+What:		/dev/fw[0-9]+
+Date:		May 2007
+KernelVersion:	2.6.22
+Contact:	linux1394-devel@lists.sourceforge.net
+Description:
+		The character device files /dev/fw* are the interface between
+		firewire-core and IEEE 1394 device drivers implemented in
+		userspace.  The ioctl(2)- and read(2)-based ABI is defined and
+		documented in <linux/firewire-cdev.h>.
+
+		This ABI offers most of the features which firewire-core also
+		exposes to kernelspace IEEE 1394 drivers.
+
+		Each /dev/fw* is associated with one IEEE 1394 node, which can
+		be remote or local nodes.  Operations on a /dev/fw* file have
+		different scope:
+		  - The 1394 node which is associated with the file:
+			  - Asynchronous request transmission
+			  - Get the Configuration ROM
+			  - Query node ID
+			  - Query maximum speed of the path between this node
+			    and local node
+		  - The 1394 bus (i.e. "card") to which the node is attached to:
+			  - Isochronous stream transmission and reception
+			  - Asynchronous stream transmission and reception
+			  - Asynchronous broadcast request transmission
+			  - PHY packet transmission and reception
+			  - Allocate, reallocate, deallocate isochronous
+			    resources (channels, bandwidth) at the bus's IRM
+			  - Query node IDs of local node, root node, IRM, bus
+			    manager
+			  - Query cycle time
+			  - Bus reset initiation, bus reset event reception
+		  - All 1394 buses:
+			  - Allocation of IEEE 1212 address ranges on the local
+			    link layers, reception of inbound requests to such
+			    an address range, asynchronous response transmission
+			    to inbound requests
+			  - Addition of descriptors or directories to the local
+			    nodes' Configuration ROM
+
+		Due to the different scope of operations and in order to let
+		userland implement different access permission models, some
+		operations are restricted to /dev/fw* files that are associated
+		with a local node:
+			  - Addition of descriptors or directories to the local
+			    nodes' Configuration ROM
+			  - PHY packet transmission and reception
+
+		A /dev/fw* file remains associated with one particular node
+		during its entire life time.  Bus topology changes, and hence
+		node ID changes, are tracked by firewire-core.  ABI users do not
+		need to be aware of topology.
+
+		The following file operations are supported:
+
+		open(2)
+		Currently the only useful flags are O_RDWR.
+
+		ioctl(2)
+		Initiate various actions.  Some take immediate effect, others
+		are performed asynchronously while or after the ioctl returns.
+		See the inline documentation in <linux/firewire-cdev.h> for
+		descriptions of all ioctls.
+
+		poll(2), select(2), epoll_wait(2) etc.
+		Watch for events to become available to be read.
+
+		read(2)
+		Receive various events.  There are solicited events like
+		outbound asynchronous transaction completion or isochronous
+		buffer completion, and unsolicited events such as bus resets,
+		request reception, or PHY packet reception.  Always use a read
+		buffer which is large enough to receive the largest event that
+		could ever arrive.  See <linux/firewire-cdev.h> for descriptions
+		of all event types and for which ioctls affect reception of
+		events.
+
+		mmap(2)
+		Allocate a DMA buffer for isochronous reception or transmission
+		and map it into the process address space.  The arguments should
+		be used as follows:  addr = NULL, length = the desired buffer
+		size, i.e. number of packets times size of largest packet,
+		prot = at least PROT_READ for reception and at least PROT_WRITE
+		for transmission, flags = MAP_SHARED, fd = the handle to the
+		/dev/fw*, offset = 0.
+
+		Isochronous reception works in packet-per-buffer fashion except
+		for multichannel reception which works in buffer-fill mode.
+
+		munmap(2)
+		Unmap the isochronous I/O buffer from the process address space.
+
+		close(2)
+		Besides stopping and freeing I/O contexts that were associated
+		with the file descriptor, back out any changes to the local
+		nodes' Configuration ROM.  Deallocate isochronous channels and
+		bandwidth at the IRM that were marked for kernel-assisted
+		re- and deallocation.

+On some architectures, when the kernel loads any userspace program it
+maps an ELF DSO into that program's address space.  This DSO is called
+the vDSO and it often contains useful and highly-optimized alternatives
+to real syscalls.
+
+These functions are called just like ordinary C function according to
+your platform's ABI.  Call them from a sensible context.  (For example,
+if you set CS on x86 to something strange, the vDSO functions are
+within their rights to crash.)  In addition, if you pass a bad
+pointer to a vDSO function, you might get SIGSEGV instead of -EFAULT.
+
+To find the DSO, parse the auxiliary vector passed to the program's
+entry point.  The AT_SYSINFO_EHDR entry will point to the vDSO.
+
+The vDSO uses symbol versioning; whenever you request a symbol from the
+vDSO, specify the version you are expecting.
+
+Programs that dynamically link to glibc will use the vDSO automatically.
+Otherwise, you can use the reference parser in Documentation/vDSO/parse_vdso.c.
+
+Unless otherwise noted, the set of symbols with any given version and the
+ABI of those symbols is considered stable.  It may vary across architectures,
+though.

-		demodulator:</para>
-
-	<para>This ISDB-T/ISDB-Tsb API extension should reflect all information
-		needed to tune any ISDB-T/ISDB-Tsb hardware. Of course it is possible
-		that some very sophisticated devices won't need certain parameters to
-		tune.</para>
-
-	<para>The information given here should help application writers to know how
-		to handle ISDB-T and ISDB-Tsb hardware using the Linux DVB-API.</para>
-
-	<para>The details given here about ISDB-T and ISDB-Tsb are just enough to
-		basically show the dependencies between the needed parameter values,
-		but surely some information is left out. For more detailed information

-
-	<para>In order to read this document one has to have some knowledge the
-		channel structure in ISDB-T and ISDB-Tsb. I.e. it has to be known to
-		the reader that an ISDB-T channel consists of 13 segments, that it can
-		have up to 3 layer sharing those segments, and things like that.</para>

-
-			<para>An ISDB-Tsb channel (1 or 3 segments) can be broadcasted alone or in a
-				set of connected ISDB-Tsb channels. In this set of channels every
-				channel can be received independently. The number of connected
-				ISDB-Tsb segment can vary, e.g. depending on the frequency spectrum
-				bandwidth available.</para>
-
-			<para>Example: Assume 8 ISDB-Tsb connected segments are broadcasted. The
-				broadcaster has several possibilities to put those channels in the
-				air: Assuming a normal 13-segment ISDB-T spectrum he can align the 8
-				segments from position 1-8 to 5-13 or anything in between.</para>
-
-			<para>The underlying layer of segments are subchannels: each segment is
-				consisting of several subchannels with a predefined IDs. A sub-channel
-				is used to help the demodulator to synchronize on the channel.</para>
-
-			<para>An ISDB-T channel is always centered over all sub-channels. As for
-				the example above, in ISDB-Tsb it is no longer as simple as that.</para>

-				ISDB-T hierarchical layers can be decoded simultaneously. For that
-				reason a ISDB-T demodulator has 3 viterbi and 3 reed-solomon-decoders.</para>

-				<title><constant>DTV_ISDBT_LAYER_ENABLED</constant></title>
-
-				<para>Hierarchical reception in ISDB-T is achieved by enabling or disabling
-					layers in the decoding process. Setting all bits of

-
-				<para>If the channel is in the partial reception mode
-					(<constant>DTV_ISDBT_PARTIAL_RECEPTION</constant> = 1) the central segment can be decoded

+		<para>This ISDB-T/ISDB-Tsb API extension should reflect all information
+			needed to tune any ISDB-T/ISDB-Tsb hardware. Of course it is possible
+			that some very sophisticated devices won't need certain parameters to
+			tune.</para>
+		<para>The information given here should help application writers to know how
+			to handle ISDB-T and ISDB-Tsb hardware using the Linux DVB-API.</para>
+		<para>The details given here about ISDB-T and ISDB-Tsb are just enough to
+			basically show the dependencies between the needed parameter values,
+			but surely some information is left out. For more detailed information
+			see the following documents:</para>

+			Television Broadcasting" and</para>
+		<para>ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial
+			Television Broadcasting".</para>
+		<para>In order to understand the ISDB specific parameters,
+			one has to have some knowledge the channel structure in
+			ISDB-T and ISDB-Tsb. I.e. it has to be known to
+			the reader that an ISDB-T channel consists of 13 segments,
+			that it can have up to 3 layer sharing those segments,
+			and things like that.</para>

+		value.</para>

-  <para>The V4L2 event interface provides means for user to get
-  immediately notified on certain conditions taking place on a device.
-  This might include start of frame or loss of signal events, for
-  example.
-  </para>
-
-  <para>To receive events, the events the user is interested in first must
-  be subscribed using the &VIDIOC-SUBSCRIBE-EVENT; ioctl. Once an event is
-  subscribed, the events of subscribed types are dequeueable using the
-  &VIDIOC-DQEVENT; ioctl. Events may be unsubscribed using
-  VIDIOC_UNSUBSCRIBE_EVENT ioctl. The special event type V4L2_EVENT_ALL may
-  be used to unsubscribe all the events the driver supports.</para>
-
-  <para>The event subscriptions and event queues are specific to file
-  handles. Subscribing an event on one file handle does not affect
-  other file handles.
-  </para>
-
-  <para>The information on dequeueable events is obtained by using select or
-  poll system calls on video devices. The V4L2 events use POLLPRI events on
-  poll system call and exceptions on select system call.  </para>

-    <title>Description</title>
-
-    <para>The <function>ioctl()</function> function is used to program
-V4L2 devices. The argument <parameter>fd</parameter> must be an open
-file descriptor. An ioctl <parameter>request</parameter> has encoded
-in it whether the argument is an input, output or read/write
-parameter, and the size of the argument <parameter>argp</parameter> in
-bytes. Macros and defines specifying V4L2 ioctl requests are located
-in the <filename>videodev2.h</filename> header file.
-Applications should use their own copy, not include the version in the
-kernel sources on the system they compile on. All V4L2 ioctl requests,
-their respective function and parameters are specified in <xref
-	linkend="user-func" />.</para>
-  </refsect1>
-
-  <refsect1>
-    <title>Return Value</title>
-
-    <para>On success the <function>ioctl()</function> function returns
-<returnvalue>0</returnvalue> and does not reset the
-<varname>errno</varname> variable. On failure
-<returnvalue>-1</returnvalue> is returned, when the ioctl takes an
-output or read/write parameter it remains unmodified, and the
-<varname>errno</varname> variable is set appropriately. See below for
-possible error codes. Generic errors like <errorcode>EBADF</errorcode>
-or <errorcode>EFAULT</errorcode> are not listed in the sections
-discussing individual ioctl requests.</para>
-    <para>Note ioctls may return undefined error codes. Since errors
-may have side effects such as a driver reset applications should
-abort on unexpected errors.</para>

+Kernel-provided User Helpers
+============================
+
+These are segment of kernel provided user code reachable from user space
+at a fixed address in kernel memory.  This is used to provide user space
+with some operations which require kernel help because of unimplemented
+native feature and/or instructions in many ARM CPUs. The idea is for this
+code to be executed directly in user mode for best efficiency but which is
+too intimate with the kernel counter part to be left to user libraries.
+In fact this code might even differ from one CPU to another depending on
+the available instruction set, or whether it is a SMP systems. In other
+words, the kernel reserves the right to change this code as needed without
+warning. Only the entry points and their results as documented here are
+guaranteed to be stable.
+
+This is different from (but doesn't preclude) a full blown VDSO
+implementation, however a VDSO would prevent some assembly tricks with
+constants that allows for efficient branching to those code segments. And
+since those code segments only use a few cycles before returning to user
+code, the overhead of a VDSO indirect far call would add a measurable
+overhead to such minimalistic operations.
+
+User space is expected to bypass those helpers and implement those things
+inline (either in the code emitted directly by the compiler, or part of
+the implementation of a library call) when optimizing for a recent enough
+processor that has the necessary native support, but only if resulting
+binaries are already to be incompatible with earlier ARM processors due to
+useage of similar native instructions for other things.  In other words
+don't make binaries unable to run on earlier processors just for the sake
+of not using these kernel helpers if your compiled code is not going to
+use new instructions for other purpose.
+
+New helpers may be added over time, so an older kernel may be missing some
+helpers present in a newer kernel.  For this reason, programs must check
+the value of __kuser_helper_version (see below) before assuming that it is
+safe to call any particular helper.  This check should ideally be
+performed only once at process startup time, and execution aborted early
+if the required helpers are not provided by the kernel version that
+process is running on.

+Definition:
+
+  This field contains the number of helpers being implemented by the

+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

+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.

 1. Allocate a DMA slave channel
-Channel allocation is slightly different in the slave DMA context, client
-drivers typically need a channel from a particular DMA controller only and even
-in some cases a specific channel is desired. To request a channel
-dma_request_channel() API is used.
-
-Interface:
-struct dma_chan *dma_request_channel(dma_cap_mask_t mask,
-		dma_filter_fn filter_fn,
-		void *filter_param);
-where dma_filter_fn is defined as:
-typedef bool (*dma_filter_fn)(struct dma_chan *chan, void *filter_param);
-
-When the optional 'filter_fn' parameter is set to NULL dma_request_channel
-simply returns the first channel that satisfies the capability mask.  Otherwise,
-when the mask parameter is insufficient for specifying the necessary channel,
-the filter_fn routine can be used to disposition the available channels in the
-system. The filter_fn routine is called once for each free channel in the
-system.  Upon seeing a suitable channel filter_fn returns DMA_ACK which flags
-that channel to be the return value from dma_request_channel.  A channel
-allocated via this interface is exclusive to the caller, until
-dma_release_channel() is called.

+

+			void *filter_param);
+   where dma_filter_fn is defined as:
+	typedef bool (*dma_filter_fn)(struct dma_chan *chan, void *filter_param);
+
+   The 'filter_fn' parameter is optional, but highly recommended for

+
+   When the optional 'filter_fn' parameter is NULL, dma_request_channel()

+
+   Otherwise, the 'filter_fn' routine will be called once for each free

+   return 'true' when the desired DMA channel is found.
+
+   A channel allocated via this interface is exclusive to the caller,
+   until dma_release_channel() is called.
 
 2. Set slave and controller specific parameters
-Next step is always to pass some specific information to the DMA driver. Most of
-the generic information which a slave DMA can use is in struct dma_slave_config.
-It allows the clients to specify DMA direction, DMA addresses, bus widths, DMA
-burst lengths etc. If some DMA controllers have more parameters to be sent then
-they should try to embed struct dma_slave_config in their controller specific
-structure. That gives flexibility to client to pass more parameters, if
-required.

+
+   Interface:

+		unsigned int sg_len, enum dma_data_direction direction,

 		struct dma_chan *chan, dma_addr_t buf_addr, size_t buf_len,
 		size_t period_len, enum dma_data_direction direction);
 
-4. Submit the transaction and wait for callback notification
-To schedule the transaction to be scheduled by dma device, the "descriptor"
-returned in above (3) needs to be submitted.
-To tell the dma driver that a transaction is ready to be serviced, the
-descriptor->submit() callback needs to be invoked. This chains the descriptor to
-the pending queue.
-The transactions in the pending queue can be activated by calling the
-issue_pending API. If channel is idle then the first transaction in queue is
-started and subsequent ones queued up.
-On completion of the DMA operation the next in queue is submitted and a tasklet
-triggered. The tasklet would then call the client driver completion callback
-routine for notification, if set.
-Interface:
-void dma_async_issue_pending(struct dma_chan *chan);
-
-==============================================================================
-
-Additional usage notes for dma driver writers
-1/ Although DMA engine specifies that completion callback routines cannot submit
-any new operations, but typically for slave DMA subsequent transaction may not
-be available for submit prior to callback routine being called. This requirement
-is not a requirement for DMA-slave devices. But they should take care to drop
-the spin-lock they might be holding before calling the callback routine
+   The peripheral driver is expected to have mapped the scatterlist for
+   the DMA operation prior to calling device_prep_slave_sg, and must
+   keep the scatterlist mapped until the DMA operation has completed.
+   The scatterlist must be mapped using the DMA struct device.  So,
+   normal setup should look like this:
+
+	nr_sg = dma_map_sg(chan->device->dev, sgl, sg_len);
+	if (nr_sg == 0)
+		/* error */
+
+	desc = chan->device->device_prep_slave_sg(chan, sgl, nr_sg,
+			direction, flags);
+
+   Once a descriptor has been obtained, the callback information can be
+   added and the descriptor must then be submitted.  Some DMA engine
+   drivers may hold a spinlock between a successful preparation and
+   submission so it is important that these two operations are closely
+   paired.
+
+   Note:
+	Although the async_tx API specifies that completion callback
+	routines cannot submit any new operations, this is not the
+	case for slave/cyclic DMA.
+
+	For slave DMA, the subsequent transaction may not be available
+	for submission prior to callback function being invoked, so
+	slave DMA callbacks are permitted to prepare and submit a new
+	transaction.
+
+	For cyclic DMA, a callback function may wish to terminate the
+	DMA via dmaengine_terminate_all().
+
+	Therefore, it is important that DMA engine drivers drop any
+	locks before calling the callback function which may cause a
+	deadlock.
+
+	Note that callbacks will always be invoked from the DMA
+	engines tasklet, never from interrupt context.
+
+4. Submit the transaction
+
+   Once the descriptor has been prepared and the callback information
+   added, it must be placed on the DMA engine drivers pending queue.
+
+   Interface:
+	dma_cookie_t dmaengine_submit(struct dma_async_tx_descriptor *desc)
+
+   This returns a cookie can be used to check the progress of DMA engine
+   activity via other DMA engine calls not covered in this document.
+
+   dmaengine_submit() will not start the DMA operation, it merely adds
+   it to the pending queue.  For this, see step 5, dma_async_issue_pending.
+
+5. Issue pending DMA requests and wait for callback notification
+
+   The transactions in the pending queue can be activated by calling the
+   issue_pending API. If channel is idle then the first transaction in
+   queue is started and subsequent ones queued up.
+
+   On completion of each DMA operation, the next in queue is started and
+   a tasklet triggered. The tasklet will then call the client driver
+   completion callback routine for notification, if set.
+
+   Interface:
+	void dma_async_issue_pending(struct dma_chan *chan);
+
+Further APIs:
+
+1. int dmaengine_terminate_all(struct dma_chan *chan)
+
+   This causes all activity for the DMA channel to be stopped, and may
+   discard data in the DMA FIFO which hasn't been fully transferred.
+   No callback functions will be called for any incomplete transfers.
+
+2. int dmaengine_pause(struct dma_chan *chan)
+
+   This pauses activity on the DMA channel without data loss.
+
+3. int dmaengine_resume(struct dma_chan *chan)
+
+   Resume a previously paused DMA channel.  It is invalid to resume a
+   channel which is not currently paused.
+
+4. enum dma_status dma_async_is_tx_complete(struct dma_chan *chan,
+        dma_cookie_t cookie, dma_cookie_t *last, dma_cookie_t *used)
+
+   This can be used to check the status of the channel.  Please see
+   the documentation in include/linux/dmaengine.h for a more complete
+   description of this API.
+
+   This can be used in conjunction with dma_async_is_complete() and
+   the cookie returned from 'descriptor->submit()' to check for
+   completion of a specific DMA transaction.
+
+   Note:
+	Not all DMA engine drivers can return reliable information for
+	a running DMA channel.  It is recommended that DMA engine users
+	pause or stop (via dmaengine_terminate_all) the channel before
+	using this API.

+Description
+-----------
+
+The LM95245 is an 11-bit digital temperature sensor with a 2-wire System
+Management Bus (SMBus) interface and TruTherm technology that can monitor
+the temperature of a remote diode as well as its own temperature.
+The LM95245 can be used to very accurately monitor the temperature of
+external devices such as microprocessors.
+
+All temperature values are given in millidegrees Celsius. Local temperature
+is given within a range of -127 to +127.875 degrees. Remote temperatures are
+given within a range of -127 to +255 degrees. Resolution depends on
+temperature input and range.
+
+Each sensor has its own critical limit, but the hysteresis is common to all
+two channels.
+
+The lm95245 driver can change its update interval to a fixed set of values.
+It will round up to the next selectable interval. See the datasheet for exact
+values. Reading sensor values more often will do no harm, but will return
+'old' values.

+
+Description
+-----------
+
+This driver implements support for the Maxim MAX1668, MAX1805 and MAX1989
+chips.
+
+The three devices are very similar, but the MAX1805 has a reduced feature
+set; only two remote temperature inputs vs the four avaible on the other
+two ICs.
+
+The driver is able to distinguish between the devices and creates sysfs
+entries as follows:
+
+MAX1805, MAX1668 and MAX1989:
+
+temp1_input     ro local (ambient) temperature
+temp1_max       rw local temperature maximum threshold for alarm

+temp1_min       rw local temperature minimum threshold for alarm
+temp1_min_alarm ro local temperature minimum threshold alarm
+temp2_input     ro remote temperature 1
+temp2_max       rw remote temperature 1 maximum threshold for alarm
+temp2_max_alarm ro remote temperature 1 maximum threshold alarm
+temp2_min       rw remote temperature 1 minimum threshold for alarm
+temp2_min_alarm ro remote temperature 1 minimum threshold alarm
+temp3_input     ro remote temperature 2
+temp3_max       rw remote temperature 2 maximum threshold for alarm
+temp3_max_alarm ro remote temperature 2 maximum threshold alarm
+temp3_min       rw remote temperature 2 minimum threshold for alarm
+temp3_min_alarm ro remote temperature 2 minimum threshold alarm
+
+MAX1668 and MAX1989 only:
+temp4_input     ro remote temperature 3
+temp4_max       rw remote temperature 3 maximum threshold for alarm
+temp4_max_alarm ro remote temperature 3 maximum threshold alarm
+temp4_min       rw remote temperature 3 minimum threshold for alarm
+temp4_min_alarm ro remote temperature 3 minimum threshold alarm
+temp5_input     ro remote temperature 4
+temp5_max       rw remote temperature 4 maximum threshold for alarm
+temp5_max_alarm ro remote temperature 4 maximum threshold alarm
+temp5_min       rw remote temperature 4 minimum threshold for alarm
+temp5_min_alarm ro remote temperature 4 minimum threshold alarm
+
+Module Parameters

+
+Description
+-----------
+
+The NTC thermistor is a simple thermistor that requires users to provide the
+resistance and lookup the corresponding compensation table to get the
+temperature input.
+
+The NTC driver provides lookup tables with a linear approximation function
+and four circuit models with an option not to use any of the four models.
+
+The four circuit models provided are:
+

+
+When one of the four circuit models is used, read_uV, pullup_uV, pullup_ohm,
+pulldown_ohm, and connect should be provided. When none of the four models
+are suitable or the user can get the resistance directly, the user should

+Author: Hans de Goede <hdegoede@redhat.com>
+
+
+Description
+-----------
+
+SMSC SCH5636 Super I/O chips include an embedded microcontroller for
+hardware monitoring solutions, allowing motherboard manufacturers to create
+their own custom hwmon solution based upon the SCH5636.
+
+Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636 based
+hwmon solution. The sch5636 driver runs a sanity check on loading to ensure
+it is dealing with a Fujitsu Theseus and not with another custom SCH5636 based
+hwmon solution.
+
+The Fujitsu Theseus can monitor up to 5 voltages, 8 fans and 16
+temperatures. Note that the driver detects how many fan headers /
+temperature sensors are actually implemented on the motherboard, so you will
+likely see fewer temperature and fan inputs.
+
+An application note describing the Theseus' registers, as well as an
+application note describing the protocol for communicating with the
+microcontroller is available upon request. Please mail me if you want a copy.

+The packet format is exactly the same for two finger touch, except the hardware

+the second packet has data for the second finger. So for two finger touch a
+total of 12 bytes are sent.

+7.2 Native absolute mode 6 byte packet format
+    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+v4 hardware is a true multitouch touchpad, capable of tracking up to 5 fingers.
+Unfortunately, due to PS/2's limited bandwidth, its packet format is rather
+complex.
+
+Whenever the numbers or identities of the fingers changes, the hardware sends a
+status packet to indicate how many and which fingers is on touchpad, followed by
+head packets or motion packets. A head packet contains data of finger id, finger
+position (absolute x, y values), width, and pressure. A motion packet contains
+two fingers' position delta.
+
+For example, when status packet tells there are 2 fingers on touchpad, then we
+can expect two following head packets. If the finger status doesn't change,
+the following packets would be motion packets, only sending delta of finger
+position, until we receive a status packet.
+
+One exception is one finger touch. when a status packet tells us there is only
+one finger, the hardware would just send head packets afterwards.

 end.  Upon receiving an MT event, one simply updates the appropriate
 attribute of the current slot.
 
+Some devices identify and/or track more contacts than they can report to the
+driver.  A driver for such a device should associate one type B slot with each
+contact that is reported by the hardware.  Whenever the identity of the
+contact associated with a slot changes, the driver should invalidate that
+slot by changing its ABS_MT_TRACKING_ID.  If the hardware signals that it is
+tracking more contacts than it is currently reporting, the driver should use
+a BTN_TOOL_*TAP event to inform userspace of the total number of contacts
+being tracked by the hardware at that moment.  The driver should do this by
+explicitly sending the corresponding BTN_TOOL_*TAP event and setting
+use_count to false when calling input_mt_report_pointer_emulation().
+The driver should only advertise as many slots as the hardware can report.
+Userspace can detect that a driver can report more total contacts than slots
+by noting that the largest supported BTN_TOOL_*TAP event is larger than the
+total number of type B slots reported in the absinfo for the ABS_MT_SLOT axis.

-       can make browsing source codes of Linux kernel easier than you can
-       imagine. You can select between multiple versions of kernel (e.g.
-       0.01, 1.0.0, 2.0.33, 2.0.34pre13, 2.0.0, 2.1.101 etc.). With LSD
-       you can search Linux kernel (fulltext, macros, types, functions
-       and variables) and LSD can generate patches for you on the fly
-       (files, directories or kernel)".

+Rationale
+=========
+
+How significant is the cache maintenance overhead?
+It depends. Fast eMMC and multiple cache levels with speculative cache
+pre-fetch makes the cache overhead relatively significant. If the DMA
+preparations for the next request are done in parallel with the current
+transfer, the DMA preparation overhead would not affect the MMC performance.
+The intention of non-blocking (asynchronous) MMC requests is to minimize the
+time between when an MMC request ends and another MMC request begins.
+Using mmc_wait_for_req(), the MMC controller is idle while dma_map_sg and
+dma_unmap_sg are processing. Using non-blocking MMC requests makes it
+possible to prepare the caches for next job in parallel with an active
+MMC request.
+
+MMC block driver
+================
+
+The mmc_blk_issue_rw_rq() in the MMC block driver is made non-blocking.
+The increase in throughput is proportional to the time it takes to
+prepare (major part of preparations are dma_map_sg() and dma_unmap_sg())
+a request and how fast the memory is. The faster the MMC/SD is the
+more significant the prepare request time becomes. Roughly the expected
+performance gain is 5% for large writes and 10% on large reads on a L2 cache
+platform. In power save mode, when clocks run on a lower frequency, the DMA
+preparation may cost even more. As long as these slower preparations are run
+in parallel with the transfer performance won't be affected.
+
+Details on measurements from IOZone and mmc_test
+================================================
+
+https://wiki.linaro.org/WorkingGroups/Kernel/Specs/StoragePerfMMC-async-req
+
+MMC core API extension
+======================
+
+There is one new public function mmc_start_req().
+It starts a new MMC command request for a host. The function isn't
+truly non-blocking. If there is an ongoing async request it waits
+for completion of that request and starts the new one and returns. It
+doesn't wait for the new request to complete. If there is no ongoing
+request it starts the new request and returns immediately.
+
+MMC host extensions
+===================
+
+There are two optional members in the mmc_host_ops -- pre_req() and
+post_req() -- that the host driver may implement in order to move work
+to before and after the actual mmc_host_ops.request() function is called.
+In the DMA case pre_req() may do dma_map_sg() and prepare the DMA
+descriptor, and post_req() runs the dma_unmap_sg().
+
+Optimize for the first request
+==============================
+
+The first request in a series of requests can't be prepared in parallel
+with the previous transfer, since there is no previous request.
+The argument is_first_req in pre_req() indicates that there is no previous
+request. The host driver may optimize for this scenario to minimize
+the performance loss. A way to optimize for this is to split the current
+request in two chunks, prepare the first chunk and start the request,
+and finally prepare the second chunk and start the transfer.
+
+Pseudocode to handle is_first_req scenario with minimal prepare overhead:
+
+if (is_first_req && req->size > threshold)
+   /* start MMC transfer for the complete transfer size */
+   mmc_start_command(MMC_CMD_TRANSFER_FULL_SIZE);
+
+   /*
+    * Begin to prepare DMA while cmd is being processed by MMC.
+    * The first chunk of the request should take the same time
+    * to prepare as the "MMC process command time".
+    * If prepare time exceeds MMC cmd time
+    * the transfer is delayed, guesstimate max 4k as first chunk size.
+    */
+    prepare_1st_chunk_for_dma(req);
+    /* flush pending desc to the DMAC (dmaengine.h) */
+    dma_issue_pending(req->dma_desc);
+
+    prepare_2nd_chunk_for_dma(req);
+    /*
+     * The second issue_pending should be called before MMC runs out
+     * of the first chunk. If the MMC runs out of the first data chunk
+     * before this call, the transfer is delayed.

+Netdev features mess and how to get out from it alive
+=====================================================
+
+Author:
+	Michał Mirosław <mirq-linux@rere.qmqm.pl>
+
+
+
+ Part I: Feature sets
+======================
+
+Long gone are the days when a network card would just take and give packets
+verbatim.  Today's devices add multiple features and bugs (read: offloads)
+that relieve an OS of various tasks like generating and checking checksums,
+splitting packets, classifying them.  Those capabilities and their state
+are commonly referred to as netdev features in Linux kernel world.
+
+There are currently three sets of features relevant to the driver, and
+one used internally by network core:
+
+ 1. netdev->hw_features set contains features whose state may possibly
+    be changed (enabled or disabled) for a particular device by user's
+    request.  This set should be initialized in ndo_init callback and not
+    changed later.
+
+ 2. netdev->features set contains features which are currently enabled
+    for a device.  This should be changed only by network core or in
+    error paths of ndo_set_features callback.
+
+ 3. netdev->vlan_features set contains features whose state is inherited
+    by child VLAN devices (limits netdev->features set).  This is currently
+    used for all VLAN devices whether tags are stripped or inserted in
+    hardware or software.
+
+ 4. netdev->wanted_features set contains feature set requested by user.
+    This set is filtered by ndo_fix_features callback whenever it or
+    some device-specific conditions change. This set is internal to
+    networking core and should not be referenced in drivers.
+
+
+
+ Part II: Controlling enabled features
+=======================================
+
+When current feature set (netdev->features) is to be changed, new set
+is calculated and filtered by calling ndo_fix_features callback
+and netdev_fix_features(). If the resulting set differs from current
+set, it is passed to ndo_set_features callback and (if the callback
+returns success) replaces value stored in netdev->features.
+NETDEV_FEAT_CHANGE notification is issued after that whenever current
+set might have changed.
+
+The following events trigger recalculation:
+ 1. device's registration, after ndo_init returned success
+ 2. user requested changes in features state
+ 3. netdev_update_features() is called
+
+ndo_*_features callbacks are called with rtnl_lock held. Missing callbacks
+are treated as always returning success.
+
+A driver that wants to trigger recalculation must do so by calling
+netdev_update_features() while holding rtnl_lock. This should not be done
+from ndo_*_features callbacks. netdev->features should not be modified by
+driver except by means of ndo_fix_features callback.
+
+
+
+ Part III: Implementation hints
+================================
+
+ * ndo_fix_features:
+
+All dependencies between features should be resolved here. The resulting
+set can be reduced further by networking core imposed limitations (as coded
+in netdev_fix_features()). For this reason it is safer to disable a feature
+when its dependencies are not met instead of forcing the dependency on.
+
+This callback should not modify hardware nor driver state (should be
+stateless).  It can be called multiple times between successive
+ndo_set_features calls.
+
+Callback must not alter features contained in NETIF_F_SOFT_FEATURES or
+NETIF_F_NEVER_CHANGE sets. The exception is NETIF_F_VLAN_CHALLENGED but
+care must be taken as the change won't affect already configured VLANs.
+
+ * ndo_set_features:
+
+Hardware should be reconfigured to match passed feature set. The set
+should not be altered unless some error condition happens that can't
+be reliably detected in ndo_fix_features. In this case, the callback
+should update netdev->features to match resulting hardware state.
+Errors returned are not (and cannot be) propagated anywhere except dmesg.
+(Note: successful return is zero, >0 means silent error.)
+
+
+
+ Part IV: Features
+===================
+
+For current list of features, see include/linux/netdev_features.h.
+This section describes semantics of some of them.
+
+ * Transmit checksumming
+
+For complete description, see comments near the top of include/linux/skbuff.h.
+
+Note: NETIF_F_HW_CSUM is a superset of NETIF_F_IP_CSUM + NETIF_F_IPV6_CSUM.
+It means that device can fill TCP/UDP-like checksum anywhere in the packets
+whatever headers there might be.
+
+ * Transmit TCP segmentation offload
+
+NETIF_F_TSO_ECN means that hardware can properly split packets with CWR bit
+set, be it TCPv4 (when NETIF_F_TSO is enabled) or TCPv6 (NETIF_F_TSO6).
+
+ * Transmit DMA from high memory
+
+On platforms where this is relevant, NETIF_F_HIGHDMA signals that
+ndo_start_xmit can handle skbs with frags in high memory.
+
+ * Transmit scatter-gather
+
+Those features say that ndo_start_xmit can handle fragmented skbs:
+NETIF_F_SG --- paged skbs (skb_shinfo()->frags), NETIF_F_FRAGLIST ---
+chained skbs (skb->next/prev list).
+
+ * Software features
+
+Features contained in NETIF_F_SOFT_FEATURES are features of networking
+stack. Driver should not change behaviour based on them.
+
+ * LLTX driver (deprecated for hardware drivers)
+
+NETIF_F_LLTX should be set in drivers that implement their own locking in
+transmit path or don't need locking at all (e.g. software tunnels).
+In ndo_start_xmit, it is recommended to use a try_lock and return
+NETDEV_TX_LOCKED when the spin lock fails.  The locking should also properly
+protect against other callbacks (the rules you need to find out).
+
+Don't use it for new drivers.
+
+ * netns-local device
+
+NETIF_F_NETNS_LOCAL is set for devices that are not allowed to move between
+network namespaces (e.g. loopback).
+
+Don't use it in drivers.
+
+ * VLAN challenged
+
+NETIF_F_VLAN_CHALLENGED should be set for devices which can't cope with VLAN
+headers. Some drivers set this because the cards can't handle the bigger MTU.
+[FIXME: Those cases could be fixed in VLAN code by allowing only reduced-MTU
+VLANs. This may be not useful, though.]

+Linux NFC subsystem
+===================
+
+The Near Field Communication (NFC) subsystem is required to standardize the
+NFC device drivers development and to create an unified userspace interface.
+
+This document covers the architecture overview, the device driver interface
+description and the userspace interface description.
+
+Architecture overview
+---------------------
+
+The NFC subsystem is responsible for:
+      - NFC adapters management;
+      - Polling for targets;
+      - Low-level data exchange;
+
+The subsystem is divided in some parts. The 'core' is responsible for
+providing the device driver interface. On the other side, it is also
+responsible for providing an interface to control operations and low-level
+data exchange.
+
+The control operations are available to userspace via generic netlink.
+
+The low-level data exchange interface is provided by the new socket family
+PF_NFC. The NFC_SOCKPROTO_RAW performs raw communication with NFC targets.
+
+
+             +--------------------------------------+

+                                    +-----------+
+
+Device Driver Interface
+-----------------------
+
+When registering on the NFC subsystem, the device driver must inform the core
+of the set of supported NFC protocols and the set of ops callbacks. The ops
+callbacks that must be implemented are the following:
+
+* start_poll - setup the device to poll for targets
+* stop_poll - stop on progress polling operation
+* activate_target - select and initialize one of the targets found
+* deactivate_target - deselect and deinitialize the selected target
+* data_exchange - send data and receive the response (transceive operation)
+
+Userspace interface
+--------------------
+
+The userspace interface is divided in control operations and low-level data
+exchange operation.
+
+CONTROL OPERATIONS:
+
+Generic netlink is used to implement the interface to the control operations.
+The operations are composed by commands and events, all listed below:
+
+* NFC_CMD_GET_DEVICE - get specific device info or dump the device list
+* NFC_CMD_START_POLL - setup a specific device to polling for targets
+* NFC_CMD_STOP_POLL - stop the polling operation in a specific device
+* NFC_CMD_GET_TARGET - dump the list of targets found by a specific device
+
+* NFC_EVENT_DEVICE_ADDED - reports an NFC device addition
+* NFC_EVENT_DEVICE_REMOVED - reports an NFC device removal
+* NFC_EVENT_TARGETS_FOUND - reports START_POLL results when 1 or more targets
+are found
+
+The user must call START_POLL to poll for NFC targets, passing the desired NFC
+protocols through NFC_ATTR_PROTOCOLS attribute. The device remains in polling
+state until it finds any target. However, the user can stop the polling
+operation by calling STOP_POLL command. In this case, it will be checked if
+the requester of STOP_POLL is the same of START_POLL.
+
+If the polling operation finds one or more targets, the event TARGETS_FOUND is
+sent (including the device id). The user must call GET_TARGET to get the list of
+all targets found by such device. Each reply message has target attributes with
+relevant information such as the supported NFC protocols.
+
+All polling operations requested through one netlink socket are stopped when
+it's closed.
+
+LOW-LEVEL DATA EXCHANGE:
+
+The userspace must use PF_NFC sockets to perform any data communication with
+targets. All NFC sockets use AF_NFC:
+
+struct sockaddr_nfc {
+       sa_family_t sa_family;
+       __u32 dev_idx;
+       __u32 target_idx;
+       __u32 nfc_protocol;
+};
+
+To establish a connection with one target, the user must create an
+NFC_SOCKPROTO_RAW socket and call the 'connect' syscall with the sockaddr_nfc
+struct correctly filled. All information comes from NFC_EVENT_TARGETS_FOUND
+netlink event. As a target can support more than one NFC protocol, the user
+must inform which protocol it wants to use.
+
+Internally, 'connect' will result in an activate_target call to the driver.
+When the socket is closed, the target is deactivated.
+
+The data format exchanged through the sockets is NFC protocol dependent. For
+instance, when communicating with MIFARE tags, the data exchanged are MIFARE
+commands and their responses.
+
+The first received package is the response to the first sent package and so
+on. In order to allow valid "empty" responses, every data received has a NULL
+header of 1 byte.

+Scaling in the Linux Networking Stack
+
+
+Introduction
+============
+
+This document describes a set of complementary techniques in the Linux
+networking stack to increase parallelism and improve performance for
+multi-processor systems.
+
+The following technologies are described:
+
+  RSS: Receive Side Scaling
+  RPS: Receive Packet Steering
+  RFS: Receive Flow Steering
+  Accelerated Receive Flow Steering
+  XPS: Transmit Packet Steering
+
+
+RSS: Receive Side Scaling
+=========================
+
+Contemporary NICs support multiple receive and transmit descriptor queues
+(multi-queue). On reception, a NIC can send different packets to different
+queues to distribute processing among CPUs. The NIC distributes packets by
+applying a filter to each packet that assigns it to one of a small number
+of logical flows. Packets for each flow are steered to a separate receive
+queue, which in turn can be processed by separate CPUs. This mechanism is
+generally known as “Receive-side Scaling” (RSS). The goal of RSS and
+the other scaling techniques to increase performance uniformly.
+Multi-queue distribution can also be used for traffic prioritization, but
+that is not the focus of these techniques.
+
+The filter used in RSS is typically a hash function over the network
+and/or transport layer headers-- for example, a 4-tuple hash over
+IP addresses and TCP ports of a packet. The most common hardware
+implementation of RSS uses a 128-entry indirection table where each entry
+stores a queue number. The receive queue for a packet is determined
+by masking out the low order seven bits of the computed hash for the
+packet (usually a Toeplitz hash), taking this number as a key into the
+indirection table and reading the corresponding value.
+
+Some advanced NICs allow steering packets to queues based on
+programmable filters. For example, webserver bound TCP port 80 packets
+can be directed to their own receive queue. Such “n-tuple” filters can
+be configured from ethtool (--config-ntuple).
+
+==== RSS Configuration
+
+The driver for a multi-queue capable NIC typically provides a kernel
+module parameter for specifying the number of hardware queues to
+configure. In the bnx2x driver, for instance, this parameter is called
+num_queues. A typical RSS configuration would be to have one receive queue
+for each CPU if the device supports enough queues, or otherwise at least
+one for each memory domain, where a memory domain is a set of CPUs that
+share a particular memory level (L1, L2, NUMA node, etc.).
+
+The indirection table of an RSS device, which resolves a queue by masked
+hash, is usually programmed by the driver at initialization. The
+default mapping is to distribute the queues evenly in the table, but the
+indirection table can be retrieved and modified at runtime using ethtool
+commands (--show-rxfh-indir and --set-rxfh-indir). Modifying the
+indirection table could be done to give different queues different
+relative weights.
+
+== RSS IRQ Configuration
+
+Each receive queue has a separate IRQ associated with it. The NIC triggers
+this to notify a CPU when new packets arrive on the given queue. The
+signaling path for PCIe devices uses message signaled interrupts (MSI-X),
+that can route each interrupt to a particular CPU. The active mapping
+of queues to IRQs can be determined from /proc/interrupts. By default,
+an IRQ may be handled on any CPU. Because a non-negligible part of packet
+processing takes place in receive interrupt handling, it is advantageous
+to spread receive interrupts between CPUs. To manually adjust the IRQ
+affinity of each interrupt see Documentation/IRQ-affinity. Some systems
+will be running irqbalance, a daemon that dynamically optimizes IRQ
+assignments and as a result may override any manual settings.
+
+== Suggested Configuration
+
+RSS should be enabled when latency is a concern or whenever receive
+interrupt processing forms a bottleneck. Spreading load between CPUs
+decreases queue length. For low latency networking, the optimal setting
+is to allocate as many queues as there are CPUs in the system (or the
+NIC maximum, if lower). The most efficient high-rate configuration
+is likely the one with the smallest number of receive queues where no
+receive queue overflows due to a saturated CPU, because in default
+mode with interrupt coalescing enabled, the aggregate number of
+interrupts (and thus work) grows with each additional queue.
+
+Per-cpu load can be observed using the mpstat utility, but note that on
+processors with hyperthreading (HT), each hyperthread is represented as
+a separate CPU. For interrupt handling, HT has shown no benefit in
+initial tests, so limit the number of queues to the number of CPU cores
+in the system.
+
+
+RPS: Receive Packet Steering
+============================
+
+Receive Packet Steering (RPS) is logically a software implementation of
+RSS. Being in software, it is necessarily called later in the datapath.
+Whereas RSS selects the queue and hence CPU that will run the hardware
+interrupt handler, RPS selects the CPU to perform protocol processing
+above the interrupt handler. This is accomplished by placing the packet
+on the desired CPU’s backlog queue and waking up the CPU for processing.
+RPS has some advantages over RSS: 1) it can be used with any NIC,
+2) software filters can easily be added to hash over new protocols,
+3) it does not increase hardware device interrupt rate (although it does
+introduce inter-processor interrupts (IPIs)).
+
+RPS is called during bottom half of the receive interrupt handler, when
+a driver sends a packet up the network stack with netif_rx() or
+netif_receive_skb(). These call the get_rps_cpu() function, which
+selects the queue that should process a packet.
+
+The first step in determining the target CPU for RPS is to calculate a
+flow hash over the packet’s addresses or ports (2-tuple or 4-tuple hash
+depending on the protocol). This serves as a consistent hash of the
+associated flow of the packet. The hash is either provided by hardware
+or will be computed in the stack. Capable hardware can pass the hash in
+the receive descriptor for the packet; this would usually be the same
+hash used for RSS (e.g. computed Toeplitz hash). The hash is saved in
+skb->rx_hash and can be used elsewhere in the stack as a hash of the
+packet’s flow.
+
+Each receive hardware queue has an associated list of CPUs to which
+RPS may enqueue packets for processing. For each received packet,
+an index into the list is computed from the flow hash modulo the size
+of the list. The indexed CPU is the target for processing the packet,
+and the packet is queued to the tail of that CPU’s backlog queue. At
+the end of the bottom half routine, IPIs are sent to any CPUs for which
+packets have been queued to their backlog queue. The IPI wakes backlog
+processing on the remote CPU, and any queued packets are then processed
+up the networking stack.
+
+==== RPS Configuration
+
+RPS requires a kernel compiled with the CONFIG_RPS kconfig symbol (on
+by default for SMP). Even when compiled in, RPS remains disabled until
+explicitly configured. The list of CPUs to which RPS may forward traffic
+can be configured for each receive queue using a sysfs file entry:
+
+ /sys/class/net/<dev>/queues/rx-<n>/rps_cpus
+
+This file implements a bitmap of CPUs. RPS is disabled when it is zero
+(the default), in which case packets are processed on the interrupting
+CPU. Documentation/IRQ-affinity.txt explains how CPUs are assigned to
+the bitmap.
+
+== Suggested Configuration
+
+For a single queue device, a typical RPS configuration would be to set
+the rps_cpus to the CPUs in the same memory domain of the interrupting
+CPU. If NUMA locality is not an issue, this could also be all CPUs in
+the system. At high interrupt rate, it might be wise to exclude the
+interrupting CPU from the map since that already performs much work.
+
+For a multi-queue system, if RSS is configured so that a hardware
+receive queue is mapped to each CPU, then RPS is probably redundant
+and unnecessary. If there are fewer hardware queues than CPUs, then
+RPS might be beneficial if the rps_cpus for each queue are the ones that
+share the same memory domain as the interrupting CPU for that queue.
+
+
+RFS: Receive Flow Steering
+==========================
+
+While RPS steers packets solely based on hash, and thus generally
+provides good load distribution, it does not take into account
+application locality. This is accomplished by Receive Flow Steering
+(RFS). The goal of RFS is to increase datacache hitrate by steering
+kernel processing of packets to the CPU where the application thread
+consuming the packet is running. RFS relies on the same RPS mechanisms
+to enqueue packets onto the backlog of another CPU and to wake up that
+CPU.
+
+In RFS, packets are not forwarded directly by the value of their hash,
+but the hash is used as index into a flow lookup table. This table maps
+flows to the CPUs where those flows are being processed. The flow hash
+(see RPS section above) is used to calculate the index into this table.
+The CPU recorded in each entry is the one which last processed the flow.
+If an entry does not hold a valid CPU, then packets mapped to that entry
+are steered using plain RPS. Multiple table entries may point to the
+same CPU. Indeed, with many flows and few CPUs, it is very likely that
+a single application thread handles flows with many different flow hashes.
+
+rps_sock_table is a global flow table that contains the *desired* CPU for
+flows: the CPU that is currently processing the flow in userspace. Each
+table value is a CPU index that is updated during calls to recvmsg and
+sendmsg (specifically, inet_recvmsg(), inet_sendmsg(), inet_sendpage()
+and tcp_splice_read()).
+
+When the scheduler moves a thread to a new CPU while it has outstanding
+receive packets on the old CPU, packets may arrive out of order. To
+avoid this, RFS uses a second flow table to track outstanding packets
+for each flow: rps_dev_flow_table is a table specific to each hardware
+receive queue of each device. Each table value stores a CPU index and a
+counter. The CPU index represents the *current* CPU onto which packets
+for this flow are enqueued for further kernel processing. Ideally, kernel
+and userspace processing occur on the same CPU, and hence the CPU index
+in both tables is identical. This is likely false if the scheduler has
+recently migrated a userspace thread while the kernel still has packets
+enqueued for kernel processing on the old CPU.
+
+The counter in rps_dev_flow_table values records the length of the current
+CPU's backlog when a packet in this flow was last enqueued. Each backlog
+queue has a head counter that is incremented on dequeue. A tail counter
+is computed as head counter + queue length. In other words, the counter
+in rps_dev_flow_table[i] records the last element in flow i that has
+been enqueued onto the currently designated CPU for flow i (of course,
+entry i is actually selected by hash and multiple flows may hash to the
+same entry i).
+
+And now the trick for avoiding out of order packets: when selecting the
+CPU for packet processing (from get_rps_cpu()) the rps_sock_flow table
+and the rps_dev_flow table of the queue that the packet was received on
+are compared. If the desired CPU for the flow (found in the
+rps_sock_flow table) matches the current CPU (found in the rps_dev_flow
+table), the packet is enqueued onto that CPU’s backlog. If they differ,
+the current CPU is updated to match the desired CPU if one of the
+following is true:
+
+- The current CPU's queue head counter >= the recorded tail counter
+  value in rps_dev_flow[i]
+- The current CPU is unset (equal to NR_CPUS)
+- The current CPU is offline
+
+After this check, the packet is sent to the (possibly updated) current
+CPU. These rules aim to ensure that a flow only moves to a new CPU when
+there are no packets outstanding on the old CPU, as the outstanding
+packets could arrive later than those about to be processed on the new
+CPU.
+
+==== RFS Configuration
+
+RFS is only available if the kconfig symbol CONFIG_RFS is enabled (on
+by default for SMP). The functionality remains disabled until explicitly
+configured. The number of entries in the global flow table is set through:
+
+ /proc/sys/net/core/rps_sock_flow_entries
+
+The number of entries in the per-queue flow table are set through:
+
+ /sys/class/net/<dev>/queues/tx-<n>/rps_flow_cnt
+
+== Suggested Configuration
+
+Both of these need to be set before RFS is enabled for a receive queue.
+Values for both are rounded up to the nearest power of two. The
+suggested flow count depends on the expected number of active connections
+at any given time, which may be significantly less than the number of open
+connections. We have found that a value of 32768 for rps_sock_flow_entries
+works fairly well on a moderately loaded server.
+
+For a single queue device, the rps_flow_cnt value for the single queue
+would normally be configured to the same value as rps_sock_flow_entries.
+For a multi-queue device, the rps_flow_cnt for each queue might be
+configured as rps_sock_flow_entries / N, where N is the number of
+queues. So for instance, if rps_flow_entries is set to 32768 and there
+are 16 configured receive queues, rps_flow_cnt for each queue might be
+configured as 2048.
+
+
+Accelerated RFS
+===============
+
+Accelerated RFS is to RFS what RSS is to RPS: a hardware-accelerated load
+balancing mechanism that uses soft state to steer flows based on where
+the application thread consuming the packets of each flow is running.
+Accelerated RFS should perform better than RFS since packets are sent
+directly to a CPU local to the thread consuming the data. The target CPU
+will either be the same CPU where the application runs, or at least a CPU
+which is local to the application thread’s CPU in the cache hierarchy.
+
+To enable accelerated RFS, the networking stack calls the
+ndo_rx_flow_steer driver function to communicate the desired hardware
+queue for packets matching a particular flow. The network stack
+automatically calls this function every time a flow entry in
+rps_dev_flow_table is updated. The driver in turn uses a device specific
+method to program the NIC to steer the packets.
+
+The hardware queue for a flow is derived from the CPU recorded in
+rps_dev_flow_table. The stack consults a CPU to hardware queue map which
+is maintained by the NIC driver. This is an auto-generated reverse map of
+the IRQ affinity table shown by /proc/interrupts. Drivers can use
+functions in the cpu_rmap (“CPU affinity reverse map”) kernel library
+to populate the map. For each CPU, the corresponding queue in the map is
+set to be one whose processing CPU is closest in cache locality.
+
+==== Accelerated RFS Configuration
+
+Accelerated RFS is only available if the kernel is compiled with
+CONFIG_RFS_ACCEL and support is provided by the NIC device and driver.
+It also requires that ntuple filtering is enabled via ethtool. The map
+of CPU to queues is automatically deduced from the IRQ affinities
+configured for each receive queue by the driver, so no additional
+configuration should be necessary.
+
+== Suggested Configuration
+
+This technique should be enabled whenever one wants to use RFS and the
+NIC supports hardware acceleration.
+
+XPS: Transmit Packet Steering
+=============================
+
+Transmit Packet Steering is a mechanism for intelligently selecting
+which transmit queue to use when transmitting a packet on a multi-queue
+device. To accomplish this, a mapping from CPU to hardware queue(s) is
+recorded. The goal of this mapping is usually to assign queues
+exclusively to a subset of CPUs, where the transmit completions for
+these queues are processed on a CPU within this set. This choice
+provides two benefits. First, contention on the device queue lock is
+significantly reduced since fewer CPUs contend for the same queue
+(contention can be eliminated completely if each CPU has its own
+transmit queue). Secondly, cache miss rate on transmit completion is
+reduced, in particular for data cache lines that hold the sk_buff
+structures.
+
+XPS is configured per transmit queue by setting a bitmap of CPUs that
+may use that queue to transmit. The reverse mapping, from CPUs to
+transmit queues, is computed and maintained for each network device.
+When transmitting the first packet in a flow, the function
+get_xps_queue() is called to select a queue. This function uses the ID
+of the running CPU as a key into the CPU-to-queue lookup table. If the
+ID matches a single queue, that is used for transmission. If multiple
+queues match, one is selected by using the flow hash to compute an index
+into the set.
+
+The queue chosen for transmitting a particular flow is saved in the
+corresponding socket structure for the flow (e.g. a TCP connection).
+This transmit queue is used for subsequent packets sent on the flow to
+prevent out of order (ooo) packets. The choice also amortizes the cost
+of calling get_xps_queues() over all packets in the flow. To avoid
+ooo packets, the queue for a flow can subsequently only be changed if
+skb->ooo_okay is set for a packet in the flow. This flag indicates that
+there are no outstanding packets in the flow, so the transmit queue can
+change without the risk of generating out of order packets. The
+transport layer is responsible for setting ooo_okay appropriately. TCP,
+for instance, sets the flag when all data for a connection has been
+acknowledged.
+
+==== XPS Configuration
+
+XPS is only available if the kconfig symbol CONFIG_XPS is enabled (on by
+default for SMP). The functionality remains disabled until explicitly
+configured. To enable XPS, the bitmap of CPUs that may use a transmit
+queue is configured using the sysfs file entry:
+
+/sys/class/net/<dev>/queues/tx-<n>/xps_cpus
+
+== Suggested Configuration
+
+For a network device with a single transmission queue, XPS configuration
+has no effect, since there is no choice in this case. In a multi-queue
+system, XPS is preferably configured so that each CPU maps onto one queue.
+If there are as many queues as there are CPUs in the system, then each
+queue can also map onto one CPU, resulting in exclusive pairings that
+experience no contention. If there are fewer queues than CPUs, then the
+best CPUs to share a given queue are probably those that share the cache
+with the CPU that processes transmit completions for that queue
+(transmit interrupts).
+

 defined in include/linux/pm.h, providing a set of power management callbacks
 analogous to the subsystem-level and device driver callbacks that are executed
-for the given device during all power transitions, in addition to the respective
-subsystem-level callbacks.  Specifically, the power domain "suspend" callbacks
-(i.e. ->runtime_suspend(), ->suspend(), ->freeze(), ->poweroff(), etc.) are
-executed after the analogous subsystem-level callbacks, while the power domain
-"resume" callbacks (i.e. ->runtime_resume(), ->resume(), ->thaw(), ->restore,
-etc.) are executed before the analogous subsystem-level callbacks.  Error codes
-returned by the "suspend" and "resume" power domain callbacks are ignored.
-
-Power domain ->runtime_idle() callback is executed before the subsystem-level
-->runtime_idle() callback and the result returned by it is not ignored.  Namely,
-if it returns error code, the subsystem-level ->runtime_idle() callback will not
-be called and the helper function rpm_idle() executing it will return error
-code.  This mechanism is intended to help platforms where saving device state
-is a time consuming operation and should only be carried out if all devices
-in the power domain are idle, before turning off the shared power resource(s).
-Namely, the power domain ->runtime_idle() callback may return error code until
-the pm_runtime_idle() helper (or its asychronous version) has been called for
-all devices in the power domain (it is recommended that the returned error code
-be -EBUSY in those cases), preventing the subsystem-level ->runtime_idle()
-callback from being run prematurely.
-
-The support for device power domains is only relevant to platforms needing to
-use the same subsystem-level (e.g. platform bus type) and device driver power
-management callbacks in many different power domain configurations and wanting
-to avoid incorporating the support for power domains into the subsystem-level
-callbacks.  The other platforms need not implement it or take it into account
-in any way.
-
-
-System Devices
---------------
-System devices (sysdevs) follow a slightly different API, which can be found in
-
-	include/linux/sysdev.h
-	drivers/base/sys.c
-
-System devices will be suspended with interrupts disabled, and after all other
-devices have been suspended.  On resume, they will be resumed before any other
-devices, and also with interrupts disabled.  These things occur in special
-"sysdev_driver" phases, which affect only system devices.
-
-Thus, after the suspend_noirq (or freeze_noirq or poweroff_noirq) phase, when
-the non-boot CPUs are all offline and IRQs are disabled on the remaining online
-CPU, then a sysdev_driver.suspend phase is carried out, and the system enters a
-sleep state (or a system image is created).  During resume (or after the image
-has been created or loaded) a sysdev_driver.resume phase is carried out, IRQs
-are enabled on the only online CPU, the non-boot CPUs are enabled, and the
-resume_noirq (or thaw_noirq or restore_noirq) phase begins.
-
-Code to actually enter and exit the system-wide low power state sometimes
-involves hardware details that are only known to the boot firmware, and
-may leave a CPU running software (from SRAM or flash memory) that monitors
-the system and manages its wakeup sequence.
+for the given device during all power transitions, instead of the respective
+subsystem-level callbacks.  Specifically, if a device's pm_domain pointer is
+not NULL, the ->suspend() callback from the object pointed to by it will be
+executed instead of its subsystem's (e.g. bus type's) ->suspend() callback and
+anlogously for all of the remaining callbacks.  In other words, power management
+domain callbacks, if defined for the given device, always take precedence over
+the callbacks provided by the device's subsystem (e.g. bus type).
+
+The support for device power management domains is only relevant to platforms
+needing to use the same device driver power management callbacks in many
+different power domain configurations and wanting to avoid incorporating the
+support for power domains into subsystem-level callbacks, for example by
+modifying the platform bus type.  Other platforms need not implement it or take
+it into account in any way.

+Ramoops oops/panic logger
+=========================
+
+Sergiu Iordache <sergiu@chromium.org>
+
+Updated: 8 August 2011
+
+0. Introduction
+
+Ramoops is an oops/panic logger that writes its logs to RAM before the system
+crashes. It works by logging oopses and panics in a circular buffer. Ramoops
+needs a system with persistent RAM so that the content of that area can
+survive after a restart.
+
+1. Ramoops concepts
+
+Ramoops uses a predefined memory area to store the dump. The start and size of
+the memory area are set using two variables:
+  * "mem_address" for the start
+  * "mem_size" for the size. The memory size will be rounded down to a
+  power of two.
+
+The memory area is divided into "record_size" chunks (also rounded down to
+power of two) and each oops/panic writes a "record_size" chunk of
+information.
+
+Dumping both oopses and panics can be done by setting 1 in the "dump_oops"
+variable while setting 0 in that variable dumps only the panics.
+
+The module uses a counter to record multiple dumps but the counter gets reset
+on restart (i.e. new dumps after the restart will overwrite old ones).
+
+2. Setting the parameters
+
+Setting the ramoops parameters can be done in 2 different manners:
+ 1. Use the module parameters (which have the names of the variables described
+ as before).
+ 2. Use a platform device and set the platform data. The parameters can then
+ be set through that platform data. An example of doing that is:
+
+#include <linux/ramoops.h>
+[...]
+
+static struct ramoops_platform_data ramoops_data = {
+        .mem_size               = <...>,
+        .mem_address            = <...>,
+        .record_size            = <...>,
+        .dump_oops              = <...>,
+};
+
+static struct platform_device ramoops_dev = {
+        .name = "ramoops",
+        .dev = {
+                .platform_data = &ramoops_data,
+        },
+};
+
+[... inside a function ...]
+int ret;
+
+ret = platform_device_register(&ramoops_dev);
+if (ret) {
+	printk(KERN_ERR "unable to register platform device\n");
+	return ret;
+}
+
+3. Dump format
+
+The data dump begins with a header, currently defined as "====" followed by a
+timestamp and a new line. The dump then continues with the actual data.
+
+4. Reading the data
+
+The dump data can be read from memory (through /dev/mem or other means).
+Getting the module parameters, which are needed in order to parse the data, can
+be done through /sys/module/ramoops/parameters/* .

-Channel attached Tape device driver 
-
------------------------------WARNING-----------------------------------------
-This driver is considered to be EXPERIMENTAL. Do NOT use it in 
-production environments. Feel free to test it and report problems back to us. 
------------------------------------------------------------------------------
-
-The LINUX for zSeries tape device driver manages channel attached tape drives 
-which are compatible to IBM 3480 or IBM 3490 magnetic tape subsystems. This 
-includes various models of these devices (for example the 3490E). 
-
-
-Tape driver features 
-
-The device driver supports a maximum of 128 tape devices. 
-No official LINUX device major number is assigned to the zSeries tape device 
-driver. It allocates major numbers dynamically and reports them on system 
-startup. 
-Typically it will get major number 254 for both the character device front-end 
-and the block device front-end. 
-
-The tape device driver needs no kernel parameters. All supported devices 
-present are detected on driver initialization at system startup or module load.
-The devices detected are ordered by their subchannel numbers. The device with 
-the lowest subchannel number becomes device 0, the next one will be device 1 
-and so on. 
-
-
-Tape character device front-end 
-
-The usual way to read or write to the tape device is through the character 
-device front-end. The zSeries tape device driver provides two character devices
-for each physical device -- the first of these will rewind automatically when 
-it is closed, the second will not rewind automatically. 
-
-The character device nodes are named /dev/rtibm0 (rewinding) and /dev/ntibm0 
-(non-rewinding) for the first device, /dev/rtibm1 and /dev/ntibm1 for the 
-second, and so on. 
-
-The character device front-end can be used as any other LINUX tape device. You 
-can write to it and read from it using LINUX facilities such as GNU tar. The 
-tool mt can be used to perform control operations, such as rewinding the tape 
-or skipping a file. 
-
-Most LINUX tape software should work with either tape character device. 
-
-
-Tape block device front-end 
-
-The tape device may also be accessed as a block device in read-only mode. 
-This could be used for software installation in the same way as it is used with 
-other operation systems on the zSeries platform (and most LINUX 
-distributions are shipped on compact disk using ISO9660 filesystems). 
-
-One block device node is provided for each physical device. These are named 
-/dev/btibm0 for the first device, /dev/btibm1 for the second and so on. 
-You should only use the ISO9660 filesystem on LINUX for zSeries tapes because 
-the physical tape devices cannot perform fast seeks and the ISO9660 system is 
-optimized for this situation. 
-
-
-Tape block device example 
-
-In this example a tape with an ISO9660 filesystem is created using the first 
-tape device. ISO9660 filesystem support must be built into your system kernel
-for this. 
-The mt command is used to issue tape commands and the mkisofs command to 
-create an ISO9660 filesystem: 
-
-- create a LINUX directory (somedir) with the contents of the filesystem 
-     mkdir somedir
-     cp contents somedir 
-
-- insert a tape 
-
-- ensure the tape is at the beginning 
-     mt -f /dev/ntibm0 rewind 
-
-- set the blocksize of the character driver. The blocksize 2048 bytes
-  is commonly used on ISO9660 CD-Roms
-     mt -f /dev/ntibm0 setblk 2048 
-
-- write the filesystem to the character device driver 
-     mkisofs -o /dev/ntibm0 somedir 
-
-- rewind the tape again 
-     mt -f /dev/ntibm0 rewind 
-
-- Now you can mount your new filesystem as a block device: 
-     mount -t iso9660 -o ro,block=2048 /dev/btibm0 /mnt

+		Encrypted keys for the eCryptfs filesystem
+
+ECryptfs is a stacked filesystem which transparently encrypts and decrypts each
+file using a randomly generated File Encryption Key (FEK).
+
+Each FEK is in turn encrypted with a File Encryption Key Encryption Key (FEFEK)
+either in kernel space or in user space with a daemon called 'ecryptfsd'.  In
+the former case the operation is performed directly by the kernel CryptoAPI
+using a key, the FEFEK, derived from a user prompted passphrase;  in the latter
+the FEK is encrypted by 'ecryptfsd' with the help of external libraries in order
+to support other mechanisms like public key cryptography, PKCS#11 and TPM based
+operations.
+
+The data structure defined by eCryptfs to contain information required for the
+FEK decryption is called authentication token and, currently, can be stored in a
+kernel key of the 'user' type, inserted in the user's session specific keyring
+by the userspace utility 'mount.ecryptfs' shipped with the package
+'ecryptfs-utils'.
+
+The 'encrypted' key type has been extended with the introduction of the new
+format 'ecryptfs' in order to be used in conjunction with the eCryptfs
+filesystem.  Encrypted keys of the newly introduced format store an
+authentication token in its payload with a FEFEK randomly generated by the
+kernel and protected by the parent master key.
+
+In order to avoid known-plaintext attacks, the datablob obtained through
+commands 'keyctl print' or 'keyctl pipe' does not contain the overall
+authentication token, which content is well known, but only the FEFEK in
+encrypted form.
+
+The eCryptfs filesystem may really benefit from using encrypted keys in that the
+required key can be securely generated by an Administrator and provided at boot
+time after the unsealing of a 'trusted' key in order to perform the mount in a
+controlled environment.  Another advantage is that the key is not exposed to
+threats of malicious software, because it is available in clear form only at
+kernel level.
+
+Usage:
+   keyctl add encrypted name "new ecryptfs key-type:master-key-name keylen" ring
+   keyctl add encrypted name "load hex_blob" ring
+   keyctl update keyid "update key-type:master-key-name"
+
+name:= '<16 hexadecimal characters>'
+key-type:= 'trusted' | 'user'
+keylen:= 64
+
+
+Example of encrypted key usage with the eCryptfs filesystem:
+
+Create an encrypted key "1000100010001000" of length 64 bytes with format

+This file explains the codec-specific mixer controls.
+
+Realtek codecs
+--------------
+
+* Channel Mode
+  This is an enum control to change the surround-channel setup,
+  appears only when the surround channels are available.
+  It gives the number of channels to be used, "2ch", "4ch", "6ch",
+  and "8ch".  According to the configuration, this also controls the
+  jack-retasking of multi-I/O jacks.
+
+* Auto-Mute Mode
+  This is an enum control to change the auto-mute behavior of the
+  headphone and line-out jacks.  If built-in speakers and headphone
+  and/or line-out jacks are available on a machine, this controls
+  appears.
+  When there are only either headphones or line-out jacks, it gives
+  "Disabled" and "Enabled" state.  When enabled, the speaker is muted
+  automatically when a jack is plugged.
+
+  When both headphone and line-out jacks are present, it gives
+  "Disabled", "Speaker Only" and "Line-Out+Speaker".  When
+  speaker-only is chosen, plugging into a headphone or a line-out jack
+  mutes the speakers, but not line-outs.  When line-out+speaker is
+  selected, plugging to a headphone jack mutes both speakers and
+  line-outs.
+
+
+IDT/Sigmatel codecs
+-------------------
+
+* Analog Loopback
+  This control enables/disables the analog-loopback circuit.  This
+  appears only when "loopback" is set to true in a codec hint
+  (see HD-Audio.txt).  Note that on some codecs the analog-loopback
+  and the normal PCM playback are exclusive, i.e. when this is on, you
+  won't hear any PCM stream.
+
+* Swap Center/LFE
+  Swaps the center and LFE channel order.  Normally, the left
+  corresponds to the center and the right to the LFE.  When this is
+  ON, the left to the LFE and the right to the center.
+
+* Headphone as Line Out
+  When this control is ON, treat the headphone jacks as line-out
+  jacks.  That is, the headphone won't auto-mute the other line-outs,
+  and no HP-amp is set to the pins.
+
+* Mic Jack Mode, Line Jack Mode, etc
+  These enum controls the direction and the bias of the input jack
+  pins.  Depending on the jack type, it can set as "Mic In" and "Line 
+  In", for determining the input bias, or it can be set to "Line Out"
+  when the pin is a multi-I/O jack for surround channels.
+
+
+VIA codecs
+----------
+
+* Smart 5.1
+  An enum control to re-task the multi-I/O jacks for surround outputs.
+  When it's ON, the corresponding input jacks (usually a line-in and a
+  mic-in) are switched as the surround and the CLFE output jacks.
+
+* Independent HP
+  When this enum control is enabled, the headphone output is routed
+  from an individual stream (the third PCM such as hw:0,2) instead of
+  the primary stream.  In the case the headphone DAC is shared with a
+  side or a CLFE-channel DAC, the DAC is switched to the headphone
+  automatically.
+
+* Loopback Mixing
+  An enum control to determine whether the analog-loopback route is
+  enabled or not.  When it's enabled, the analog-loopback is mixed to
+  the front-channel.  Also, the same route is used for the headphone
+  and speaker outputs.  As a side-effect, when this mode is set, the
+  individual volume controls will be no longer available for
+  headphones and speakers because there is only one DAC connected to a
+  mixer widget.
+
+* Dynamic Power-Control
+  This control determines whether the dynamic power-control per jack
+  detection is enabled or not.  When enabled, the widgets power state
+  (D0/D3) are changed dynamically depending on the jack plugging
+  state for saving power consumptions.  However, if your system
+  doesn't provide a proper jack-detection, this won't work; in such a
+  case, turn this control OFF.
+
+* Jack Detect
+  This control is provided only for VT1708 codec which gives no proper
+  unsolicited event per jack plug.  When this is on, the driver polls
+  the jack detection so that the headphone auto-mute can work, while 
+  turning this off would reduce the power consumption.

+
+ Functional partitioning
+ -----------------------
+
+ Consists of the following (in the same order as the list under file
+ partitioning):-
+
+ 1. V4L2 display driver
+    Implements creation of video2 and video3 device nodes and
+    provides v4l2 device interface to manage VID0 and VID1 layers.
+
+ 2. Display controller
+    Loads up VENC, OSD and external encoders such as ths8200. It provides
+    a set of API calls to V4L2 drivers to set the output/standards
+    in the VENC or external sub devices. It also provides
+    a device object to access the services from OSD subdevice
+    using sub device ops. The connection of external encoders to VENC LCD
+    controller port is done at init time based on default output and standard
+    selection or at run time when application change the output through
+    V4L2 IOCTLs.
+
+    When connected to an external encoder, vpbe controller is also responsible
+    for setting up the interface between VENC and external encoders based on
+    board specific settings (specified in board-xxx-evm.c). This allows
+    interfacing external encoders such as ths8200. The setup_if_config()
+    is implemented for this as well as configure_venc() (part of the next patch)
+    API to set timings in VENC for a specific display resolution. As of this
+    patch series, the interconnection and enabling and setting of the external
+    encoders is not present, and would be a part of the next patch series.
+
+ 3. VENC subdevice module
+    Responsible for setting outputs provided through internal DACs and also
+    setting timings at LCD controller port when external encoders are connected
+    at the port or LCD panel timings required. When external encoder/LCD panel
+    is connected, the timings for a specific standard/preset is retrieved from
+    the board specific table and the values are used to set the timings in
+    venc using non-standard timing mode.
+
+    Support LCD Panel displays using the VENC. For example to support a Logic
+    PD display, it requires setting up the LCD controller port with a set of
+    timings for the resolution supported and setting the dot clock. So we could
+    add the available outputs as a board specific entry (i.e add the "LogicPD"
+    output name to board-xxx-evm.c). A table of timings for various LCDs
+    supported can be maintained in the board specific setup file to support
+    various LCD displays.As of this patch a basic driver is present, and this
+    support for external encoders and displays forms a part of the next
+    patch series.
+
+ 4. OSD module
+    OSD module implements all OSD layer management and hardware specific
+    features. The VPBE module interacts with the OSD for enabling and
+    disabling appropriate features of the OSD.
+
+ Current status:-
+
+ A fully functional working version of the V4L2 driver is available. This
+ driver has been tested with NTSC and PAL standards and buffer streaming.
+
+ Following are TBDs.
+
+ vpbe display controller
+    - Add support for external encoders.
+    - add support for selecting external encoder as default at probe time.
+
+ vpbe venc sub device
+    - add timings for supporting ths8200
+    - add support for LogicPD LCD.
+
+ FB drivers
+    - Add support for fbdev drivers.- Ready and part of subsequent patches.

+Handling autogain/gain-type Controls with Auto Clusters
+=======================================================
+
+A common type of control cluster is one that handles 'auto-foo/foo'-type
+controls. Typical examples are autogain/gain, autoexposure/exposure,
+autowhitebalance/red balance/blue balance. In all cases you have one controls
+that determines whether another control is handled automatically by the hardware,
+or whether it is under manual control from the user.
+
+If the cluster is in automatic mode, then the manual controls should be
+marked inactive. When the volatile controls are read the g_volatile_ctrl
+operation should return the value that the hardware's automatic mode set up
+automatically.
+
+If the cluster is put in manual mode, then the manual controls should become
+active again and the is_volatile flag should be ignored (so g_volatile_ctrl is
+no longer called while in manual mode).
+
+Finally the V4L2_CTRL_FLAG_UPDATE should be set for the auto control since
+changing that control affects the control flags of the manual controls.
+
+In order to simplify this a special variation of v4l2_ctrl_cluster was
+introduced:
+
+void v4l2_ctrl_auto_cluster(unsigned ncontrols, struct v4l2_ctrl **controls,
+			u8 manual_val, bool set_volatile);
+
+The first two arguments are identical to v4l2_ctrl_cluster. The third argument
+tells the framework which value switches the cluster into manual mode. The
+last argument will optionally set the is_volatile flag for the non-auto controls.
+
+The first control of the cluster is assumed to be the 'auto' control.
+
+Using this function will ensure that you don't need to handle all the complex
+flag and volatile handling.

 The V4L2 events provide a generic way to pass events to user space.
 The driver must use v4l2_fh to be able to support V4L2 events.
 
-Useful functions:
+Events are defined by a type and an optional ID. The ID may refer to a V4L2
+object such as a control ID. If unused, then the ID is 0.
+
+When the user subscribes to an event the driver will allocate a number of
+kevent structs for that event. So every (type, ID) event tuple will have
+its own set of kevent structs. This guarantees that if a driver is generating
+lots of events of one type in a short time, then that will not overwrite
+events of another type.
+
+But if you get more events of one type than the number of kevents that were
+reserved, then the oldest event will be dropped and the new one added.
+
+Furthermore, the internal struct v4l2_subscribed_event has merge() and
+replace() callbacks which drivers can set. These callbacks are called when
+a new event is raised and there is no more room. The replace() callback
+allows you to replace the payload of the old event with that of the new event,
+merging any relevant data from the old payload into the new payload that
+replaces it. It is called when this event type has only one kevent struct
+allocated. The merge() callback allows you to merge the oldest event payload
+into that of the second-oldest event payload. It is called when there are two
+or more kevent structs allocated.

+4.62 KVM_CREATE_SPAPR_TCE
+
+Capability: KVM_CAP_SPAPR_TCE
+Architectures: powerpc
+Type: vm ioctl
+Parameters: struct kvm_create_spapr_tce (in)
+Returns: file descriptor for manipulating the created TCE table
+
+This creates a virtual TCE (translation control entry) table, which
+is an IOMMU for PAPR-style virtual I/O.  It is used to translate
+logical addresses used in virtual I/O into guest physical addresses,
+and provides a scatter/gather capability for PAPR virtual I/O.
+
+/* for KVM_CAP_SPAPR_TCE */
+struct kvm_create_spapr_tce {
+	__u64 liobn;
+	__u32 window_size;
+};
+
+The liobn field gives the logical IO bus number for which to create a
+TCE table.  The window_size field specifies the size of the DMA window
+which this TCE table will translate - the table will contain one 64
+bit TCE entry for every 4kiB of the DMA window.
+
+When the guest issues an H_PUT_TCE hcall on a liobn for which a TCE
+table has been created using this ioctl(), the kernel will handle it
+in real mode, updating the TCE table.  H_PUT_TCE calls for other
+liobns will cause a vm exit and must be handled by userspace.
+
+The return value is a file descriptor which can be passed to mmap(2)
+to map the created TCE table into userspace.  This lets userspace read
+the entries written by kernel-handled H_PUT_TCE calls, and also lets
+userspace update the TCE table directly which is useful in some
+circumstances.
+
+4.63 KVM_ALLOCATE_RMA
+
+Capability: KVM_CAP_PPC_RMA
+Architectures: powerpc
+Type: vm ioctl
+Parameters: struct kvm_allocate_rma (out)
+Returns: file descriptor for mapping the allocated RMA
+
+This allocates a Real Mode Area (RMA) from the pool allocated at boot
+time by the kernel.  An RMA is a physically-contiguous, aligned region
+of memory used on older POWER processors to provide the memory which
+will be accessed by real-mode (MMU off) accesses in a KVM guest.
+POWER processors support a set of sizes for the RMA that usually
+includes 64MB, 128MB, 256MB and some larger powers of two.
+
+/* for KVM_ALLOCATE_RMA */
+struct kvm_allocate_rma {
+	__u64 rma_size;
+};
+
+The return value is a file descriptor which can be passed to mmap(2)
+to map the allocated RMA into userspace.  The mapped area can then be
+passed to the KVM_SET_USER_MEMORY_REGION ioctl to establish it as the
+RMA for a virtual machine.  The size of the RMA in bytes (which is
+fixed at host kernel boot time) is returned in the rma_size field of
+the argument structure.
+
+The KVM_CAP_PPC_RMA capability is 1 or 2 if the KVM_ALLOCATE_RMA ioctl
+is supported; 2 if the processor requires all virtual machines to have
+an RMA, or 1 if the processor can use an RMA but doesn't require it,
+because it supports the Virtual RMA (VRMA) facility.

+Nested VMX
+==========
+
+Overview
+---------
+
+On Intel processors, KVM uses Intel's VMX (Virtual-Machine eXtensions)
+to easily and efficiently run guest operating systems. Normally, these guests
+*cannot* themselves be hypervisors running their own guests, because in VMX,
+guests cannot use VMX instructions.
+
+The "Nested VMX" feature adds this missing capability - of running guest
+hypervisors (which use VMX) with their own nested guests. It does so by
+allowing a guest to use VMX instructions, and correctly and efficiently
+emulating them using the single level of VMX available in the hardware.
+
+We describe in much greater detail the theory behind the nested VMX feature,
+its implementation and its performance characteristics, in the OSDI 2010 paper
+"The Turtles Project: Design and Implementation of Nested Virtualization",
+available at:
+
+	http://www.usenix.org/events/osdi10/tech/full_papers/Ben-Yehuda.pdf
+
+
+Terminology
+-----------
+
+Single-level virtualization has two levels - the host (KVM) and the guests.
+In nested virtualization, we have three levels: The host (KVM), which we call
+L0, the guest hypervisor, which we call L1, and its nested guest, which we
+call L2.
+
+
+Known limitations
+-----------------
+
+The current code supports running Linux guests under KVM guests.
+Only 64-bit guest hypervisors are supported.
+
+Additional patches for running Windows under guest KVM, and Linux under
+guest VMware server, and support for nested EPT, are currently running in
+the lab, and will be sent as follow-on patchsets.
+
+
+Running nested VMX
+------------------
+
+The nested VMX feature is disabled by default. It can be enabled by giving
+the "nested=1" option to the kvm-intel module.
+
+No modifications are required to user space (qemu). However, qemu's default
+emulated CPU type (qemu64) does not list the "VMX" CPU feature, so it must be
+explicitly enabled, by giving qemu one of the following options:
+
+     -cpu host              (emulated CPU has all features of the real CPU)
+
+     -cpu qemu64,+vmx       (add just the vmx feature to a named CPU type)
+
+
+ABIs
+----
+
+Nested VMX aims to present a standard and (eventually) fully-functional VMX
+implementation for the a guest hypervisor to use. As such, the official
+specification of the ABI that it provides is Intel's VMX specification,
+namely volume 3B of their "Intel 64 and IA-32 Architectures Software
+Developer's Manual". Not all of VMX's features are currently fully supported,
+but the goal is to eventually support them all, starting with the VMX features
+which are used in practice by popular hypervisors (KVM and others).
+
+As a VMX implementation, nested VMX presents a VMCS structure to L1.
+As mandated by the spec, other than the two fields revision_id and abort,
+this structure is *opaque* to its user, who is not supposed to know or care
+about its internal structure. Rather, the structure is accessed through the
+VMREAD and VMWRITE instructions.
+Still, for debugging purposes, KVM developers might be interested to know the
+internals of this structure; This is struct vmcs12 from arch/x86/kvm/vmx.c.
+
+The name "vmcs12" refers to the VMCS that L1 builds for L2. In the code we
+also have "vmcs01", the VMCS that L0 built for L1, and "vmcs02" is the VMCS
+which L0 builds to actually run L2 - how this is done is explained in the
+aforementioned paper.
+
+For convenience, we repeat the content of struct vmcs12 here. If the internals
+of this structure changes, this can break live migration across KVM versions.
+VMCS12_REVISION (from vmx.c) should be changed if struct vmcs12 or its inner
+struct shadow_vmcs is ever changed.

+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
+  Device
+
+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.

+  VIRTIO_NET_F_MAC (5) Device has given MAC address.
+
+  VIRTIO_NET_F_GSO (6) (Deprecated) device handles packets with
+    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_GUEST_UFO (10) Guest can receive UFO.
+
+  VIRTIO_NET_F_HOST_TSO4 (11) Device can receive TSOv4.
+
+  VIRTIO_NET_F_HOST_TSO6 (12) Device can receive TSOv6.
+
+  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;
+

+
+	u8 gso_type;
+
+	u16 hdr_len;

+

+
+};
+
+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_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:

+    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 */

+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.

+    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

+The Linux WatchDog Timer Driver Core kernel API.
+===============================================
+Last reviewed: 22-Jul-2011
+
+Wim Van Sebroeck <wim@iguana.be>
+
+Introduction
+------------
+This document does not describe what a WatchDog Timer (WDT) Driver or Device is.
+It also does not describe the API which can be used by user space to communicate
+with a WatchDog Timer. If you want to know this then please read the following
+file: Documentation/watchdog/watchdog-api.txt .
+
+So what does this document describe? It describes the API that can be used by
+WatchDog Timer Drivers that want to use the WatchDog Timer Driver Core
+Framework. This framework provides all interfacing towards user space so that
+the same code does not have to be reproduced each time. This also means that
+a watchdog timer driver then only needs to provide the different routines
+(operations) that control the watchdog timer (WDT).
+
+The API
+-------
+Each watchdog timer driver that wants to use the WatchDog Timer Driver Core
+must #include <linux/watchdog.h> (you would have to do this anyway when
+writing a watchdog device driver). This include file contains following
+register/unregister routines:
+
+extern int watchdog_register_device(struct watchdog_device *);
+extern void watchdog_unregister_device(struct watchdog_device *);
+
+The watchdog_register_device routine registers a watchdog timer device.
+The parameter of this routine is a pointer to a watchdog_device structure.
+This routine returns zero on success and a negative errno code for failure.
+
+The watchdog_unregister_device routine deregisters a registered watchdog timer
+device. The parameter of this routine is the pointer to the registered
+watchdog_device structure.
+
+The watchdog device structure looks like this:
+
+struct watchdog_device {
+	const struct watchdog_info *info;
+	const struct watchdog_ops *ops;
+	unsigned int bootstatus;
+	unsigned int timeout;
+	unsigned int min_timeout;
+	unsigned int max_timeout;
+	void *driver_data;
+	unsigned long status;
+};
+
+It contains following fields:
+* info: a pointer to a watchdog_info structure. This structure gives some
+  additional information about the watchdog timer itself. (Like it's unique name)
+* ops: a pointer to the list of watchdog operations that the watchdog supports.
+* timeout: the watchdog timer's timeout value (in seconds).
+* min_timeout: the watchdog timer's minimum timeout value (in seconds).
+* max_timeout: the watchdog timer's maximum timeout value (in seconds).
+* bootstatus: status of the device after booting (reported with watchdog
+  WDIOF_* status bits).
+* driver_data: a pointer to the drivers private data of a watchdog device.
+  This data should only be accessed via the watchdog_set_drvadata and
+  watchdog_get_drvdata routines.
+* status: this field contains a number of status bits that give extra
+  information about the status of the device (Like: is the watchdog timer
+  running/active, is the nowayout bit set, is the device opened via
+  the /dev/watchdog interface or not, ...).
+
+The list of watchdog operations is defined as:
+
+struct watchdog_ops {
+	struct module *owner;
+	/* mandatory operations */
+	int (*start)(struct watchdog_device *);
+	int (*stop)(struct watchdog_device *);
+	/* optional operations */
+	int (*ping)(struct watchdog_device *);
+	unsigned int (*status)(struct watchdog_device *);
+	int (*set_timeout)(struct watchdog_device *, unsigned int);
+	long (*ioctl)(struct watchdog_device *, unsigned int, unsigned long);
+};
+
+It is important that you first define the module owner of the watchdog timer
+driver's operations. This module owner will be used to lock the module when
+the watchdog is active. (This to avoid a system crash when you unload the
+module and /dev/watchdog is still open).
+Some operations are mandatory and some are optional. The mandatory operations
+are:
+* start: this is a pointer to the routine that starts the watchdog timer
+  device.
+  The routine needs a pointer to the watchdog timer device structure as a
+  parameter. It returns zero on success or a negative errno code for failure.
+* stop: with this routine the watchdog timer device is being stopped.
+  The routine needs a pointer to the watchdog timer device structure as a
+  parameter. It returns zero on success or a negative errno code for failure.
+  Some watchdog timer hardware can only be started and not be stopped. The
+  driver supporting this hardware needs to make sure that a start and stop
+  routine is being provided. This can be done by using a timer in the driver
+  that regularly sends a keepalive ping to the watchdog timer hardware.
+
+Not all watchdog timer hardware supports the same functionality. That's why
+all other routines/operations are optional. They only need to be provided if
+they are supported. These optional routines/operations are:
+* ping: this is the routine that sends a keepalive ping to the watchdog timer
+  hardware.
+  The routine needs a pointer to the watchdog timer device structure as a
+  parameter. It returns zero on success or a negative errno code for failure.
+  Most hardware that does not support this as a separate function uses the
+  start function to restart the watchdog timer hardware. And that's also what
+  the watchdog timer driver core does: to send a keepalive ping to the watchdog
+  timer hardware it will either use the ping operation (when available) or the
+  start operation (when the ping operation is not available).
+  (Note: the WDIOC_KEEPALIVE ioctl call will only be active when the
+  WDIOF_KEEPALIVEPING bit has been set in the option field on the watchdog's
+  info structure).
+* status: this routine checks the status of the watchdog timer device. The
+  status of the device is reported with watchdog WDIOF_* status flags/bits.
+* set_timeout: this routine checks and changes the timeout of the watchdog
+  timer device. It returns 0 on success, -EINVAL for "parameter out of range"
+  and -EIO for "could not write value to the watchdog". On success the timeout
+  value of the watchdog_device will be changed to the value that was just used
+  to re-program the watchdog timer device.
+  (Note: the WDIOF_SETTIMEOUT needs to be set in the options field of the
+  watchdog's info structure).
+* ioctl: if this routine is present then it will be called first before we do
+  our own internal ioctl call handling. This routine should return -ENOIOCTLCMD
+  if a command is not supported. The parameters that are passed to the ioctl
+  call are: watchdog_device, cmd and arg.
+
+The status bits should (preferably) be set with the set_bit and clear_bit alike
+bit-operations. The status bits that are defined are:
+* WDOG_ACTIVE: this status bit indicates whether or not a watchdog timer device
+  is active or not. When the watchdog is active after booting, then you should
+  set this status bit (Note: when you register the watchdog timer device with
+  this bit set, then opening /dev/watchdog will skip the start operation)
+* WDOG_DEV_OPEN: this status bit shows whether or not the watchdog device
+  was opened via /dev/watchdog.
+  (This bit should only be used by the WatchDog Timer Driver Core).
+* WDOG_ALLOW_RELEASE: this bit stores whether or not the magic close character
+  has been sent (so that we can support the magic close feature).
+  (This bit should only be used by the WatchDog Timer Driver Core).
+* WDOG_NO_WAY_OUT: this bit stores the nowayout setting for the watchdog.
+  If this bit is set then the watchdog timer will not be able to stop.
+
+Note: The WatchDog Timer Driver Core supports the magic close feature and
+the nowayout feature. To use the magic close feature you must set the
+WDIOF_MAGICCLOSE bit in the options field of the watchdog's info structure.
+The nowayout feature will overrule the magic close feature.
+
+To get or set driver specific data the following two helper functions should be
+used:
+
+static inline void watchdog_set_drvdata(struct watchdog_device *wdd, void *data)
+static inline void *watchdog_get_drvdata(struct watchdog_device *wdd)
+
+The watchdog_set_drvdata function allows you to add driver specific data. The
+arguments of this function are the watchdog device where you want to add the
+driver specific data to and a pointer to the data itself.
+
+The watchdog_get_drvdata function allows you to retrieve driver specific data.
+The argument of this function is the watchdog device where you want to retrieve
+data from. The function retruns the pointer to the driver specific data.

+This file documents some of the kernel entries in
+arch/x86/kernel/entry_64.S.  A lot of this explanation is adapted from
+an email from Ingo Molnar:
+
+http://lkml.kernel.org/r/<20110529191055.GC9835%40elte.hu>
+
+The x86 architecture has quite a few different ways to jump into
+kernel code.  Most of these entry points are registered in
+arch/x86/kernel/traps.c and implemented in arch/x86/kernel/entry_64.S
+and arch/x86/ia32/ia32entry.S.
+
+The IDT vector assignments are listed in arch/x86/include/irq_vectors.h.
+
+Some of these entries are:
+
+ - system_call: syscall instruction from 64-bit code.
+
+ - ia32_syscall: int 0x80 from 32-bit or 64-bit code; compat syscall
+   either way.
+
+ - ia32_syscall, ia32_sysenter: syscall and sysenter from 32-bit
+   code
+
+ - interrupt: An array of entries.  Every IDT vector that doesn't
+   explicitly point somewhere else gets set to the corresponding
+   value in interrupts.  These point to a whole array of
+   magically-generated functions that make their way to do_IRQ with
+   the interrupt number as a parameter.
+
+ - emulate_vsyscall: int 0xcc, a special non-ABI entry used by
+   vsyscall emulation.
+
+ - APIC interrupts: Various special-purpose interrupts for things
+   like TLB shootdown.
+
+ - Architecturally-defined exceptions like divide_error.
+
+There are a few complexities here.  The different x86-64 entries
+have different calling conventions.  The syscall and sysenter
+instructions have their own peculiar calling conventions.  Some of
+the IDT entries push an error code onto the stack; others don't.
+IDT entries using the IST alternative stack mechanism need their own
+magic to get the stack frames right.  (You can find some
+documentation in the AMD APM, Volume 2, Chapter 8 and the Intel SDM,
+Volume 3, Chapter 6.)
+
+Dealing with the swapgs instruction is especially tricky.  Swapgs
+toggles whether gs is the kernel gs or the user gs.  The swapgs
+instruction is rather fragile: it must nest perfectly and only in
+single depth, it should only be used if entering from user mode to
+kernel mode and then when returning to user-space, and precisely
+so. If we mess that up even slightly, we crash.
+
+So when we have a secondary entry, already in kernel mode, we *must
+not* use SWAPGS blindly - nor must we forget doing a SWAPGS when it's
+not switched/swapped yet.
+
+Now, there's a secondary complication: there's a cheap way to test
+which mode the CPU is in and an expensive way.
+
+The cheap way is to pick this info off the entry frame on the kernel
+stack, from the CS of the ptregs area of the kernel stack:
+
+	xorl %ebx,%ebx
+	testl $3,CS+8(%rsp)
+	je error_kernelspace
+	SWAPGS
+
+The expensive (paranoid) way is to read back the MSR_GS_BASE value
+(which is what SWAPGS modifies):
+
+	movl $1,%ebx
+	movl $MSR_GS_BASE,%ecx
+	rdmsr
+	testl %edx,%edx
+	js 1f   /* negative -> in kernel */
+	SWAPGS
+	xorl %ebx,%ebx
+1:	ret
+
+and the whole paranoid non-paranoid macro complexity is about whether
+to suffer that RDMSR cost.
+
+If we are at an interrupt or user-trap/gate-alike boundary then we can
+use the faster check: the stack will be a reliable indicator of
+whether SWAPGS was already done: if we see that we are a secondary
+entry interrupting kernel mode execution, then we know that the GS
+base has already been switched. If it says that we interrupted
+user-space execution then we must do the SWAPGS.
+
+But if we are in an NMI/MCE/DEBUG/whatever super-atomic entry context,
+which might have triggered right after a normal entry wrote CS to the
+stack but before we executed SWAPGS, then the only safe way to check
+for GS is the slower method: the RDMSR.
+
+So we try only to mark those entry methods 'paranoid' that absolutely
+need the more expensive check for the GS base - and we generate all
+'normal' entry points with the regular (faster) entry macros.

+你可以安全地通过GPG标记附件，但是内嵌补丁最好不要使用GPG标记它们。作为内嵌文本的签发补丁，
+当从GPG中提取7位编码时会使他们变的更加复杂。

+当你要保存将要发送的内嵌文本补丁，你可以从消息列表窗格选择包含补丁的邮件，然后右击选择
+"save as"。你可以使用一个没有更改的包含补丁的邮件，如果它是以正确的形式组成。当你正真在它
+自己的窗口之下察看，那时没有选项可以保存邮件--已经有一个这样的bug被汇报到了kmail的bugzilla
+并且希望这将会被处理。邮件是以只针对某个用户可读写的权限被保存的，所以如果你想把邮件复制到其他地方，
+你不得不把他们的权限改为组或者整体可读。

+Mutt不自带编辑器，所以不管你使用什么编辑器都不应该带有自动断行。大多数编辑器都带有
+一个"insert file"选项，它可以通过不改变文件内容的方式插入文件。
 
-'vim'浣?涓?mutt???缂?杈????锛?
+'vim'作为mutt的编辑器：

+- 内嵌文本可以很好的工作（或者使用附件）。
+- 允许使用外部的编辑器。
+- 对于目录较多时非常慢。
+- 如果通过non-SSL连接，无法使用TLS SMTP授权。
+- 在组成窗口中有一个很有用的ruler bar。

+- 你需要使Thunderbird变为预先格式方式：
+  如果默认情况下你书写的是HTML格式，那不是很难。仅仅从标题栏的下拉框中选择"Preformat"格式。
+  如果默认情况下你书写的是文本格式，你不得把它改为HTML格式（仅仅作为一次性的）来书写新的消息，
+  然后强制使它回到文本格式，否则它就会拆行。要实现它，在写信的图标上使用shift键来使它变为HTML
+  格式，然后标题栏的下拉框中选择"Preformat"格式。

+- 允许使用外部的编辑器：
+  针对Thunderbird打补丁最简单的方法就是使用一个"external editor"扩展，然后使用你最喜欢的
+  $EDITOR来读取或者合并补丁到文本中。要实现它，可以下载并且安装这个扩展，然后添加一个使用它的
+  按键View->Toolbars->Customize...最后当你书写信息的时候仅仅点击它就可以了。
