+                                  Any attempt to change BL using VBIOS function or enable VariBri from PP table is not effective since ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==0;

+                                  When it's set to a non-zero frequency, the BackLight is controlled by GPU (SW) in one of two ways below:
+                                  1. SW uses the GPU BL PWM output to control the BL, in chis case, this non-zero frequency determines what freq GPU should use;
+                                  VBIOS will set up proper PWM frequency and ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1,as the result,
+                                  Changing BL using VBIOS function is functional in both driver and non-driver present environment; 
+                                  and enabling VariBri under the driver environment from PP table is optional.
+
+                                  2. SW uses other means to control BL (like DPCD),this non-zero frequency serves as a flag only indicating
+                                  that BL control from GPU is expected.
+                                  VBIOS will NOT set up PWM frequency but make ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1
+                                  Changing BL using VBIOS function could be functional in both driver and non-driver present environment,but

 /*
- * Original Media Tablet 10.6 inch report descriptor.
- *
- * There are at least two versions of this model in the wild. They are
- * represented by Genius G-Pen M609 (older version) and Genius G-Pen M609X
- * (newer version).
- *
- * Both versions have the usual pen with two barrel buttons and two
- * identical wheels with center buttons in the top corners of the tablet
- * base. They also have buttons on the top, between the wheels, for
- * selecting the wheels' functions and wide/standard mode. In the wide mode
- * the whole working surface is sensed, in the standard mode a narrower area
- * is sensed, but the logical report extents remain the same. These modes
- * correspond roughly to 16:9 and 4:3 aspect ratios respectively.
- *
- * The older version has three wheel function buttons ("scroll", "zoom" and
- * "volume") and two separate buttons for wide and standard mode. The newer
- * version has four wheel function buttons (plus "brush") and only one
- * button is used for selecting wide/standard mode. So, the total number of
- * buttons remains the same, but one of the mode buttons is repurposed as a
- * wheels' function button in the newer version.
- *
- * The wheel functions are:
- * scroll   - the wheels act as scroll wheels, the center buttons switch
- *            between vertical and horizontal scrolling;
- * zoom     - the wheels zoom in/out, the buttons supposedly reset to 100%;
- * volume   - the wheels control the sound volume, the buttons mute;
- * brush    - the wheels are supposed to control brush width in a graphics
- *            editor, the buttons do nothing.
- *
- * Below is the newer version's report descriptor. It may very well be that
- * the older version's descriptor is different and thus it won't be
- * supported.
- *
- * The mouse report (ID 1) only uses the wheel field for reporting the tablet
- * wheels' scroll mode. The keyboard report (ID 13) is used to report the
- * wheels' zoom and brush control functions as key presses. The report ID 12
- * is used to report the wheels' volume control functions. The stylus report
- * (ID 16) has the same problems as the Slim Tablet 5.8 inch report has.
- *
- * The rest of the reports are unused, at least in the default configuration.
- * The purpose of the features is unknown.

- * Original Media Tablet 14.1 inch report descriptor.
- *
- * There are at least two versions of this model in the wild. They are
- * represented by Genius G-Pen M712 (older version) and Genius G-Pen M712X
- * (newer version). The hardware difference between these versions is the same
- * as between older and newer versions of Media Tablet 10.6 inch. The report
- * descriptors are identical for both versions.
- *
- * The function, behavior and report descriptor of this tablet is similar to
- * that of Media Tablet 10.6 inch. However, there is one more field (with
- * Consumer AC Pan usage) in the mouse description. Then the tablet X and Y
- * logical extents both get scaled to 0..16383 range (a hardware limit?),
- * which kind of defeats the advertised 4000 LPI resolution, considering the
- * physical extents of 12x7.25 inches. Plus, reports 5, 10 and 255 are used
- * sometimes (while moving the pen) with unknown purpose. Also, the key codes
- * generated for zoom in/out are different.

- * In Linux, we implement the KVP functionality in two components:
- * 1) The kernel component which is packaged as part of the hv_utils driver
- * is responsible for communicating with the host and responsible for
- * implementing the host/guest protocol. 2) A user level daemon that is
- * responsible for data gathering.
- *
- * Host/Guest Protocol: The host iterates over an index and expects the guest
- * to assign a key name to the index and also return the value corresponding to
- * the key. The host will have atmost one KVP transaction outstanding at any
- * given point in time. The host side iteration stops when the guest returns
- * an error. Microsoft has specified the following mapping of key names to
- * host specified index:
- *
- *	Index		Key Name
- *	0		FullyQualifiedDomainName
- *	1		IntegrationServicesVersion
- *	2		NetworkAddressIPv4
- *	3		NetworkAddressIPv6
- *	4		OSBuildNumber
- *	5		OSName
- *	6		OSMajorVersion
- *	7		OSMinorVersion
- *	8		OSVersion
- *	9		ProcessorArchitecture
- *
- * The Windows host expects the Key Name and Key Value to be encoded in utf16.
- *
- * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
- * data gathering functionality in a user mode daemon. The user level daemon
- * is also responsible for binding the key name to the index as well. The
- * kernel and user-level daemon communicate using a connector channel.
- *
- * The user mode component first registers with the
- * the kernel component. Subsequently, the kernel component requests, data
- * for the specified keys. In response to this message the user mode component
- * fills in the value corresponding to the specified key. We overload the
- * sequence field in the cn_msg header to define our KVP message types.
- *
- *
- * The kernel component simply acts as a conduit for communication between the
- * Windows host and the user-level daemon. The kernel component passes up the
- * index received from the Host to the user-level daemon. If the index is
- * valid (supported), the corresponding key as well as its
- * value (both are strings) is returned. If the index is invalid
- * (not supported), a NULL key string is returned.

- * Access to IDE device is possible through EBI Static Memory Controller
- * with Compact Flash logic. For details see EBI and SMC datasheet sections
- * of any microcontroller from AT91SAM9 family.
- *
- * Within SMC chip select address space, lines A[23:21] distinguish Compact
- * Flash modes (I/O, common memory, attribute memory, True IDE). IDE modes are:
- *   0x00c0000 - True IDE
- *   0x00e0000 - Alternate True IDE (Alt Status Register)
- *
- * On True IDE mode Task File and Data Register are mapped at the same address.
- * To distinguish access between these two different bus data width is used:
- * 8Bit for Task File, 16Bit for Data I/O.
- *
- * After initialization we do 8/16 bit flipping (changes in SMC MODE register)
- * only inside IDE callback routines which are serialized by IDE layer,
- * so no additional locking needed.

+   *NOTE 1 (debug interface):
    The IDI adapter of type 'IDI_DIMAINT' does register as 'request'
    famous 'dprintf' function (of type DI_PRINTF, please look
    include/debuglib.c and include/debuglib.h) for details.
    So dprintf is not exported from module debug module directly,
    instead of this IDI_DIMAINT is registered.
    Module load order will receive in this case:
-    1. DIDD (this file)
-    2. DIMAINT does load and register 'IDI_DIMAINT', at this step
-      DIDD should be able to get 'dprintf', save it, and
-      register with DIDD by means of 'dprintf' function.

- * Notable changes from the original source:
- * - includes stripped down to the essentials
- * - for loops used as delays replaced with udelay()
- * - #defines removed, changed to static values
- * - tuning structure changed - no more character arrays, other changes
+ * Fully tested with the Keene USB FM Transmitter and the v4l2-compliance tool.

+	 * 4. the internal clock frequency, given by ext_clock / n, is in the

+	 *    [out_clock_min, out_clock_max] range given by the limits
+	 *
+	 * The first naive approach is to iterate over all p1 values acceptable
+	 * according to (1) and all mf values acceptable according to (2), and
+	 * stop at the first combination that fulfills (3), (4) and (5). This
+	 * has a O(n^2) complexity.
+	 *
+	 * Instead of iterating over all mf values in the [mf_min, mf_max] range

+	 * according to (3) with
+	 *
+	 *	mf_inc = p1 / gcd(div, p1)			(6)
+	 *
+	 * and round the minimum up to the nearest multiple of mf_inc. This will
+	 * restrict the number of mf values to be checked.
+	 *
+	 * Furthermore, conditions (4) and (5) only restrict the range of
+	 * acceptable p1 and mf values by modifying the minimum and maximum
+	 * limits. (5) can be expressed as
+	 *
+	 *	ext_clock / (div * mf / p1) * m * mf >= out_clock_min
+	 *	ext_clock / (div * mf / p1) * m * mf <= out_clock_max

+	 * or

+	 *	p1 >= out_clock_min * div / (ext_clock * m)	(7)
+	 *	p1 <= out_clock_max * div / (ext_clock * m)
+	 *
+	 * Similarly, (4) can be expressed as
+	 *
+	 *	mf >= ext_clock * p1 / (int_clock_max * div)	(8)
+	 *	mf <= ext_clock * p1 / (int_clock_min * div)
+	 *
+	 * We can thus iterate over the restricted p1 range defined by the
+	 * combination of (1) and (7), and then compute the restricted mf range
+	 * defined by the combination of (2), (6) and (8). If the resulting mf
+	 * range is not empty, any value in the mf range is acceptable. We thus

- *
- * This module implements the virtual ethernet device for iSeries LPAR
- * Linux.  It uses hypervisor message passing to implement an
- * ethernet-like network device communicating between partitions on
- * the iSeries.
- *
- * The iSeries LPAR hypervisor currently allows for up to 16 different
- * virtual ethernets.  These are all dynamically configurable on
- * OS/400 partitions, but dynamic configuration is not supported under
- * Linux yet.  An ethXX network device will be created for each
- * virtual ethernet this partition is connected to.
- *
- * - This driver is responsible for routing packets to and from other
- *   partitions.  The MAC addresses used by the virtual ethernets
- *   contains meaning and must not be modified.
- *
- * - Having 2 virtual ethernets to the same remote partition DOES NOT
- *   double the available bandwidth.  The 2 devices will share the
- *   available hypervisor bandwidth.
- *
- * - If you send a packet to your own mac address, it will just be
- *   dropped, you won't get it on the receive side.
- *
- * - Multicast is implemented by sending the frame frame to every
- *   other partition.  It is the responsibility of the receiving
- *   partition to filter the addresses desired.
- *
- * Tunable parameters:
- *
- * VETH_NUMBUFFERS: This compile time option defaults to 120.  It
- * controls how much memory Linux will allocate per remote partition
- * it is communicating with.  It can be thought of as the maximum
- * number of packets outstanding to a remote partition at a time.

- * This call returns the statistics for a generic PHY in a sparse
- * array (indexed by the enumerate). Each value is represented by
- * a 32bit number.
- *
- * If the DMA_ADDR is 0, then no DMA is performed, and the statistics
- * may be read directly out of shared memory. If DMA_ADDR != 0, then
- * the statistics are dmad to that (page-aligned location)
- *
- * Locks required: None
- * Returns: 0, ETIME
- * Response methods: shared memory, event

+/**
+ * DOC: Virtual Function Driver Interface
+ *
+ * This file contains software structures used to form a two way
+ * communication channel between the VF driver and the PF driver,
+ * named Virtual Function Driver Interface (VFDI).
+ *
+ * For the purposes of VFDI, a page is a memory region with size and
+ * alignment of 4K.  All addresses are DMA addresses to be used within
+ * the domain of the relevant VF.
+ *
+ * The only hardware-defined channels for a VF driver to communicate
+ * with the PF driver are the event mailboxes (%FR_CZ_USR_EV
+ * registers).  Writing to these registers generates an event with
+ * EV_CODE = EV_CODE_USR_EV, USER_QID set to the index of the mailbox
+ * and USER_EV_REG_VALUE set to the value written.  The PF driver may
+ * direct or disable delivery of these events by setting
+ * %FR_CZ_USR_EV_CFG.
+ *
+ * The PF driver can send arbitrary events to arbitrary event queues.
+ * However, for consistency, VFDI events from the PF are defined to
+ * follow the same form and be sent to the first event queue assigned
+ * to the VF while that queue is enabled by the VF driver.
+ *
+ * The general form of the variable bits of VFDI events is:
+ *
+ *       0             16                       24   31
+ *      | DATA        | TYPE                   | SEQ   |
+ *
+ * SEQ is a sequence number which should be incremented by 1 (modulo
+ * 256) for each event.  The sequence numbers used in each direction
+ * are independent.
+ *
+ * The VF submits requests of type &struct vfdi_req by sending the
+ * address of the request (ADDR) in a series of 4 events:
+ *
+ *       0             16                       24   31
+ *      | ADDR[0:15]  | VFDI_EV_TYPE_REQ_WORD0 | SEQ   |
+ *      | ADDR[16:31] | VFDI_EV_TYPE_REQ_WORD1 | SEQ+1 |
+ *      | ADDR[32:47] | VFDI_EV_TYPE_REQ_WORD2 | SEQ+2 |
+ *      | ADDR[48:63] | VFDI_EV_TYPE_REQ_WORD3 | SEQ+3 |
+ *
+ * The address must be page-aligned.  After receiving such a valid
+ * series of events, the PF driver will attempt to read the request
+ * and write a response to the same address.  In case of an invalid
+ * sequence of events or a DMA error, there will be no response.
+ *
+ * The VF driver may request that the PF driver writes status
+ * information into its domain asynchronously.  After writing the
+ * status, the PF driver will send an event of the form:
+ *
+ *       0             16                       24   31
+ *      | reserved    | VFDI_EV_TYPE_STATUS    | SEQ   |
+ *
+ * In case the VF must be reset for any reason, the PF driver will
+ * send an event of the form:
+ *
+ *       0             16                       24   31
+ *      | reserved    | VFDI_EV_TYPE_RESET     | SEQ   |
+ *
+ * It is then the responsibility of the VF driver to request
+ * reinitialisation of its queues.

-/**
- * DOC: Bus layer - role and goal
- *
- * iwl-bus.h defines the API to the bus layer of the iwlwifi driver.
- * The bus layer is responsible for doing very basic bus operations that are
- * listed in the iwl_bus_ops structure.
- * 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
- * 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.
- * This implementation is iwl-pci.c
- */
-
-/**
- * DOC: encapsulation and type safety
- *
- * 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.
- *
- * In order to achieve encapsulation, iwl_priv cannot be dereferenced from the
- * bus layer. Type safety is still kept since functions that gets iwl_priv gets
- * a typed pointer (as opposed to void *).

-
-/**
- * DOC: probe flow
- *
- * The module_init calls the bus specific registration function. The
- * registration to the bus layer will trigger an enumeration of the bus which
- * will call the bus specific probe function.
- * The first thing this function must do is to allocate the memory needed by
- * iwl_bus + the bus_specific data.
- * Once the bus specific probe function has configured the hardware, it
- * chooses the appropriate transport layer and calls iwl_probe that will run
- * the bus independent probe flow.
- *
- * Note: The bus specific code must set the following data in iwl_bus before it
- *       calls iwl_probe:

+ * DOC: Driver system flows - drv component
+ *
+ * This component implements the system flows such as bus enumeration, bus
+ * removal. Bus dependent parts of system flows (such as iwl_pci_probe) are in
+ * bus specific files (transport files). This is the code that is common among
+ * different buses.
+ *
+ * This component is also in charge of managing the several implementations of
+ * the wifi flows: it will allow to have several fw API implementation. These
+ * different implementations will differ in the way they implement mac80211's
+ * handlers too.
+
+ * The init flow wrt to the drv component looks like this:
+ * 1) The bus specific component is called from module_init
+ * 2) The bus specific component registers the bus driver
+ * 3) The bus driver calls the probe function
+ * 4) The bus specific component configures the bus
+ * 5) The bus specific component calls to the drv bus agnostic part
+ *    (iwl_drv_start)
+ * 6) iwl_drv_start fetches the fw ASYNC, iwl_ucode_callback
+ * 7) iwl_ucode_callback parses the fw file
+ * 8) iwl_ucode_callback starts the wifi implementation to matches the fw

+/**
+ * DOC: Operational mode - what is it ?
+ *
+ * The operational mode (a.k.a. op_mode) is the layer that implements
+ * mac80211's handlers. It knows two APIs: mac80211's and the fw's. It uses
+ * the transport API to access the HW. The op_mode doesn't need to know how the
+ * underlying HW works, since the transport layer takes care of that.
+ *
+ * There can be several op_mode: i.e. different fw APIs will require two
+ * different op_modes. This is why the op_mode is virtualized.
+ */
+
+/**
+ * DOC: Life cycle of the Operational mode
+ *
+ * The operational mode has a very simple life cycle.
+ *
+ *	1) The driver layer (iwl-drv.c) chooses the op_mode based on the
+ *	   capabilities advertized by the fw file (in TLV format).
+ *	2) The driver layer starts the op_mode (ops->start)
+ *	3) The op_mode registers registers mac80211
+ *	4) The op_mode is governed by mac80211
+ *	5) The driver layer stops the op_mode
+ */
+
+/**
+ * struct iwl_op_mode_ops - op_mode specific operations
+ *
+ * The op_mode exports its ops so that external components can start it and
+ * interact with it. The driver layer typically calls the start and stop
+ * handlers, the transport layer calls the others.
+ *
+ * All the handlers MUST be implemented
+ *
+ * @start: start the op_mode. The transport layer is already allocated.
+ *	May sleep
+ * @stop: stop the op_mode. Must free all the memory allocated.
+ *	May sleep
+ * @rx: Rx notification to the op_mode. rxb is the Rx buffer itself. Cmd is the
+ *	HCMD the this Rx responds to.
+ *	Must be atomic.
+ * @queue_full: notifies that a HW queue is full. Ac is the ac of the queue
+ *	Must be atomic
+ * @queue_not_full: notifies that a HW queue is not full any more.
+ *	Ac is the ac of the queue. Must be atomic
+ * @hw_rf_kill:notifies of a change in the HW rf kill switch. True means that
+ *	the radio is killed. Must be atomic.
+ * @free_skb: allows the transport layer to free skbs that haven't been
+ *	reclaimed by the op_mode. This can happen when the driver is freed and
+ *	there are Tx packets pending in the transport layer.
+ *	Must be atomic
+ * @nic_error: error notification. Must be atomic
+ * @cmd_queue_full: Called when the command queue gets full. Must be atomic.
+ * @nic_config: configure NIC, called before firmware is started.

+ *	2) Bus's probe calls to the transport layer's allocation functions.

- * @mux_requested: whether the pin is already requested by pinmux or not

-	 * ======== The Lincroft Message Bus Interface ========
-	 * Lincroft registers may be obtained via PCI from
-	 * the host bridge using the Lincroft Message Bus
-	 * Interface.  That message bus interface is generally
-	 * comprised of two registers: a control register (MCR, 0xDO)
-	 * and a data register (MDR, 0xD4).
-	 *
-	 * The MCR (message control register) format is the following:
-	 *   1.  [31:24]: Opcode
-	 *   2.  [23:16]: Port
-	 *   3.  [15:8]: Register Offset
-	 *   4.  [7:4]: Byte Enables (use 0xF to set all of these bits
-	 *              to 1)
-	 *   5.  [3:0]: reserved
-	 *
-	 *  Read (0xD0) and write (0xE0) opcodes are written to the
-	 *  control register when reading and writing to Lincroft
-	 *  registers, respectively.
-	 *
-	 *  We're interested in registers found in the Lincroft
-	 *  B-unit.  The B-unit port is 0x3.
-	 *
-	 *  The six B-unit RAR register offsets we use are listed
-	 *  earlier in this file.
-	 *
-	 *  Lastly writing to the MCR register requires the "Byte
-	 *  enables" bits to be set to 1.  This may be achieved by
-	 *  writing 0xF at bit 4.
-	 *
-	 * The MDR (message data register) format is the following:
-	 *   1. [31:0]: Read/Write Data
-	 *
-	 *  Data being read from this register is only available after
-	 *  writing the appropriate control message to the MCR
-	 *  register.
-	 *
-	 *  Data being written to this register must be written before
-	 *  writing the appropriate control message to the MCR
-	 *  register.

+Industrial I/O Subsystem in kernel consumers.
+
+The IIO subsystem can act as a layer under other elements of the kernel
+providing a means of obtaining ADC type readings or of driving DAC type
+signals.  The functionality supported will grow as use cases arise.
+
+Describing the channel mapping (iio/machine.h)
+
+Channel associations are described using:
+
+struct iio_map {
+	const char *adc_channel_label;
+	const char *consumer_dev_name;
+	const char *consumer_channel;
+};
+
+adc_channel_label identifies the channel on the IIO device by being
+matched against the datasheet_name field of the iio_chan_spec.
+
+consumer_dev_name allows identification of the consumer device.
+This are then used to find the channel mapping from the consumer device (see
+below).
+
+Finally consumer_channel is a string identifying the channel to the consumer.
+(Perhaps 'battery_voltage' or similar).
+
+An array of these structures is then passed to the IIO driver.
+
+Supporting in kernel interfaces in the driver (driver.h)
+
+The driver must provide datasheet_name values for its channels and
+must pass the iio_map structures and a pointer to its own iio_dev structure
+ on to the core via a call to iio_map_array_register.  On removal,
+iio_map_array_unregister reverses this process.
+
+The result of this is that the IIO core now has all the information needed
+to associate a given channel with the consumer requesting it.
+
+Acting as an IIO consumer (consumer.h)
+
+The consumer first has to obtain an iio_channel structure from the core
+by calling iio_channel_get().  The correct channel is identified by:
+
+* matching dev or dev_name against consumer_dev and consumer_dev_name
+* matching consumer_channel against consumer_channel in the map
+
+There are then a number of functions that can be used to get information
+about this channel such as it's current reading.
+
+e.g.
+iio_st_read_channel_raw() - get a reading
+iio_st_read_channel_type() - get the type of channel
+
+There is also provision for retrieving all of the channels associated
+with a given consumer.  This is useful for generic drivers such as
+iio_hwmon where the number and naming of channels is not known by the
+consumer driver.  To do this, use iio_st_channel_get_all.

+	PCM mode bits.
+
+	There are several features of the Line6 USB driver which require PCM
+	data to be exchanged with the device:
+	*) PCM playback and capture via ALSA
+	*) software monitoring (for devices without hardware monitoring)
+	*) optional impulse response measurement
+	However, from the device's point of view, there is just a single
+	capture and playback stream, which must be shared between these
+	subsystems. It is therefore necessary to maintain the state of the
+	subsystems with respect to PCM usage. We define several constants of
+	the form LINE6_BIT_PCM_<subsystem>_<direction>_<resource> with the
+	following meanings:
+	*) <subsystem> is one of
+	-) ALSA: PCM playback and capture via ALSA
+	-) MONITOR: software monitoring
+	-) IMPULSE: optional impulse response measurement
+	*) <direction> is one of
+	-) PLAYBACK: audio output (from host to device)
+	-) CAPTURE: audio input (from device to host)
+	*) <resource> is one of
+	-) BUFFER: buffer required by PCM data stream
+	-) STREAM: actual PCM data stream
+
+	The subsystems call line6_pcm_acquire() to acquire the (shared)
+	resources needed for a particular operation (e.g., allocate the buffer
+	for ALSA playback or start the capture stream for software monitoring).
+	When a resource is no longer needed, it is released by calling
+	line6_pcm_release(). Buffer allocation and stream startup are handled
+	separately to allow the ALSA kernel driver to perform them at
+	appropriate places (since the callback which starts a PCM stream is not
+	allowed to sleep).

+OZWPAN USB Host Controller Driver
+---------------------------------
+This driver is a USB HCD driver that does not have an associated a physical
+device but instead uses Wi-Fi to communicate with the wireless peripheral.
+The USB requests are converted into a layer 2 network protocol and transmitted
+on the network using an ethertype (0x892e) regestered to Ozmo Device Inc.
+This driver is compatible with existing wireless devices that use Ozmo Devices
+technology.
+
+To operate the driver must be bound to a suitable network interface. This can
+be done when the module is loaded (specifying the name of the network interface
+as a paramter - e.g. 'insmod ozwpan g_net_dev=go0') or can be bound after
+loading using an ioctl call. See the ozappif.h file and the ioctls
+OZ_IOCTL_ADD_BINDING and OZ_IOCTL_REMOVE_BINDING.
+
+The devices connect to the host use Wi-Fi Direct so a network card that supports
+Wi-Fi direct is required. A recent version (0.8.x or later) version of the
+wpa_supplicant can be used to setup the network interface to create a persistent
+autonomous group (for older pre-WFD peripherals) or put in a listen state to
+allow group negotiation to occur for more recent devices that support WFD.
+
+The protocol used over the network does not directly mimic the USB bus
+transactions as this would be rather busy and inefficient. Instead the chapter 9
+requests are converted into a request/response pair of messages. (See
+ozprotocol.h for data structures used in the protocol).

+ * This file provides the implementation of a USB host controller device that
+ * does not have any associated hardware. Instead the virtual device is
+ * connected to the WiFi network and emulates the operation of a USB hcd by
+ * receiving and sending network frames.
+ * Note:
+ * We take great pains to reduce the amount of code where interrupts need to be
+ * disabled and in this respect we are different from standard HCD's. In
+ * particular we don't want in_irq() code bleeding over to the protocol side of
+ * the driver.
+ * The troublesome functions are the urb enqueue and dequeue functions both of
+ * which can be called in_irq(). So for these functions we put the urbs into a
+ * queue and request a tasklet to process them. This means that a spinlock with
+ * interrupts disabled must be held for insertion and removal but most code is
+ * is in tasklet or soft irq context. The lock that protects this list is called
+ * the tasklet lock and serves the purpose of the 'HCD lock' which must be held
+ * when calling the following functions.
+ *   usb_hcd_link_urb_to_ep()

+For this staging driver, RAMster duplicates code from drivers/staging/zcache
+then incorporates changes to the local copy of the code.  For V5, it also
+directly incorporates the soon-to-be-removed drivers/staging/zram/xvmalloc.[ch]
+as all testing has been done with xvmalloc rather than the new zsmalloc.
+Before RAMster can be promoted from staging, the zcache and RAMster drivers
+should be either merged or reorganized to separate out common code.
+
+Until V4, RAMster duplicated code from fs/ocfs2/cluster, but this made
+RAMster incompatible with ocfs2 running in the same kernel and included
+lots of code that could be removed.  As of V5, the ocfs2 code has been
+mined and made RAMster-specific, made to communicate with a userland
+ramster-tools package rather than ocfs2-tools, and can co-exist with ocfs2
+both in the same kernel and in userland on the same machine.

+ * For now this is a trivial wrapper around printk() that gives the critical
+ * ability to enable sets of debugging output at run-time.  In the future this
+ * will almost certainly be redirected to relayfs so that it can pay a
+ * substantially lower heisenberg tax.
+ *
+ * Callers associate the message with a bitmask and a global bitmask is
+ * maintained with help from /proc.  If any of the bits match the message is
+ * output.
+ *
+ * We must have efficient bit tests on i386 and it seems gcc still emits crazy
+ * code for the 64bit compare.  It emits very good code for the dual unsigned
+ * long tests, though, completely avoiding tests that can never pass if the
+ * caller gives a constant bitmask that fills one of the longs with all 0s.  So
+ * the desire is to have almost all of the calls decided on by comparing just
+ * one of the longs.  This leads to having infrequently given bits that are
+ * frequently matched in the high bits.
+ *
+ * _ERROR and _NOTICE are used for messages that always go to the console and
+ * have appropriate KERN_ prefixes.  We wrap these in our function instead of
+ * just calling printk() so that this can eventually make its way through
+ * relayfs along with the debugging messages.  Everything else gets KERN_DEBUG.
+ * The inline tests and macro dance give GCC the opportunity to quite cleverly
+ * only emit the appropriage printk() when the caller passes in a constant
+ * mask, as is almost always the case.
+ *
+ * All this bitmask nonsense is managed from the files under
+ * /sys/fs/r2cb/logmask/.  Reading the files gives a straightforward
+ * indication of which bits are allowed (allow) or denied (off/deny).
+ *	ENTRY deny
+ *	EXIT deny
+ *	TCP off
+ *	MSG off
+ *	SOCKET off
+ *	ERROR allow
+ *	NOTICE allow
+ *
+ * Writing changes the state of a given bit and requires a strictly formatted
+ * single write() call:
+ *
+ *	write(fd, "allow", 5);
+ *
+ * Echoing allow/deny/off string into the logmask files can flip the bits
+ * on or off as expected; here is the bash script for example:
+ *
+ * log_mask="/sys/fs/r2cb/log_mask"
+ * for node in ENTRY EXIT TCP MSG SOCKET ERROR NOTICE; do
+ *	echo allow >"$log_mask"/"$node"
+ * done
+ *
+ * The debugfs.ramster tool can also flip the bits with the -l option:

+ * ----
+ *
+ * Callers for this were originally written against a very simple synchronus
+ * API.  This implementation reflects those simple callers.  Some day I'm sure
+ * we'll need to move to a more robust posting/callback mechanism.
+ *
+ * Transmit calls pass in kernel virtual addresses and block copying this into
+ * the socket's tx buffers via a usual blocking sendmsg.  They'll block waiting
+ * for a failed socket to timeout.  TX callers can also pass in a poniter to an
+ * 'int' which gets filled with an errno off the wire in response to the
+ * message they send.
+ *
+ * Handlers for unsolicited messages are registered.  Each socket has a page
+ * that incoming data is copied into.  First the header, then the data.
+ * Handlers are called from only one thread with a reference to this per-socket
+ * page.  This page is destroyed after the handler call, so it can't be
+ * referenced beyond the call.  Handlers may block but are discouraged from
+ * doing so.
+ *
+ * Any framing errors (bad magic, large payload lengths) close a connection.
+ *
+ * Our sock_container holds the state we associate with a socket.  It's current
+ * framing state is held there as well as the refcounting we do around when it
+ * is safe to tear down the socket.  The socket is only finally torn down from
+ * the container when the container loses all of its references -- so as long
+ * as you hold a ref on the container you can trust that the socket is valid
+ * for use with kernel socket APIs.
+ *
+ * Connections are initiated between a pair of nodes when the node with the
+ * higher node number gets a heartbeat callback which indicates that the lower
+ * numbered node has started heartbeating.  The lower numbered node is passive
+ * and only accepts the connection if the higher numbered node is heartbeating.

+ *
+ * The primary purpose of Transcedent Memory ("tmem") is to map object-oriented
+ * "handles" (triples containing a pool id, and object id, and an index), to
+ * pages in a page-accessible memory (PAM).  Tmem references the PAM pages via
+ * an abstract "pampd" (PAM page-descriptor), which can be operated on by a
+ * set of functions (pamops).  Each pampd contains some representation of
+ * PAGE_SIZE bytes worth of data. Tmem must support potentially millions of
+ * pages and must be able to insert, find, and delete these pages at a
+ * potential frequency of thousands per second concurrently across many CPUs,
+ * (and, if used with KVM, across many vcpus across many guests).
+ * Tmem is tracked with a hierarchy of data structures, organized by
+ * the elements in a handle-tuple: pool_id, object_id, and page index.
+ * One or more "clients" (e.g. guests) each provide one or more tmem_pools.
+ * Each pool, contains a hash table of rb_trees of tmem_objs.  Each
+ * tmem_obj contains a radix-tree-like tree of pointers, with intermediate
+ * nodes called tmem_objnodes.  Each leaf pointer in this tree points to
+ * a pampd, which is accessible only through a small set of callbacks
+ * registered by the PAM implementation (see tmem_register_pamops). Tmem
+ * does all memory allocation via a set of callbacks registered by the tmem
+ * host implementation (e.g. see tmem_register_hostops).

+ * Zcache provides an in-kernel "host implementation" for transcendent memory
+ * and, thus indirectly, for cleancache and frontswap.  Zcache includes two
+ * page-accessible memory [1] interfaces, both utilizing lzo1x compression:
+ * 1) "compression buddies" ("zbud") is used for ephemeral pages
+ * 2) xvmalloc is used for persistent pages.
+ * Xvmalloc (based on the TLSF allocator) has very low fragmentation
+ * so maximizes space efficiency, while zbud allows pairs (and potentially,
+ * in the future, more than a pair of) compressed pages to be closely linked
+ * so that reclaiming can be done via the kernel's physical-page-oriented
+ * "shrinker" interface.
+ *
+ * [1] For a definition of page-accessible memory (aka PAM), see:
+ *   http://marc.info/?l=linux-mm&m=127811271605009
+ *  RAMSTER TODO:
+ *   - handle remotifying of buddied pages (see zbud_remotify_zbpg)
+ *   - kernel boot params: nocleancache/nofrontswap don't always work?!?

+	  zsmalloc is a slab-based memory allocator designed to store
+	  compressed RAM pages.  zsmalloc uses virtual memory mapping
+	  in order to reduce fragmentation.  However, this results in a
+	  non-standard allocator interface where a handle, not a pointer, is
+	  returned by an alloc().  This handle must be mapped in order to
+	  access the allocated space.

+	  This selects whether you want to include the driver for the standard
+	  serial ports.  The standard answer is Y.  People who might say N
+	  here are those that are setting up dedicated Ethernet WWW/FTP
+	  servers, or users that have one of the various bus mice instead of a
+	  serial mouse and don't intend to use their machine's standard serial
+	  port for anything.  (Note that the Cyclades and Stallion multi
+	  serial port drivers do not need this driver built in for them to
+	  work.)
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called 8250.
+	  [WARNING: Do not compile this driver as a module if you are using
+	  non-standard serial ports, since the configuration information will
+	  be lost when the driver is unloaded.  This limitation may be lifted
+	  in the future.]
+
+	  BTW1: If you have a mouseman serial mouse which is not recognized by
+	  the X window system, try running gpm first.
+
+	  BTW2: If you intend to use a software modem (also called Winmodem)
+	  under Linux, forget it.  These modems are crippled and require
+	  proprietary drivers which are only available under Windows.
+
+	  Most people will say Y or M here, so that they can use serial mice,
+	  modems and similar devices connecting to the standard serial ports.

+	select SERIAL_CORE_CONSOLE
+	---help---
+	  If you say Y here, it will be possible to use a serial port as the
+	  system console (the system console is the device which receives all
+	  kernel messages and warnings and which allows logins in single user
+	  mode). This could be useful if some terminal or printer is connected
+	  to that serial port.
+
+	  Even if you say Y here, the currently visible virtual console
+	  (/dev/tty0) will still be used as the system console by default, but
+	  you can alter that using a kernel command line option such as
+	  "console=ttyS1". (Try "man bootparam" or see the documentation of
+	  your boot loader (grub or lilo or loadlin) about how to pass options
+	  to the kernel at boot time.)
+
+	  If you don't have a VGA card installed and you say Y here, the
+	  kernel will automatically use the first serial line, /dev/ttyS0, as
+	  system console.
+
+	  You can set that using a kernel command line option such as
+	  "console=uart8250,io,0x3f8,9600n8"
+	  "console=uart8250,mmio,0xff5e0000,115200n8".
+	  and it will switch to normal serial console when the corresponding
+	  port is ready.
+	  "earlycon=uart8250,io,0x3f8,9600n8"
+	  "earlycon=uart8250,mmio,0xff5e0000,115200n8".
+	  it will not only setup early console.

-	select SERIAL_CORE
-	---help---
-	  This selects whether you want to include the driver for the standard
-	  serial ports.  The standard answer is Y.  People who might say N
-	  here are those that are setting up dedicated Ethernet WWW/FTP
-	  servers, or users that have one of the various bus mice instead of a
-	  serial mouse and don't intend to use their machine's standard serial
-	  port for anything.  (Note that the Cyclades and Stallion multi
-	  serial port drivers do not need this driver built in for them to
-	  work.)
-
-	  To compile this driver as a module, choose M here: the
-	  module will be called 8250.
-	  [WARNING: Do not compile this driver as a module if you are using
-	  non-standard serial ports, since the configuration information will
-	  be lost when the driver is unloaded.  This limitation may be lifted
-	  in the future.]
-
-	  BTW1: If you have a mouseman serial mouse which is not recognized by
-	  the X window system, try running gpm first.
-
-	  BTW2: If you intend to use a software modem (also called Winmodem)
-	  under Linux, forget it.  These modems are crippled and require
-	  proprietary drivers which are only available under Windows.
-
-	  Most people will say Y or M here, so that they can use serial mice,
-	  modems and similar devices connecting to the standard serial ports.

-	  If you say Y here, it will be possible to use a serial port as the
-	  system console (the system console is the device which receives all
-	  kernel messages and warnings and which allows logins in single user
-	  mode). This could be useful if some terminal or printer is connected
-	  to that serial port.
-
-	  Even if you say Y here, the currently visible virtual console
-	  (/dev/tty0) will still be used as the system console by default, but
-	  you can alter that using a kernel command line option such as
-	  "console=ttyS1". (Try "man bootparam" or see the documentation of
-	  your boot loader (grub or lilo or loadlin) about how to pass options
-	  to the kernel at boot time.)
-
-	  If you don't have a VGA card installed and you say Y here, the
-	  kernel will automatically use the first serial line, /dev/ttyS0, as
-	  system console.
-
-	  You can set that using a kernel command line option such as
-	  "console=uart8250,io,0x3f8,9600n8"
-	  "console=uart8250,mmio,0xff5e0000,115200n8".
-	  and it will switch to normal serial console when the corresponding 
-	  port is ready.

-	  "earlycon=uart8250,mmio,0xff5e0000,115200n8".
