firmware assigned instance number of the PCI
device that can help in understanding the firmware
intended order of the PCI device.

+What: /sys/bus/pci/devices/.../d3cold_allowed
+Date: July 2012
+Contact: Huang Ying <ying.huang@intel.com>
+Description:
+ d3cold_allowed is bit to control whether the corresponding PCI
+ device can be put into D3Cold state. If it is cleared, the
+ device will never be put into D3Cold state. If it is set, the
+ device may be put into D3Cold state if other requirements are
+ satisfied too. Reading this attribute will show the current
+ value of d3cold_allowed bit. Writing this attribute will set
+ the value of d3cold_allowed bit.

+ <para>This is a multi-planar format, as opposed to a packed format.
+The three components are separated into three sub-images or planes.
+
+The Y plane is first. The Y plane has one byte per pixel. The Cr data
+constitutes the second plane which is half the width and half
+the height of the Y plane (and of the image). Each Cr belongs to four
+pixels, a two-by-two square of the image. For example,
+Cr<subscript>0</subscript> belongs to Y'<subscript>00</subscript>,
+Y'<subscript>01</subscript>, Y'<subscript>10</subscript>, and
+Y'<subscript>11</subscript>. The Cb data, just like the Cr plane, constitutes
+the third plane. </para>
+
+ <para>If the Y plane has pad bytes after each row, then the Cr
+and Cb planes have half as many pad bytes after their rows. In other
+words, two Cx rows (including padding) is exactly as long as one Y row
+(including padding).</para>

<title>Configuration</title>
API lacks any support for composing to and cropping from an image inside a
memory buffer. The application could configure a capture device to fill only a
part of an image by abusing V4L2 API. Cropping a smaller image from a larger
-one is achieved by setting the field <structfield>
-&v4l2-pix-format;::bytesperline </structfield>. Introducing an image offsets
-could be done by modifying field <structfield> &v4l2-buffer;::m:userptr
-</structfield> before calling <constant> VIDIOC_QBUF </constant>. Those
+one is achieved by setting the field
+&v4l2-pix-format;<structfield>::bytesperline</structfield>. Introducing an image offsets
+could be done by modifying field &v4l2-buffer;<structfield>::m_userptr</structfield>
+before calling <constant> VIDIOC_QBUF </constant>. Those
operations should be avoided because they are not portable (endianness), and do
not work for macroblock and Bayer formats and mmap buffers. The selection API
deals with configuration of buffer cropping/composing in a clear, intuitive and
portable way. Next, with the selection API the concepts of the padded target
-and constraints flags are introduced. Finally, <structname> &v4l2-crop;
-</structname> and <structname> &v4l2-cropcap; </structname> have no reserved
-fields. Therefore there is no way to extend their functionality. The new
-<structname> &v4l2-selection; </structname> provides a lot of place for future
+and constraints flags are introduced. Finally, &v4l2-crop; and &v4l2-cropcap;
+have no reserved fields. Therefore there is no way to extend their functionality.
+The new &v4l2-selection; provides a lot of place for future
extensions. Driver developers are encouraged to implement only selection API.
The former cropping API would be simulated using the new one. </para>

+CFQ (Complete Fairness Queueing)
+===============================
+
+The main aim of CFQ scheduler is to provide a fair allocation of the disk
+I/O bandwidth for all the processes which requests an I/O operation.
+
+CFQ maintains the per process queue for the processes which request I/O
+operation(syncronous requests). In case of asynchronous requests, all the
+requests from all the processes are batched together according to their
+process's I/O priority.
+
CFQ ioscheduler tunables
========================
controller or for storage arrays), setting slice_idle=0 might end up in better
throughput and acceptable latencies.
+back_seek_max
+-------------
+This specifies, given in Kbytes, the maximum "distance" for backward seeking.
+The distance is the amount of space from the current head location to the
+sectors that are backward in terms of distance.
+
+This parameter allows the scheduler to anticipate requests in the "backward"
+direction and consider them as being the "next" if they are within this
+distance from the current head location.
+
+back_seek_penalty
+-----------------
+This parameter is used to compute the cost of backward seeking. If the
+backward distance of request is just 1/back_seek_penalty from a "front"
+request, then the seeking cost of two requests is considered equivalent.
+
+So scheduler will not bias toward one or the other request (otherwise scheduler
+will bias toward front request). Default value of back_seek_penalty is 2.
+
+fifo_expire_async
+-----------------
+This parameter is used to set the timeout of asynchronous requests. Default
+value of this is 248ms.
+
+fifo_expire_sync
+----------------
+This parameter is used to set the timeout of synchronous requests. Default
+value of this is 124ms. In case to favor synchronous requests over asynchronous
+one, this value should be decreased relative to fifo_expire_async.
+
+slice_async
+-----------
+This parameter is same as of slice_sync but for asynchronous queue. The
+default value is 40ms.
+
+slice_async_rq
+--------------
+This parameter is used to limit the dispatching of asynchronous request to
+device request queue in queue's slice time. The maximum number of request that
+are allowed to be dispatched also depends upon the io priority. Default value
+for this is 2.
+
+slice_sync
+----------
+When a queue is selected for execution, the queues IO requests are only
+executed for a certain amount of time(time_slice) before switching to another
+queue. This parameter is used to calculate the time slice of synchronous
+queue.
+
+time_slice is computed using the below equation:-
+time_slice = slice_sync + (slice_sync/5 * (4 - prio)). To increase the
+time_slice of synchronous queue, increase the value of slice_sync. Default
+value is 100ms.
+
+quantum
+-------
+This specifies the number of request dispatched to the device queue. In a
+queue's time slice, a request will not be dispatched if the number of request
+in the device exceeds this parameter. This parameter is used for synchronous
+request.
+
+In case of storage with several disk, this setting can limit the parallel
+processing of request. Therefore, increasing the value can imporve the
+performace although this can cause the latency of some I/O to increase due
+to more number of requests.
+
CFQ IOPS Mode for group scheduling
===================================
Basic CFQ design is to provide priority based time slices. Higher priority
Files denoted with a RO postfix are readonly and the RW postfix means
read-write.
+add_random (RW)
+----------------
+This file allows to trun off the disk entropy contribution. Default
+value of this file is '1'(on).
+
+discard_granularity (RO)
+-----------------------
+This shows the size of internal allocation of the device in bytes, if
+reported by the device. A value of '0' means device does not support
+the discard functionality.
+
+discard_max_bytes (RO)
+----------------------
+Devices that support discard functionality may have internal limits on
+the number of bytes that can be trimmed or unmapped in a single operation.
+The discard_max_bytes parameter is set by the device driver to the maximum
+number of bytes that can be discarded in a single operation. Discard
+requests issued to the device must not exceed this limit. A discard_max_bytes
+value of 0 means that the device does not support discard functionality.
+
+discard_zeroes_data (RO)
+------------------------
+When read, this file will show if the discarded block are zeroed by the
+device or not. If its value is '1' the blocks are zeroed otherwise not.
+
hw_sector_size (RO)
-------------------
This is the hardware sector size of the device, in bytes.
+iostats (RW)
+-------------
+This file is used to control (on/off) the iostats accounting of the
+disk.
+
+logical_block_size (RO)
+-----------------------
+This is the logcal block size of the device, in bytes.
+
max_hw_sectors_kb (RO)
----------------------
This is the maximum number of kilobytes supported in a single data transfer.
+max_integrity_segments (RO)
+---------------------------
+When read, this file shows the max limit of integrity segments as
+set by block layer which a hardware controller can handle.
+
max_sectors_kb (RW)
-------------------
This is the maximum number of kilobytes that the block layer will allow
for a filesystem request. Must be smaller than or equal to the maximum
size allowed by the hardware.
+max_segments (RO)
+-----------------
+Maximum number of segments of the device.
+
+max_segment_size (RO)
+---------------------
+Maximum segment size of the device.
+
+minimum_io_size (RO)
+--------------------
+This is the smallest preferred io size reported by the device.
+
nomerges (RW)
-------------
This enables the user to disable the lookup logic involved with IO
each request queue may have upto N request pools, each independently
regulated by nr_requests.
+optimal_io_size (RO)
+--------------------
+This is the optimal io size reported by the device.
+
+physical_block_size (RO)
+------------------------
+This is the physical block size of device, in bytes.
+
read_ahead_kb (RW)
------------------
Maximum number of kilobytes to read-ahead for filesystems on this block
device.
+rotational (RW)
+---------------
+This file is used to stat if the device is of rotational type or
+non-rotational type.
+
rq_affinity (RW)
----------------
If this option is '1', the block layer will migrate request completions to the

4. User space interfaces
========================
============
This file documents the Texas Instruments OMAP 3 Image Signal Processor (ISP)
-driver located under drivers/media/video/omap3isp. The original driver was
+driver located under drivers/media/platform/omap3isp. The original driver was
written by Texas Instruments but since that it has been rewritten (twice) at
Nokia.
const struct v4l2_ctrl_ops *ops,
u32 id, s32 max, s32 def, const s64 *qmenu_int);
+Standard menu controls with a driver specific menu are added by calling
+v4l2_ctrl_new_std_menu_items:
+
+ struct v4l2_ctrl *v4l2_ctrl_new_std_menu_items(
+ struct v4l2_ctrl_handler *hdl,
+ const struct v4l2_ctrl_ops *ops, u32 id, s32 max,
+ s32 skip_mask, s32 def, const char * const *qmenu);
+
These functions are typically called right after the v4l2_ctrl_handler_init:
static const s64 exp_bias_qmenu[] = {
-2, -1, 0, 1, 2
};
+ static const char * const test_pattern[] = {
+ "Disabled",
+ "Vertical Bars",
+ "Solid Black",
+ "Solid White",
+ };
v4l2_ctrl_handler_init(&foo->ctrl_handler, nr_of_controls);
v4l2_ctrl_new_std(&foo->ctrl_handler, &foo_ctrl_ops,
ARRAY_SIZE(exp_bias_qmenu) - 1,
ARRAY_SIZE(exp_bias_qmenu) / 2 - 1,
exp_bias_qmenu);
+ v4l2_ctrl_new_std_menu_items(&foo->ctrl_handler, &foo_ctrl_ops,
+ V4L2_CID_TEST_PATTERN, ARRAY_SIZE(test_pattern) - 1, 0,
+ 0, test_pattern);
...
if (foo->ctrl_handler.error) {
int err = foo->ctrl_handler.error;
as the last argument an array of signed 64-bit integers that form an exact
menu item list.
+The v4l2_ctrl_new_std_menu_items function is very similar to
+v4l2_ctrl_new_std_menu but takes an extra parameter qmenu, which is the driver
+specific menu for an otherwise standard menu control. A good example for this
+control is the test pattern control for capture/display/sensors devices that
+have the capability to generate test patterns. These test patterns are hardware
+specific, so the contents of the menu will vary from device to device.
+
Note that if something fails, the function will return NULL or an error and
set ctrl_handler->error to the error code. If ctrl_handler->error was already
set, then it will just return and do nothing. This is also true for
v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_MUTE, ...);
v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_BRIGHTNESS, ...);
v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_CONTRAST, ...);
- v4l2_ctrl_add_handler(&video_ctrl_handler, &radio_ctrl_handler);
+ v4l2_ctrl_add_handler(&video_ctrl_handler, &radio_ctrl_handler, NULL);
+
+The last argument to v4l2_ctrl_add_handler() is a filter function that allows
+you to filter which controls will be added. Set it to NULL if you want to add
+all controls.
Or you can add specific controls to a handler:
- name: set to something descriptive and unique.
+- vfl_dir: set this to VFL_DIR_RX for capture devices (VFL_DIR_RX has value 0,
+ so this is normally already the default), set to VFL_DIR_TX for output
+ devices and VFL_DIR_M2M for mem2mem (codec) devices.
+
- fops: set to the v4l2_file_operations struct.
- ioctl_ops: if you use the v4l2_ioctl_ops to simplify ioctl maintenance
(highly recommended to use this and it might become compulsory in the
- future!), then set this to your v4l2_ioctl_ops struct.
+ future!), then set this to your v4l2_ioctl_ops struct. The vfl_type and
+ vfl_dir fields are used to disable ops that do not match the type/dir
+ combination. E.g. VBI ops are disabled for non-VBI nodes, and output ops
+ are disabled for a capture device. This makes it possible to provide
+ just one v4l2_ioctl_ops struct for both vbi and video nodes.
- lock: leave to NULL if you want to do all the locking in the driver.
Otherwise you give it a pointer to a struct mutex_lock and before the
available event type is 'class base + 1'.
An example on how the V4L2 events may be used can be found in the OMAP
-3 ISP driver (drivers/media/video/omap3isp).
+3 ISP driver (drivers/media/platform/omap3isp).
Developers who are interested in more information can go into the relevant
header files; there are a few low-level functions declared there which have
not been talked about here. Also worthwhile is the vivi driver
-(drivers/media/video/vivi.c), which is maintained as an example of how V4L2

- * continue to update the pfn, and as a result memory corruption occours
- * in the new kernel.
- *
- * One way to work around this issue is to allocate a page in the
- * xen-platform pci device's BAR memory range. But pci init is done very
- * late and the shared_info page is already in use very early to read
- * the pvclock. So moving the pfn from RAM to MMIO is racy because some

- * window when the old pfn is moved to the new pfn. There is even a
- * small window were the old pfn is not backed by a mfn, and during that
- * time all reads return -1.
- *
- * Because it is not known upfront where the MMIO region is located it
- * can not be used right from the start in xen_hvm_init_shared_info.
- *
- * To minimise trouble the move of the pfn is done shortly before kexec.
- * This does not eliminate the race because all vcpus are still online

- This is an integrated audio/video driver for EasyCAP cards with
- USB ID 05e1:0408. It supports two hardware variants:
-
- * EasyCAP USB 2.0 Video Adapter with Audio, Model DC60,
- having input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
-
- * EasyCAP002 4-Channel USB 2.0 DVR, having input cables labelled
- 1, 2, 3, 4 and an unlabelled input cable for a microphone.
-
- To compile this driver as a module, choose M here: the
- module will be called easycap
-

-
-SUPPORTED HARDWARE
-------------------
-
-This driver is intended for use with hardware having USB ID 05e1:0408.
-Two kinds of EasyCAP have this USB ID, namely:
-
- * EasyCAP USB 2.0 Video Adapter with Audio, Model DC60,
- having input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
-
- * EasyCAP002 4-Channel USB 2.0 DVR, having input cables labelled
- 1, 2, 3, 4 and an unlabelled input cable for a microphone.
-
-
-BUILD OPTIONS AND DEPENDENCIES
-------------------------------
-
-Unless EASYCAP_DEBUG is defined during compilation it will not be possible
-to select a debug level at the time of module installation.
-
-
-KNOWN RUNTIME ISSUES
---------------------
-
-(1) Intentionally, this driver will not stream material which is unambiguously
-identified by the hardware as copy-protected. Normal video output will be
-present for about a minute but will then freeze when this situation arises.
-
-(2) The controls for luminance, contrast, saturation, hue and volume may not
-always work properly.
-
-(3) Reduced-resolution S-Video seems to suffer from moire artefacts.
-
-
-INPUT NUMBERING
----------------
-
-For the EasyCAP with S-VIDEO input cable the driver regards a request for
-inputs numbered 0 or 1 as referring to CVBS and a request for input
-numbered 5 as referring to S-VIDEO.
-
-For the EasyCAP with four CVBS inputs the driver expects to be asked for
-any one of inputs numbered 1,2,3,4. If input 0 is asked for, it is
-interpreted as input 1.
-
-
-MODULE PARAMETERS
------------------
-
-Three module parameters are defined:
-
-debug the easycap module is configured at diagnostic level n (0 to 9)
-gain audio gain level n (0 to 31, default is 16)
-bars whether to display testcard bars when incoming video signal is lost
- 0 => no, 1 => yes (default)
-
-
-SUPPORTED TV STANDARDS AND RESOLUTIONS
---------------------------------------
-
-The following TV standards are natively supported by the hardware and are
-usable as (for example) the "norm=" parameter in the mplayer command:
-
- PAL_BGHIN, NTSC_N_443,
- PAL_Nc, NTSC_N,
- SECAM, NTSC_M, NTSC_M_JP,
- PAL_60, NTSC_443,
- PAL_M.
-
-In addition, the driver offers "custom" pseudo-standards with a framerate
-which is 20% of the usual framerate. These pseudo-standards are named:
-
- PAL_BGHIN_SLOW, NTSC_N_443_SLOW,
- PAL_Nc_SLOW, NTSC_N_SLOW,
- SECAM_SLOW, NTSC_M_SLOW, NTSC_M_JP_SLOW,
- PAL_60_SLOW, NTSC_443_SLOW,
- PAL_M_SLOW.
-
-
-The available picture sizes are:
-
- at 25 frames per second: 720x576, 704x576, 640x480, 360x288, 320x240;
- at 30 frames per second: 720x480, 640x480, 360x240, 320x240.
-
-
-WHAT'S TESTED AND WHAT'S NOT
-----------------------------
-
-This driver is known to work with mplayer, mencoder, tvtime, zoneminder,
-xawtv, gstreamer and sufficiently recent versions of vlc. An interface
-to ffmpeg is implemented, but serious audio-video synchronization problems
-remain.
-
-The driver is designed to support all the TV standards accepted by the
-hardware, but as yet it has actually been tested on only a few of these.
-
-I have been unable to test and calibrate the S-video input myself because I
-do not possess any equipment with S-video output.
-
-
-UDEV RULES
-----------
-
-In order that the special files /dev/easycap0 and /dev/easysnd1 are created
-with conveniently relaxed permissions when the EasyCAP is plugged in, a file
-is preferably to be provided in directory /etc/udev/rules.d with content:
-
-ACTION!="add|change", GOTO="easycap_rules_end"
-ATTRS{idVendor}=="05e1", ATTRS{idProduct}=="0408", \
- MODE="0666", OWNER="root", GROUP="root"
-LABEL="easycap_rules_end"
-
-
-MODPROBE CONFIGURATION
-----------------------
-
-The easycap module is in competition with the module snd-usb-audio for the
-EasyCAP's audio channel, and its installation can be aided by providing a
-file in directory /etc/modprobe.d with content:
-
-options easycap gain=16 bars=1
-install easycap /sbin/rmmod snd-usb-audio; /sbin/modprobe --ignore-install easycap
-
-
-ACKNOWLEGEMENTS AND REFERENCES
-------------------------------
-This driver makes use of information contained in the Syntek Semicon DC-1125
-Driver, presently maintained at http://sourceforge.net/projects/syntekdriver/
-by Nicolas Vivien. Particularly useful has been a patch to the latter driver
-provided by Ivor Hewitt in January 2009. The NTSC implementation is taken
-from the work of Ben Trask.
