pinmuxes in platform code or some other place where
+you have access to all the affected struct device * pointers. In some cases
+where a driver needs to switch between different mux mappings at runtime
+this is not possible.
+
+A driver may request a certain mux to be activated, usually just the default
+mux like this:
+
+#include <linux/pinctrl/pinmux.h>
+
+struct foo_state {
+       struct pinmux *pmx;
+       ...
+};
+
+foo_probe()
+{
+	/* Allocate a state holder named "state" etc */
+	struct pinmux pmx;
+
+	pmx = pinmux_get(&device, NULL);
+	if IS_ERR(pmx)
+		return PTR_ERR(pmx);
+	pinmux_enable(pmx);
+
+	state->pmx = pmx;
+}
+
+foo_remove()
+{
+	pinmux_disable(state->pmx);
+	pinmux_put(state->pmx);
+}
+
+If you want to grab a specific mux mapping and not just the first one found for
+this device you can specify a specific mapping name, for example in the above
+example the second i2c0 setting: pinmux_get(&device, "spi0-pos-B");
+
+This get/enable/disable/put sequence can just as well be handled by bus drivers
+if you don't want each and every driver to handle it and you know the
+arrangement on your bus.
+
+The semantics of the get/enable respective disable/put is as follows:
+
+- pinmux_get() is called in process context to reserve the pins affected with
+  a certain mapping and set up the pinmux core and the driver. It will allocate
+  a struct from the kernel memory to hold the pinmux state.
+
+- pinmux_enable()/pinmux_disable() is quick and can be called from fastpath
+  (irq context) when you quickly want to set up/tear down the hardware muxing
+  when running a device driver. Usually it will just poke some values into a
+  register.
+
+- pinmux_disable() is called in process context to tear down the pin requests
+  and release the state holder struct for the mux setting.
+
+Usually the pinmux core handled the get/put pair and call out to the device
+drivers bookkeeping operations, like checking available functions and the
+associated pins, whereas the enable/disable pass on to the pin controller
+driver which takes care of activating and/or deactivating the mux setting by
+quickly poking some registers.
+
+The pins are allocated for your device when you issue the pinmux_get() call,
+after this you should be able to see this in the debugfs listing of all pins.
+
+
+System pinmux hogging
+=====================
+
+A system pinmux map entry, i.e. a pinmux setting that does not have a device
+associated with it, can be hogged by the core when the pin controller is
+registered. This means that the core will attempt to call pinmux_get() and
+pinmux_enable() on it immediately after the pin control device has been
+registered.
+
+This is enabled by simply setting the .hog_on_boot field in the map to true,
+like this:
+
+{
+	.name "POWERMAP"
+	.ctrl_dev_name = "pinctrl.0",
+	.function = "power_func",
+	.hog_on_boot = true,
+},
+
+Since it may be common to request the core to hog a few always-applicable
+mux settings on the primary pin controller, there is a convenience macro for
+this:
+
+PINMUX_MAP_PRIMARY_SYS_HOG("POWERMAP", "power_func")
+
+This gives the exact same result as the above construction.
+
+
+Runtime pinmuxing
+=================
+
+It is possible to mux a certain function in and out at runtime, say to move
+an SPI port from one set of pins to another set of pins. Say for example for
+spi0 in the example above, we expose two different groups of pins for the same
+function, but with different named in the mapping as described under
+"Advanced mapping" above. So we have two mappings named "spi0-pos-A" and
+"spi0-pos-B".
+
+This snippet first muxes the function in the pins defined by group A, enables
+it, disables and releases it, and muxes it in on the pins defined by group B:
+
+foo_switch()
+{
+	struct pinmux pmx;
+
+	/* Enable on position A */
+	pmx = pinmux_get(&device, "spi0-pos-A");
+	if IS_ERR(pmx)
+		return PTR_ERR(pmx);
+	pinmux_enable(pmx);
+
+	/* This releases the pins again */
+	pinmux_disable(pmx);
+	pinmux_put(pmx);
+
+	/* Enable on position B */
+	pmx = pinmux_get(&device, "spi0-pos-B");
+	if IS_ERR(pmx)
+		return PTR_ERR(pmx);
+	pinmux_enable(pmx);
+	...
+}
+
+The above has to be done from process context.

+
+So, as can be seen from the two diagrams (the parts marked as "Common code"),
+regular CPU hotplug and the suspend code path converge at the _cpu_down() and
+_cpu_up() functions. They differ in the arguments passed to these functions,
+in that during regular CPU hotplug, 0 is passed for the 'tasks_frozen'
+argument. But during suspend, since the tasks are already frozen by the time
+the non-boot CPUs are offlined or onlined, the _cpu_*() functions are called
+with the 'tasks_frozen' argument set to 1.
+[See below for some known issues regarding this.]

+
+
+
+II. What are the issues involved in CPU hotplug?
+    -------------------------------------------
+
+There are some interesting situations involving CPU hotplug and microcode
+update on the CPUs, as discussed below:
+
+[Please bear in mind that the kernel requests the microcode images from
+userspace, using the request_firmware() function defined in
+drivers/base/firmware_class.c]
+
+
+a. When all the CPUs are identical:
+
+   This is the most common situation and it is quite straightforward: we want
+   to apply the same microcode revision to each of the CPUs.
+   To give an example of x86, the collect_cpu_info() function defined in
+   arch/x86/kernel/microcode_core.c helps in discovering the type of the CPU
+   and thereby in applying the correct microcode revision to it.
+   But note that the kernel does not maintain a common microcode image for the
+   all CPUs, in order to handle case 'b' described below.
+
+
+b. When some of the CPUs are different than the rest:
+
+   In this case since we probably need to apply different microcode revisions
+   to different CPUs, the kernel maintains a copy of the correct microcode
+   image for each CPU (after appropriate CPU type/model discovery using
+   functions such as collect_cpu_info()).
+
+
+c. When a CPU is physically hot-unplugged and a new (and possibly different
+   type of) CPU is hot-plugged into the system:
+
+   In the current design of the kernel, whenever a CPU is taken offline during
+   a regular CPU hotplug operation, upon receiving the CPU_DEAD notification
+   (which is sent by the CPU hotplug code), the microcode update driver's
+   callback for that event reacts by freeing the kernel's copy of the
+   microcode image for that CPU.
+
+   Hence, when a new CPU is brought online, since the kernel finds that it
+   doesn't have the microcode image, it does the CPU type/model discovery
+   afresh and then requests the userspace for the appropriate microcode image
+   for that CPU, which is subsequently applied.
+
+   For example, in x86, the mc_cpu_callback() function (which is the microcode
+   update driver's callback registered for CPU hotplug events) calls
+   microcode_update_cpu() which would call microcode_init_cpu() in this case,
+   instead of microcode_resume_cpu() when it finds that the kernel doesn't
+   have a valid microcode image. This ensures that the CPU type/model
+   discovery is performed and the right microcode is applied to the CPU after
+   getting it from userspace.
+
+
+d. Handling microcode update during suspend/hibernate:
+
+   Strictly speaking, during a CPU hotplug operation which does not involve
+   physically removing or inserting CPUs, the CPUs are not actually powered
+   off during a CPU offline. They are just put to the lowest C-states possible.
+   Hence, in such a case, it is not really necessary to re-apply microcode
+   when the CPUs are brought back online, since they wouldn't have lost the
+   image during the CPU offline operation.
+
+   This is the usual scenario encountered during a resume after a suspend.
+   However, in the case of hibernation, since all the CPUs are completely
+   powered off, during restore it becomes necessary to apply the microcode
+   images to all the CPUs.
+
+   [Note that we don't expect someone to physically pull out nodes and insert
+   nodes with a different type of CPUs in-between a suspend-resume or a
+   hibernate/restore cycle.]
+
+   In the current design of the kernel however, during a CPU offline operation
+   as part of the suspend/hibernate cycle (the CPU_DEAD_FROZEN notification),
+   the existing copy of microcode image in the kernel is not freed up.
+   And during the CPU online operations (during resume/restore), since the
+   kernel finds that it already has copies of the microcode images for all the
+   CPUs, it just applies them to the CPUs, avoiding any re-discovery of CPU
+   type/model and the need for validating whether the microcode revisions are
+   right for the CPUs or not (due to the above assumption that physical CPU
+   hotplug will not be done in-between suspend/resume or hibernate/restore
+   cycles).
+
+
+III. Are there any known problems when regular CPU hotplug and suspend race
+     with each other?
+
+Yes, they are listed below:
+
+1. When invoking regular CPU hotplug, the 'tasks_frozen' argument passed to
+   the _cpu_down() and _cpu_up() functions is *always* 0.
+   This might not reflect the true current state of the system, since the
+   tasks could have been frozen by an out-of-band event such as a suspend

+   to a suspend operation in progress at the same time, then we could hit the
+   situation described below:
+
+    * A regular cpu online operation continues its journey from userspace
+      into the kernel, since the freezing has not yet begun.
+    * Then freezer gets to work and freezes userspace.
+    * If cpu online has not yet completed the microcode update stuff by now,
+      it will now start waiting on the frozen userspace in the
+      TASK_UNINTERRUPTIBLE state, in order to get the microcode image.
+    * Now the freezer continues and tries to freeze the remaining tasks. But
+      due to this wait mentioned above, the freezer won't be able to freeze
+      the cpu online hotplug task and hence freezing of tasks fails.
+
+   As a result of this task freezing failure, the suspend operation gets
+   aborted.

+CFS Bandwidth Control
+=====================
+
+[ This document only discusses CPU bandwidth control for SCHED_NORMAL.
+  The SCHED_RT case is covered in Documentation/scheduler/sched-rt-group.txt ]
+
+CFS bandwidth control is a CONFIG_FAIR_GROUP_SCHED extension which allows the
+specification of the maximum CPU bandwidth available to a group or hierarchy.
+
+The bandwidth allowed for a group is specified using a quota and period. Within
+each given "period" (microseconds), a group is allowed to consume only up to
+"quota" microseconds of CPU time.  When the CPU bandwidth consumption of a
+group exceeds this limit (for that period), the tasks belonging to its
+hierarchy will be throttled and are not allowed to run again until the next
+period.
+
+A group's unused runtime is globally tracked, being refreshed with quota units
+above at each period boundary.  As threads consume this bandwidth it is
+transferred to cpu-local "silos" on a demand basis.  The amount transferred
+within each of these updates is tunable and described as the "slice".
+
+Management
+----------
+Quota and period are managed within the cpu subsystem via cgroupfs.
+
+cpu.cfs_quota_us: the total available run-time within a period (in microseconds)
+cpu.cfs_period_us: the length of a period (in microseconds)
+cpu.stat: exports throttling statistics [explained further below]
+
+The default values are:
+	cpu.cfs_period_us=100ms
+	cpu.cfs_quota=-1
+
+A value of -1 for cpu.cfs_quota_us indicates that the group does not have any
+bandwidth restriction in place, such a group is described as an unconstrained
+bandwidth group.  This represents the traditional work-conserving behavior for
+CFS.
+
+Writing any (valid) positive value(s) will enact the specified bandwidth limit.
+The minimum quota allowed for the quota or period is 1ms.  There is also an
+upper bound on the period length of 1s.  Additional restrictions exist when
+bandwidth limits are used in a hierarchical fashion, these are explained in
+more detail below.
+
+Writing any negative value to cpu.cfs_quota_us will remove the bandwidth limit
+and return the group to an unconstrained state once more.
+
+Any updates to a group's bandwidth specification will result in it becoming
+unthrottled if it is in a constrained state.
+
+System wide settings
+--------------------
+For efficiency run-time is transferred between the global pool and CPU local
+"silos" in a batch fashion.  This greatly reduces global accounting pressure
+on large systems.  The amount transferred each time such an update is required
+is described as the "slice".
+
+This is tunable via procfs:
+	/proc/sys/kernel/sched_cfs_bandwidth_slice_us (default=5ms)
+
+Larger slice values will reduce transfer overheads, while smaller values allow
+for more fine-grained consumption.
+
+Statistics
+----------
+A group's bandwidth statistics are exported via 3 fields in cpu.stat.
+
+cpu.stat:
+- nr_periods: Number of enforcement intervals that have elapsed.
+- nr_throttled: Number of times the group has been throttled/limited.
+- throttled_time: The total time duration (in nanoseconds) for which entities
+  of the group have been throttled.
+
+This interface is read-only.
+
+Hierarchical considerations
+---------------------------
+The interface enforces that an individual entity's bandwidth is always
+attainable, that is: max(c_i) <= C. However, over-subscription in the
+aggregate case is explicitly allowed to enable work-conserving semantics
+within a hierarchy.
+  e.g. \Sum (c_i) may exceed C
+[ Where C is the parent's bandwidth, and c_i its children ]
+
+
+There are two ways in which a group may become throttled:
+	a. it fully consumes its own quota within a period
+	b. a parent's quota is fully consumed within its period
+
+In case b) above, even though the child may have runtime remaining it will not
+be allowed to until the parent's runtime is refreshed.
+
+Examples
+--------
+1. Limit a group to 1 CPU worth of runtime.
+
+	If period is 250ms and quota is also 250ms, the group will get
+	1 CPU worth of runtime every 250ms.
+
+	# echo 250000 > cpu.cfs_quota_us /* quota = 250ms */
+	# echo 250000 > cpu.cfs_period_us /* period = 250ms */
+
+2. Limit a group to 2 CPUs worth of runtime on a multi-CPU machine.
+
+	With 500ms period and 1000ms quota, the group can get 2 CPUs worth of
+	runtime every 500ms.
+
+	# echo 1000000 > cpu.cfs_quota_us /* quota = 1000ms */
+	# echo 500000 > cpu.cfs_period_us /* period = 500ms */
+
+	The larger period here allows for increased burst capacity.
+
+3. Limit a group to 20% of 1 CPU.
+
+	With 50ms period, 10ms quota will be equivalent to 20% of 1 CPU.
+
+	# echo 10000 > cpu.cfs_quota_us /* quota = 10ms */
+	# echo 50000 > cpu.cfs_period_us /* period = 50ms */
+
+	By using a small period here we are ensuring a consistent latency
+	response at the expense of burst capacity.

+- Convert interrupt handler to per-ep-thread-irq

+  As it turns out some DWC3-commands ~1ms to complete. Currently we spin
+  until the command completes which is bad.
+
+  Implementation idea:
+  - dwc core implements a demultiplexing irq chip for interrupts per
+    endpoint. The interrupt numbers are allocated during probe and belong
+    to the device. If MSI provides per-endpoint interrupt this dummy
+    interrupt chip can be replaced with "real" interrupts.
+  - interrupts are requested / allocated on usb_ep_enable() and removed on
+    usb_ep_disable(). Worst case are 32 interrupts, the lower limit is two
+    for ep0/1.
+  - dwc3_send_gadget_ep_cmd() will sleep in wait_for_completion_timeout()
+    until the command completes.
+  - the interrupt handler is split into the following pieces:
+    - primary handler of the device
+      goes through every event and calls generic_handle_irq() for event
+      it. On return from generic_handle_irq() in acknowledges the event
+      counter so interrupt goes away (eventually).
+
+    - threaded handler of the device
+      none
+
+    - primary handler of the EP-interrupt
+      reads the event and tries to process it. Everything that requries
+      sleeping is handed over to the Thread. The event is saved in an
+      per-endpoint data-structure.
+      We probably have to pay attention not to process events once we
+      handed something to thread so we don't process event X prio Y
+      where X > Y.
+
+    - threaded handler of the EP-interrupt
+      handles the remaining EP work which might sleep such as waiting
+      for command completion.
+
+  Latency:
+   There should be no increase in latency since the interrupt-thread has a
+   high priority and will be run before an average task in user land
+   (except the user changed priorities).

+Virtio PCI Card Specification
+v0.9.1 DRAFT
+-
+
+Rusty Russell <rusty@rustcorp.com.au>IBM Corporation (Editor)
+
+2011 August 1.
+
+Purpose and Description
+
+This document describes the specifications of the “virtio� family
+of PCI[LaTeX Command: nomenclature] devices. These are devices
+are found in virtual environments[LaTeX Command: nomenclature],
+yet by design they are not all that different from physical PCI
+devices, and this document treats them as such. This allows the
+guest to use standard PCI drivers and discovery mechanisms.
+
+The purpose of virtio and this specification is that virtual
+environments and guests should have a straightforward, efficient,
+standard and extensible mechanism for virtual devices, rather
+than boutique per-environment or per-OS mechanisms.
+
+  Straightforward: Virtio PCI devices use normal PCI mechanisms
+  of interrupts and DMA which should be familiar to any device
+  driver author. There is no exotic page-flipping or COW
+  mechanism: it's just a PCI device.[footnote:
+This lack of page-sharing implies that the implementation of the
+device (e.g. the hypervisor or host) needs full access to the
+guest memory. Communication with untrusted parties (i.e.
+inter-guest communication) requires copying.
+]
+
+  Efficient: Virtio PCI devices consist of rings of descriptors
+  for input and output, which are neatly separated to avoid cache
+  effects from both guest and device writing to the same cache
+  lines.
+
+  Standard: Virtio PCI makes no assumptions about the environment
+  in which it operates, beyond supporting PCI. In fact the virtio
+  devices specified in the appendices do not require PCI at all:
+  they have been implemented on non-PCI buses.[footnote:
+The Linux implementation further separates the PCI virtio code
+from the specific virtio drivers: these drivers are shared with
+the non-PCI implementations (currently lguest and S/390).
+]
+
+  Extensible: Virtio PCI devices contain feature bits which are
+  acknowledged by the guest operating system during device setup.
+  This allows forwards and backwards compatibility: the device
+  offers all the features it knows about, and the driver
+  acknowledges those it understands and wishes to use.
+
+  Virtqueues
+
+The mechanism for bulk data transport on virtio PCI devices is
+pretentiously called a virtqueue. Each device can have zero or
+more virtqueues: for example, the network device has one for
+transmit and one for receive.
+
+Each virtqueue occupies two or more physically-contiguous pages
+(defined, for the purposes of this specification, as 4096 bytes),
+and consists of three parts:
+
+
++-------------------+-----------------------------------+-----------+
+| Descriptor Table  |   Available Ring     (padding)    | Used Ring |
++-------------------+-----------------------------------+-----------+
+
+
+When the driver wants to send buffers to the device, it puts them
+in one or more slots in the descriptor table, and writes the
+descriptor indices into the available ring. It then notifies the
+device. When the device has finished with the buffers, it writes
+the descriptors into the used ring, and sends an interrupt.
+
+Specification
+
+  PCI Discovery
+
+Any PCI device with Vendor ID 0x1AF4, and Device ID 0x1000
+through 0x103F inclusive is a virtio device[footnote:
+The actual value within this range is ignored
+]. The device must also have a Revision ID of 0 to match this
+specification.
+
+The Subsystem Device ID indicates which virtio device is
+supported by the device. The Subsystem Vendor ID should reflect
+the PCI Vendor ID of the environment (it's currently only used
+for informational purposes by the guest).

+
+  Device Configuration
+
+To configure the device, we use the first I/O region of the PCI
+device. This contains a virtio header followed by a
+device-specific region.
+
+There may be different widths of accesses to the I/O region; the “
+natural� access method for each field in the virtio header must
+be used (i.e. 32-bit accesses for 32-bit fields, etc), but the
+device-specific region can be accessed using any width accesses,
+and should obtain the same results.
+
+Note that this is possible because while the virtio header is PCI
+(i.e. little) endian, the device-specific region is encoded in
+the native endian of the guest (where such distinction is
+applicable).
+
+  Device Initialization Sequence
+
+We start with an overview of device initialization, then expand
+on the details of the device and how each step is preformed.
+
+  Reset the device. This is not required on initial start up.
+
+  The ACKNOWLEDGE status bit is set: we have noticed the device.
+
+  The DRIVER status bit is set: we know how to drive the device.
+
+  Device-specific setup, including reading the Device Feature
+  Bits, discovery of virtqueues for the device, optional MSI-X
+  setup, and reading and possibly writing the virtio
+  configuration space.
+
+  The subset of Device Feature Bits understood by the driver is
+  written to the device.
+
+  The DRIVER_OK status bit is set.
+
+  The device can now be used (ie. buffers added to the
+  virtqueues)[footnote:
+Historically, drivers have used the device before steps 5 and 6.
+This is only allowed if the driver does not use any features
+which would alter this early use of the device.
+]
+
+If any of these steps go irrecoverably wrong, the guest should
+set the FAILED status bit to indicate that it has given up on the
+device (it can reset the device later to restart if desired).
+
+We now cover the fields required for general setup in detail.
+
+  Virtio Header
+
+The virtio header looks as follows:
+
+
++------------++---------------------+---------------------+----------+--------+---------+---------+---------+--------+
+| Bits       || 32                  | 32                  | 32       | 16     | 16      | 16      | 8       | 8      |
++------------++---------------------+---------------------+----------+--------+---------+---------+---------+--------+
+| Read/Write || R                   | R+W                 | R+W      | R      | R+W     | R+W     | R+W     | R      |
++------------++---------------------+---------------------+----------+--------+---------+---------+---------+--------+
+| Purpose    || Device              | Guest               | Queue    | Queue  | Queue   | Queue   | Device  | ISR    |
+|            || Features bits 0:31  | Features bits 0:31  | Address  | Size   | Select  | Notify  | Status  | Status |
++------------++---------------------+---------------------+----------+--------+---------+---------+---------+--------+
+
+
+If MSI-X is enabled for the device, two additional fields
+immediately follow this header:
+
+
++------------++----------------+--------+
+| Bits       || 16             | 16     |
+              +----------------+--------+
++------------++----------------+--------+
+| Read/Write || R+W            | R+W    |
++------------++----------------+--------+
+| Purpose    || Configuration  | Queue  |
+| (MSI-X)    || Vector         | Vector |
++------------++----------------+--------+
+
+
+Finally, if feature bits (VIRTIO_F_FEATURES_HI) this is
+immediately followed by two additional fields:
+
+
++------------++----------------------+----------------------
+| Bits       || 32                   | 32
++------------++----------------------+----------------------
+| Read/Write || R                    | R+W
++------------++----------------------+----------------------
+| Purpose    || Device               | Guest
+|            || Features bits 32:63  | Features bits 32:63
++------------++----------------------+----------------------
+
+
+Immediately following these general headers, there may be
+device-specific headers:
+
+
++------------++--------------------+
+| Bits       || Device Specific    |
+              +--------------------+
++------------++--------------------+
+| Read/Write || Device Specific    |
++------------++--------------------+
+| Purpose    || Device Specific... |
+|            ||                    |
++------------++--------------------+
+
+
+  Device Status
+
+The Device Status field is updated by the guest to indicate its
+progress. This provides a simple low-level diagnostic: it's most
+useful to imagine them hooked up to traffic lights on the console
+indicating the status of each device.
+
+The device can be reset by writing a 0 to this field, otherwise
+at least one bit should be set:
+
+  ACKNOWLEDGE (1) Indicates that the guest OS has found the
+  device and recognized it as a valid virtio device.
+
+  DRIVER (2) Indicates that the guest OS knows how to drive the
+  device. Under Linux, drivers can be loadable modules so there
+  may be a significant (or infinite) delay before setting this
+  bit.
+
+  DRIVER_OK (3) Indicates that the driver is set up and ready to
+  drive the device.
+
+  FAILED (8) Indicates that something went wrong in the guest,
+  and it has given up on the device. This could be an internal
+  error, or the driver didn't like the device for some reason, or
+  even a fatal error during device operation. The device must be
+  reset before attempting to re-initialize.
+
+  Feature Bits
+
+The least significant 31 bits of the first configuration field
+indicates the features that the device supports (the high bit is
+reserved, and will be used to indicate the presence of future
+feature bits elsewhere). If more than 31 feature bits are
+supported, the device indicates so by setting feature bit 31 (see
+[cha:Reserved-Feature-Bits]). The bits are allocated as follows:
+
+  0 to 23 Feature bits for the specific device type
+
+  24 to 40 Feature bits reserved for extensions to the queue and
+  feature negotiation mechanisms
+
+  41 to 63 Feature bits reserved for future extensions
+
+For example, feature bit 0 for a network device (i.e. Subsystem
+Device ID 1) indicates that the device supports checksumming of
+packets.
+
+The feature bits are negotiated: the device lists all the
+features it understands in the Device Features field, and the
+guest writes the subset that it understands into the Guest
+Features field. The only way to renegotiate is to reset the
+device.
+
+In particular, new fields in the device configuration header are
+indicated by offering a feature bit, so the guest can check
+before accessing that part of the configuration space.
+
+This allows for forwards and backwards compatibility: if the
+device is enhanced with a new feature bit, older guests will not
+write that feature bit back to the Guest Features field and it
+can go into backwards compatibility mode. Similarly, if a guest
+is enhanced with a feature that the device doesn't support, it
+will not see that feature bit in the Device Features field and
+can go into backwards compatibility mode (or, for poor
+implementations, set the FAILED Device Status bit).
+
+Access to feature bits 32 to 63 is enabled by Guest by setting
+feature bit 31. If this bit is unset, Device must assume that all
+feature bits > 31 are unset.
+
+  Configuration/Queue Vectors
+
+When MSI-X capability is present and enabled in the device
+(through standard PCI configuration space) 4 bytes at byte offset
+20 are used to map configuration change and queue interrupts to
+MSI-X vectors. In this case, the ISR Status field is unused, and
+device specific configuration starts at byte offset 24 in virtio
+header structure. When MSI-X capability is not enabled, device
+specific configuration starts at byte offset 20 in virtio header.
+
+Writing a valid MSI-X Table entry number, 0 to 0x7FF, to one of
+Configuration/Queue Vector registers, maps interrupts triggered
+by the configuration change/selected queue events respectively to
+the corresponding MSI-X vector. To disable interrupts for a
+specific event type, unmap it by writing a special NO_VECTOR
+value:
+
+/* Vector value used to disable MSI for queue */
+
+#define VIRTIO_MSI_NO_VECTOR            0xffff
+
+Reading these registers returns vector mapped to a given event,
+or NO_VECTOR if unmapped. All queue and configuration change
+events are unmapped by default.
+
+Note that mapping an event to vector might require allocating
+internal device resources, and might fail. Devices report such
+failures by returning the NO_VECTOR value when the relevant
+Vector field is read. After mapping an event to vector, the
+driver must verify success by reading the Vector field value: on
+success, the previously written value is returned, and on
+failure, NO_VECTOR is returned. If a mapping failure is detected,
+the driver can retry mapping with fewervectors, or disable MSI-X.
+
+  Virtqueue Configuration
+
+As a device can have zero or more virtqueues for bulk data
+transport (for example, the network driver has two), the driver
+needs to configure them as part of the device-specific
+configuration.
+
+This is done as follows, for each virtqueue a device has:
+
+  Write the virtqueue index (first queue is 0) to the Queue
+  Select field.
+
+  Read the virtqueue size from the Queue Size field, which is
+  always a power of 2. This controls how big the virtqueue is
+  (see below). If this field is 0, the virtqueue does not exist.
+
+  Allocate and zero virtqueue in contiguous physical memory, on a
+  4096 byte alignment. Write the physical address, divided by
+  4096 to the Queue Address field.[footnote:
+The 4096 is based on the x86 page size, but it's also large
+enough to ensure that the separate parts of the virtqueue are on
+separate cache lines.
+]
+
+  Optionally, if MSI-X capability is present and enabled on the
+  device, select a vector to use to request interrupts triggered
+  by virtqueue events. Write the MSI-X Table entry number
+  corresponding to this vector in Queue Vector field. Read the
+  Queue Vector field: on success, previously written value is
+  returned; on failure, NO_VECTOR value is returned.
+
+The Queue Size field controls the total number of bytes required
+for the virtqueue according to the following formula:
+
+#define ALIGN(x) (((x) + 4095) & ~4095)
+
+static inline unsigned vring_size(unsigned int qsz)
+
+{
+
+     return ALIGN(sizeof(struct vring_desc)*qsz + sizeof(u16)*(2
++ qsz))
+
+          + ALIGN(sizeof(struct vring_used_elem)*qsz);
+
+}
+
+This currently wastes some space with padding, but also allows
+future extensions. The virtqueue layout structure looks like this
+(qsz is the Queue Size field, which is a variable, so this code
+won't compile):
+
+struct vring {
+
+    /* The actual descriptors (16 bytes each) */
+
+    struct vring_desc desc[qsz];
+
+
+
+    /* A ring of available descriptor heads with free-running
+index. */
+
+    struct vring_avail avail;
+
+
+
+    // Padding to the next 4096 boundary.
+
+    char pad[];
+
+
+
+    // A ring of used descriptor heads with free-running index.
+
+    struct vring_used used;
+
+};
+
+  A Note on Virtqueue Endianness
+
+Note that the endian of these fields and everything else in the
+virtqueue is the native endian of the guest, not little-endian as
+PCI normally is. This makes for simpler guest code, and it is
+assumed that the host already has to be deeply aware of the guest
+endian so such an “endian-aware� device is not a significant
+issue.
+
+  Descriptor Table
+
+The descriptor table refers to the buffers the guest is using for
+the device. The addresses are physical addresses, and the buffers
+can be chained via the next field. Each descriptor describes a
+buffer which is read-only or write-only, but a chain of
+descriptors can contain both read-only and write-only buffers.
+
+No descriptor chain may be more than 2^32 bytes long in total.struct vring_desc {
+
+    /* Address (guest-physical). */
+
+    u64 addr;
+
+    /* Length. */
+
+    u32 len;
+
+/* This marks a buffer as continuing via the next field. */
+
+#define VRING_DESC_F_NEXT   1
+
+/* This marks a buffer as write-only (otherwise read-only). */
+
+#define VRING_DESC_F_WRITE     2
+
+/* This means the buffer contains a list of buffer descriptors.
+*/
+
+#define VRING_DESC_F_INDIRECT   4
+
+    /* The flags as indicated above. */
+
+    u16 flags;
+
+    /* Next field if flags & NEXT */
+
+    u16 next;
+
+};
+
+The number of descriptors in the table is specified by the Queue
+Size field for this virtqueue.
+
+  <sub:Indirect-Descriptors>Indirect Descriptors
+
+Some devices benefit by concurrently dispatching a large number
+of large requests. The VIRTIO_RING_F_INDIRECT_DESC feature can be
+used to allow this (see [cha:Reserved-Feature-Bits]). To increase
+ring capacity it is possible to store a table of indirect
+descriptors anywhere in memory, and insert a descriptor in main
+virtqueue (with flags&INDIRECT on) that refers to memory buffer
+containing this indirect descriptor table; fields addr and len
+refer to the indirect table address and length in bytes,
+respectively. The indirect table layout structure looks like this
+(len is the length of the descriptor that refers to this table,
+which is a variable, so this code won't compile):
+
+struct indirect_descriptor_table {
+
+    /* The actual descriptors (16 bytes each) */
+
+    struct vring_desc desc[len / 16];
+
+};
+
+The first indirect descriptor is located at start of the indirect
+descriptor table (index 0), additional indirect descriptors are
+chained by next field. An indirect descriptor without next field
+(with flags&NEXT off) signals the end of the indirect descriptor
+table, and transfers control back to the main virtqueue. An
+indirect descriptor can not refer to another indirect descriptor
+table (flags&INDIRECT must be off). A single indirect descriptor
+table can include both read-only and write-only descriptors;
+write-only flag (flags&WRITE) in the descriptor that refers to it
+is ignored.
+
+  Available Ring
+
+The available ring refers to what descriptors we are offering the
+device: it refers to the head of a descriptor chain. The “flags�
+field is currently 0 or 1: 1 indicating that we do not need an
+interrupt when the device consumes a descriptor from the
+available ring. Alternatively, the guest can ask the device to
+delay interrupts until an entry with an index specified by the “
+used_event� field is written in the used ring (equivalently,
+until the idx field in the used ring will reach the value
+used_event + 1). The method employed by the device is controlled
+by the VIRTIO_RING_F_EVENT_IDX feature bit (see [cha:Reserved-Feature-Bits]
+). This interrupt suppression is merely an optimization; it may
+not suppress interrupts entirely.
+
+The “idx� field indicates where we would put the next descriptor
+entry (modulo the ring size). This starts at 0, and increases.
+
+struct vring_avail {
+
+#define VRING_AVAIL_F_NO_INTERRUPT      1
+
+   u16 flags;
+
+   u16 idx;
+
+   u16 ring[qsz]; /* qsz is the Queue Size field read from device
+*/
+
+   u16 used_event;
+
+};
+
+  Used Ring
+
+The used ring is where the device returns buffers once it is done
+with them. The flags field can be used by the device to hint that
+no notification is necessary when the guest adds to the available
+ring. Alternatively, the “avail_event� field can be used by the
+device to hint that no notification is necessary until an entry
+with an index specified by the “avail_event� is written in the
+available ring (equivalently, until the idx field in the
+available ring will reach the value avail_event + 1). The method
+employed by the device is controlled by the guest through the
+VIRTIO_RING_F_EVENT_IDX feature bit (see [cha:Reserved-Feature-Bits]
+). [footnote:
+These fields are kept here because this is the only part of the
+virtqueue written by the device
+].
+
+Each entry in the ring is a pair: the head entry of the
+descriptor chain describing the buffer (this matches an entry
+placed in the available ring by the guest earlier), and the total
+of bytes written into the buffer. The latter is extremely useful
+for guests using untrusted buffers: if you do not know exactly
+how much has been written by the device, you usually have to zero
+the buffer to ensure no data leakage occurs.
+
+/* u32 is used here for ids for padding reasons. */
+
+struct vring_used_elem {
+
+    /* Index of start of used descriptor chain. */
+
+    u32 id;
+
+    /* Total length of the descriptor chain which was used
+(written to) */
+
+    u32 len;
+
+};
+
+
+
+struct vring_used {
+
+#define VRING_USED_F_NO_NOTIFY  1
+
+    u16 flags;
+
+    u16 idx;
+
+    struct vring_used_elem ring[qsz];
+
+    u16 avail_event;
+
+};
+
+  Helpers for Managing Virtqueues
+
+The Linux Kernel Source code contains the definitions above and
+helper routines in a more usable form, in
+include/linux/virtio_ring.h. This was explicitly licensed by IBM
+and Red Hat under the (3-clause) BSD license so that it can be
+freely used by all other projects, and is reproduced (with slight
+variation to remove Linux assumptions) in Appendix A.
+
+  Device Operation
+
+There are two parts to device operation: supplying new buffers to
+the device, and processing used buffers from the device. As an
+example, the virtio network device has two virtqueues: the
+transmit virtqueue and the receive virtqueue. The driver adds
+outgoing (read-only) packets to the transmit virtqueue, and then
+frees them after they are used. Similarly, incoming (write-only)
+buffers are added to the receive virtqueue, and processed after
+they are used.
+
+  Supplying Buffers to The Device
+
+Actual transfer of buffers from the guest OS to the device
+operates as follows:
+
+  Place the buffer(s) into free descriptor(s).
+
+  If there are no free descriptors, the guest may choose to
+    notify the device even if notifications are suppressed (to
+    reduce latency).[footnote:
+The Linux drivers do this only for read-only buffers: for
+write-only buffers, it is assumed that the driver is merely
+trying to keep the receive buffer ring full, and no notification
+of this expected condition is necessary.
+]
+
+  Place the id of the buffer in the next ring entry of the
+  available ring.
+
+  The steps (1) and (2) may be performed repeatedly if batching
+  is possible.
+
+  A memory barrier should be executed to ensure the device sees
+  the updated descriptor table and available ring before the next
+  step.
+
+  The available “idx� field should be increased by the number of
+  entries added to the available ring.
+
+  A memory barrier should be executed to ensure that we update
+  the idx field before checking for notification suppression.
+
+  If notifications are not suppressed, the device should be
+  notified of the new buffers.
+
+Note that the above code does not take precautions against the
+available ring buffer wrapping around: this is not possible since
+the ring buffer is the same size as the descriptor table, so step
+(1) will prevent such a condition.
+
+In addition, the maximum queue size is 32768 (it must be a power
+of 2 which fits in 16 bits), so the 16-bit “idx� value can always
+distinguish between a full and empty buffer.
+
+Here is a description of each stage in more detail.
+
+  Placing Buffers Into The Descriptor Table
+
+A buffer consists of zero or more read-only physically-contiguous
+elements followed by zero or more physically-contiguous
+write-only elements (it must have at least one element). This
+algorithm maps it into the descriptor table:
+
+  for each buffer element, b:
+
+  Get the next free descriptor table entry, d
+
+  Set d.addr to the physical address of the start of b
+
+  Set d.len to the length of b.
+
+  If b is write-only, set d.flags to VRING_DESC_F_WRITE,
+    otherwise 0.
+
+  If there is a buffer element after this:
+
+    Set d.next to the index of the next free descriptor element.
+
+    Set the VRING_DESC_F_NEXT bit in d.flags.
+
+In practice, the d.next fields are usually used to chain free
+descriptors, and a separate count kept to check there are enough
+free descriptors before beginning the mappings.
+
+  Updating The Available Ring
+
+The head of the buffer we mapped is the first d in the algorithm
+above. A naive implementation would do the following:
+
+avail->ring[avail->idx % qsz] = head;
+
+However, in general we can add many descriptors before we update
+the “idx� field (at which point they become visible to the
+device), so we keep a counter of how many we've added:
+
+avail->ring[(avail->idx + added++) % qsz] = head;
+
+  Updating The Index Field
+
+Once the idx field of the virtqueue is updated, the device will
+be able to access the descriptor entries we've created and the
+memory they refer to. This is why a memory barrier is generally
+used before the idx update, to ensure it sees the most up-to-date
+copy.
+
+The idx field always increments, and we let it wrap naturally at
+65536:
+
+avail->idx += added;
+
+  <sub:Notifying-The-Device>Notifying The Device
+
+Device notification occurs by writing the 16-bit virtqueue index
+of this virtqueue to the Queue Notify field of the virtio header
+in the first I/O region of the PCI device. This can be expensive,
+however, so the device can suppress such notifications if it
+doesn't need them. We have to be careful to expose the new idx
+value before checking the suppression flag: it's OK to notify
+gratuitously, but not to omit a required notification. So again,
+we use a memory barrier here before reading the flags or the
+avail_event field.
+
+If the VIRTIO_F_RING_EVENT_IDX feature is not negotiated, and if
+the VRING_USED_F_NOTIFY flag is not set, we go ahead and write to
+the PCI configuration space.
+
+If the VIRTIO_F_RING_EVENT_IDX feature is negotiated, we read the
+avail_event field in the available ring structure. If the
+available index crossed_the avail_event field value since the
+last notification, we go ahead and write to the PCI configuration
+space. The avail_event field wraps naturally at 65536 as well:
+
+(u16)(new_idx - avail_event - 1) < (u16)(new_idx - old_idx)
+
+  <sub:Receiving-Used-Buffers>Receiving Used Buffers From The

+Once the device has used a buffer (read from or written to it, or
+parts of both, depending on the nature of the virtqueue and the
+device), it sends an interrupt, following an algorithm very
+similar to the algorithm used for the driver to send the device a
+buffer:
+
+  Write the head descriptor number to the next field in the used
+  ring.
+
+  Update the used ring idx.
+
+  Determine whether an interrupt is necessary:
+
+  If the VIRTIO_F_RING_EVENT_IDX feature is not negotiated: check
+    if f the VRING_AVAIL_F_NO_INTERRUPT flag is not set in avail-
+    >flags
+
+  If the VIRTIO_F_RING_EVENT_IDX feature is negotiated: check
+    whether the used index crossed the used_event field value
+    since the last update. The used_event field wraps naturally
+    at 65536 as well:(u16)(new_idx - used_event - 1) < (u16)(new_idx - old_idx)
+
+  If an interrupt is necessary:
+
+  If MSI-X capability is disabled:
+
+    Set the lower bit of the ISR Status field for the device.
+
+    Send the appropriate PCI interrupt for the device.
+
+  If MSI-X capability is enabled:
+
+    Request the appropriate MSI-X interrupt message for the
+      device, Queue Vector field sets the MSI-X Table entry
+      number.
+
+    If Queue Vector field value is NO_VECTOR, no interrupt
+      message is requested for this event.
+
+The guest interrupt handler should:
+
+  If MSI-X capability is disabled: read the ISR Status field,
+  which will reset it to zero. If the lower bit is zero, the
+  interrupt was not for this device. Otherwise, the guest driver
+  should look through the used rings of each virtqueue for the
+  device, to see if any progress has been made by the device
+  which requires servicing.
+
+  If MSI-X capability is enabled: look through the used rings of
+  each virtqueue mapped to the specific MSI-X vector for the
+  device, to see if any progress has been made by the device
+  which requires servicing.
+
+For each ring, guest should then disable interrupts by writing
+VRING_AVAIL_F_NO_INTERRUPT flag in avail structure, if required.
+It can then process used ring entries finally enabling interrupts
+by clearing the VRING_AVAIL_F_NO_INTERRUPT flag or updating the
+EVENT_IDX field in the available structure, Guest should then
+execute a memory barrier, and then recheck the ring empty
+condition. This is necessary to handle the case where, after the
+last check and before enabling interrupts, an interrupt has been
+suppressed by the device:
+
+vring_disable_interrupts(vq);
+
+for (;;) {
+
+    if (vq->last_seen_used != vring->used.idx) {
+
+		vring_enable_interrupts(vq);
+
+		mb();
+
+		if (vq->last_seen_used != vring->used.idx)
+
+			break;
+
+    }
+
+    struct vring_used_elem *e =
+vring.used->ring[vq->last_seen_used%vsz];
+
+    process_buffer(e);
+
+    vq->last_seen_used++;
+
+}
+
+  Dealing With Configuration Changes
+
+Some virtio PCI devices can change the device configuration
+state, as reflected in the virtio header in the PCI configuration
+space. In this case:
+
+  If MSI-X capability is disabled: an interrupt is delivered and
+  the second highest bit is set in the ISR Status field to
+  indicate that the driver should re-examine the configuration
+  space.Note that a single interrupt can indicate both that one
+  or more virtqueue has been used and that the configuration
+  space has changed: even if the config bit is set, virtqueues
+  must be scanned.
+
+  If MSI-X capability is enabled: an interrupt message is
+  requested. The Configuration Vector field sets the MSI-X Table
+  entry number to use. If Configuration Vector field value is
+  NO_VECTOR, no interrupt message is requested for this event.
+
+Creating New Device Types
+
+Various considerations are necessary when creating a new device
+type:
+
+  How Many Virtqueues?
+
+It is possible that a very simple device will operate entirely
+through its configuration space, but most will need at least one
+virtqueue in which it will place requests. A device with both
+input and output (eg. console and network devices described here)
+need two queues: one which the driver fills with buffers to
+receive input, and one which the driver places buffers to
+transmit output.
+
+  What Configuration Space Layout?
+
+Configuration space is generally used for rarely-changing or
+initialization-time parameters. But it is a limited resource, so
+it might be better to use a virtqueue to update configuration
+information (the network device does this for filtering,
+otherwise the table in the config space could potentially be very
+large).
+
+Note that this space is generally the guest's native endian,
+rather than PCI's little-endian.
+
+  What Device Number?
+
+Currently device numbers are assigned quite freely: a simple
+request mail to the author of this document or the Linux
+virtualization mailing list[footnote:
+
+https://lists.linux-foundation.org/mailman/listinfo/virtualization
+] will be sufficient to secure a unique one.
+
+Meanwhile for experimental drivers, use 65535 and work backwards.
+
+  How many MSI-X vectors?
+
+Using the optional MSI-X capability devices can speed up
+interrupt processing by removing the need to read ISR Status
+register by guest driver (which might be an expensive operation),
+reducing interrupt sharing between devices and queues within the
+device, and handling interrupts from multiple CPUs. However, some
+systems impose a limit (which might be as low as 256) on the
+total number of MSI-X vectors that can be allocated to all
+devices. Devices and/or device drivers should take this into
+account, limiting the number of vectors used unless the device is
+expected to cause a high volume of interrupts. Devices can
+control the number of vectors used by limiting the MSI-X Table
+Size or not presenting MSI-X capability in PCI configuration
+space. Drivers can control this by mapping events to as small
+number of vectors as possible, or disabling MSI-X capability
+altogether.
+
+  Message Framing
+
+The descriptors used for a buffer should not effect the semantics
+of the message, except for the total length of the buffer. For
+example, a network buffer consists of a 10 byte header followed
+by the network packet. Whether this is presented in the ring
+descriptor chain as (say) a 10 byte buffer and a 1514 byte
+buffer, or a single 1524 byte buffer, or even three buffers,
+should have no effect.
+
+In particular, no implementation should use the descriptor
+boundaries to determine the size of any header in a request.[footnote:
+The current qemu device implementations mistakenly insist that
+the first descriptor cover the header in these cases exactly, so
+a cautious driver should arrange it so.
+]
+
+  Device Improvements
+
+Any change to configuration space, or new virtqueues, or
+behavioural changes, should be indicated by negotiation of a new
+feature bit. This establishes clarity[footnote:
+Even if it does mean documenting design or implementation
+mistakes!
+] and avoids future expansion problems.
+
+Clusters of functionality which are always implemented together
+can use a single bit, but if one feature makes sense without the
+others they should not be gratuitously grouped together to
+conserve feature bits. We can always extend the spec when the
+first person needs more than 24 feature bits for their device.

+
+<cha:Reserved-Feature-Bits>Appendix B: Reserved Feature Bits
+
+Currently there are five device-independent feature bits defined:
+
+  VIRTIO_F_NOTIFY_ON_EMPTY (24) Negotiating this feature
+  indicates that the driver wants an interrupt if the device runs
+  out of available descriptors on a virtqueue, even though
+  interrupts are suppressed using the VRING_AVAIL_F_NO_INTERRUPT
+  flag or the used_event field. An example of this is the
+  networking driver: it doesn't need to know every time a packet
+  is transmitted, but it does need to free the transmitted
+  packets a finite time after they are transmitted. It can avoid
+  using a timer if the device interrupts it when all the packets
+  are transmitted.
+
+  VIRTIO_F_RING_INDIRECT_DESC (28) Negotiating this feature
+  indicates that the driver can use descriptors with the
+  VRING_DESC_F_INDIRECT flag set, as described in [sub:Indirect-Descriptors]
+  .
+
+  VIRTIO_F_RING_EVENT_IDX(29) This feature enables the used_event
+  and the avail_event fields. If set, it indicates that the
+  device should ignore the flags field in the available ring
+  structure. Instead, the used_event field in this structure is
+  used by guest to suppress device interrupts. Further, the
+  driver should ignore the flags field in the used ring
+  structure. Instead, the avail_event field in this structure is
+  used by the device to suppress notifications. If unset, the
+  driver should ignore the used_event field; the device should
+  ignore the avail_event field; the flags field is used
+
+  VIRTIO_F_BAD_FEATURE(30) This feature should never be
+  negotiated by the guest; doing so is an indication that the
+  guest is faulty[footnote:
+An experimental virtio PCI driver contained in Linux version
+2.6.25 had this problem, and this feature bit can be used to
+detect it.
+]
+
+  VIRTIO_F_FEATURES_HIGH(31) This feature indicates that the
+  device supports feature bits 32:63. If unset, feature bits
+  32:63 are unset.
+
+Appendix C: Network Device
+
+The virtio network device is a virtual ethernet card, and is the
+most complex of the devices supported so far by virtio. It has
+enhanced rapidly and demonstrates clearly how support for new
+features should be added to an existing device. Empty buffers are
+placed in one virtqueue for receiving packets, and outgoing
+packets are enqueued into another for transmission in that order.
+A third command queue is used to control advanced filtering
+features.

+    any GSO type.[footnote:
+It was supposed to indicate segmentation offload support, but
+upon further investigation it became clear that multiple bits
+were required.
+]
+
+  VIRTIO_NET_F_GUEST_TSO4 (7) Guest can receive TSOv4.
+
+  VIRTIO_NET_F_GUEST_TSO6 (8) Guest can receive TSOv6.
+
+  VIRTIO_NET_F_GUEST_ECN (9) Guest can receive TSO with ECN.
+

+

+
+  VIRTIO_NET_F_HOST_ECN (13) Device can receive TSO with ECN.
+
+  VIRTIO_NET_F_HOST_UFO (14) Device can receive UFO.
+
+  VIRTIO_NET_F_MRG_RXBUF (15) Guest can merge receive buffers.
+
+  VIRTIO_NET_F_STATUS (16) Configuration status field is
+    available.
+
+  VIRTIO_NET_F_CTRL_VQ (17) Control channel is available.
+
+  VIRTIO_NET_F_CTRL_RX (18) Control channel RX mode support.
+
+  VIRTIO_NET_F_CTRL_VLAN (19) Control channel VLAN filtering.
+
+  Device configuration layout Two configuration fields are
+  currently defined. The mac address field always exists (though
+  is only valid if VIRTIO_NET_F_MAC is set), and the status field
+  only exists if VIRTIO_NET_F_STATUS is set. Only one bit is
+  currently defined for the status field: VIRTIO_NET_S_LINK_UP. #define VIRTIO_NET_S_LINK_UP	1
+
+
+
+struct virtio_net_config {
+
+    u8 mac[6];
+
+    u16 status;
+
+};
+
+  Device Initialization
+
+  The initialization routine should identify the receive and
+  transmission virtqueues.
+
+  If the VIRTIO_NET_F_MAC feature bit is set, the configuration
+  space “mac� entry indicates the “physical� address of the the
+  network card, otherwise a private MAC address should be
+  assigned. All guests are expected to negotiate this feature if
+  it is set.
+
+  If the VIRTIO_NET_F_CTRL_VQ feature bit is negotiated, identify
+  the control virtqueue.
+
+  If the VIRTIO_NET_F_STATUS feature bit is negotiated, the link
+  status can be read from the bottom bit of the “status� config
+  field. Otherwise, the link should be assumed active.
+
+  The receive virtqueue should be filled with receive buffers.
+  This is described in detail below in “Setting Up Receive
+  Buffers�.
+
+  A driver can indicate that it will generate checksumless
+  packets by negotating the VIRTIO_NET_F_CSUM feature. This “
+  checksum offload� is a common feature on modern network cards.
+
+  If that feature is negotiated, a driver can use TCP or UDP
+  segmentation offload by negotiating the VIRTIO_NET_F_HOST_TSO4
+  (IPv4 TCP), VIRTIO_NET_F_HOST_TSO6 (IPv6 TCP) and
+  VIRTIO_NET_F_HOST_UFO (UDP fragmentation) features. It should
+  not send TCP packets requiring segmentation offload which have
+  the Explicit Congestion Notification bit set, unless the
+  VIRTIO_NET_F_HOST_ECN feature is negotiated.[footnote:
+This is a common restriction in real, older network cards.
+]
+
+  The converse features are also available: a driver can save the
+  virtual device some work by negotiating these features.[footnote:
+For example, a network packet transported between two guests on
+the same system may not require checksumming at all, nor
+segmentation, if both guests are amenable.
+] The VIRTIO_NET_F_GUEST_CSUM feature indicates that partially
+  checksummed packets can be received, and if it can do that then
+  the VIRTIO_NET_F_GUEST_TSO4, VIRTIO_NET_F_GUEST_TSO6,
+  VIRTIO_NET_F_GUEST_UFO and VIRTIO_NET_F_GUEST_ECN are the input
+  equivalents of the features described above. See “Receiving
+  Packets� below.
+
+  Device Operation
+
+Packets are transmitted by placing them in the transmitq, and
+buffers for incoming packets are placed in the receiveq. In each
+case, the packet itself is preceeded by a header:
+
+struct virtio_net_hdr {
+
+#define VIRTIO_NET_HDR_F_NEEDS_CSUM    1
+
+	u8 flags;
+
+#define VIRTIO_NET_HDR_GSO_NONE        0
+
+#define VIRTIO_NET_HDR_GSO_TCPV4       1
+
+#define VIRTIO_NET_HDR_GSO_UDP		 3
+
+#define VIRTIO_NET_HDR_GSO_TCPV6       4
+
+#define VIRTIO_NET_HDR_GSO_ECN      0x80
+
+	u8 gso_type;
+
+	u16 hdr_len;
+
+	u16 gso_size;
+
+	u16 csum_start;
+
+	u16 csum_offset;
+
+/* Only if VIRTIO_NET_F_MRG_RXBUF: */
+
+	u16 num_buffers
+
+};
+
+The controlq is used to control device features such as
+filtering.
+
+  Packet Transmission
+
+Transmitting a single packet is simple, but varies depending on
+the different features the driver negotiated.
+
+  If the driver negotiated VIRTIO_NET_F_CSUM, and the packet has
+  not been fully checksummed, then the virtio_net_hdr's fields
+  are set as follows. Otherwise, the packet must be fully
+  checksummed, and flags is zero.
+
+  flags has the VIRTIO_NET_HDR_F_NEEDS_CSUM set,
+
+  <ite:csum_start-is-set>csum_start is set to the offset within
+    the packet to begin checksumming, and
+
+  csum_offset indicates how many bytes after the csum_start the
+    new (16 bit ones' complement) checksum should be placed.[footnote:
+For example, consider a partially checksummed TCP (IPv4) packet.
+It will have a 14 byte ethernet header and 20 byte IP header
+followed by the TCP header (with the TCP checksum field 16 bytes
+into that header). csum_start will be 14+20 = 34 (the TCP
+checksum includes the header), and csum_offset will be 16. The
+value in the TCP checksum field will be the sum of the TCP pseudo
+header, so that replacing it by the ones' complement checksum of
+the TCP header and body will give the correct result.
+]
+
+  <enu:If-the-driver>If the driver negotiated
+  VIRTIO_NET_F_HOST_TSO4, TSO6 or UFO, and the packet requires
+  TCP segmentation or UDP fragmentation, then the “gso_type�
+  field is set to VIRTIO_NET_HDR_GSO_TCPV4, TCPV6 or UDP.
+  (Otherwise, it is set to VIRTIO_NET_HDR_GSO_NONE). In this
+  case, packets larger than 1514 bytes can be transmitted: the
+  metadata indicates how to replicate the packet header to cut it
+  into smaller packets. The other gso fields are set:
+
+  hdr_len is a hint to the device as to how much of the header
+    needs to be kept to copy into each packet, usually set to the
+    length of the headers, including the transport header.[footnote:
+Due to various bugs in implementations, this field is not useful
+as a guarantee of the transport header size.
+]
+
+  gso_size is the size of the packet beyond that header (ie.
+    MSS).
+
+  If the driver negotiated the VIRTIO_NET_F_HOST_ECN feature, the
+    VIRTIO_NET_HDR_GSO_ECN bit may be set in “gso_type� as well,
+    indicating that the TCP packet has the ECN bit set.[footnote:
+This case is not handled by some older hardware, so is called out
+specifically in the protocol.
+]
+
+  If the driver negotiated the VIRTIO_NET_F_MRG_RXBUF feature,
+  the num_buffers field is set to zero.
+
+  The header and packet are added as one output buffer to the
+  transmitq, and the device is notified of the new entry (see [sub:Notifying-The-Device]
+  ).[footnote:
+Note that the header will be two bytes longer for the
+VIRTIO_NET_F_MRG_RXBUF case.
+]
+
+  Packet Transmission Interrupt
+
+Often a driver will suppress transmission interrupts using the
+VRING_AVAIL_F_NO_INTERRUPT flag (see [sub:Receiving-Used-Buffers]
+) and check for used packets in the transmit path of following
+packets. However, it will still receive interrupts if the
+VIRTIO_F_NOTIFY_ON_EMPTY feature is negotiated, indicating that
+the transmission queue is completely emptied.
+
+The normal behavior in this interrupt handler is to retrieve and
+new descriptors from the used ring and free the corresponding
+headers and packets.
+
+  Setting Up Receive Buffers
+
+It is generally a good idea to keep the receive virtqueue as
+fully populated as possible: if it runs out, network performance
+will suffer.
+
+If the VIRTIO_NET_F_GUEST_TSO4, VIRTIO_NET_F_GUEST_TSO6 or
+VIRTIO_NET_F_GUEST_UFO features are used, the Guest will need to
+accept packets of up to 65550 bytes long (the maximum size of a
+TCP or UDP packet, plus the 14 byte ethernet header), otherwise
+1514 bytes. So unless VIRTIO_NET_F_MRG_RXBUF is negotiated, every
+buffer in the receive queue needs to be at least this length [footnote:
+Obviously each one can be split across multiple descriptor
+elements.
+].
+
+If VIRTIO_NET_F_MRG_RXBUF is negotiated, each buffer must be at
+least the size of the struct virtio_net_hdr.
+
+  Packet Receive Interrupt
+
+When a packet is copied into a buffer in the receiveq, the
+optimal path is to disable further interrupts for the receiveq
+(see [sub:Receiving-Used-Buffers]) and process packets until no
+more are found, then re-enable them.
+
+Processing packet involves:
+
+  If the driver negotiated the VIRTIO_NET_F_MRG_RXBUF feature,
+  then the “num_buffers� field indicates how many descriptors
+  this packet is spread over (including this one). This allows
+  receipt of large packets without having to allocate large
+  buffers. In this case, there will be at least “num_buffers� in
+  the used ring, and they should be chained together to form a
+  single packet. The other buffers will not begin with a struct
+  virtio_net_hdr.
+
+  If the VIRTIO_NET_F_MRG_RXBUF feature was not negotiated, or
+  the “num_buffers� field is one, then the entire packet will be
+  contained within this buffer, immediately following the struct
+  virtio_net_hdr.
+
+  If the VIRTIO_NET_F_GUEST_CSUM feature was negotiated, the
+  VIRTIO_NET_HDR_F_NEEDS_CSUM bit in the “flags� field may be
+  set: if so, the checksum on the packet is incomplete and the “
+  csum_start� and “csum_offset� fields indicate how to calculate
+  it (see [ite:csum_start-is-set]).
+
+  If the VIRTIO_NET_F_GUEST_TSO4, TSO6 or UFO options were
+  negotiated, then the “gso_type� may be something other than
+  VIRTIO_NET_HDR_GSO_NONE, and the “gso_size� field indicates the
+  desired MSS (see [enu:If-the-driver]).Control Virtqueue
+
+The driver uses the control virtqueue (if VIRTIO_NET_F_VTRL_VQ is
+negotiated) to send commands to manipulate various features of
+the device which would not easily map into the configuration
+space.
+
+All commands are of the following form:
+
+struct virtio_net_ctrl {
+
+	u8 class;
+
+	u8 command;
+
+	u8 command-specific-data[];
+
+	u8 ack;
+
+};
+
+
+
+/* ack values */
+
+#define VIRTIO_NET_OK     0
+
+#define VIRTIO_NET_ERR    1
+
+The class, command and command-specific-data are set by the
+driver, and the device sets the ack byte. There is little it can
+do except issue a diagnostic if the ack byte is not
+VIRTIO_NET_OK.
+
+  Packet Receive Filtering
+
+If the VIRTIO_NET_F_CTRL_RX feature is negotiated, the driver can
+send control commands for promiscuous mode, multicast receiving,
+and filtering of MAC addresses.
+
+Note that in general, these commands are best-effort: unwanted
+packets may still arrive.
+
+  Setting Promiscuous Mode
+
+#define VIRTIO_NET_CTRL_RX    0
+
+ #define VIRTIO_NET_CTRL_RX_PROMISC      0
+
+ #define VIRTIO_NET_CTRL_RX_ALLMULTI     1
+
+The class VIRTIO_NET_CTRL_RX has two commands:
+VIRTIO_NET_CTRL_RX_PROMISC turns promiscuous mode on and off, and
+VIRTIO_NET_CTRL_RX_ALLMULTI turns all-multicast receive on and
+off. The command-specific-data is one byte containing 0 (off) or
+1 (on).
+
+  Setting MAC Address Filtering
+
+struct virtio_net_ctrl_mac {
+
+	u32 entries;
+
+	u8 macs[entries][ETH_ALEN];
+
+};
+
+
+
+#define VIRTIO_NET_CTRL_MAC    1
+
+ #define VIRTIO_NET_CTRL_MAC_TABLE_SET        0
+
+The device can filter incoming packets by any number of
+destination MAC addresses.[footnote:
+Since there are no guarentees, it can use a hash filter
+orsilently switch to allmulti or promiscuous mode if it is given
+too many addresses.
+] This table is set using the class VIRTIO_NET_CTRL_MAC and the
+command VIRTIO_NET_CTRL_MAC_TABLE_SET. The command-specific-data
+is two variable length tables of 6-byte MAC addresses. The first
+table contains unicast addresses, and the second contains
+multicast addresses.
+
+  VLAN Filtering
+
+If the driver negotiates the VIRTION_NET_F_CTRL_VLAN feature, it
+can control a VLAN filter table in the device.
+
+#define VIRTIO_NET_CTRL_VLAN       2
+
+ #define VIRTIO_NET_CTRL_VLAN_ADD             0
+
+ #define VIRTIO_NET_CTRL_VLAN_DEL             1
+
+Both the VIRTIO_NET_CTRL_VLAN_ADD and VIRTIO_NET_CTRL_VLAN_DEL
+command take a 16-bit VLAN id as the command-specific-data.
+
+Appendix D: Block Device
+
+The virtio block device is a simple virtual block device (ie.
+disk). Read and write requests (and other exotic requests) are
+placed in the queue, and serviced (probably out of order) by the
+device except where noted.
+
+  Configuration
+
+  Subsystem Device ID 2
+
+  Virtqueues 0:requestq.
+
+  Feature bits
+
+  VIRTIO_BLK_F_BARRIER (0) Host supports request barriers.
+
+  VIRTIO_BLK_F_SIZE_MAX (1) Maximum size of any single segment is
+    in “size_max�.
+
+  VIRTIO_BLK_F_SEG_MAX (2) Maximum number of segments in a
+    request is in “seg_max�.
+
+  VIRTIO_BLK_F_GEOMETRY (4) Disk-style geometry specified in “
+    geometry�.
+
+  VIRTIO_BLK_F_RO (5) Device is read-only.
+
+  VIRTIO_BLK_F_BLK_SIZE (6) Block size of disk is in “blk_size�.
+
+  VIRTIO_BLK_F_SCSI (7) Device supports scsi packet commands.
+
+  VIRTIO_BLK_F_FLUSH (9) Cache flush command support.
+
+
+
+  Device configuration layout The capacity of the device
+  (expressed in 512-byte sectors) is always present. The
+  availability of the others all depend on various feature bits
+  as indicated above. struct virtio_blk_config {
+
+	u64 capacity;
+
+	u32 size_max;
+
+	u32 seg_max;
+
+	struct virtio_blk_geometry {
+
+		u16 cylinders;
+
+		u8 heads;
+
+		u8 sectors;
+
+	} geometry;
+
+	u32 blk_size;
+
+
+
+};
+
+  Device Initialization
+
+  The device size should be read from the “capacity�
+  configuration field. No requests should be submitted which goes
+  beyond this limit.
+
+  If the VIRTIO_BLK_F_BLK_SIZE feature is negotiated, the
+  blk_size field can be read to determine the optimal sector size
+  for the driver to use. This does not effect the units used in
+  the protocol (always 512 bytes), but awareness of the correct
+  value can effect performance.
+
+  If the VIRTIO_BLK_F_RO feature is set by the device, any write
+  requests will fail.
+
+
+
+  Device Operation
+
+The driver queues requests to the virtqueue, and they are used by
+the device (not necessarily in order). Each request is of form:
+
+struct virtio_blk_req {
+
+
+
+	u32 type;
+
+	u32 ioprio;
+
+	u64 sector;
+
+	char data[][512];
+
+	u8 status;
+
+};
+
+If the device has VIRTIO_BLK_F_SCSI feature, it can also support
+scsi packet command requests, each of these requests is of form:struct virtio_scsi_pc_req {
+
+	u32 type;
+
+	u32 ioprio;
+
+	u64 sector;
+
+    char cmd[];
+
+	char data[][512];
+
+#define SCSI_SENSE_BUFFERSIZE   96
+
+    u8 sense[SCSI_SENSE_BUFFERSIZE];
+
+    u32 errors;
+
+    u32 data_len;
+
+    u32 sense_len;
+
+    u32 residual;
+
+	u8 status;
+
+};
+
+The type of the request is either a read (VIRTIO_BLK_T_IN), a
+write (VIRTIO_BLK_T_OUT), a scsi packet command
+(VIRTIO_BLK_T_SCSI_CMD or VIRTIO_BLK_T_SCSI_CMD_OUT[footnote:
+the SCSI_CMD and SCSI_CMD_OUT types are equivalent, the device
+does not distinguish between them
+]) or a flush (VIRTIO_BLK_T_FLUSH or VIRTIO_BLK_T_FLUSH_OUT[footnote:
+the FLUSH and FLUSH_OUT types are equivalent, the device does not
+distinguish between them
+]). If the device has VIRTIO_BLK_F_BARRIER feature the high bit
+(VIRTIO_BLK_T_BARRIER) indicates that this request acts as a
+barrier and that all preceeding requests must be complete before
+this one, and all following requests must not be started until
+this is complete. Note that a barrier does not flush caches in
+the underlying backend device in host, and thus does not serve as
+data consistency guarantee. Driver must use FLUSH request to
+flush the host cache.
+
+#define VIRTIO_BLK_T_IN           0
+
+#define VIRTIO_BLK_T_OUT          1
+
+#define VIRTIO_BLK_T_SCSI_CMD     2
+
+#define VIRTIO_BLK_T_SCSI_CMD_OUT 3
+
+#define VIRTIO_BLK_T_FLUSH        4
+
+#define VIRTIO_BLK_T_FLUSH_OUT    5
+
+#define VIRTIO_BLK_T_BARRIER	 0x80000000
+
+The ioprio field is a hint about the relative priorities of
+requests to the device: higher numbers indicate more important
+requests.
+
+The sector number indicates the offset (multiplied by 512) where
+the read or write is to occur. This field is unused and set to 0
+for scsi packet commands and for flush commands.
+
+The cmd field is only present for scsi packet command requests,
+and indicates the command to perform. This field must reside in a
+single, separate read-only buffer; command length can be derived
+from the length of this buffer.
+
+Note that these first three (four for scsi packet commands)
+fields are always read-only: the data field is either read-only
+or write-only, depending on the request. The size of the read or
+write can be derived from the total size of the request buffers.
+
+The sense field is only present for scsi packet command requests,
+and indicates the buffer for scsi sense data.
+
+The data_len field is only present for scsi packet command
+requests, this field is deprecated, and should be ignored by the
+driver. Historically, devices copied data length there.
+
+The sense_len field is only present for scsi packet command
+requests and indicates the number of bytes actually written to
+the sense buffer.
+
+The residual field is only present for scsi packet command
+requests and indicates the residual size, calculated as data
+length - number of bytes actually transferred.
+
+The final status byte is written by the device: either
+VIRTIO_BLK_S_OK for success, VIRTIO_BLK_S_IOERR for host or guest
+error or VIRTIO_BLK_S_UNSUPP for a request unsupported by host:#define VIRTIO_BLK_S_OK        0
+
+#define VIRTIO_BLK_S_IOERR     1
+
+#define VIRTIO_BLK_S_UNSUPP    2
+
+Historically, devices assumed that the fields type, ioprio and
+sector reside in a single, separate read-only buffer; the fields
+errors, data_len, sense_len and residual reside in a single,
+separate write-only buffer; the sense field in a separate
+write-only buffer of size 96 bytes, by itself; the fields errors,
+data_len, sense_len and residual in a single write-only buffer;
+and the status field is a separate read-only buffer of size 1
+byte, by itself.
+
+Appendix E: Console Device
+
+The virtio console device is a simple device for data input and
+output. A device may have one or more ports. Each port has a pair
+of input and output virtqueues. Moreover, a device has a pair of
+control IO virtqueues. The control virtqueues are used to
+communicate information between the device and the driver about
+ports being opened and closed on either side of the connection,
+indication from the host about whether a particular port is a
+console port, adding new ports, port hot-plug/unplug, etc., and
+indication from the guest about whether a port or a device was
+successfully added, port open/close, etc.. For data IO, one or
+more empty buffers are placed in the receive queue for incoming
+data and outgoing characters are placed in the transmit queue.
+
+  Configuration
+
+  Subsystem Device ID 3
+
+  Virtqueues 0:receiveq(port0). 1:transmitq(port0), 2:control
+  receiveq[footnote:
+Ports 2 onwards only if VIRTIO_CONSOLE_F_MULTIPORT is set
+], 3:control transmitq, 4:receiveq(port1), 5:transmitq(port1),
+  ...
+
+  Feature bits
+
+  VIRTIO_CONSOLE_F_SIZE (0) Configuration cols and rows fields
+    are valid.
+
+  VIRTIO_CONSOLE_F_MULTIPORT(1) Device has support for multiple
+    ports; configuration fields nr_ports and max_nr_ports are
+    valid and control virtqueues will be used.
+
+  Device configuration layout The size of the console is supplied
+  in the configuration space if the VIRTIO_CONSOLE_F_SIZE feature
+  is set. Furthermore, if the VIRTIO_CONSOLE_F_MULTIPORT feature
+  is set, the maximum number of ports supported by the device can
+  be fetched.struct virtio_console_config {
+
+	u16 cols;
+
+	u16 rows;
+
+
+
+	u32 max_nr_ports;
+
+};
+
+  Device Initialization
+
+  If the VIRTIO_CONSOLE_F_SIZE feature is negotiated, the driver
+  can read the console dimensions from the configuration fields.
+
+  If the VIRTIO_CONSOLE_F_MULTIPORT feature is negotiated, the
+  driver can spawn multiple ports, not all of which may be
+  attached to a console. Some could be generic ports. In this
+  case, the control virtqueues are enabled and according to the
+  max_nr_ports configuration-space value, the appropriate number
+  of virtqueues are created. A control message indicating the
+  driver is ready is sent to the host. The host can then send
+  control messages for adding new ports to the device. After
+  creating and initializing each port, a
+  VIRTIO_CONSOLE_PORT_READY control message is sent to the host
+  for that port so the host can let us know of any additional
+  configuration options set for that port.
+
+  The receiveq for each port is populated with one or more
+  receive buffers.
+
+  Device Operation
+
+  For output, a buffer containing the characters is placed in the
+  port's transmitq.[footnote:
+Because this is high importance and low bandwidth, the current
+Linux implementation polls for the buffer to be used, rather than
+waiting for an interrupt, simplifying the implementation
+significantly. However, for generic serial ports with the
+O_NONBLOCK flag set, the polling limitation is relaxed and the
+consumed buffers are freed upon the next write or poll call or
+when a port is closed or hot-unplugged.
+]
+
+  When a buffer is used in the receiveq (signalled by an
+  interrupt), the contents is the input to the port associated
+  with the virtqueue for which the notification was received.
+
+  If the driver negotiated the VIRTIO_CONSOLE_F_SIZE feature, a
+  configuration change interrupt may occur. The updated size can
+  be read from the configuration fields.
+
+  If the driver negotiated the VIRTIO_CONSOLE_F_MULTIPORT
+  feature, active ports are announced by the host using the
+  VIRTIO_CONSOLE_PORT_ADD control message. The same message is
+  used for port hot-plug as well.
+
+  If the host specified a port `name', a sysfs attribute is
+  created with the name filled in, so that udev rules can be
+  written that can create a symlink from the port's name to the
+  char device for port discovery by applications in the guest.
+
+  Changes to ports' state are effected by control messages.
+  Appropriate action is taken on the port indicated in the
+  control message. The layout of the structure of the control
+  buffer and the events associated are:struct virtio_console_control {
+
+	uint32_t id;    /* Port number */
+
+	uint16_t event; /* The kind of control event */
+
+	uint16_t value; /* Extra information for the event */

+
+Appendix G: Memory Balloon Device
+
+The virtio memory balloon device is a primitive device for
+managing guest memory: the device asks for a certain amount of
+memory, and the guest supplies it (or withdraws it, if the device
+has more than it asks for). This allows the guest to adapt to
+changes in allowance of underlying physical memory. If the
+feature is negotiated, the device can also be used to communicate
+guest memory statistics to the host.
+
+  Configuration
+
+  Subsystem Device ID 5
+
+  Virtqueues 0:inflateq. 1:deflateq. 2:statsq.[footnote:

+    pages from the balloon are used.
+
+  VIRTIO_BALLOON_F_STATS_VQ (1) A virtqueue for reporting guest
+    memory statistics is present.
+
+  Device configuration layout Both fields of this configuration
+  are always available. Note that they are little endian, despite
+  convention that device fields are guest endian:struct virtio_balloon_config {
+
+	u32 num_pages;
+
+	u32 actual;
+
+};
+
+  Device Initialization
+
+  The inflate and deflate virtqueues are identified.
+
+  If the VIRTIO_BALLOON_F_STATS_VQ feature bit is negotiated:
+
+  Identify the stats virtqueue.
+
+  Add one empty buffer to the stats virtqueue and notify the
+    host.
+
+Device operation begins immediately.
+
+  Device Operation
+
+  Memory Ballooning The device is driven by the receipt of a
+  configuration change interrupt.
+
+  The “num_pages� configuration field is examined. If this is
+  greater than the “actual� number of pages, memory must be given
+  to the balloon. If it is less than the “actual� number of
+  pages, memory may be taken back from the balloon for general
+  use.
+
+  To supply memory to the balloon (aka. inflate):
+
+  The driver constructs an array of addresses of unused memory
+    pages. These addresses are divided by 4096[footnote:
+This is historical, and independent of the guest page size
+] and the descriptor describing the resulting 32-bit array is
+    added to the inflateq.
+
+  To remove memory from the balloon (aka. deflate):
+
+  The driver constructs an array of addresses of memory pages it
+    has previously given to the balloon, as described above. This
+    descriptor is added to the deflateq.
+
+  If the VIRTIO_BALLOON_F_MUST_TELL_HOST feature is set, the
+    guest may not use these requested pages until that descriptor
+    in the deflateq has been used by the device.
+
+  Otherwise, the guest may begin to re-use pages previously given
+    to the balloon before the device has acknowledged their
+    withdrawl. [footnote:
+In this case, deflation advice is merely a courtesy
+]
+
+  In either case, once the device has completed the inflation or
+  deflation, the “actual� field of the configuration should be
+  updated to reflect the new number of pages in the balloon.[footnote:
+As updates to configuration space are not atomic, this field
+isn't particularly reliable, but can be used to diagnose buggy
+guests.
+]
+
+  Memory Statistics
+
+The stats virtqueue is atypical because communication is driven
+by the device (not the driver). The channel becomes active at
+driver initialization time when the driver adds an empty buffer
+and notifies the device. A request for memory statistics proceeds
+as follows:
+
+  The device pushes the buffer onto the used ring and sends an
+  interrupt.
+
+  The driver pops the used buffer and discards it.
+
+  The driver collects memory statistics and writes them into a
+  new buffer.
+
+  The driver adds the buffer to the virtqueue and notifies the
+  device.
+
+  The device pops the buffer (retaining it to initiate a
+  subsequent request) and consumes the statistics.
+
+  Memory Statistics Format Each statistic consists of a 16 bit
+  tag and a 64 bit value. Both quantities are represented in the
+  native endian of the guest. All statistics are optional and the
+  driver may choose which ones to supply. To guarantee backwards
+  compatibility, unsupported statistics should be omitted.

+ * Hardware-wise, we have a two level page table structure, where the first
+ * level has 4096 entries, and the second level has 256 entries.  Each entry
+ * is one 32-bit word.  Most of the bits in the second level entry are used
+ * by hardware, and there aren't any "accessed" and "dirty" bits.
+ *
+ * Linux on the other hand has a three level page table structure, which can
+ * be wrapped to fit a two level page table structure easily - using the PGD
+ * and PTE only.  However, Linux also expects one "PTE" table per page, and
+ * at least a "dirty" bit.
+ *
+ * Therefore, we tweak the implementation slightly - we tell Linux that we
+ * have 2048 entries in the first level, each of which is 8 bytes (iow, two
+ * hardware pointers to the second level.)  The second level contains two
+ * hardware PTE tables arranged contiguously, preceded by Linux versions
+ * which contain the state information Linux needs.  We, therefore, end up
+ * with 512 entries in the "PTE" level.
+ *
+ * This leads to the page tables having the following layout:
+ *
+ *    pgd             pte
+ * |        |

+ * +--------+ +8    |  h/w pt 1  |

+ *
+ * See L_PTE_xxx below for definitions of bits in the "Linux pt", and
+ * PTE_xxx for definitions of bits appearing in the "h/w pt".
+ *
+ * PMD_xxx definitions refer to bits in the first level page table.
+ *
+ * The "dirty" bit is emulated by only granting hardware write permission
+ * iff the page is marked "writable" and "dirty" in the Linux PTE.  This
+ * means that a write to a clean page will cause a permission fault, and
+ * the Linux MM layer will mark the page dirty via handle_pte_fault().
+ * For the hardware to notice the permission change, the TLB entry must
+ * be flushed, and ptep_set_access_flags() does that for us.
+ *
+ * The "accessed" or "young" bit is emulated by a similar method; we only

+ * PTE entry.  Again, ptep_set_access_flags() will ensure that the TLB is
+ * up to date.
+ *
+ * However, when the "young" bit is cleared, we deny access to the page
+ * by clearing the hardware PTE.  Currently Linux does not flush the TLB

-##      The bootrom copies data from the NAND flash to the internal RAM but
-##      due to a bug/feature we can only trust the 256 first bytes. So this
-##      code copies more data from NAND flash to internal RAM. Obvioulsy this
-##      code must fit in the first 256 bytes so alter with care.
-##
-##	Some notes about the bug/feature for future reference:
-##        The bootrom copies the first 127 KB from NAND flash to internal
-##        memory. The problem is that it does a bytewise copy. NAND flashes
-##        does autoincrement on the address so for a 16-bite device each
-##        read/write increases the address by two. So the copy loop in the
-##        bootrom will discard every second byte. This is solved by inserting
-##        zeroes in every second byte in the first erase block.
-##
-##        The bootrom also incorrectly assumes that it can read the flash
-##        linear with only one read command but the flash will actually
-##        switch between normal area and spare area if you do that so we
-##        can't trust more than the first 256 bytes.

-	  If you anticipate running this kernel on a computer with a MC68030

-config M68KFPU_EMU
-	bool "Math emulation support (EXPERIMENTAL)"
-	depends on EXPERIMENTAL
-	help
-	  At some point in the future, this will cause floating-point math
-	  instructions to be emulated by the kernel on machines that lack a
-	  floating-point math coprocessor.  Thrill-seekers and chronically
-	  sleep-deprived psychotic hacker types can say Y now, everyone else
-	  should probably wait a while.
-
-config M68KFPU_EMU_EXTRAPREC
-	bool "Math emulation extra precision"
-	depends on M68KFPU_EMU
-	help
-	  The fpu uses normally a few bit more during calculations for
-	  correct rounding, the emulator can (often) do the same but this
-	  extra calculation can cost quite some time, so you can disable
-	  it here. The emulator will then "only" calculate with a 64 bit
-	  mantissa and round slightly incorrect, what is more than enough
-	  for normal usage.
-
-config M68KFPU_EMU_ONLY
-	bool "Math emulation only kernel"
-	depends on M68KFPU_EMU
-	help
-	  This option prevents any floating-point instructions from being
-	  compiled into the kernel, thereby the kernel doesn't save any
-	  floating point context anymore during task switches, so this
-	  kernel will only be usable on machines without a floating-point
-	  math coprocessor. This makes the kernel a bit faster as no tests
-	  needs to be executed whether a floating-point instruction in the
-	  kernel should be executed or not.
-
-config ADVANCED
-	bool "Advanced configuration options"
-	---help---
-	  This gives you access to some advanced options for the CPU. The
-	  defaults should be fine for most users, but these options may make
-	  it possible for you to improve performance somewhat if you know what
-	  you are doing.
-
-	  Note that the answer to this question won't directly affect the
-	  kernel: saying N will just cause the configurator to skip all
-	  the questions about these options.
-
-	  Most users should say N to this question.
-
-config RMW_INSNS
-	bool "Use read-modify-write instructions"
-	depends on ADVANCED
-	---help---
-	  This allows to use certain instructions that work with indivisible
-	  read-modify-write bus cycles. While this is faster than the
-	  workaround of disabling interrupts, it can conflict with DMA
-	  ( = direct memory access) on many Amiga systems, and it is also said
-	  to destabilize other machines. It is very likely that this will
-	  cause serious problems on any Amiga or Atari Medusa if set. The only
-	  configuration where it should work are 68030-based Ataris, where it
-	  apparently improves performance. But you've been warned! Unless you
-	  really know what you are doing, say N. Try Y only if you're quite
-	  adventurous.
-
-config SINGLE_MEMORY_CHUNK
-	bool "Use one physical chunk of memory only" if ADVANCED && !SUN3
-	default y if SUN3
-	select NEED_MULTIPLE_NODES
-	help
-	  Ignore all but the first contiguous chunk of physical memory for VM
-	  purposes.  This will save a few bytes kernel size and may speed up
-	  some operations.  Say N if not sure.
-
-config 060_WRITETHROUGH
-	bool "Use write-through caching for 68060 supervisor accesses"
-	depends on ADVANCED && M68060
-	---help---
-	  The 68060 generally uses copyback caching of recently accessed data.
-	  Copyback caching means that memory writes will be held in an on-chip
-	  cache and only written back to memory some time later.  Saying Y
-	  here will force supervisor (kernel) accesses to use writethrough
-	  caching.  Writethrough caching means that data is written to memory
-	  straight away, so that cache and memory data always agree.
-	  Writethrough caching is less efficient, but is needed for some
-	  drivers on 68060 based systems where the 68060 bus snooping signal
-	  is hardwired on.  The 53c710 SCSI driver is known to suffer from
-	  this problem.

-	depends on AMIGA
-	help
-	  This enables support for the Zorro bus in the Amiga. If you have
-	  expansion cards in your Amiga that conform to the Amiga
-	  AutoConfig(tm) specification, say Y, otherwise N. Note that even
-	  expansion cards that do not fit in the Zorro slots but fit in e.g.
-	  the CPU slot may fall in this category, so you have to say Y to let
-	  Linux use these.
-
-config AMIGA_PCMCIA
-	bool "Amiga 1200/600 PCMCIA support (EXPERIMENTAL)"
-	depends on AMIGA && EXPERIMENTAL
-	help
-	  Include support in the kernel for pcmcia on Amiga 1200 and Amiga
-	  600. If you intend to use pcmcia cards say Y; otherwise say N.

-	bool "Use power LED as a heartbeat" if AMIGA || APOLLO || ATARI || MAC ||Q40
-	default y if !AMIGA && !APOLLO && !ATARI && !MAC && !Q40 && HP300
-	help
-	  Use the power-on LED on your machine as a load meter.  The exact
-	  behavior is platform-dependent, but normally the flash frequency is
-	  a hyperbolic function of the 5-minute load average.
-
-# We have a dedicated heartbeat LED. :-)
-config PROC_HARDWARE
-	bool "/proc/hardware support"
-	help
-	  Say Y here to support the /proc/hardware file, which gives you
-	  access to information about the machine you're running on,
-	  including the model, CPU, MMU, clock speed, BogoMIPS rating,
-	  and memory size.
-
-config ISA

-	help
-	  Find out whether you have ISA slots on your motherboard.  ISA is the
-	  name of a bus system, i.e. the way the CPU talks to the other stuff
-	  inside your box.  Other bus systems are PCI, EISA, MicroChannel
-	  (MCA) or VESA.  ISA is an older system, now being displaced by PCI;

+ * This QoS design is best effort based. Dependents register their QoS needs.
+ * Watchers register to keep track of the current QoS needs of the system.
+ * Watchers can register different types of notification callbacks:
+ *  . a per-device notification callback using the dev_pm_qos_*_notifier API.
+ *    The notification chain data is stored in the per-device constraint
+ *    data struct.
+ *  . a system-wide notification callback using the dev_pm_qos_*_global_notifier
+ *    API. The notification chain data is stored in a static variable.
+ *
+ * Note about the per-device constraint data struct allocation:
+ * . The per-device constraints data struct ptr is tored into the device
+ *    dev_pm_info.
+ * . To minimize the data usage by the per-device constraints, the data struct
+ *   is only allocated at the first call to dev_pm_qos_add_request.
+ * . The data is later free'd when the device is removed from the system.
+ *  . A global mutex protects the constraints users from the data being

- * needed after a SCC access anyway. Additionally, _SCCwrite() manages
- * writes to WR0 and WR8 differently, because these can be accessed
- * directly with less overhead. Another special case are WR7 and WR7'.
- * _SCCwrite automatically checks what of this registers is selected
- * and changes b0 of WR15 if needed.
- * 
- * _SCCread() for standard read registers is straightforward, except
- * for RR2 (split into two "virtual" registers: one for the value
- * written to WR2 (from the shadow) and one for the vector including
- * status from RR2, Ch. B) and RR3. The latter must be read from
- * Channel A, because it reads as all zeros on Ch. B. RR0 and RR8 can
- * be accessed directly as before.
- * 
- * The two inline function contain complicated switch statements. But
- * I rely on regno and final_delay being constants, so gcc can reduce
- * the whole stuff to just some assembler statements.
- * 
- * _SCCwrite and _SCCread aren't intended to be used directly under
- * normal circumstances. The macros SCCread[_ND] and SCCwrite[_ND] are
- * for that purpose. They assume that a local variable 'port' is
- * declared and pointing to the port's scc_struct entry. The
- * variants with "_NB" appended should be used if no other SCC
- * accesses follow immediately (within 0.5 usecs). They just skip the
- * final delay nops.
- * 
- * Please note that accesses to SCC registers should only take place
- * when interrupts are turned off (at least if SCC interrupts are
- * enabled). Otherwise, an interrupt could interfere with the
- * two-stage accessing process.

+	  governor provided to DEVFREQ choose an operating frequency
+	  based on the OPP's list and the policy given with DEVFREQ.
+

+	  disabled or enabled).
+
+	  Like some CPUs with CPUFREQ, a device may have multiple clocks.
+	  However, because the clock frequencies of a single device are

+	  is attached to a single device and returns a "representative"
+	  clock frequency from the OPP of the device, which is also attached

-	  RELCOM line fill and keepalive monitoring. Ideal on poor quality
-	  analogue lines.
-
-config SLIP_MODE_SLIP6
-	bool "Six bit SLIP encapsulation"
-	depends on SLIP
-	help
-	  Just occasionally you may need to run IP over hostile serial
-	  networks that don't pass all control characters or are only seven
-	  bit. Saying Y here adds an extra mode you can use with SLIP:
-	  "slip6". In this mode, SLIP will only send normal ASCII symbols over
-	  the serial device. Naturally, this has to be supported at the other
-	  end of the link as well. It's good enough, for example, to run IP
-	  over the async ports of a Camtec JNT Pad. If unsure, say N.
-
-config NET_FC
-	bool "Fibre Channel driver support"
-	depends on SCSI && PCI
-	help
-	  Fibre Channel is a high speed serial protocol mainly used to connect
-	  large storage devices to the computer; it is compatible with and
-	  intended to replace SCSI.
-
-	  If you intend to use Fibre Channel, you need to have a Fibre channel
-	  adaptor card in your computer; say Y here and to the driver for your
-	  adaptor below. You also should have said Y to "SCSI support" and
-	  "SCSI generic support".
-
-config NETCONSOLE
-	tristate "Network console logging support"
-	---help---
-	If you want to log kernel messages over the network, enable this.
-	See <file:Documentation/networking/netconsole.txt> for details.
-
-config NETCONSOLE_DYNAMIC
-	bool "Dynamic reconfiguration of logging targets"
-	depends on NETCONSOLE && SYSFS && CONFIGFS_FS && \
-			!(NETCONSOLE=y && CONFIGFS_FS=m)
-	help
-	  This option enables the ability to dynamically reconfigure target
-	  parameters (interface, IP addresses, port numbers, MAC addresses)
-	  at runtime through a userspace interface exported using configfs.
-	  See <file:Documentation/networking/netconsole.txt> for details.

+config FDDI
+	tristate "FDDI driver support"
+	depends on PCI || EISA || TC
+	---help---
+	  Fiber Distributed Data Interface is a high speed local area network
+	  design; essentially a replacement for high speed Ethernet. FDDI can
+	  run over copper or fiber. If you are connected to such a network and
+	  want a driver for the FDDI card in your computer, say Y here (and
+	  then also Y to the driver for your FDDI card, below). Most people
+	  will say N.
+
+if FDDI
+
+config DEFXX
+	tristate "Digital DEFTA/DEFEA/DEFPA adapter support"
+	depends on FDDI && (PCI || EISA || TC)
+	---help---
+	  This is support for the DIGITAL series of TURBOchannel (DEFTA),
+	  EISA (DEFEA) and PCI (DEFPA) controllers which can connect you
+	  to a local FDDI network.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called defxx.  If unsure, say N.
+
+config DEFXX_MMIO
+	bool
+	prompt "Use MMIO instead of PIO" if PCI || EISA
+	depends on DEFXX
+	default n if PCI || EISA
+	default y
+	---help---
+	  This instructs the driver to use EISA or PCI memory-mapped I/O
+	  (MMIO) as appropriate instead of programmed I/O ports (PIO).
+	  Enabling this gives an improvement in processing time in parts
+	  of the driver, but it may cause problems with EISA (DEFEA)
+	  adapters.  TURBOchannel does not have the concept of I/O ports,
+	  so MMIO is always used for these (DEFTA) adapters.
+
+	  If unsure, say N.
+
+config SKFP
+	tristate "SysKonnect FDDI PCI support"
+	depends on FDDI && PCI
+	select BITREVERSE
+	---help---
+	  Say Y here if you have a SysKonnect FDDI PCI adapter.
+	  The following adapters are supported by this driver:
+	  - SK-5521 (SK-NET FDDI-UP)
+	  - SK-5522 (SK-NET FDDI-UP DAS)
+	  - SK-5541 (SK-NET FDDI-FP)
+	  - SK-5543 (SK-NET FDDI-LP)
+	  - SK-5544 (SK-NET FDDI-LP DAS)
+	  - SK-5821 (SK-NET FDDI-UP64)
+	  - SK-5822 (SK-NET FDDI-UP64 DAS)
+	  - SK-5841 (SK-NET FDDI-FP64)
+	  - SK-5843 (SK-NET FDDI-LP64)
+	  - SK-5844 (SK-NET FDDI-LP64 DAS)
+	  - Netelligent 100 FDDI DAS Fibre SC
+	  - Netelligent 100 FDDI SAS Fibre SC
+	  - Netelligent 100 FDDI DAS UTP
+	  - Netelligent 100 FDDI SAS UTP
+	  - Netelligent 100 FDDI SAS Fibre MIC
+
+	  Read <file:Documentation/networking/skfp.txt> for information about
+	  the driver.
+
+	  Questions concerning this driver can be addressed to:
+	  <linux@syskonnect.de>
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called skfp.  This is recommended.

+	  HIgh Performance Parallel Interface (HIPPI) is a 800Mbit/sec and
+	  1600Mbit/sec dual-simplex switched or point-to-point network. HIPPI
+	  can run over copper (25m) or fiber (300m on multi-mode or 10km on
+	  single-mode). HIPPI networks are commonly used for clusters and to
+	  connect to super computers. If you are connected to a HIPPI network
+	  and have a HIPPI network card in your computer that you want to use
+	  under Linux, say Y here (you must also remember to enable the driver
+	  for your HIPPI card below). Most people will say N here.

+	  of additional memory to allow for fastest operation, both for
+	  transmitting and receiving. This memory cannot be used by any other
+	  kernel code or by user space programs. Say Y here only if you have
+	  the memory.

------------------------------------------------------------------------------
-
-				Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the RealTek RTL8139 series, the RealTek
-Fast Ethernet controllers for PCI and CardBus.  This chip is used on many
-low-end boards, sometimes with its markings changed.
-
-
-II. Board-specific settings
-
-PCI bus devices are configured by the system at boot time, so no jumpers
-need to be set on the board.  The system BIOS will assign the
-PCI INTA signal to a (preferably otherwise unused) system IRQ line.
-
-III. Driver operation
-
-IIIa. Rx Ring buffers
-
-The receive unit uses a single linear ring buffer rather than the more
-common (and more efficient) descriptor-based architecture.  Incoming frames
-are sequentially stored into the Rx region, and the host copies them into
-skbuffs.
-
-Comment: While it is theoretically possible to process many frames in place,
-any delay in Rx processing would cause us to drop frames.  More importantly,
-the Linux protocol stack is not designed to operate in this manner.
-
-IIIb. Tx operation
-
-The RTL8139 uses a fixed set of four Tx descriptors in register space.
-In a stunningly bad design choice, Tx frames must be 32 bit aligned.  Linux
-aligns the IP header on word boundaries, and 14 byte ethernet header means
-that almost all frames will need to be copied to an alignment buffer.

+config PLIP
+	tristate "PLIP (parallel port) support"
+	depends on PARPORT
+	---help---
+	  PLIP (Parallel Line Internet Protocol) is used to create a
+	  reasonably fast mini network consisting of two (or, rarely, more)
+	  local machines.  A PLIP link from a Linux box is a popular means to
+	  install a Linux distribution on a machine which doesn't have a
+	  CD-ROM drive (a minimal system has to be transferred with floppies
+	  first). The kernels on both machines need to have this PLIP option
+	  enabled for this to work.
+
+	  The PLIP driver has two modes, mode 0 and mode 1.  The parallel
+	  ports (the connectors at the computers with 25 holes) are connected
+	  with "null printer" or "Turbo Laplink" cables which can transmit 4
+	  bits at a time (mode 0) or with special PLIP cables, to be used on
+	  bidirectional parallel ports only, which can transmit 8 bits at a
+	  time (mode 1); you can find the wiring of these cables in
+	  <file:Documentation/networking/PLIP.txt>.  The cables can be up to
+	  15m long.  Mode 0 works also if one of the machines runs DOS/Windows
+	  and has some PLIP software installed, e.g. the Crynwr PLIP packet
+	  driver (<http://oak.oakland.edu/simtel.net/msdos/pktdrvr-pre.html>)
+	  and winsock or NCSA's telnet.
+
+	  If you want to use PLIP, say Y and read the PLIP mini-HOWTO as well
+	  as the NET-3-HOWTO, both available from
+	  <http://www.tldp.org/docs.html#howto>.  Note that the PLIP
+	  protocol has been changed and this PLIP driver won't work together
+	  with the PLIP support in Linux versions 1.0.x.  This option enlarges
+	  your kernel by about 8 KB.
+
+	  To compile this driver as a module, choose M here. The module
+	  will be called plip. If unsure, say Y or M, in case you buy
+	  a laptop later.

+config PPP
+	tristate "PPP (point-to-point protocol) support"
+	select SLHC
+	---help---
+	  PPP (Point to Point Protocol) is a newer and better SLIP.  It serves
+	  the same purpose: sending Internet traffic over telephone (and other
+	  serial) lines.  Ask your access provider if they support it, because
+	  otherwise you can't use it; most Internet access providers these
+	  days support PPP rather than SLIP.
+
+	  To use PPP, you need an additional program called pppd as described
+	  in the PPP-HOWTO, available at
+	  <http://www.tldp.org/docs.html#howto>.  Make sure that you have
+	  the version of pppd recommended in <file:Documentation/Changes>.
+	  The PPP option enlarges your kernel by about 16 KB.
+
+	  There are actually two versions of PPP: the traditional PPP for
+	  asynchronous lines, such as regular analog phone lines, and
+	  synchronous PPP which can be used over digital ISDN lines for
+	  example.  If you want to use PPP over phone lines or other
+	  asynchronous serial lines, you need to say Y (or M) here and also to
+	  the next option, "PPP support for async serial ports".  For PPP over
+	  synchronous lines, you should say Y (or M) here and to "Support
+	  synchronous PPP", below.
+
+	  If you said Y to "Version information on all symbols" above, then
+	  you cannot compile the PPP driver into the kernel; you can then only
+	  compile it as a module. To compile this driver as a module, choose M
+	  here. The module will be called ppp_generic.

+	  method as well for this to be useful. Even if they don't support it,
+	  it is safe to say Y here.
+
+	  The PPP Deflate compression method ("PPP Deflate compression",
+	  above) is preferable to BSD-Compress, because it compresses better
+	  and is patent-free.
+
+	  Note that the BSD compression code will always be compiled as a

+	 * we know that response data is available.
+	 *
+	 * This allows us to cleanly timeout on an unexpected
+	 * Target failure rather than risk problems at the HIF level.
+	 * In particular, this avoids SDIO timeouts and possibly garbage
+	 * data on some host controllers.  And on an interconnect
+	 * such as Compact Flash (as well as some SDIO masters) which
+	 * does not provide any indication on data timeout, it avoids
+	 * a potential hang or garbage response.
+	 *
+	 * Synchronization is more difficult for reads larger than the
+	 * size of the MBOX FIFO (128B), because the Target is unable
+	 * to push the 129th byte of data until AFTER the Host posts an
+	 * HIF Read and removes some FIFO data.  So for large reads the
+	 * Host proceeds to post an HIF Read BEFORE all the data is
+	 * actually available to read.  Fortunately, large BMI reads do
+	 * not occur in practice -- they're supported for debug/development.
+	 *
+	 * So Host/Target BMI synchronization is divided into these cases:
+	 *  CASE 1: length < 4
+	 *        Should not happen
+	 *
+	 *  CASE 2: 4 <= length <= 128
+	 *        Wait for first 4 bytes to be in FIFO
+	 *        If CONSERVATIVE_BMI_READ is enabled, also wait for
+	 *        a BMI command credit, which indicates that the ENTIRE
+	 *        response is available in the the FIFO
+	 *
+	 *  CASE 3: length > 128
+	 *        Wait for the first 4 bytes to be in FIFO
+	 *
+	 * For most uses, a small timeout should be sufficient and we will
+	 * usually see a response quickly; but there may be some unusual
+	 * (debug) cases of BMI_EXECUTE where we want an larger timeout.
+	 * For now, we use an unbounded busy loop while waiting for
+	 * BMI_EXECUTE.
+	 *
+	 * If BMI_EXECUTE ever needs to support longer-latency execution,
+	 * especially in production, this code needs to be enhanced to sleep

+ * Bootloader Messaging Interface (BMI)
+ *
+ * BMI is a very simple messaging interface used during initialization
+ * to read memory, write memory, execute code, and to define an
+ * application entry PC.
+ *
+ * It is used to download an application to ATH6KL, to provide
+ * patches to code that is already resident on ATH6KL, and generally
+ * to examine and modify state.  The Host has an opportunity to use
+ * BMI only once during bootup.  Once the Host issues a BMI_DONE
+ * command, this opportunity ends.
+ *
+ * The Host writes BMI requests to mailbox0, and reads BMI responses
+ * from mailbox0.   BMI requests all begin with a command
+ * (see below for specific commands), and are followed by
+ * command-specific data.
+ *
+ * Flow control:
+ * The Host can only issue a command once the Target gives it a
+ * "BMI Command Credit", using ATH6KL Counter #4.  As soon as the
+ * Target has completed a command, it issues another BMI Command
+ * Credit (so the Host can issue the next command).
+ *
+ * BMI handles all required Target-side cache flushing.

-From that log10(mag * 2^x) = log2(mag * 2^x) * log10(2) is computed.
-This routine looks the log2 value in the table considering LOG2_LOG_TABLE_SIZE+1 MSBs.
-As the MSB is always 1, only next LOG2_OF_LOG_TABLE_SIZE MSBs are used for table lookup.
-Next 16 MSBs are used for interpolation.
-Inputs:
-N - number to which log10 has to be found.
-qN - q format of N
-log10N - address where log10(N) will be written.
-qLog10N - address where log10N qformat will be written.
-Note/Problem:
-For accurate results input should be in normalized or near normalized form.

+ * The bus layer registers to the bus driver, advertises the supported HW and
+ * gets notifications about enumeration, suspend, resume.
+ * For the moment, the bus layer is not a linux kernel module as itself, and
+ * the module_init function of the driver must call the bus specific

+ * The iwl_bus describes the data that is shared amongst all the bus layer
+ * implementations. This data is visible to other layers. Data in the bus
+ * specific area is not visible outside the bus specific implementation.
+ * iwl_bus holds a pointer to iwl_shared which holds pointer to all the other
+ * layers of the driver (iwl_priv, iwl_trans). In fact, this is the way to go
+ * when the transport layer needs to call a function of another layer.

+ * layer must be here.

+ * NOTE: All the layers hold a pointer to the shared area which must be shrd.
+ *	A few macros assume that (_m)->shrd points to the shared area no matter
+ *	what _m is.
+ *
+ * gets notifications about enumeration, suspend, resume.
+ * For the moment, the bus layer is not a linux kernel module as itself, and

+ * registration functions. These functions are listed at the end of this file.
+ * For the moment, there is only one implementation of this interface: PCI-e.

+ * order to map frames to the right queue, we also need an AC->hw queue
+ * mapping. This is implemented here.
+ *
+ * Due to the way hw queues are set up (by the hw specific modules like

+ * Rx theory of operation
+ *
+ * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
+ * each of which point to Receive Buffers to be filled by the NIC.  These get
+ * used not only for Rx frames, but for any command response or notification
+ * from the NIC.  The driver and NIC manage the Rx buffers by means
+ * of indexes into the circular buffer.
+ *
+ * Rx Queue Indexes
+ * The host/firmware share two index registers for managing the Rx buffers.
+ *
+ * The READ index maps to the first position that the firmware may be writing
+ * to -- the driver can read up to (but not including) this position and get
+ * good data.
+ * The READ index is managed by the firmware once the card is enabled.
+ *
+ * The WRITE index maps to the last position the driver has read from -- the
+ * position preceding WRITE is the last slot the firmware can place a packet.
+ *
+ * The queue is empty (no good data) if WRITE = READ - 1, and is full if
+ * WRITE = READ.
+ *
+ * During initialization, the host sets up the READ queue position to the first
+ * INDEX position, and WRITE to the last (READ - 1 wrapped)
+ *
+ * When the firmware places a packet in a buffer, it will advance the READ index
+ * and fire the RX interrupt.  The driver can then query the READ index and
+ * process as many packets as possible, moving the WRITE index forward as it
+ * resets the Rx queue buffers with new memory.
+ *
+ * The management in the driver is as follows:
+ * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.  When
+ *   iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ *   to replenish the iwl->rxq->rx_free.
+ * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the
+ *   iwl->rxq is replenished and the READ INDEX is updated (updating the
+ *   'processed' and 'read' driver indexes as well)
+ * + A received packet is processed and handed to the kernel network stack,
+ *   detached from the iwl->rxq.  The driver 'processed' index is updated.
+ * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
+ *   list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
+ *   INDEX is not incremented and iwl->status(RX_STALLED) is set.  If there
+ *   were enough free buffers and RX_STALLED is set it is cleared.
+ *
+ *
+ * Driver sequence:
+ *
+ * iwl_rx_queue_alloc()   Allocates rx_free
+ * iwl_rx_replenish()     Replenishes rx_free list from rx_used, and calls
+ *                            iwl_rx_queue_restock
+ * iwl_rx_queue_restock() Moves available buffers from rx_free into Rx
+ *                            queue, updates firmware pointers, and updates
+ *                            the WRITE index.  If insufficient rx_free buffers
+ *                            are available, schedules iwl_rx_replenish
+ *
+ * -- enable interrupts --
+ * ISR - iwl_rx()         Detach iwl_rx_mem_buffers from pool up to the
+ *                            READ INDEX, detaching the SKB from the pool.
+ *                            Moves the packet buffer from queue to rx_used.
+ *                            Calls iwl_rx_queue_restock to refill any empty

- * Rx theory of operation
- *
- * Driver allocates a circular buffer of Receive Buffer Descriptors (RBDs),
- * each of which point to Receive Buffers to be filled by the NIC.  These get
- * used not only for Rx frames, but for any command response or notification
- * from the NIC.  The driver and NIC manage the Rx buffers by means
- * of indexes into the circular buffer.
- *
- * Rx Queue Indexes
- * The host/firmware share two index registers for managing the Rx buffers.
- *
- * The READ index maps to the first position that the firmware may be writing
- * to -- the driver can read up to (but not including) this position and get
- * good data.
- * The READ index is managed by the firmware once the card is enabled.
- *
- * The WRITE index maps to the last position the driver has read from -- the
- * position preceding WRITE is the last slot the firmware can place a packet.
- *
- * The queue is empty (no good data) if WRITE = READ - 1, and is full if
- * WRITE = READ.
- *
- * During initialization, the host sets up the READ queue position to the first
- * INDEX position, and WRITE to the last (READ - 1 wrapped)
- *
- * When the firmware places a packet in a buffer, it will advance the READ index
- * and fire the RX interrupt.  The driver can then query the READ index and
- * process as many packets as possible, moving the WRITE index forward as it
- * resets the Rx queue buffers with new memory.
- *
- * The management in the driver is as follows:
- * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.  When
- *   iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
- *   to replenish the iwl->rxq->rx_free.
- * + In iwl_rx_replenish (scheduled) if 'processed' != 'read' then the
- *   iwl->rxq is replenished and the READ INDEX is updated (updating the
- *   'processed' and 'read' driver indexes as well)
- * + A received packet is processed and handed to the kernel network stack,
- *   detached from the iwl->rxq.  The driver 'processed' index is updated.
- * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free
- *   list. If there are no allocated buffers in iwl->rxq->rx_free, the READ
- *   INDEX is not incremented and iwl->status(RX_STALLED) is set.  If there
- *   were enough free buffers and RX_STALLED is set it is cleared.
- *
- *
- * Driver sequence:
- *
- * iwl_rx_queue_alloc()   Allocates rx_free
- * iwl_rx_replenish()     Replenishes rx_free list from rx_used, and calls
- *                            iwl_rx_queue_restock
- * iwl_rx_queue_restock() Moves available buffers from rx_free into Rx
- *                            queue, updates firmware pointers, and updates
- *                            the WRITE index.  If insufficient rx_free buffers
- *                            are available, schedules iwl_rx_replenish
- *
- * -- enable interrupts --
- * ISR - iwl_rx()         Detach iwl_rx_mem_buffers from pool up to the
- *                            READ INDEX, detaching the SKB from the pool.
- *                            Moves the packet buffer from queue to rx_used.
- *                            Calls iwl_rx_queue_restock to refill any empty
- *                            slots.

-========================
-IWCONFIG COMMANDS
-========================
-power period
-
-	This command is used to configure the station in deep sleep mode /
-	auto deep sleep mode.
-
-	The timer is implemented to monitor the activities (command, event,
-	etc.). When an activity is detected station will exit from deep
-	sleep mode automatically and restart the timer. At timer expiry
-	(no activity for defined time period) the deep sleep mode is entered
-	automatically.
-
-	Note: this command is for SDIO interface only.
-
-	Usage:
-	To enable deep sleep mode do:
-		iwconfig wlan0 power period 0
-	To enable auto deep sleep mode with idle time period 5 seconds do:
-		iwconfig wlan0 power period 5
-	To disable deep sleep/auto deep sleep mode do:
-		iwconfig wlan0 power period -1

-     * During normal bootup, small reads may be required.
-     * Rather than issue an HIF Read and then wait as the Target
-     * adds successive bytes to the FIFO, we wait here until
-     * we know that response data is available.
-     *
-     * This allows us to cleanly timeout on an unexpected
-     * Target failure rather than risk problems at the HIF level.  In
-     * particular, this avoids SDIO timeouts and possibly garbage
-     * data on some host controllers.  And on an interconnect
-     * such as Compact Flash (as well as some SDIO masters) which
-     * does not provide any indication on data timeout, it avoids
-     * a potential hang or garbage response.
-     *
-     * Synchronization is more difficult for reads larger than the
-     * size of the MBOX FIFO (128B), because the Target is unable
-     * to push the 129th byte of data until AFTER the Host posts an
-     * HIF Read and removes some FIFO data.  So for large reads the
-     * Host proceeds to post an HIF Read BEFORE all the data is
-     * actually available to read.  Fortunately, large BMI reads do
-     * not occur in practice -- they're supported for debug/development.
-     *
-     * So Host/Target BMI synchronization is divided into these cases:
-     *  CASE 1: length < 4
-     *        Should not happen
-     *
-     *  CASE 2: 4 <= length <= 128
-     *        Wait for first 4 bytes to be in FIFO
-     *        If CONSERVATIVE_BMI_READ is enabled, also wait for
-     *        a BMI command credit, which indicates that the ENTIRE
-     *        response is available in the the FIFO
-     *
-     *  CASE 3: length > 128
-     *        Wait for the first 4 bytes to be in FIFO
-     *
-     * For most uses, a small timeout should be sufficient and we will
-     * usually see a response quickly; but there may be some unusual
-     * (debug) cases of BMI_EXECUTE where we want an larger timeout.
-     * For now, we use an unbounded busy loop while waiting for
-     * BMI_EXECUTE.
-     *
-     * If BMI_EXECUTE ever needs to support longer-latency execution,
-     * especially in production, this code needs to be enhanced to sleep
-     * and yield.  Also note that BMI_COMMUNICATION_TIMEOUT is currently

- * the unit test has the following constraints:
- *
- * The target has at least 8 buffers of 256 bytes each. The host will send
- * the following pattern of buffers in rapid succession :
- *
- * 1 buffer - 128 bytes
- * 1 buffer - 256 bytes
- * 1 buffer - 512 bytes
- * 1 buffer - 1024 bytes
- *
- * The host will send the buffers to one mailbox and wait for buffers to be reflected
- * back from the same mailbox. The target sends the buffers FIFO order.
- * Once the final buffer has been received for a mailbox, the next mailbox is tested.
- *
- *
- * Note:  To simplifythe test , we assume that the chosen buffer sizes

-/* Debug support on a per-module basis
- *
- * Usage:
- *
- *   Each module can utilize it's own debug mask variable.  A set of commonly used
- *   masks are provided (ERRORS, WARNINGS, TRACE etc..).  It is up to each module
- *   to define module-specific masks using the macros above.
- *
- *   Each module defines a single debug mask variable debug_XXX where the "name" of the module is
- *   common to all C-files within that module.  This requires every C-file that includes a_debug.h
- *   to define the module name in that file.
- *
- *   Example:
- *
- *   #define ATH_MODULE_NAME htc
- *   #include "a_debug.h"
- *
- *   This will define a debug mask structure called debug_htc and all debug macros will reference this
- *   variable.
- *
- *   A module can define module-specific bit masks using the ATH_DEBUG_MAKE_MODULE_MASK() macro:
- *
- *      #define ATH_DEBUG_MY_MASK1  ATH_DEBUG_MAKE_MODULE_MASK(0)
- *      #define ATH_DEBUG_MY_MASK2  ATH_DEBUG_MAKE_MODULE_MASK(1)
- *
- *   The instantiation of the debug structure should be made by the module.  When a module is
- *   instantiated, the module can set a description string, a default mask and an array of description
- *   entries containing information on each module-defined debug mask.
- *   NOTE: The instantiation is statically allocated, only one instance can exist per module.
- *
- *   Example:
- *
- *
- *   #define ATH_DEBUG_BMI  ATH_DEBUG_MAKE_MODULE_MASK(0)
- *
- *   #ifdef DEBUG
- *   static struct ath_debug_mask_description bmi_debug_desc[] = {
- *       { ATH_DEBUG_BMI , "BMI Tracing"},   <== description of the module specific mask
- *   };
- *
- *   ATH_DEBUG_INSTANTIATE_MODULE_VAR(bmi,
- *                                    "bmi"  <== module name
- *                                    "Boot Manager Interface",  <== description of module
- *                                    ATH_DEBUG_MASK_DEFAULTS,          <== defaults
- *                                    ATH_DEBUG_DESCRIPTION_COUNT(bmi_debug_desc),
- *                                    bmi_debug_desc);
- *
- *   #endif
- *
- *  A module can optionally register it's debug module information in order for other tools to change the
- *  bit mask at runtime.  A module can call  A_REGISTER_MODULE_DEBUG_INFO() in it's module
- *  init code.  This macro can be called multiple times without consequence.  The debug info maintains
- *  state to indicate whether the information was previously registered.

-/*
- * Bootloader Messaging Interface (BMI)
- *
- * BMI is a very simple messaging interface used during initialization
- * to read memory, write memory, execute code, and to define an
- * application entry PC.
- *
- * It is used to download an application to AR6K, to provide
- * patches to code that is already resident on AR6K, and generally
- * to examine and modify state.  The Host has an opportunity to use
- * BMI only once during bootup.  Once the Host issues a BMI_DONE
- * command, this opportunity ends.
- *
- * The Host writes BMI requests to mailbox0, and reads BMI responses
- * from mailbox0.   BMI requests all begin with a command
- * (see below for specific commands), and are followed by
- * command-specific data.
- *
- * Flow control:
- * The Host can only issue a command once the Target gives it a
- * "BMI Command Credit", using AR6K Counter #4.  As soon as the
- * Target has completed a command, it issues another BMI Command
- * Credit (so the Host can issue the next command).
- *
- * BMI handles all required Target-side cache flushing.

- * HIF CONFIGURE definitions:
- *
- *   HIF_DEVICE_GET_MBOX_BLOCK_SIZE
- *   input : none

- *   HIF_DEVICE_GET_MBOX_ADDR
- *   input : none
- *   output : struct hif_device_mbox_info
- *   notes: 
- *
- *   HIF_DEVICE_GET_PENDING_EVENTS_FUNC
- *   input : none
- *   output: HIF_PENDING_EVENTS_FUNC function pointer
- *   notes: this is optional for the HIF layer, if the request is
- *          not handled then it indicates that the upper layer can use
- *          the standard device methods to get pending events (IRQs, mailbox messages etc..)
- *          otherwise it can call the function pointer to check pending events.
- *
- *   HIF_DEVICE_GET_IRQ_PROC_MODE
- *   input : none
- *   output : HIF_DEVICE_IRQ_PROCESSING_MODE (interrupt processing mode)
- *   note: the hif layer interfaces with the underlying OS-specific bus driver. The HIF
- *         layer can report whether IRQ processing is requires synchronous behavior or
- *         can be processed using asynchronous bus requests (typically faster).
- *
- *   HIF_DEVICE_GET_RECV_EVENT_MASK_UNMASK_FUNC
- *   input :
- *   output : HIF_MASK_UNMASK_RECV_EVENT function pointer
- *   notes: this is optional for the HIF layer.  The HIF layer may require a special mechanism
- *          to mask receive message events.  The upper layer can call this pointer when it needs
- *          to mask/unmask receive events (in case it runs out of buffers).
- *
- *   HIF_DEVICE_POWER_STATE_CHANGE
- *
- *   input : HIF_DEVICE_POWER_CHANGE_TYPE
- *   output : none
- *   note: this is optional for the HIF layer.  The HIF layer can handle power on/off state change
- *         requests in an interconnect specific way.  This is highly OS and bus driver dependent.
- *         The caller must guarantee that no HIF read/write requests will be made after the device
- *         is powered down.
- *
- *   HIF_DEVICE_GET_IRQ_YIELD_PARAMS
- * 
- *   input : none
- *   output : struct hif_device_irq_yield_params
- *   note: This query checks if the HIF layer wishes to impose a processing yield count for the DSR handler.
- *   The DSR callback handler will exit after a fixed number of RX packets or events are processed.  
- *   This query is only made if the device reports an IRQ processing mode of HIF_DEVICE_IRQ_SYNC_ONLY. 
- *   The HIF implementation can ignore this command if it does not desire the DSR callback to yield.
- *   The HIF layer can indicate the maximum number of IRQ processing units (RX packets) before the
- *   DSR handler callback must yield and return control back to the HIF layer.  When a yield limit is 
- *   used the DSR callback will not call HIFAckInterrupts() as it would normally do before returning.  
- *   The HIF implementation that requires a yield count must call HIFAckInterrupt() when it is prepared
- *   to process interrupts again.
- *   
- *   HIF_CONFIGURE_QUERY_SCATTER_REQUEST_SUPPORT
- *   input : none
- *   output : struct hif_device_scatter_support_info
- *   note:  This query checks if the HIF layer implements the SCATTER request interface.  Scatter requests
- *   allows upper layers to submit mailbox I/O operations using a list of buffers.  This is useful for
- *   multi-message transfers that can better utilize the bus interconnect.
- * 
- * 
- *   HIF_DEVICE_GET_OS_DEVICE
- *   intput : none
- *   output : struct hif_device_os_device_info;
- *   note: On some operating systems, the HIF layer has a parent device object for the bus.  This object
- *         may be required to register certain types of logical devices.
- * 
- *   HIF_DEVICE_DEBUG_BUS_STATE
- *   input : none
- *   output : none
- *   note: This configure option triggers the HIF interface to dump as much bus interface state.  This 
- *   configuration request is optional (No-OP on some HIF implementations)

- * crc8
- *
- * Computes a crc8 over the input data using the polynomial:
- *
- *       x^8 + x^7 +x^6 + x^4 + x^2 + 1
- *
- * The caller provides the initial value (either CRC8_INIT_VALUE
- * or the previous returned value) to allow for processing of
- * discontiguous blocks of data.  When generating the CRC the
- * caller is responsible for complementing the final return value
- * and inserting it into the byte stream.  When checking, a final
- * return value of CRC8_GOOD_VALUE indicates a valid CRC.

+Cleaned up immensely by Olaf Hartman and Christoph Hellwig <hch@infradead.org>
 
 Note, the powermanagement options were removed from the vendor provided
 driver as they did not build properly at the time.
 
 TODO:
-	- kernel coding style cleanups
-	- forward port for latest network driver changes
-	- kill useless typecasts (e.g. in et1310_phy.c)
-	- alloc_etherdev is initializing memory with zero?!?
-	- add_timer call in et131x_netdev.c is correct?
-	- Add power saving functionality (suspend, sleep, resume)
-	- Implement a few more kernel Parameter (set mac )
+	- Use of kmem_cache seems a bit unusual
 
 Please send patches to:

+ * struct iio_buffer_access_funcs - access functions for buffers.
+ * @mark_in_use:	reference counting, typically to prevent module removal
+ * @unmark_in_use:	reduce reference count when no longer using buffer
+ * @store_to:		actually store stuff to the buffer
+ * @read_last:		get the last element stored
+ * @read_first_n:	try to get a specified number of elements (must exist)
+ * @mark_param_change:	notify buffer that some relevant parameter has changed
+ *			Often this means the underlying storage may need to
+ *			change.
+ * @request_update:	if a parameter change has been marked, update underlying
+ *			storage.
+ * @get_bytes_per_datum:get current bytes per datum
+ * @set_bytes_per_datum:set number of bytes per datum
+ * @get_length:		get number of datums in buffer
+ * @set_length:		set number of datums in buffer
+ * @is_enabled:		query if buffer is currently being used
+ * @enable:		enable the buffer
+ *
+ * The purpose of this structure is to make the buffer element
+ * modular as event for a given driver, different usecases may require
+ * different buffer designs (space efficiency vs speed for example).
+ *
+ * It is worth noting that a given buffer implementation may only support a
+ * small proportion of these functions.  The core code 'should' cope fine with
+ * any of them not existing.

-In the event that fragmentation is required, the incoming payload is split into
-N parts of size ieee->fts.  The first fragment contains the SNAP header and the
-remaining packets are just data.
-
-If encryption is enabled, each fragment payload size is reduced by enough space
-to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
-So if you have 1500 bytes of payload with ieee->fts set to 500 without
-encryption it will take 3 frames.  With WEP it will take 4 frames as the
-payload of each frame is reduced to 492 bytes.

+
+GNU General Public License
+
+Version 2, June 1991
+
+Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+59 Temple Place - Suite 330, Boston, MA  02111-1307, USA
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public License is intended
+to guarantee your freedom to share and change free software--to make sure
+the software is free for all its users. This General Public License applies
+to most of the Free Software Foundation's software and to any other program
+whose authors commit to using it. (Some other Free Software Foundation
+software is covered by the GNU Library General Public License instead.) You
+can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for this service if you
+wish), that you receive source code or can get it if you want it, that you
+can change the software or use pieces of it in new free programs; and that
+you know you can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to
+deny you these rights or to ask you to surrender the rights. These
+restrictions translate to certain responsibilities for you if you distribute
+copies of the software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must give the recipients all the rights that you have. You
+must make sure that they, too, receive or can get the source code. And you
+must show them these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2)
+offer you this license which gives you legal permission to copy, distribute
+and/or modify the software.
+
+Also, for each author's protection and ours, we want to make certain that
+everyone understands that there is no warranty for this free software. If
+the software is modified by someone else and passed on, we want its
+recipients to know that what they have is not the original, so that any
+problems introduced by others will not reflect on the original authors'
+reputations.
+
+Finally, any free program is threatened constantly by software patents. We
+wish to avoid the danger that redistributors of a free program will
+individually obtain patent licenses, in effect making the program
+proprietary. To prevent this, we have made it clear that any patent must be
+licensed for everyone's free use or not licensed at all.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License applies to any program or other work which contains a notice
+   placed by the copyright holder saying it may be distributed under the
+   terms of this General Public License. The "Program", below, refers to any
+   such program or work, and a "work based on the Program" means either the
+   Program or any derivative work under copyright law: that is to say, a
+   work containing the Program or a portion of it, either verbatim or with
+   modifications and/or translated into another language. (Hereinafter,
+   translation is included without limitation in the term "modification".)
+   Each licensee is addressed as "you".
+
+   Activities other than copying, distribution and modification are not
+   covered by this License; they are outside its scope. The act of running
+   the Program is not restricted, and the output from the Program is covered
+   only if its contents constitute a work based on the Program (independent
+   of having been made by running the Program). Whether that is true depends
+   on what the Program does.
+
+1. You may copy and distribute verbatim copies of the Program's source code
+   as you receive it, in any medium, provided that you conspicuously and
+   appropriately publish on each copy an appropriate copyright notice and
+   disclaimer of warranty; keep intact all the notices that refer to this
+   License and to the absence of any warranty; and give any other recipients
+   of the Program a copy of this License along with the Program.
+
+   You may charge a fee for the physical act of transferring a copy, and you
+   may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Program or any portion of it,
+   thus forming a work based on the Program, and copy and distribute such
+   modifications or work under the terms of Section 1 above, provided that
+   you also meet all of these conditions:
+
+   * a) You must cause the modified files to carry prominent notices stating
+        that you changed the files and the date of any change.
+
+   * b) You must cause any work that you distribute or publish, that in
+        whole or in part contains or is derived from the Program or any part
+        thereof, to be licensed as a whole at no charge to all third parties
+        under the terms of this License.
+
+   * c) If the modified program normally reads commands interactively when
+        run, you must cause it, when started running for such interactive
+        use in the most ordinary way, to print or display an announcement
+        including an appropriate copyright notice and a notice that there is
+        no warranty (or else, saying that you provide a warranty) and that
+        users may redistribute the program under these conditions, and
+        telling the user how to view a copy of this License. (Exception: if
+        the Program itself is interactive but does not normally print such
+        an announcement, your work based on the Program is not required to
+        print an announcement.)
+
+   These requirements apply to the modified work as a whole. If identifiable
+   sections of that work are not derived from the Program, and can be
+   reasonably considered independent and separate works in themselves, then
+   this License, and its terms, do not apply to those sections when you
+   distribute them as separate works. But when you distribute the same
+   sections as part of a whole which is a work based on the Program, the
+   distribution of the whole must be on the terms of this License, whose
+   permissions for other licensees extend to the entire whole, and thus to
+   each and every part regardless of who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Program.
+
+   In addition, mere aggregation of another work not based on the Program
+   with the Program (or with a work based on the Program) on a volume of a
+   storage or distribution medium does not bring the other work under the
+   scope of this License.
+
+3. You may copy and distribute the Program (or a work based on it, under
+   Section 2) in object code or executable form under the terms of Sections
+   1 and 2 above provided that you also do one of the following:
+
+   * a) Accompany it with the complete corresponding machine-readable source
+        code, which must be distributed under the terms of Sections 1 and 2
+        above on a medium customarily used for software interchange; or,
+
+   * b) Accompany it with a written offer, valid for at least three years,
+        to give any third party, for a charge no more than your cost of
+        physically performing source distribution, a complete machine-
+        readable copy of the corresponding source code, to be distributed
+        under the terms of Sections 1 and 2 above on a medium customarily
+        used for software interchange; or,
+
+   * c) Accompany it with the information you received as to the offer to
+        distribute corresponding source code. (This alternative is allowed
+        only for noncommercial distribution and only if you received the
+        program in object code or executable form with such an offer, in
+        accord with Subsection b above.)
+
+   The source code for a work means the preferred form of the work for
+   making modifications to it. For an executable work, complete source code
+   means all the source code for all modules it contains, plus any
+   associated interface definition files, plus the scripts used to control
+   compilation and installation of the executable. However, as a special
+   exception, the source code distributed need not include anything that is
+   normally distributed (in either source or binary form) with the major
+   components (compiler, kernel, and so on) of the operating system on which
+   the executable runs, unless that component itself accompanies the
+   executable.
+
+   If distribution of executable or object code is made by offering access
+   to copy from a designated place, then offering equivalent access to copy
+   the source code from the same place counts as distribution of the source
+   code, even though third parties are not compelled to copy the source
+   along with the object code.
+
+4. You may not copy, modify, sublicense, or distribute the Program except as
+   expressly provided under this License. Any attempt otherwise to copy,
+   modify, sublicense or distribute the Program is void, and will
+   automatically terminate your rights under this License. However, parties
+   who have received copies, or rights, from you under this License will not
+   have their licenses terminated so long as such parties remain in full
+   compliance.
+
+5. You are not required to accept this License, since you have not signed
+   it. However, nothing else grants you permission to modify or distribute
+   the Program or its derivative works. These actions are prohibited by law
+   if you do not accept this License. Therefore, by modifying or
+   distributing the Program (or any work based on the Program), you
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Program or works
+   based on it.
+
+6. Each time you redistribute the Program (or any work based on the
+   Program), the recipient automatically receives a license from the
+   original licensor to copy, distribute or modify the Program subject to
+   these terms and conditions. You may not impose any further restrictions
+   on the recipients' exercise of the rights granted herein. You are not
+   responsible for enforcing compliance by third parties to this License.
+
+7. If, as a consequence of a court judgment or allegation of patent
+   infringement or for any other reason (not limited to patent issues),
+   conditions are imposed on you (whether by court order, agreement or
+   otherwise) that contradict the conditions of this License, they do not
+   excuse you from the conditions of this License. If you cannot distribute
+   so as to satisfy simultaneously your obligations under this License and
+   any other pertinent obligations, then as a consequence you may not
+   distribute the Program at all. For example, if a patent license would
+   not permit royalty-free redistribution of the Program by all those who
+   receive copies directly or indirectly through you, then the only way you
+   could satisfy both it and this License would be to refrain entirely from
+   distribution of the Program.
+
+   If any portion of this section is held invalid or unenforceable under any
+   particular circumstance, the balance of the section is intended to apply
+   and the section as a whole is intended to apply in other circumstances.
+
+   It is not the purpose of this section to induce you to infringe any
+   patents or other property right claims or to contest validity of any
+   such claims; this section has the sole purpose of protecting the
+   integrity of the free software distribution system, which is implemented
+   by public license practices. Many people have made generous contributions
+   to the wide range of software distributed through that system in
+   reliance on consistent application of that system; it is up to the
+   author/donor to decide if he or she is willing to distribute software
+   through any other system and a licensee cannot impose that choice.
+
+   This section is intended to make thoroughly clear what is believed to be
+   a consequence of the rest of this License.
+
+8. If the distribution and/or use of the Program is restricted in certain
+   countries either by patents or by copyrighted interfaces, the original
+   copyright holder who places the Program under this License may add an
+   explicit geographical distribution limitation excluding those countries,
+   so that distribution is permitted only in or among countries not thus
+   excluded. In such case, this License incorporates the limitation as if
+   written in the body of this License.
+
+9. The Free Software Foundation may publish revised and/or new versions of
+   the General Public License from time to time. Such new versions will be
+   similar in spirit to the present version, but may differ in detail to
+   address new problems or concerns.
+
+   Each version is given a distinguishing version number. If the Program
+   specifies a version number of this License which applies to it and "any
+   later version", you have the option of following the terms and
+   conditions either of that version or of any later version published by
+   the Free Software Foundation. If the Program does not specify a version
+   number of this License, you may choose any version ever published by the
+   Free Software Foundation.
+
+10. If you wish to incorporate parts of the Program into other free programs
+    whose distribution conditions are different, write to the author to ask
+    for permission. For software which is copyrighted by the Free Software
+    Foundation, write to the Free Software Foundation; we sometimes make
+    exceptions for this. Our decision will be guided by the two goals of
+    preserving the free status of all derivatives of our free software and
+    of promoting the sharing and reuse of software generally.
+
+   NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+    FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+    PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH
+    YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+    REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it free
+software which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to
+attach them to the start of each source file to most effectively convey the
+exclusion of warranty; and each file should have at least the "copyright"
+line and a pointer to where the full notice is found.
+
+one line to give the program's name and an idea of what it does.
+Copyright (C) yyyy  name of author
+
+This program is free software; you can redistribute it and/or modify it
+under the terms of the GNU General Public License as published by the Free
+Software Foundation; either version 2 of the License, or (at your option)
+any later version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE.  See the GNU General Public License for
+more details.
+
+You should have received a copy of the GNU General Public License along with
+this program; if not, write to the Free Software Foundation, Inc., 59
+Temple Place - Suite 330, Boston, MA  02111-1307, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this when
+it starts in an interactive mode:
+
+Gnomovision version 69, Copyright (C) year name of author Gnomovision comes
+with ABSOLUTELY NO WARRANTY; for details type 'show w'.  This is free
+software, and you are welcome to redistribute it under certain conditions;
+type 'show c' for details.
+
+The hypothetical commands 'show w' and 'show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may be
+called something other than 'show w' and 'show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+'Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+signature of Ty Coon, 1 April 1989
+Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General Public
+License instead of this License.

+
+In the event that fragmentation is required, the incoming payload is split into
+N parts of size ieee->fts.  The first fragment contains the SNAP header and the
+remaining packets are just data.
+
+If encryption is enabled, each fragment payload size is reduced by enough space
+to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
+So if you have 1500 bytes of payload with ieee->fts set to 500 without
+encryption it will take 3 frames.  With WEP it will take 4 frames as the
+payload of each frame is reduced to 492 bytes.

+PRELIMINARY DRAFT, MAY CONTAIN MISTAKES!
+28 Jun 2011
+
+The USB/IP protocol follows a server/client architecture. The server exports the
+USB devices and the clients imports them. The device driver for the exported
+USB device runs on the client machine.
+
+The client may ask for the list of the exported USB devices. To get the list the
+client opens a TCP/IP connection towards the server, and sends an OP_REQ_DEVLIST
+packet on top of the TCP/IP connection (so the actual OP_REQ_DEVLIST may be sent
+in one or more pieces at the low level transport layer). The server sends back
+the OP_REP_DEVLIST packet which lists the exported USB devices. Finally the
+TCP/IP connection is closed.

+Once the client knows the list of exported USB devices it may decide to use one
+of them. First the client opens a TCP/IP connection towards the server and
+sends an OP_REQ_IMPORT packet. The server replies with OP_REP_IMPORT. If the
+import was successful the TCP/IP connection remains open and will be used
+to trasfer the URB traffic between the client and the server. The client may
+send two types of packets: the USBIP_CMD_SUBMIT to submit an URB, and
+USBIP_CMD_UNLINK to unlink a previously submitted URB. The answers of the
+server may be USBIP_RET_SUBMIT and USBIP_RET_UNLINK respectively.

-structure should be correctly set. The '.name' element is a pointer to a string
-holding the device driver's name. The '.probe' element should contain a pointer
-to the probe routine.
-
-The arguments of the probe routine are as follows:
-
-	probe(struct device *dev, int bus, int slot);
-
-The '.bind_table' is a pointer to an array of type 'vme_device_id':
-
-	struct vme_device_id {
-		int bus;
-		int slot;
+At the minimum, the '.name', '.match' and '.probe' elements of this structure
+should be correctly set. The '.name' element is a pointer to a string holding
+the device driver's name.
+
+The '.match' function allows controlling the number of devices that need to
+be registered. The match function should return 1 if a device should be
+probed and 0 otherwise. This example match function (from vme_user.c) limits
+the number of devices probed to one:
+
+	#define USER_BUS_MAX	1
+	...
+	static int vme_user_match(struct vme_dev *vdev)
+	{
+		if (vdev->id.num >= USER_BUS_MAX)
+			return 0;
+		return 1;
+	}
+
+The '.probe' element should contain a pointer to the probe routine. The
+probe routine is passed a 'struct vme_dev' pointer as an argument. The
+'struct vme_dev' structure looks like the following:
+
+	struct vme_dev {
+		int num;
+		struct vme_bridge *bridge;
+		struct device dev;
+		struct list_head drv_list;
+		struct list_head bridge_list;
 	};
 
-Each structure in this array should provide a bus and slot number where the core
-should probe, using the driver's probe routine, for a device on the specified
-VME bus.
-
-The VME subsystem supports a single VME driver per 'slot'. There are considered
-to be 32 slots per bus, one for each slot-ID as defined in the ANSI/VITA 1-1994
-specification and are analogious to the physical slots on the VME backplane.

-*
-*.CONDITIONS
-* Except for hcf_action with HCF_ACT_INT_FORCE_ON or HCF_ACT_INT_OFF as parameter or hcf_connect with an I/O
-* address (i.e. not HCF_DISCONNECT), all hcf-function calls MUST be preceded by a call of hcf_action with
-* HCF_ACT_INT_OFF as parameter.
-* Note that hcf_connect defaults to NIC interrupt disabled mode, i.e. as if hcf_action( HCF_ACT_INT_OFF )
-* was called.
-*
-*.DESCRIPTION
-* hcf_action supports the following mode changing action-code pairs that are antonyms
-*	 - HCF_ACT_CCX_OFF / HCF_ACT_CCX_ON
-*	 - HCF_ACT_INT_[FORCE_]ON / HCF_ACT_INT_OFF
-*
-* Additionally hcf_action can start the following actions in the NIC:
-*	 - HCF_ACT_PRS_SCAN
-*	 - HCF_ACT_RX_ACK
-*	 - HCF_ACT_SCAN
-*	 - HCF_ACT_SLEEP
-*	 - HCF_ACT_TALLIES
-*
-* o HCF_ACT_INT_OFF: Sets NIC Interrupts mode Disabled.
-* This command, and the associated [Force] Enable NIC interrupts command, are only available if the HCF_INT_ON
-* compile time option is not set at 0x0000.
-*
-* o HCF_ACT_INT_ON: Sets NIC Interrupts mode Enabled.
-* Enable NIC Interrupts, depending on the number of preceding Disable NIC Interrupt calls.
-*
-* o HCF_ACT_INT_FORCE_ON: Force NIC Interrupts mode Enabled.
-* Sets NIC Interrupts mode Enabled, regardless off the number of preceding Disable NIC Interrupt calls.
-*
-* The disabling and enabling of interrupts are antonyms.
-* These actions must be balanced.
-* For each "disable interrupts" there must be a matching "enable interrupts".
-* The disable interrupts may be executed multiple times in a row without intervening enable interrupts, in
-* other words, the disable interrupts may be nested.
-* The interrupt generation mechanism is disabled at the first call with HCF_ACT_INT_OFF.
-* The interrupt generation mechanism is re-enabled when the number of calls with HCF_ACT_INT_ON matches the
-* number of calls with INT_OFF.
-*
-* It is not allowed to have more Enable NIC Interrupts calls than Disable NIC Interrupts calls.
-* The interrupt generation mechanism is initially (i.e. after hcf_connect) disabled.
-* An MSF based on a interrupt strategy must call hcf_action with INT_ON in its initialization logic.
-*
-*!	The INT_OFF/INT_ON housekeeping is initialized at 0x0000 by hcf_connect, causing the interrupt generation
-*	mechanism to be disabled at first. This suits MSF implementation based on a polling strategy.
-*
-* o HCF_ACT_CCX_OFF / HCF_ACT_CCX_ON
-*!! This can use some more explanation;?
-* Disables and Enables support in the HCF runtime code for the CCX feature. Each time one of these action
-* codes is used, the effects of the preceding use cease.
-*
-* o HCF_ACT_SLEEP: Initiates the Disconnected DeepSleep process
-* This command is only available if the HCF_DDS compile time option is set. It triggers the F/W to start the
-* sleep handshaking. Regardless whether the Host initiates a Disconnected DeepSleep (DDS) or the F/W initiates
-* a Connected DeepSleep (CDS), the Host-F/W sleep handshaking is completed when the NIC Interrupts mode is
-* enabled (by means of the balancing HCF_ACT_INT_ON), i.e. at that moment the F/W really goes into sleep mode.
-* The F/W is wokenup by the HCF when the NIC Interrupts mode are disabled, i.e. at the first HCF_ACT_INT_OFF
-* after going into sleep.
-*
-* The following Miscellanuous actions are defined:
-*
-* o HCF_ACT_RX_ACK: Receiver Acknowledgement (non-DMA, non-USB mode only)
-* Acking the receiver, frees the NIC memory used to hold the Rx frame and allows the F/W to
-* report the existence of the next Rx frame.
-* If the MSF does not need access (any longer) to the current frame, e.g. because it is rejected based on the
-* look ahead or copied to another buffer, the receiver may be acked. Acking earlier is assumed to have the
-* potential of improving the performance.
-* If the MSF does not explitly ack te receiver, the acking is done implicitly if:
-* - the received frame fits in the look ahead buffer, by the hcf_service_nic call that reported the Rx frame
-* - if not in the above step, by hcf_rcv_msg (assuming hcf_rcv_msg is called)
-* - if neither of the above implicit acks nor an explicit ack by the MSF, by the first hcf_service_nic after
-*	the hcf_service_nic that reported the Rx frame.
-* Note: If an Rx frame is already acked, an explicit ACK by the MSF acts as a NoOperation.
-*
-* o HCF_ACT_TALLIES: Inquire Tallies command
-* This command is only operational if the F/W is enabled.
-* The Inquire Tallies command requests the F/W to provide its current set of tallies.
-* See also hcf_get_info with CFG_TALLIES as parameter.
-*
-* o HCF_ACT_PRS_SCAN: Inquire Probe Respons Scan command
-* This command is only operational if the F/W is enabled.
-* The Probe Respons Scan command starts a scan sequence.
-* The HCF puts the result of this action in an MSF defined buffer (see CFG_RID_LOG_STRCT).
-*
-* o HCF_ACT_SCAN: Inquire Scan command
-* This command is only supported for HII F/W (i.e. pre-WARP) and it is operational if the F/W is enabled.
-* The Inquire Scan command starts a scan sequence.
-* The HCF puts the result of this action in an MSF defined buffer (see CFG_RID_LOG_STRCT).
-*
-* Assert fails if
-* - ifbp has a recognizable out-of-range value.
-* - NIC interrupts are not disabled while required by parameter action.
-* - an invalid code is specified in parameter action.
-* - HCF_ACT_INT_ON commands outnumber the HCF_ACT_INT_OFF commands.
-* - reentrancy, may be  caused by calling hcf_functions without adequate protection against NIC interrupts or
-*	multi-threading
-*
-* - Since the HCF does not maintain status information relative to the F/W enabled state, it is not asserted
-*	whether HCF_ACT_SCAN, HCF_ACT_PRS_SCAN or HCF_ACT_TALLIES are only used while F/W is enabled.
-*
-*.DIAGRAM
-* 0: The assert embedded in HCFLOGENTRY checks against re-entrancy. Re-entrancy could be caused by a MSF logic
-*	at task-level calling hcf_functions without shielding with HCF_ACT_ON/_OFF. However the HCF_ACT_INT_OFF
-*	action itself can per definition not be protected this way. Based on code inspection, it can be concluded,
-*	that there is no re-entrancy PROBLEM in this particular flow. It does not seem worth the trouble to
-*	explicitly check for this condition (although there was a report of an MSF which ran into this assert.
-* 2:IFB_IntOffCnt is used to balance the INT_OFF and INT_ON calls.  Disabling of the interrupts is achieved by
-*	writing a zero to the Hermes IntEn register.  In a shared interrupt environment (e.g. the mini-PCI NDIS
-*	driver) it is considered more correct to return the status HCF_INT_PENDING if and only if, the current
-*	invocation of hcf_service_nic is (apparently) called in the ISR when the ISR was activated as result of a
-*	change in HREG_EV_STAT matching a bit in HREG_INT_EN, i.e. not if invoked as result of another device
-*	generating an interrupt on the shared interrupt line.
-*	Note 1: it has been observed that under certain adverse conditions on certain platforms the writing of
-*	HREG_INT_EN can apparently fail, therefor it is paramount that HREG_INT_EN is written again with 0 for
-*	each and every call to HCF_ACT_INT_OFF.
-*	Note 2: it has been observed that under certain H/W & S/W architectures this logic is called when there is
-*	no NIC at all. To cater for this, the value of HREG_INT_EN is validated. If the unused bit 0x0100 is set,
-*	it is assumed there is no NIC.
-*	Note 3: During the download process, some versions of the F/W reset HREG_SW_0, hence checking this
-*	register for HCF_MAGIC (the classical NIC presence test) when HCF_ACT_INT_OFF is called due to another
-*	card interrupting via a shared IRQ during a download, fails.
-*4:	The construction "if ( ifbp->IFB_IntOffCnt-- == 0 )" is optimal (in the sense of shortest/quickest
-*	path in error free flows) but NOT fail safe in case of too many INT_ON invocations compared to INT_OFF).
-*	Enabling of the interrupts is achieved by writing the Hermes IntEn register.
-*	 - If the HCF is in Defunct mode, the interrupts stay disabled.
-*	 - Under "normal" conditions, the HCF is only interested in Info Events, Rx Events and Notify Events.
-*	 - When the HCF is out of Tx/Notify resources, the HCF is also interested in Alloc Events.
-*	 - via HCF_EXT, the MSF programmer can also request HREG_EV_TICK and/or HREG_EV_TX_EXC interrupts.
-*	For DMA operation, the DMA hardware handles the alloc events. The DMA engine will generate a 'TxDmaDone'
-*	event as soon as it has pumped a frame from host ram into NIC-RAM (note that the frame does not have to be
-*	transmitted then), and a 'RxDmaDone' event as soon as a received frame has been pumped from NIC-RAM into
-*	host ram.  Note that the 'alloc' event has been removed from the event-mask, because the DMA engine will
-*	react to and acknowledge this event.
-*6:	ack the "old" Rx-event. See "Rx Buffer free strategy" in hcf_service_nic above for more explanation.
-*	IFB_RxFID and IFB_RxLen must be cleared to bring both the internal HCF house keeping and the information
-*	supplied to the MSF in the state "no frame received".
-*8:	The HCF_ACT_SCAN, HCF_ACT_PRS_SCAN and HCF_ACT_TALLIES activity are merged by "clever" algebraic
-*	manipulations of the RID-values and action codes, so foregoing robustness against migration problems for
-*	ease of implementation. The assumptions about numerical relationships between CFG_TALLIES etc and
-*	HCF_ACT_TALLIES etc are checked by the "#if" statements just prior to the body of this routine, resulting
-*	in: err "maintenance" during compilation if the assumptions are no longer met. The writing of HREG_PARAM_1
-*	with 0x3FFF in case of an PRS scan, is a kludge to get around lack of specification, hence different
-*	implementation in F/W and Host.
-*	When there is no NIC RAM available, some versions of the Hermes F/W do report 0x7F00 as error in the
-*	Result field of the Status register and some F/W versions don't. To mask this difference to the MSF all
-*	return codes of the Hermes are ignored ("best" and "most simple" solution to these types of analomies with
-*	an acceptable loss due to ignoring all error situations as well).
-*	The "No inquire space" is reported via the Hermes tallies.
-*30: do not HCFASSERT( rc, rc ) since rc == HCF_INT_PENDING is no error

+ *   ease of implementation. The assumptions about numerical relationships between CFG_TALLIES etc and
+ *   HCF_ACT_TALLIES etc are checked by the "#if" statements just prior to the body of this routine, resulting
+ *   in: err "maintenance" during compilation if the assumptions are no longer met. The writing of HREG_PARAM_1
+ *   with 0x3FFF in case of an PRS scan, is a kludge to get around lack of specification, hence different
+ *   implementation in F/W and Host.
+ *   When there is no NIC RAM available, some versions of the Hermes F/W do report 0x7F00 as error in the
+ *   Result field of the Status register and some F/W versions don't. To mask this difference to the MSF all
+ *   return codes of the Hermes are ignored ("best" and "most simple" solution to these types of analomies with
+ *   an acceptable loss due to ignoring all error situations as well).
+ *   The "No inquire space" is reported via the Hermes tallies.
+ *30: do not HCFASSERT( rc, rc ) since rc == HCF_INT_PENDING is no error

-*
-* The Connect is used by the MSF to bring a particular port in an inactive state as far as data transmission

-* When a particular port is disconnected:
-* - the F/W disables the receiver for that port.
-* - the F/W ignores send commands for that port.
-* - all frames (Receive as well as pending Transmit) for that port on the NIC are discarded.
-*
-* When the NIC is disabled, above list applies to all ports, i.e. the result is like all ports are
-* disconnected.
-*
-* When a particular port is connected:
-* - the F/W effectuates the static configuration for that port.
-* - enables the receiver for that port.
-* - accepts send commands for that port.
-*
-* Enabling has the following effects:
-* - the F/W effectuates the static configuration for all ports.
-*	The F/W only updates its static configuration at a transition from disabled to enabled or from
-*	disconnected to connected.
-*	In order to enforce the static configuration, the MSF must assure that such a transition takes place.
-*	Due to such a disable/enable or disconnect/connect sequence, Rx/Tx frames may be lost, in other words,

-* - The DMA Engine (if applicable) is enabled.

-*
-*	MSF-accessible fields of Result Block:

-*	IFB_HSISup				CFG_SUP_RANGE_STRCT, specifies the HW/SW I/F range of the NIC
-*	IFB_PRIIdentity			CFG_PRI_IDENTITY_STRCT, specifies the Identity of the Primary F/W
-*	IFB_PRISup				CFG_SUP_RANGE_STRCT, specifies the supplier range of the Primary F/W
-*	all other				all MSF accessible fields, which are not specified above, are zero-filled
-*
-*.CONDITIONS
-* It is the responsibility of the MSF to assure the correctness of the I/O Base address.
-*
-* Note: hcf_connect defaults to NIC interrupt disabled mode, i.e. as if hcf_action( HCF_ACT_INT_OFF )
-* was called.
-*
-*.DESCRIPTION
-* hcf_connect passes the MSF-defined location of the IFB to the HCF and grants or revokes access right for the
-* HCF to the IFB. Revoking is done by specifying HCF_DISCONNECT rather than an I/O address for the parameter
-* io_base.  Every call of hcf_connect in "connect" mode, must eventually be followed by a call of hcf_connect
-* in "disconnect" mode. Clalling hcf_connect in "connect"/"disconnect" mode can not be nested.
-* The IFB address must be used as a handle with all subsequent HCF-function calls and the HCF uses the IFB
-* address as a handle when it performs a call(back) of an MSF-function (i.e. msf_assert).
-*
-* Note that not only the MSF accessible fields are cleared, but also all internal housekeeping
-* information is re-initialized.
-* This implies that all settings which are done via hcf_action and hcf_put_info (e.g. CFG_MB_ASSERT, CFG_REG_MB,
-* CFG_REG_INFO_LOG) must be done again. The only field which is not cleared, is IFB_MSFSup.
-*
-* If HCF_INT_ON is selected as compile option, NIC interrupts are disabled.
-*
-* Assert fails if
-* - ifbp is not properly aligned ( ref chapter HCF_ALIGN in 4.1.1)
-* - I/O Base Address is not a multiple of 0x40 (note: 0x0000 is explicitly allowed).
-*
-*.DIAGRAM
-*
-*0:	Throughout hcf_connect you need to distinguish the connect from the disconnect case, which requires
-*	some attention about what to use as "I/O" address when for which purpose.
-*2:
-*2a: Reset H-II by toggling reset bit in IO-register on and off.
-*	The HCF_TYPE_PRELOADED caters for the DOS environment where H-II is loaded by a separate program to
-*	overcome the 64k size limit posed on DOS drivers.
-*	The macro OPW is not yet useable because the IFB_IOBase field is not set.
-*	Note 1: hopefully the clearing and initializing of the IFB (see below) acts as a delay which meets the
-*	specification for S/W reset
-*	Note 2: it turns out that on some H/W constellations, the clock to access the EEProm is not lowered
-*	to an appropriate frequency by HREG_IO_SRESET. By giving an HCMD_INI first, this problem is worked around.
-*2b: Experimentally it is determined over a wide range of F/W versions that waiting for the for Cmd bit in
-*	Ev register gives a workable strategy. The available documentation does not give much clues.
-*4:	clear and initialize the IFB
-*	The HCF house keeping info is designed such that zero is the appropriate initial value for as much as
-*	feasible IFB-items.
-*	The readable fields mentioned in the description section and some HCF specific fields are given their
-*	actual value.
-*	IFB_TickIni is initialized at best guess before calibration
-*	Hcf_connect defaults to "no interrupt generation" (implicitly achieved by the zero-filling).
-*6:	Register compile-time linked MSF Routine and set default filter level
-*	cast needed to get around the "near" problem in DOS COM model
-*	er C2446: no conversion from void (__near __cdecl *)(unsigned char __far *,unsigned int,unsigned short,int)
-*							to   void (__far  __cdecl *)(unsigned char __far *,unsigned int,unsigned short,int)
-*8:	If a command is apparently still active (as indicated by the Busy bit in Cmd register) this may indicate a
-*	blocked cmd pipe line.  To unblock the following actions are done:
-*	 - Ack everything
-*	 - Wait for Busy bit drop  in Cmd register
-*	 - Wait for Cmd  bit raise in Ev  register
-*	The two waits are combined in a single HCF_WAIT_WHILE to optimize memory size. If either of these waits
-*	fail (prot_cnt becomes 0), then something is serious wrong. Rather than PANICK, the assumption is that the
-*	next cmd_exe will fail, causing the HCF to go into DEFUNCT mode
-*10:	Ack everything to unblock a (possibly blocked) cmd pipe line
-*	Note 1: it is very likely that an Alloc event is pending and very well possible that a (Send) Cmd event is
-*	pending on non-initial calls
-*	Note 2: it is assumed that this strategy takes away the need to ack every conceivable event after an
-*	Hermes Initialize
-*12:	Only H-II NEEDS the Hermes Initialize command. Due to the different semantics for H-I and H-II
-*	Initialize command, init() does not (and can not, since it is called e.g. after a download) execute the
-*	Hermes Initialize command. Executing the Hermes Initialize command for H-I would not harm but not do
-*	anything useful either, so it is skipped.
-*	The return status of cmd_exe is ignored. It is assumed that if cmd_exe fails, init fails too
-*14:	use io_base as a flag to merge hcf_connect and hcf_disconnect into 1 routine
-*	the call to init and its subsequent call of cmd_exe will return HCF_ERR_NO_NIC if appropriate. This status
-*	is (badly) needed by some legacy combination of NT4 and card services which do not yield an I/O address in
-*	time.
-*
-*.NOTICE
-*	On platforms where the NULL-pointer is not a bit-pattern of all zeros, the zero-filling of the IFB results
-*	in an incorrect initialization of pointers.
-*	The implementation of the MailBox manipulation in put_mb_info protects against the absence of a MailBox
-*	based on IFB_MBSize, IFB_MBWp and ifbp->IFB_MBRp. This has ramifications on the initialization of the
-*	MailBox via hcf_put_info with the CFG_REG_MB type, but it prevents dependency on the "NULL-"ness of
-*	IFB_MBp.
-*
-*.NOTICE
-*	There are a number of problems when asserting and logging hcf_connect, e.g.
-*	 - Asserting on re-entrancy of hcf_connect by means of
-*	 "HCFASSERT( (ifbp->IFB_AssertTrace & HCF_ASSERT_CONNECT) == 0, 0 )" is not useful because IFB contents
-*	 are undefined
-*	 - Asserting before the IFB is cleared will cause mdd_assert() to interpret the garbage in IFB_AssertRtn
-*	 as a routine address
-*	Therefore HCFTRACE nor HCFLOGENTRY is called by hcf_connect.

-*
-*.DESCRIPTION
-* The HCF can be used in 2 fashions: with and without encapsulation for data transfer.
-* This is controlled at compile time by the HCF_ENC bit of the HCF_ENCAP system constant.
-*
-* Regardless of the HCF_ENCAP system constant, the descriptor list created to describe the frame to be
-* transmitted, must supply space to contain the 802.11 header, preceding the actual frame to be transmitted.
-* Basically, this only supplies working storage to the HCF which passes this on to the DMA engine.
-* As a consequence the contents of this space do not matter.
-* Nevertheless BUF_CNT must take in account this storage.
-* This working space to contain the 802.11 header may not be fragmented, the first buffer must be
-* sufficiently large to contain at least the 802.11 header, i.e. HFS_ADDR_DEST (29 words or 0x3A bytes).
-* This way, the HCF can simply, regardless whether or not the HCF encapsulates the frame, write the parameter
-* tx_cntl at offset 0x36 (HFS_TX_CNTL) in the first buffer.
-* Note that it is allowed to have part or all of the actual frame represented by the first descriptor as long
-* as the requirement for storage for the 802.11 header is met, i.e. the 802.3 frame starts at offset
-* HFS_ADDR_DEST.
-* Except for the Assert on the 1st buffer in case of Encapsualtion, the SIZE fields are ignored.
-*
-* In case the encapsulation feature is compiled in, there are the following additional requirements.
-* o The BUF_CNT of the first buffer changes from a minimum of 0x3A bytes to exactly 0x3A, i.e. the workspace
-*	to store the 802.11 header
-* o The BUF_SIZE of the first buffer is at least the space needed to store the
-*	- 802.11 header (29 words)
-*	- 802.3 header, i.e. 12 bytes addressing information and 2 bytes length field
-*	- 6 bytes SNAP-header
-*   This results in 39 words or 0x4E bytes or HFS_TYPE.
-*   Note that if the BUF_SIZE is larger than 0x4E, this surplus is not used.
-* o The actual frame begins in the 2nd descriptor (which is already implied by the BUF_CNT == 0x3A requirement) and the associated buffer contains at least the 802.3 header, i.e. the 14 bytes representing addressing information and length/type field
-*
-*   When the HCF does not encapsulates (i.e. length/type field <= 1500),  no changes are made to descriptors
-*   or buffers.
-*
-*   When the HCF actually encapsulates (i.e. length/type field > 1500), it successively writes, starting at
-*   offset HFS_ADDR_DEST (0x3A) in the first buffer:
-*     - the 802.3 addressing information, copied from the begin of the second buffer
-*     - the frame length, derived from the total length of the individual fragments, corrected for the SNAP
-*   	header length and Type field and ignoring the Destination Address, Source Address and Length field
-* 	  - the appropriate snap header (Tunnel or 1042, depending on the value of the type field).
-*
-* 	 The information in the first two descriptors is adjusted accordingly:
-* 	  - the first descriptor count is changed from 0x3A to 0x4E (HFS_TYPE), which matches 0x3A + 12 + 2 + 6
-* 	  - the second descriptor count is decreased by 12, being the moved addressing information
-* 	  - the second descriptor (physical) buffer address is increased by 12.
-*
-* When the descriptors are returned by hcf_dma_tx_get, the transformation of the first two descriptors is
-* undone.

+ *.PURPOSE       puts a packet in the Tx DMA queue in host ram and kicks off the TxDma engine.
+ *               supply the Tx-DELWA descriptor.
+ *
+ *.ARGUMENTS
+ *   ifbp        address of the Interface Block
+ *   descp       address of Tx Descriptor Chain (i.e. a single Tx frame)
+ *   tx_cntl     indicates MAC-port and (Hermes) options
+ *
+ *.RETURNS       N.A.
+ *
+ *.DESCRIPTION
+ * The HCF can be used in 2 fashions: with and without encapsulation for data transfer.
+ * This is controlled at compile time by the HCF_ENC bit of the HCF_ENCAP system constant.
+ *
+ * Regardless of the HCF_ENCAP system constant, the descriptor list created to describe the frame to be
+ * transmitted, must supply space to contain the 802.11 header, preceding the actual frame to be transmitted.
+ * Basically, this only supplies working storage to the HCF which passes this on to the DMA engine.
+ * As a consequence the contents of this space do not matter.
+ * Nevertheless BUF_CNT must take in account this storage.
+ * This working space to contain the 802.11 header may not be fragmented, the first buffer must be
+ * sufficiently large to contain at least the 802.11 header, i.e. HFS_ADDR_DEST (29 words or 0x3A bytes).
+ * This way, the HCF can simply, regardless whether or not the HCF encapsulates the frame, write the parameter
+ * tx_cntl at offset 0x36 (HFS_TX_CNTL) in the first buffer.
+ * Note that it is allowed to have part or all of the actual frame represented by the first descriptor as long
+ * as the requirement for storage for the 802.11 header is met, i.e. the 802.3 frame starts at offset
+ * HFS_ADDR_DEST.
+ * Except for the Assert on the 1st buffer in case of Encapsualtion, the SIZE fields are ignored.
+ *
+ * In case the encapsulation feature is compiled in, there are the following additional requirements.
+ * o The BUF_CNT of the first buffer changes from a minimum of 0x3A bytes to exactly 0x3A, i.e. the workspace
+ *   to store the 802.11 header
+ * o The BUF_SIZE of the first buffer is at least the space needed to store the
+ *   - 802.11 header (29 words)
+ *   - 802.3 header, i.e. 12 bytes addressing information and 2 bytes length field
+ *   - 6 bytes SNAP-header
+ *   This results in 39 words or 0x4E bytes or HFS_TYPE.
+ *   Note that if the BUF_SIZE is larger than 0x4E, this surplus is not used.
+ * o The actual frame begins in the 2nd descriptor (which is already implied by the BUF_CNT == 0x3A requirement) and the associated buffer contains at least the 802.3 header, i.e. the 14 bytes representing addressing information and length/type field
+ *
+ *   When the HCF does not encapsulates (i.e. length/type field <= 1500),  no changes are made to descriptors
+ *   or buffers.
+ *
+ *   When the HCF actually encapsulates (i.e. length/type field > 1500), it successively writes, starting at
+ *   offset HFS_ADDR_DEST (0x3A) in the first buffer:
+ *     - the 802.3 addressing information, copied from the begin of the second buffer
+ *     - the frame length, derived from the total length of the individual fragments, corrected for the SNAP
+ *       header length and Type field and ignoring the Destination Address, Source Address and Length field
+ *     - the appropriate snap header (Tunnel or 1042, depending on the value of the type field).
+ *
+ *    The information in the first two descriptors is adjusted accordingly:
+ *     - the first descriptor count is changed from 0x3A to 0x4E (HFS_TYPE), which matches 0x3A + 12 + 2 + 6
+ *     - the second descriptor count is decreased by 12, being the moved addressing information
+ *     - the second descriptor (physical) buffer address is increased by 12.
+ *
+ * When the descriptors are returned by hcf_dma_tx_get, the transformation of the first two descriptors is
+ * undone.
+ *
+ * Under any of the above scenarios, the assert BUF_CNT <= BUF_SIZE must be true for all descriptors
+ * In case of encapsulation, BUF_SIZE of the 1st descriptor is asserted to be at least HFS_TYPE (0x4E), so it is NOT tested.
+ *
+ * Assert fails if
+ * - ifbp has a recognizable out-of-range value.
+ * - tx_cntl has a recognizable out-of-range value.
+ * - NIC interrupts are not disabled while required by parameter action.
+ * - in case encapsulation by the HCF is selected:

+ *       SNAP header of the frame after encapsulation (== 39 words).
+ *     - The second databuffer does not contain at least DA, SA and 'type/length' (==14 bytes or 7 words)

-*.DESCRIPTION
-* The T-field of the LTV-record (provided by the MSF in parameter ltvp) specifies the RID wanted. The RID
-* information identified by the T-field is copied into the V-field.
-* On entry, the L-field specifies the size of the buffer, also called the "Initial DataLength". The L-value
-* includes the size of the T-field, but not the size of the L-field itself.
-* On return, the L-field indicates the number of words actually contained by the Type and Value fields.
-* As the size of the Type field in the LTV-record is included in the "Initial DataLength" of the record, the
-* V-field can contain at most "Initial DataLength" - 1 words of data.
-* Copying stops if either the complete Information is copied or if the number of words indicated by the
-* "Initial DataLength" were copied.  The "Initial DataLength" acts as a safe guard against Configuration
-* Information blocks that have different sizes for different F/W versions, e.g. when later versions support
-* more tallies than earlier versions.
-* If the size of Value field of the RID exceeds the size of the "Initial DataLength" -1, as much data
-* as fits is copied, and an error status of HCF_ERR_LEN is returned.
-*
-* It is the responsibility of the MSF to detect card removal and re-insertion and not call the HCF when the
-* NIC is absent. The MSF cannot, however, timely detect a Card removal if the Card is removed while
-* hcf_get_info is in progress.  Therefore, the HCF performs its own check on Card presence after the read
-* operation of the NIC data.  If the Card is not present or removed during the execution of hcf_get_info,
-* HCF_ERR_NO_NIC is returned and the content of the Data Buffer is unpredictable. This check is not performed
-* in case of the "HCF embedded" pseudo RIDs like CFG_TALLIES.
-*

-* - ifbp has a recognizable out-of-range value.

-* - ltvp is a NULL pointer.
-* - length field of the LTV-record at entry is 0 or 1 or has an excessive value (i.e. exceeds HCF_MAX_LTV).
-* - type field of the LTV-record is invalid.
-*
-*.DIAGRAM
-*	Hcf_get_mb_info copies the contents of the oldest MailBox Info block in the MailBox to PC RAM. If len is
-*	less than the size of the MailBox Info block, only as much as fits in the PC RAM buffer is copied. After
-*	the copying the MailBox Read pointer is updated to point to the next MailBox Info block, hence the
-*	remainder of an "oversized" MailBox Info block is lost. The truncation of the MailBox Info block is NOT
-*	reflected in the return status. Note that hcf_get_info guarantees the length of the PC RAM buffer meets
-*	the minimum requirements of at least 2, so no PC RAM buffer overrun.
-*
-*	Calling hcf_get_mb_info when their is no MailBox Info block available or when there is no MailBox at all,

-*.DESCRIPTION
-* The L-field of the LTV-record (provided by the MSF in parameter ltvp) specifies the size of the buffer.
-* The L-value includes the size of the T-field, but not the size of the L-field.
-* The T- field specifies the RID placed in the V-field by the MSF.
-*
-* Not all CFG-codes can be used for hcf_put_info.  The following CFG-codes are valid for hcf_put_info:
-* o One of the CFG-codes in the group "Network Parameters, Static Configuration Entities"
-* Changes made by hcf_put_info to CFG_codes in this group will not affect the F/W
-* and HCF behavior until hcf_cntl_port( HCF_PORT_ENABLE) is called.
-* o One of the CFG-codes in the group "Network Parameters, Dynamic Configuration Entities"
-* Changes made by hcf_put_info to CFG_codes will affect the F/W and HCF behavior immediately.
-* o CFG_PROG.
-* This code is used to initiate and terminate the process to download data either to
-* volatile or to non-volatile RAM on the NIC as well as for the actual download.
-* o CFG-codes related to the HCF behavior.
-* The related CFG-codes are:
-*  - CFG_REG_MB
-*  - CFG_REG_ASSERT_RTNP
-*  - CFG_REG_INFO_LOG
-*  - CFG_CMD_NIC
-*  - CFG_CMD_DONGLE
-*  - CFG_CMD_HCF
-*  - CFG_NOTIFY
-*
-* All LTV-records "unknown" to the HCF are forwarded to the F/W.
-*
-* Assert fails if
-* - ifbp has a recognizable out-of-range value.
-* - ltvp is a NULL pointer.
-* - hcf_put_info was called without prior call to hcf_connect
-* - type field of the LTV-record is invalid, i.e. neither HCF nor F/W can handle the value.
-* - length field of the LTV-record at entry is less than 1 or exceeds MAX_LTV_SIZE.
-* - registering a MailBox with size less than 60 or a non-aligned buffer address is used.
-* - reentrancy, may be  caused by calling hcf_functions without adequate protection against
-*	NIC interrupts or multi-threading.
-*
-*.DIAGRAM
-*
-*.NOTICE
-*	Remarks:  In case of Hermes Configuration LTVs, the codes for the type are "cleverly" chosen to be
-*	identical to the RID. Hermes Configuration information is copied from the provided data structure into the
-*	Card.
-*	In case of HCF Configuration LTVs, the type values are chosen in a range which does not overlap the

+ *.DESCRIPTION
+ * The L-field of the LTV-record (provided by the MSF in parameter ltvp) specifies the size of the buffer.
+ * The L-value includes the size of the T-field, but not the size of the L-field.
+ * The T- field specifies the RID placed in the V-field by the MSF.
+ *
+ * Not all CFG-codes can be used for hcf_put_info.  The following CFG-codes are valid for hcf_put_info:
+ * o One of the CFG-codes in the group "Network Parameters, Static Configuration Entities"
+ * Changes made by hcf_put_info to CFG_codes in this group will not affect the F/W
+ * and HCF behavior until hcf_cntl_port( HCF_PORT_ENABLE) is called.
+ * o One of the CFG-codes in the group "Network Parameters, Dynamic Configuration Entities"
+ * Changes made by hcf_put_info to CFG_codes will affect the F/W and HCF behavior immediately.
+ * o CFG_PROG.
+ * This code is used to initiate and terminate the process to download data either to
+ * volatile or to non-volatile RAM on the NIC as well as for the actual download.
+ * o CFG-codes related to the HCF behavior.
+ * The related CFG-codes are:
+ *  - CFG_REG_MB
+ *  - CFG_REG_ASSERT_RTNP
+ *  - CFG_REG_INFO_LOG
+ *  - CFG_CMD_NIC
+ *  - CFG_CMD_DONGLE
+ *  - CFG_CMD_HCF
+ *  - CFG_NOTIFY
+ *
+ * All LTV-records "unknown" to the HCF are forwarded to the F/W.
+ *
+ * Assert fails if
+ * - ifbp has a recognizable out-of-range value.
+ * - ltvp is a NULL pointer.
+ * - hcf_put_info was called without prior call to hcf_connect
+ * - type field of the LTV-record is invalid, i.e. neither HCF nor F/W can handle the value.
+ * - length field of the LTV-record at entry is less than 1 or exceeds MAX_LTV_SIZE.
+ * - registering a MailBox with size less than 60 or a non-aligned buffer address is used.
+ * - reentrancy, may be  caused by calling hcf_functions without adequate protection against
+ *   NIC interrupts or multi-threading.
+ *
+ *.DIAGRAM
+ *
+ *.NOTICE
+ *   Remarks:  In case of Hermes Configuration LTVs, the codes for the type are "cleverly" chosen to be
+ *   identical to the RID. Hermes Configuration information is copied from the provided data structure into the

-*				non-USB: specifies the beginning of the data to be obtained (0 corresponds with DestAddr field

-*	HCF_ERR_MIC			message contains an erroneous MIC ( HCF_SUCCESS is reported if HCF_ERR_MIC is already

-* 	HCF_ERR_NO_NIC		NIC removed during data retrieval
-* 	HCF_ERR_DEFUNCT...
-*
-*.DESCRIPTION
-* The Receive Message Function can be executed by the MSF to obtain the Data Info fields of the message that
-* is reported to be available by the Service NIC Function.
-*
-* The Receive Message Function copies the message data available in the Card memory into a buffer structure
-* provided by the MSF.
-* Only data of the message indicated by the Service NIC Function can be obtained.
-* Execution of the Service NIC function may result in the availability of a new message, but it definitely
-* makes the message reported by the preceding Service NIC function, unavailable.
-*
-* in non-USB/non-DMA mode, hcf_rcv_msg starts the copy process at the (non-negative) offset requested by the
-* parameter offset, relative to HFS_ADDR_DEST, e.g offset 0 starts copying from the Destination Address, the
-* very begin of the 802.3 frame message. Offset must either lay within the part of the 802.3 frame as stored
-* by hcf_service_nic in the lookahead buffer or be just behind it, i.e. the first byte not yet read.
-* When offset is within lookahead, data is copied from lookahead.
-* When offset is beyond lookahead, data is read directly from RxFS in NIC with disregard of the actual value
-* of offset
-*
-*.NOTICE:
-* o at entry: look ahead buffer as passed with hcf_service_nic is still accessible and unchanged
-* o at exit: Receive Frame in NIC memory is released
-*
-* Description:
-* Starting at the byte indicated by the Offset value, the bytes are copied from the Data Info
-* Part of the current Receive Frame Structure to the Host memory data buffer structure
-* identified by descp.
-* The maximum value for Offset is the number of characters of the 802.3 frame read into the
-* look ahead buffer by hcf_service_nic (i.e. the look ahead buffer size minus
-* Control and 802.11 fields)
-* If Offset is less than the maximum value, copying starts from the look ahead buffer till the
-* end of that buffer is reached
-* Then (or if the maximum value is specified for Offset), the
-* message is directly copied from NIC memory to Host memory.
-* If an invalid (i.e. too large) offset is specified, an assert catches but the buffer contents are
-* undefined.
-* Copying stops if either:
-* o the end of the 802.3 frame is reached
-* o the Descriptor with a NULL pointer in the next_desc_addr field is reached
-*
-* When the copying stops, the receiver is ack'ed, thus freeing the NIC memory where the frame is stored
-* As a consequence, hcf_rcv_msg can only be called once for any particular Rx frame.
-*
-* For the time being (PCI Bus mastering not yet supported), only the following fields of each
-* of the descriptors in the descriptor list must be set by the MSF:
-* o buf_cntl.buf_dim[1]
-* o *next_desc_addr
-* o *buf_addr
-* At return from hcf_rcv_msg, the field buf_cntl.buf_dim[0] of the used Descriptors reflects
-* the number of bytes in the buffer corresponding with the Descriptor.
-* On the last used Descriptor, buf_cntl.buf_dim[0] is less or equal to buf_cntl.buf_dim[1].
-* On all preceding Descriptors buf_cntl.buf_dim[0] is equal to buf_cntl.buf_dim[1].
-* On all succeeding (unused) Descriptors, buf_cntl.buf_dim[0] is zero.
-* Note: this I/F is based on the assumptions how the I/F needed for PCI Bus mastering will
-* be, so it may change.
-*
-* The most likely handling of HCF_ERR_NO_NIC by the MSF is to drop the already copied
-* data as elegantly as possible under the constraints and requirements posed by the (N)OS.
-* If no received Frame Structure is pending, "Success" rather than "Read error" is returned.
-* This error constitutes a logic flaw in the MSF
-* The HCF can only catch a minority of this
-* type of errors
-* Based on consistency ideas, the HCF catches none of these errors.
-*
-* Assert fails if
-* - ifbp has a recognizable out-of-range value
-* - there is no unacknowledged Rx-message available
-* - offset is out of range (outside look ahead buffer)
-* - descp is a NULL pointer
-* - any of the descriptors is not double word aligned
-* - reentrancy, may be  caused by calling hcf_functions without adequate protection
-* 	against NIC interrupts or multi-threading.
-* - Interrupts are enabled.
-*
-*.DIAGRAM
-*
-*.NOTICE
-* - by using unsigned int as type for offset, no need to worry about negative offsets
-* - Asserting on being enabled/present is superfluous, since a non-zero IFB_lal implies that hcf_service_nic
-*   was called and detected a Rx-message. A zero IFB_lal will set the BUF_CNT field of at least the first
-*   descriptor to zero.

+ * parameter offset, relative to HFS_ADDR_DEST, e.g offset 0 starts copying from the Destination Address, the
+ * very begin of the 802.3 frame message. Offset must either lay within the part of the 802.3 frame as stored
+ * by hcf_service_nic in the lookahead buffer or be just behind it, i.e. the first byte not yet read.
+ * When offset is within lookahead, data is copied from lookahead.
+ * When offset is beyond lookahead, data is read directly from RxFS in NIC with disregard of the actual value
+ * of offset
+ *
+ *.NOTICE:
+ * o at entry: look ahead buffer as passed with hcf_service_nic is still accessible and unchanged
+ * o at exit: Receive Frame in NIC memory is released
+ *
+ * Description:
+ * Starting at the byte indicated by the Offset value, the bytes are copied from the Data Info
+ * Part of the current Receive Frame Structure to the Host memory data buffer structure
+ * identified by descp.
+ * The maximum value for Offset is the number of characters of the 802.3 frame read into the
+ * look ahead buffer by hcf_service_nic (i.e. the look ahead buffer size minus
+ * Control and 802.11 fields)
+ * If Offset is less than the maximum value, copying starts from the look ahead buffer till the
+ * end of that buffer is reached
+ * Then (or if the maximum value is specified for Offset), the
+ * message is directly copied from NIC memory to Host memory.
+ * If an invalid (i.e. too large) offset is specified, an assert catches but the buffer contents are
+ * undefined.
+ * Copying stops if either:
+ * o the end of the 802.3 frame is reached
+ * o the Descriptor with a NULL pointer in the next_desc_addr field is reached
+ *
+ * When the copying stops, the receiver is ack'ed, thus freeing the NIC memory where the frame is stored
+ * As a consequence, hcf_rcv_msg can only be called once for any particular Rx frame.
+ *
+ * For the time being (PCI Bus mastering not yet supported), only the following fields of each
+ * of the descriptors in the descriptor list must be set by the MSF:
+ * o buf_cntl.buf_dim[1]
+ * o *next_desc_addr
+ * o *buf_addr
+ * At return from hcf_rcv_msg, the field buf_cntl.buf_dim[0] of the used Descriptors reflects
+ * the number of bytes in the buffer corresponding with the Descriptor.
+ * On the last used Descriptor, buf_cntl.buf_dim[0] is less or equal to buf_cntl.buf_dim[1].
+ * On all preceding Descriptors buf_cntl.buf_dim[0] is equal to buf_cntl.buf_dim[1].
+ * On all succeeding (unused) Descriptors, buf_cntl.buf_dim[0] is zero.
+ * Note: this I/F is based on the assumptions how the I/F needed for PCI Bus mastering will
+ * be, so it may change.
+ *
+ * The most likely handling of HCF_ERR_NO_NIC by the MSF is to drop the already copied
+ * data as elegantly as possible under the constraints and requirements posed by the (N)OS.
+ * If no received Frame Structure is pending, "Success" rather than "Read error" is returned.
+ * This error constitutes a logic flaw in the MSF
+ * The HCF can only catch a minority of this
+ * type of errors
+ * Based on consistency ideas, the HCF catches none of these errors.
+ *
+ * Assert fails if
+ * - ifbp has a recognizable out-of-range value
+ * - there is no unacknowledged Rx-message available
+ * - offset is out of range (outside look ahead buffer)
+ * - descp is a NULL pointer
+ * - any of the descriptors is not double word aligned
+ * - reentrancy, may be  caused by calling hcf_functions without adequate protection
+ *   against NIC interrupts or multi-threading.
+ * - Interrupts are enabled.
+ *
+ *.DIAGRAM
+ *
+ *.NOTICE
+ * - by using unsigned int as type for offset, no need to worry about negative offsets
+ * - Asserting on being enabled/present is superfluous, since a non-zero IFB_lal implies that hcf_service_nic
+ *   was called and detected a Rx-message. A zero IFB_lal will set the BUF_CNT field of at least the first
+ *   descriptor to zero.

-*
-*.DESCRIPTION:
-* The Send Message Function embodies 2 functions:
-* o transfers a message (including MAC header) from the provided buffer structure in Host memory to the Transmit
-* Frame Structure (TxFS) in NIC memory.
-* o Issue a send command to the F/W to actually transmit the contents of the TxFS.
-*
-* Control is based on the Resource Indicator IFB_RscInd.
-* The Resource Indicator is maintained by the HCF and should only be interpreted but not changed by the MSF.
-* The MSF must check IFB_RscInd to be non-zero before executing the call to the Send Message Function.
-* When no resources are available, the MSF must handle the queuing of the Transmit frame and check the
-* Resource Indicator periodically after calling hcf_service_nic.
-*
-* The Send Message Functions transfers a message to NIC memory when it is called with a non-NULL descp.
-* Before the Send Message Function is invoked this way, the Resource Indicator (IFB_RscInd) must be checked.
-* If the Resource is not available, Send Message Function execution must be postponed until after processing of
-* a next hcf_service_nic it appears that the Resource has become available.
-* The message is copied from the buffer structure identified by descp to the NIC.
-* Copying stops if a NULL pointer in the next_desc_addr field is reached.
-* Hcf_send_msg does not check for transmit buffer overflow, because the F/W does this protection.
-* In case of a transmit buffer overflow, the surplus which does not fit in the buffer is simply dropped.
-*
-* The Send Message Function activates the F/W to actually send the message to the medium when the
-* HFS_TX_CNTL_TX_DELAY bit of the tx_cntl parameter is not set.
-* If the descp parameter of the current call is non-NULL, the message as represented by descp is send.
-* If the descp parameter of the current call is NULL, and if the preceding call of the Send Message Function had
-* a non-NULL descp and the preceding call had the HFS_TX_CNTL_TX_DELAY bit of tx_cntl set, then the message as
-* represented by the descp of the preceding call is send.
-*
-* Hcf_send_msg supports encapsulation (see HCF_ENCAP) of Ethernet-II frames.
-* An Ethernet-II frame is transferred to the Transmit Frame structure as an 802.3 frame.
-* Hcf_send_msg distinguishes between an 802.3 and an Ethernet-II frame by looking at the data length/type field
-* of the frame. If this field contains a value larger than 1514, the frame is considered to be an Ethernet-II
-* frame, otherwise it is treated as an 802.3 frame.
-* To ease implementation of the HCF, this type/type field must be located in the first descriptor structure,
-* i.e. the 1st fragment must have a size of at least 14 (to contain DestAddr, SrcAddr and Len/Type field).
-* An Ethernet-II frame is encapsulated by inserting a SNAP header between the addressing information and the
-* type field.  This insertion is transparent for the MSF.
-* The HCF contains a fixed table that stores a number of types. If the value specified by the type/type field
-* occurs in this table, Bridge Tunnel Encapsulation is used, otherwise RFC1042 encapsulation is used.
-* Bridge Tunnel uses	AA AA 03 00 00 F8 as SNAP header,
-* RFC1042 uses	AA AA 03 00 00 00 as SNAP header.
-* The table currently contains:
-* 0 0x80F3	AppleTalk Address Resolution Protocol (AARP)
-* 0 0x8137	IPX
-*
-* The algorithm to distinguish between 802.3 and Ethernet-II frames limits the maximum length for frames of
-* 802.3 frames to 1514 bytes.
-* Encapsulation can be suppressed by means of the system constant HCF_ENCAP, e.g. to support proprietary
-* protocols with 802.3 like frames with a size larger than 1514 bytes.
-*
-* In case the HCF encapsulates the frame, the number of bytes that is actually transmitted is determined by the
-* cumulative value of the buf_cntl.buf_dim[0] fields.
-* In case the HCF does not encapsulate the frame, the number of bytes that is actually transmitted is not
-* determined by the cumulative value of the buf_cntl.buf_dim[DESC_CNTL_CNT] fields of the desc_strct's but by
-* the Length field of the 802.3 frame.
-* If there is a conflict between the cumulative value of the buf_cntl.buf_dim[0] fields and the
-* 802.3 Length field the 802.3 Length field determines the number of bytes actually transmitted by the NIC while
-* the cumulative value of the buf_cntl.buf_dim[0] fields determines the position of the MIC, hence a mismatch
-* will result in MIC errors on the Receiving side.
-* Currently this problem is flagged on the Transmit side by an Assert.
-* The following fields of each of the descriptors in the descriptor list must be set by the MSF:
-* o buf_cntl.buf_dim[0]
-* o *next_desc_addr
-* o *buf_addr
-*
-* All bits of the tx_cntl parameter except HFS_TX_CNTL_TX_DELAY and the HCF_PORT# bits are passed to the F/W via
-* the HFS_TX_CNTL field of the TxFS.
-*
-* Note that hcf_send_msg does not detect NIC absence.  The MSF is supposed to have its own -platform dependent-
-* way to recognize card removal/insertion.
-* The total system must be robust against card removal and there is no principal difference between card removal
-* just after hcf_send_msg returns but before the actual transmission took place or sometime earlier.
-*
-* Assert fails if
-* - ifbp has a recognizable out-of-range value
-* - descp is a NULL pointer
-* - no resources for PIF available.
-* - Interrupts are enabled.
-* - reentrancy, may be  caused by calling hcf_functions without adequate protection
-*	against NIC interrupts or multi-threading.
-*
-*.DIAGRAM
-*4:	for the normal case (i.e. no HFS_TX_CNTL_TX_DELAY option active), a fid is acquired via the
-*	routine get_fid.  If no FID is acquired, the remainder is skipped without an error notification.  After
-*	all, the MSF is not supposed to call hcf_send_msg when no Resource is available.
-*7:	The ControlField of the TxFS is written.  Since put_frag can only return the fatal Defunct or "No NIC", the
-*	return status can be ignored because when it fails, cmd_wait will fail as well.  (see also the note on the
-*	need for a return code below).
-*	Note that HFS_TX_CNTL has different values for H-I, H-I/SSN and H-II and HFS_ADDR_DEST has different
-*	values for H-I (regardless of SSN) and H-II.
-*	By writing 17, 1 or 2 ( implying 16, 0 or 1 garbage word after HFS_TX_CNTL) the BAP just gets to
-*	HFS_ADDR_DEST for H-I, H-I/SSN and H-II respectively.
-*10: if neither encapsulation nor MIC calculation is needed, splitting the first fragment in two does not
-*	really help but it makes the flow easier to follow to do not optimize on this difference
-*
-*	hcf_send_msg checks whether the frame is an Ethernet-II rather than an "official" 802.3 frame.
-*	The E-II check is based on the length/type field in the MAC header. If this field has a value larger than
-*	1500, E-II is assumed. The implementation of this test fails if the length/type field is not in the first
-*	descriptor.  If E-II is recognized, a SNAP header is inserted. This SNAP header represents either RFC1042
-*	or Bridge-Tunnel encapsulation, depending on the return status of the support routine hcf_encap.
-*
-*.NOTICE
-*	hcf_send_msg leaves the responsibility to only send messages on enabled ports at the MSF level.
-*	This is considered the strategy which is sufficiently adequate for all "robust" MSFs, have the least
-*	processor utilization and being still acceptable robust at the WCI !!!!!
-*
-*	hcf_send_msg does not NEED a return value to report NIC absence or removal during the execution of
-*	hcf_send_msg(), because the MSF and higher layers must be able to cope anyway with the NIC being removed
-*	after a successful completion of hcf_send_msg() but before the actual transmission took place.
-*	To accommodate user expectations the current implementation does report NIC absence.
-*	Defunct blocks all NIC access and will (also) be reported on a number of other calls.
-*
-*	hcf_send_msg does not check for transmit buffer overflow because the Hermes does this protection.
-*	In case of a transmit buffer overflow, the surplus which does not fit in the buffer is simply dropped.
-*	Note that this possibly results in the transmission of incomplete frames.
-*
-*	After some deliberation with F/W team, it is decided that - being in the twilight zone of not knowing
-*	whether the problem at hand is an MSF bug, HCF buf, F/W bug, H/W malfunction or even something else - there
-*	is no "best thing to do" in case of a failing send, hence the HCF considers the TxFID ownership to be taken
-*	over by the F/W and hopes for an Allocate event in due time

+ * the cumulative value of the buf_cntl.buf_dim[0] fields determines the position of the MIC, hence a mismatch
+ * will result in MIC errors on the Receiving side.
+ * Currently this problem is flagged on the Transmit side by an Assert.
+ * The following fields of each of the descriptors in the descriptor list must be set by the MSF:
+ * o buf_cntl.buf_dim[0]
+ * o *next_desc_addr
+ * o *buf_addr
+ *
+ * All bits of the tx_cntl parameter except HFS_TX_CNTL_TX_DELAY and the HCF_PORT# bits are passed to the F/W via
+ * the HFS_TX_CNTL field of the TxFS.
+ *
+ * Note that hcf_send_msg does not detect NIC absence.  The MSF is supposed to have its own -platform dependent-
+ * way to recognize card removal/insertion.
+ * The total system must be robust against card removal and there is no principal difference between card removal
+ * just after hcf_send_msg returns but before the actual transmission took place or sometime earlier.
+ *
+ * Assert fails if
+ * - ifbp has a recognizable out-of-range value
+ * - descp is a NULL pointer
+ * - no resources for PIF available.
+ * - Interrupts are enabled.
+ * - reentrancy, may be  caused by calling hcf_functions without adequate protection
+ *   against NIC interrupts or multi-threading.
+ *
+ *.DIAGRAM
+ *4: for the normal case (i.e. no HFS_TX_CNTL_TX_DELAY option active), a fid is acquired via the
+ *   routine get_fid.  If no FID is acquired, the remainder is skipped without an error notification.  After
+ *   all, the MSF is not supposed to call hcf_send_msg when no Resource is available.
+ *7: The ControlField of the TxFS is written.  Since put_frag can only return the fatal Defunct or "No NIC", the
+ *   return status can be ignored because when it fails, cmd_wait will fail as well.  (see also the note on the
+ *   need for a return code below).
+ *   Note that HFS_TX_CNTL has different values for H-I, H-I/WPA and H-II and HFS_ADDR_DEST has different
+ *   values for H-I (regardless of WPA) and H-II.
+ *   By writing 17, 1 or 2 ( implying 16, 0 or 1 garbage word after HFS_TX_CNTL) the BAP just gets to
+ *   HFS_ADDR_DEST for H-I, H-I/WPA and H-II respectively.
+ *10: if neither encapsulation nor MIC calculation is needed, splitting the first fragment in two does not
+ *   really help but it makes the flow easier to follow to do not optimize on this difference
+ *
+ *   hcf_send_msg checks whether the frame is an Ethernet-II rather than an "official" 802.3 frame.
+ *   The E-II check is based on the length/type field in the MAC header. If this field has a value larger than
+ *   1500, E-II is assumed. The implementation of this test fails if the length/type field is not in the first
+ *   descriptor.  If E-II is recognized, a SNAP header is inserted. This SNAP header represents either RFC1042
+ *   or Bridge-Tunnel encapsulation, depending on the return status of the support routine hcf_encap.
+ *
+ *.NOTICE
+ *   hcf_send_msg leaves the responsibility to only send messages on enabled ports at the MSF level.
+ *   This is considered the strategy which is sufficiently adequate for all "robust" MSFs, have the least
+ *   processor utilization and being still acceptable robust at the WCI !!!!!
+ *
+ *   hcf_send_msg does not NEED a return value to report NIC absence or removal during the execution of
+ *   hcf_send_msg(), because the MSF and higher layers must be able to cope anyway with the NIC being removed
+ *   after a successful completion of hcf_send_msg() but before the actual transmission took place.
+ *   To accommodate user expectations the current implementation does report NIC absence.
+ *   Defunct blocks all NIC access and will (also) be reported on a number of other calls.
+ *
+ *   hcf_send_msg does not check for transmit buffer overflow because the Hermes does this protection.
+ *   In case of a transmit buffer overflow, the surplus which does not fit in the buffer is simply dropped.
+ *   Note that this possibly results in the transmission of incomplete frames.
+ *
+ *   After some deliberation with F/W team, it is decided that - being in the twilight zone of not knowing
+ *   whether the problem at hand is an MSF bug, HCF buf, F/W bug, H/W malfunction or even something else - there
+ *   is no "best thing to do" in case of a failing send, hence the HCF considers the TxFID ownership to be taken
+ *   over by the F/W and hopes for an Allocate event in due time

 * **Rx Buffer free strategy
-*	When hcf_service_nic reports the availability of a non-DMA message, the MSF can access that message by
-*	means of hcf_rcv_msg. It must be prevented that the LAN Controller writes new data in the NIC buffer
-*	before the MSF is finished with the current message. The NIC buffer is returned to the LAN Controller

-*	 - hcf_rcv_msg is called or

-*	It can be reasoned that hcf_action( INT_ON ) should not be given before the MSF has completely processed
-*	a reported Rx-frame. The reason is that the INT_ON action is guaranteed to cause a (Rx-)interrupt (the

-*	interrupt will cause hcf_service_nic to be called, which will cause the ack-ing of the "last" Rx-event

-*.DESCRIPTION
-* calibrates the S/W protection counter against the Hermes Timer tick
-* IFB_TickIni is the value used to initialize the S/W protection counter such that the expiration period
-* more or less independent of the processor speed. If IFB_TickIni is not yet calibrated, it is done now.
-* This calibration is "reasonably" accurate because the Hermes is in a quiet state as a result of the

-*
-*.DIAGRAM
-*
-*1:	IFB_TickIni is initialized at INI_TICK_INI by hcf_connect. If calibrate succeeds, IFB_TickIni is
-*	guaranteed to be changed. As a consequence there will be only 1 shot at calibration (regardless of the

-*4:	Ack everything except HREG_EV_SLEEP_REQ. It is very likely that an Alloc event is pending and

-*10: Calibrate the S/W time-out protection mechanism by calling calibrate(). Note that possible errors
-*	in the calibration process are nor reported by init but will show up via the defunct mechanism in
-*	subsequent hcf-calls.
-*14: usb_check_comp() is called to have the minimal visual clutter for the legacy H-I USB dongle
-*	compatibility check.
-*16: The following configuration management related information is retrieved from the NIC:
-*	 - HSI supplier
-*	 - F/W Identity
-*	 - F/W supplier
-*	 if appropriate:
-*	 - PRI Identity
-*	 - PRI supplier
-*	 appropriate means on H-I: always
-*	 and on H-II if F/W supplier reflects a primary (i.e. only after an Hermes Reset or Init
-*	 command).
-*	 QUESTION ;? !!!!!! should, For each of the above RIDs the Endianess is converted to native Endianess.
-*	 Only the return code of the first hcf_get_info is used. All hcf_get_info calls are made, regardless of
-*	 the success or failure of the 1st hcf_get_info. The assumptions are:
-*	  - if any call fails, they all fail, so remembering the result of the 1st call is adequate
-*	  - a failing call will overwrite the L-field with a 0x0000 value, which services both as an
-*		error indication for the values cached in the IFB as making mmd_check_comp fail.
-*	 In case of H-I, when getting the F/W identity fails, the F/W is assumed to be H-I AP F/W pre-dating
-*	 version 9.0 and the F/W Identity and Supplier are faked accordingly.
-*	 In case of H-II, the Primary, Station and AP Identity are merged into a single F/W Identity.
-*	 The same applies to the Supplier information. As a consequence the PRI information can no longer be
-*	 retrieved when a Tertiary runs. To accommodate MSFs and Utilities who depend on PRI information being
-*	 available at any time, this information is cached in the IFB. In this cache the generic "F/W" value of
-*	 the typ-fields is overwritten with the specific (legacy) "PRI" values. To actually re-route the (legacy)
-*	 PRI request via hcf_get_info, the xxxx-table must be set.  In case of H-I, this caching, modifying and
-*	 re-routing is not needed because PRI information is always available directly from the NIC. For
-*	 consistency the caching fields in the IFB are filled with the PRI information anyway.
-*18: mdd_check_comp() is called to check the Supplier Variant and Range of the Host-S/W I/F (HSI) and the
-*	Primary Firmware Variant and Range against the Top and Bottom level supported by this HCF.  If either of
-*	these tests fails, the CARD_STAT_INCOMP_PRI bit of IFB_CardStat is set
-*	Note: There should always be a primary except during production, so this makes the HCF in its current form
-*	unsuitable for manufacturing test systems like the FTS. This can be remedied by an adding a test like
-*	ifbp->IFB_PRISup.id == COMP_ID_PRI
-*20: In case there is Tertiary F/W and this F/W is Station F/W, the Supplier Variant and Range of the Station
-*	Firmware function as retrieved from the Hermes is checked against the Top and Bottom level supported by
-*	this HCF.
-*	Note: ;? the tertiary F/W compatibility checks could be moved to the DHF, which already has checked the
-*	CFI and MFI compatibility of the image with the NIC before the image was downloaded.
-*28: In case of non-Primary F/W: allocates and acknowledge a (TX or Notify) FID and allocates without
-*	acknowledge another (TX or Notify) FID (the so-called 1.5 alloc scheme) with the following steps:
-*	- execute the allocate command by calling cmd_exe
-*	- wait till either the alloc event or a time-out occurs
-*	- regardless whether the alloc event occurs, call get_fid to
-*	  - read the FID and save it in IFB_RscInd to be used as "spare FID"
-*	  - acknowledge the alloc event
-*	  - do another "half" allocate to complete the "1.5 Alloc scheme"

-*
-*.SUBMODULE		int setup_bap( IFBP ifbp, hcf_16 fid, int offset, int type )
-*.PURPOSE		set up data access to NIC RAM via BAP_1.
-*
-*.ARGUMENTS
-*	ifbp			address of I/F Block
-*	fid				FID/RID
-*	offset			!!even!! offset in FID/RID
-*	type			IO_IN, IO_OUT
-*
-*.RETURNS
-*	HCF_SUCCESS					O.K

-*	HCF_ERR_DEFUNCT_TIME_OUT	Fatal malfunction detected
-*	HCF_ERR_DEFUNCT_.....		if and only if IFB_DefunctStat <> 0
-*
-*.DESCRIPTION
-*
-* A non-zero return status indicates:
-* - the NIC is considered nonoperational, e.g. due to a time-out of some Hermes activity in the past
-* - BAP_1 could not properly be initialized
-* - the card is removed before completion of the data transfer
-* In all other cases, a zero is returned.
-* BAP Initialization failure indicates an H/W error which is very likely to signal complete H/W failure.
-* Once a BAP Initialization failure has occurred all subsequent interactions with the Hermes will return a
-* "defunct" status till the Hermes is re-initialized by means of an hcf_connect.
-*
-* A BAP is a set of registers (Offset, Select and Data) offering read/write access to a particular FID or
-* RID. This access is based on a auto-increment feature.
-* There are two BAPs but these days the HCF uses only BAP_1 and leaves BAP_0 to the PCI Busmastering H/W.
-*
-* The BAP-mechanism is based on the Busy bit in the Offset register (see the Hermes definition). The waiting
-* for Busy must occur between writing the Offset register and accessing the Data register. The
-* implementation to wait for the Busy bit drop after each write to the Offset register, implies that the
-* requirement that the Busy bit is low  before the Select register is written, is automatically met.
-* BAP-setup may be time consuming (e.g. 380 usec for large offsets occurs frequently). The wait for Busy bit
-* drop is protected by a loop counter, which is initialized with IFB_TickIni, which is calibrated in init.
-*
-* The NIC I/F is optimized for word transfer and can only handle word transfer at a word boundary in NIC
-* RAM. The intended solution for transfer of a single byte has multiple H/W flaws. There have been different
-* S/W Workaround strategies. RID access is hcf_16 based by "nature", so no byte access problems.  For Tx/Rx
-* FID access,  the byte logic became obsolete by absorbing it in the double word oriented nature of the MIC
-* feature.
-*
-*
-*.DIAGRAM
-*
-*2:	the test on rc checks whether the HCF went into "defunct" mode ( e.g. BAP initialization or a call to
-*	cmd_wait did ever fail).
-*4:	the select register and offset register are set
-*	the offset register is monitored till a successful condition (no busy bit) is detected or till the
-*	(calibrated) protection counter expires
-*	If the counter expires, this is reflected in IFB_DefunctStat, so all subsequent calls to setup_bap fail
-*	immediately ( see 2)
-*6:	initialization of the carry as used by pet/get_frag
-*8:	HREG_OFFSET_ERR is ignored as error because:
-*	 a: the Hermes is robust against it
-*	 b: it is not known what causes it (probably a bug), hence no strategy can be specified which level is
-*		to handle this error in which way. In the past, it could be induced by the MSF level, e.g. by calling
-*		hcf_rcv_msg while there was no Rx-FID available. Since this is an MSF-error which is caught by ASSERT,
-*		there is no run-time action required by the HCF.
-*	Lumping the Offset error in with the Busy bit error, as has been done in the past turns out to be a
-*	disaster or a life saver, just depending on what the cause of the error is. Since no prediction can be
-*	done about the future, it is "felt" to be the best strategy to ignore this error. One day the code was

-*	//	ignore HREG_OFFSET_ERR, someone, supposedly the MSF programmer ;) made a bug. Since we don't know

+ * Workaround for problem described in chip errata 2:
+ *
+ * Sometimes interrupts are not generated when ATL (not INT?) completion occurs.
+ * One solution suggested in the errata is to use SOF interrupts _instead_of_
+ * ATL done interrupts (the "instead of" might be important since it seems
+ * enabling ATL interrupts also causes the chip to sometimes - rarely - "forget"
+ * to set the PTD's done bit in addition to not generating an interrupt!).
+ *
+ * So if we use SOF + ATL interrupts, we sometimes get stale PTDs since their
+ * done bit is not being set. This is bad - it blocks the endpoint until reboot.
+ *
+ * If we use SOF interrupts only, we get latency between ptd completion and the
+ * actual handling. This is very noticeable in testusb runs which takes several
+ * minutes longer without ATL interrupts.
+ *
+ * A better solution is to run the code below every SLOT_CHECK_PERIOD ms. If it
+ * finds active ATL slots which are older than SLOT_TIMEOUT ms, it checks the
+ * slot's ACTIVE and VALID bits. If these are not set, the ptd is considered
+ * completed and its done map bit is set.
+ *
+ * The values of SLOT_TIMEOUT and SLOT_CHECK_PERIOD have been arbitrarily chosen
+ * not to cause too much lag when this HW bug occurs, while still hopefully
+ * ensuring that the check does not falsely trigger.

+ *
+ * Obviously, we can't solve an NP complete problem to find the minimum worst
+ * case scenario.  Instead, we come up with an estimate that is no less than
+ * the worst case bandwidth used for any one microframe, but may be an
+ * over-estimate.
+ *
+ * We walk the requirements for each endpoint by interval, starting with the
+ * smallest interval, and place packets in the schedule where there is only one
+ * possible way to schedule packets for that interval.  In order to simplify
+ * this algorithm, we record the largest max packet size for each interval, and
+ * assume all packets will be that size.
+ *
+ * For interval 0, we obviously must schedule all packets for each interval.
+ * The bandwidth for interval 0 is just the amount of data to be transmitted
+ * (the sum of all max ESIT payload sizes, plus any overhead per packet times
+ * the number of packets).
+ *
+ * For interval 1, we have two possible microframes to schedule those packets
+ * in.  For this algorithm, if we can schedule the same number of packets for
+ * each possible scheduling opportunity (each microframe), we will do so.  The
+ * remaining number of packets will be saved to be transmitted in the gaps in
+ * the next interval's scheduling sequence.
+ *
+ * As we move those remaining packets to be scheduled with interval 2 packets,
+ * we have to double the number of remaining packets to transmit.  This is
+ * because the intervals are actually powers of 2, and we would be transmitting
+ * the previous interval's packets twice in this interval.  We also have to be
+ * sure that when we look at the largest max packet size for this interval, we
+ * also look at the largest max packet size for the remaining packets and take
+ * the greater of the two.
+ *
+ * The algorithm continues to evenly distribute packets in each scheduling
+ * opportunity, and push the remaining packets out, until we get to the last
+ * interval.  Then those packets and their associated overhead are just added

+ * DOC: AP support for powersaving clients
+ *
+ * In order to implement AP and P2P GO modes, mac80211 has support for
+ * client powersaving, both "legacy" PS (PS-Poll/null data) and uAPSD.
+ * There currently is no support for sAPSD.
+ *
+ * There is one assumption that mac80211 makes, namely that a client
+ * will not poll with PS-Poll and trigger with uAPSD at the same time.
+ * Both are supported, and both can be used by the same client, but
+ * they can't be used concurrently by the same client. This simplifies
+ * the driver code.
+ *
+ * The first thing to keep in mind is that there is a flag for complete
+ * driver implementation: %IEEE80211_HW_AP_LINK_PS. If this flag is set,
+ * mac80211 expects the driver to handle most of the state machine for
+ * powersaving clients and will ignore the PM bit in incoming frames.
+ * Drivers then use ieee80211_sta_ps_transition() to inform mac80211 of
+ * stations' powersave transitions. In this mode, mac80211 also doesn't
+ * handle PS-Poll/uAPSD.
+ *
+ * In the mode without %IEEE80211_HW_AP_LINK_PS, mac80211 will check the
+ * PM bit in incoming frames for client powersave transitions. When a
+ * station goes to sleep, we will stop transmitting to it. There is,
+ * however, a race condition: a station might go to sleep while there is
+ * data buffered on hardware queues. If the device has support for this
+ * it will reject frames, and the driver should give the frames back to
+ * mac80211 with the %IEEE80211_TX_STAT_TX_FILTERED flag set which will
+ * cause mac80211 to retry the frame when the station wakes up. The
+ * driver is also notified of powersave transitions by calling its
+ * @sta_notify callback.
+ *
+ * When the station is asleep, it has three choices: it can wake up,
+ * it can PS-Poll, or it can possibly start a uAPSD service period.
+ * Waking up is implemented by simply transmitting all buffered (and
+ * filtered) frames to the station. This is the easiest case. When
+ * the station sends a PS-Poll or a uAPSD trigger frame, mac80211
+ * will inform the driver of this with the @allow_buffered_frames
+ * callback; this callback is optional. mac80211 will then transmit
+ * the frames as usual and set the %IEEE80211_TX_CTL_POLL_RESPONSE
+ * on each frame. The last frame in the service period (or the only
+ * response to a PS-Poll) also has %IEEE80211_TX_STATUS_EOSP set to
+ * indicate that it ends the service period; as this frame must have
+ * TX status report it also sets %IEEE80211_TX_CTL_REQ_TX_STATUS.
+ * When TX status is reported for this frame, the service period is
+ * marked has having ended and a new one can be started by the peer.
+ *
+ * Another race condition can happen on some devices like iwlwifi
+ * when there are frames queued for the station and it wakes up
+ * or polls; the frames that are already queued could end up being
+ * transmitted first instead, causing reordering and/or wrong
+ * processing of the EOSP. The cause is that allowing frames to be
+ * transmitted to a certain station is out-of-band communication to
+ * the device. To allow this problem to be solved, the driver can
+ * call ieee80211_sta_block_awake() if frames are buffered when it
+ * is notified that the station went to sleep. When all these frames
+ * have been filtered (see above), it must call the function again
+ * to indicate that the station is no longer blocked.
+ *
+ * If the driver buffers frames in the driver for aggregation in any
+ * way, it must use the ieee80211_sta_set_buffered() call when it is
+ * notified of the station going to sleep to inform mac80211 of any
+ * TIDs that have frames buffered. Note that when a station wakes up
+ * this information is reset (hence the requirement to call it when
+ * informed of the station going to sleep). Then, when a service
+ * period starts for any reason, @release_buffered_frames is called
+ * with the number of frames to be released and which TIDs they are
+ * to come from. In this case, the driver is responsible for setting
+ * the EOSP (for uAPSD) and MORE_DATA bits in the released frames,
+ * to help the @more_data paramter is passed to tell the driver if
+ * there is more data on other TIDs -- the TIDs to release frames
+ * from are ignored since mac80211 doesn't know how many frames the
+ * buffers for those TIDs contain.
+ *
+ * If the driver also implement GO mode, where absence periods may
+ * shorten service periods (or abort PS-Poll responses), it must
+ * filter those response frames except in the case of frames that
+ * are buffered in the driver -- those must remain buffered to avoid
+ * reordering. Because it is possible that no frames are released
+ * in this case, the driver must call ieee80211_sta_eosp_irqsafe()
+ * to indicate to mac80211 that the service period ended anyway.
+ *
+ * Finally, if frames from multiple TIDs are released from mac80211
+ * but the driver might reorder them, it must clear & set the flags
+ * appropriately (only the last frame may have %IEEE80211_TX_STATUS_EOSP)
+ * and also take care of the EOSP and MORE_DATA bits in the frame.
+ * The driver may also use ieee80211_sta_eosp_irqsafe() in this case.
