+
+ <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>
+
+ <para><constant>V4L2_PIX_FMT_YVU420M</constant> is intended to be
+used only in drivers and applications that support the multi-planar API,

+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.
+

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.
+

+HugeTLB Controller
+-------------------
+
+The HugeTLB controller allows to limit the HugeTLB usage per control group and
+enforces the controller limit during page fault. Since HugeTLB doesn't
+support page reclaim, enforcing the limit at page fault time implies that,
+the application will get SIGBUS signal if it tries to access HugeTLB pages
+beyond its limit. This requires the application to know beforehand how much
+HugeTLB pages it would require for its use.
+
+HugeTLB controller can be created by first mounting the cgroup filesystem.
+
+# mount -t cgroup -o hugetlb none /sys/fs/cgroup
+
+With the above step, the initial or the parent HugeTLB group becomes
+visible at /sys/fs/cgroup. At bootup, this group includes all the tasks in
+the system. /sys/fs/cgroup/tasks lists the tasks in this cgroup.
+
+New groups can be created under the parent group /sys/fs/cgroup.
+
+# cd /sys/fs/cgroup
+# mkdir g1
+# echo $$ > g1/tasks
+
+The above steps create a new group g1 and move the current shell
+process (bash) into it.

+VFIO - "Virtual Function I/O"[1]
+-------------------------------------------------------------------------------
+Many modern system now provide DMA and interrupt remapping facilities
+to help ensure I/O devices behave within the boundaries they've been
+allotted. This includes x86 hardware with AMD-Vi and Intel VT-d,
+POWER systems with Partitionable Endpoints (PEs) and embedded PowerPC
+systems such as Freescale PAMU. The VFIO driver is an IOMMU/device
+agnostic framework for exposing direct device access to userspace, in
+a secure, IOMMU protected environment. In other words, this allows
+safe[2], non-privileged, userspace drivers.
+
+Why do we want that? Virtual machines often make use of direct device
+access ("device assignment") when configured for the highest possible
+I/O performance. From a device and host perspective, this simply
+turns the VM into a userspace driver, with the benefits of
+significantly reduced latency, higher bandwidth, and direct use of
+bare-metal device drivers[3].
+
+Some applications, particularly in the high performance computing
+field, also benefit from low-overhead, direct device access from
+userspace. Examples include network adapters (often non-TCP/IP based)
+and compute accelerators. Prior to VFIO, these drivers had to either
+go through the full development cycle to become proper upstream
+driver, be maintained out of tree, or make use of the UIO framework,
+which has no notion of IOMMU protection, limited interrupt support,
+and requires root privileges to access things like PCI configuration
+space.
+
+The VFIO driver framework intends to unify these, replacing both the
+KVM PCI specific device assignment code as well as provide a more
+secure, more featureful userspace driver environment than UIO.
+
+Groups, Devices, and IOMMUs
+-------------------------------------------------------------------------------
+
+Devices are the main target of any I/O driver. Devices typically
+create a programming interface made up of I/O access, interrupts,
+and DMA. Without going into the details of each of these, DMA is
+by far the most critical aspect for maintaining a secure environment
+as allowing a device read-write access to system memory imposes the
+greatest risk to the overall system integrity.
+
+To help mitigate this risk, many modern IOMMUs now incorporate
+isolation properties into what was, in many cases, an interface only
+meant for translation (ie. solving the addressing problems of devices
+with limited address spaces). With this, devices can now be isolated
+from each other and from arbitrary memory access, thus allowing
+things like secure direct assignment of devices into virtual machines.
+
+This isolation is not always at the granularity of a single device
+though. Even when an IOMMU is capable of this, properties of devices,
+interconnects, and IOMMU topologies can each reduce this isolation.
+For instance, an individual device may be part of a larger multi-
+function enclosure. While the IOMMU may be able to distinguish
+between devices within the enclosure, the enclosure may not require
+transactions between devices to reach the IOMMU. Examples of this
+could be anything from a multi-function PCI device with backdoors
+between functions to a non-PCI-ACS (Access Control Services) capable
+bridge allowing redirection without reaching the IOMMU. Topology
+can also play a factor in terms of hiding devices. A PCIe-to-PCI
+bridge masks the devices behind it, making transaction appear as if
+from the bridge itself. Obviously IOMMU design plays a major factor
+as well.
+
+Therefore, while for the most part an IOMMU may have device level
+granularity, any system is susceptible to reduced granularity. The
+IOMMU API therefore supports a notion of IOMMU groups. A group is
+a set of devices which is isolatable from all other devices in the
+system. Groups are therefore the unit of ownership used by VFIO.
+
+While the group is the minimum granularity that must be used to
+ensure secure user access, it's not necessarily the preferred
+granularity. In IOMMUs which make use of page tables, it may be
+possible to share a set of page tables between different groups,
+reducing the overhead both to the platform (reduced TLB thrashing,
+reduced duplicate page tables), and to the user (programming only
+a single set of translations). For this reason, VFIO makes use of
+a container class, which may hold one or more groups. A container
+is created by simply opening the /dev/vfio/vfio character device.
+
+On its own, the container provides little functionality, with all
+but a couple version and extension query interfaces locked away.
+The user needs to add a group into the container for the next level
+of functionality. To do this, the user first needs to identify the
+group associated with the desired device. This can be done using
+the sysfs links described in the example below. By unbinding the
+device from the host driver and binding it to a VFIO driver, a new
+VFIO group will appear for the group as /dev/vfio/$GROUP, where
+$GROUP is the IOMMU group number of which the device is a member.
+If the IOMMU group contains multiple devices, each will need to
+be bound to a VFIO driver before operations on the VFIO group
+are allowed (it's also sufficient to only unbind the device from
+host drivers if a VFIO driver is unavailable; this will make the
+group available, but not that particular device). TBD - interface
+for disabling driver probing/locking a device.
+
+Once the group is ready, it may be added to the container by opening
+the VFIO group character device (/dev/vfio/$GROUP) and using the
+VFIO_GROUP_SET_CONTAINER ioctl, passing the file descriptor of the
+previously opened container file. If desired and if the IOMMU driver
+supports sharing the IOMMU context between groups, multiple groups may
+be set to the same container. If a group fails to set to a container
+with existing groups, a new empty container will need to be used
+instead.
+
+With a group (or groups) attached to a container, the remaining
+ioctls become available, enabling access to the VFIO IOMMU interfaces.
+Additionally, it now becomes possible to get file descriptors for each
+device within a group using an ioctl on the VFIO group file descriptor.
+
+The VFIO device API includes ioctls for describing the device, the I/O
+regions and their read/write/mmap offsets on the device descriptor, as
+well as mechanisms for describing and registering interrupt
+notifications.
+
+VFIO Usage Example
+-------------------------------------------------------------------------------
+
+Assume user wants to access PCI device 0000:06:0d.0
+
+$ readlink /sys/bus/pci/devices/0000:06:0d.0/iommu_group
+../../../../kernel/iommu_groups/26
+
+This device is therefore in IOMMU group 26. This device is on the
+pci bus, therefore the user will make use of vfio-pci to manage the
+group:
+
+# modprobe vfio-pci
+
+Binding this device to the vfio-pci driver creates the VFIO group
+character devices for this group:
+
+$ lspci -n -s 0000:06:0d.0
+06:0d.0 0401: 1102:0002 (rev 08)
+# echo 0000:06:0d.0 > /sys/bus/pci/devices/0000:06:0d.0/driver/unbind
+# echo 1102 0002 > /sys/bus/pci/drivers/vfio-pci/new_id
+
+Now we need to look at what other devices are in the group to free
+it for use by VFIO:
+
+$ ls -l /sys/bus/pci/devices/0000:06:0d.0/iommu_group/devices
+total 0
+lrwxrwxrwx. 1 root root 0 Apr 23 16:13 0000:00:1e.0 ->
+ ../../../../devices/pci0000:00/0000:00:1e.0
+lrwxrwxrwx. 1 root root 0 Apr 23 16:13 0000:06:0d.0 ->
+ ../../../../devices/pci0000:00/0000:00:1e.0/0000:06:0d.0
+lrwxrwxrwx. 1 root root 0 Apr 23 16:13 0000:06:0d.1 ->
+ ../../../../devices/pci0000:00/0000:00:1e.0/0000:06:0d.1
+
+This device is behind a PCIe-to-PCI bridge[4], therefore we also
+need to add device 0000:06:0d.1 to the group following the same
+procedure as above. Device 0000:00:1e.0 is a bridge that does
+not currently have a host driver, therefore it's not required to
+bind this device to the vfio-pci driver (vfio-pci does not currently
+support PCI bridges).
+
+The final step is to provide the user with access to the group if
+unprivileged operation is desired (note that /dev/vfio/vfio provides
+no capabilities on its own and is therefore expected to be set to
+mode 0666 by the system).
+
+# chown user:user /dev/vfio/26
+
+The user now has full access to all the devices and the iommu for this
+group and can access them as follows:
+
+ int container, group, device, i;
+ struct vfio_group_status group_status =
+ { .argsz = sizeof(group_status) };

+ dma_map.size = 1024 * 1024;
+ dma_map.iova = 0; /* 1MB starting at 0x0 from device view */
+ dma_map.flags = VFIO_DMA_MAP_FLAG_READ | VFIO_DMA_MAP_FLAG_WRITE;
+
+ ioctl(container, VFIO_IOMMU_MAP_DMA, &dma_map);
+
+ /* Get a file descriptor for the device */
+ device = ioctl(group, VFIO_GROUP_GET_DEVICE_FD, "0000:06:0d.0");
+

+

+

+ }
+

+
+VFIO User API
+-------------------------------------------------------------------------------
+
+Please see include/linux/vfio.h for complete API documentation.
+
+VFIO bus driver API
+-------------------------------------------------------------------------------
+
+VFIO bus drivers, such as vfio-pci make use of only a few interfaces
+into VFIO core. When devices are bound and unbound to the driver,
+the driver should call vfio_add_group_dev() and vfio_del_group_dev()
+respectively:
+
+extern int vfio_add_group_dev(struct iommu_group *iommu_group,
+ struct device *dev,
+ const struct vfio_device_ops *ops,
+ void *device_data);
+
+extern void *vfio_del_group_dev(struct device *dev);
+
+vfio_add_group_dev() indicates to the core to begin tracking the
+specified iommu_group and register the specified dev as owned by
+a VFIO bus driver. The driver provides an ops structure for callbacks
+similar to a file operations structure:
+
+struct vfio_device_ops {
+ int (*open)(void *device_data);
+ void (*release)(void *device_data);
+ ssize_t (*read)(void *device_data, char __user *buf,
+ size_t count, loff_t *ppos);
+ ssize_t (*write)(void *device_data, const char __user *buf,
+ size_t size, loff_t *ppos);
+ long (*ioctl)(void *device_data, unsigned int cmd,
+ unsigned long arg);
+ int (*mmap)(void *device_data, struct vm_area_struct *vma);
+};
+
+Each function is passed the device_data that was originally registered
+in the vfio_add_group_dev() call above. This allows the bus driver
+an easy place to store its opaque, private data. The open/release
+callbacks are issued when a new file descriptor is created for a
+device (via VFIO_GROUP_GET_DEVICE_FD). The ioctl interface provides
+a direct pass through for VFIO_DEVICE_* ioctls. The read/write/mmap
+interfaces implement the device region access defined by the device's
+own VFIO_DEVICE_GET_REGION_INFO ioctl.
+
+-------------------------------------------------------------------------------
+
+[1] VFIO was originally an acronym for "Virtual Function I/O" in its
+initial implementation by Tom Lyon while as Cisco. We've since
+outgrown the acronym, but it's catchy.
+
+[2] "safe" also depends upon a device being "well behaved". It's
+possible for multi-function devices to have backdoors between
+functions and even for single function devices to have alternative
+access to things like PCI config space through MMIO registers. To
+guard against the former we can include additional precautions in the
+IOMMU driver to group multi-function PCI devices together
+(iommu=group_mf). The latter we can't prevent, but the IOMMU should
+still provide isolation. For PCI, SR-IOV Virtual Functions are the
+best indicator of "well behaved", as these are designed for
+virtualization usage models.
+
+[3] As always there are trade-offs to virtual machine device
+assignment that are beyond the scope of VFIO. It's expected that
+future IOMMU technologies will reduce some, but maybe not all, of
+these trade-offs.
+
+[4] In this case the device is below a PCI bridge, so transactions
+from either function of the device are indistinguishable to the iommu:

- * arch/alpha/lib/ev6-strncpy_from_user.S
- * 21264 version contributed by Rick Gorton <rick.gorton@alpha-processor.com>
- *
- * Just like strncpy except in the return value:
- *
- * -EFAULT if an exception occurs before the terminator is copied.
- * N if the buffer filled.
- *
- * Otherwise the length of the string is returned.
- *
- * Much of the information about 21264 scheduling/coding comes from:
- * Compiler Writer's Guide for the Alpha 21264
- * abbreviated as 'CWG' in other comments here
- * ftp.digital.com/pub/Digital/info/semiconductor/literature/dsc-library.html
- * Scheduling notation:
- * E - either cluster
- * U - upper subcluster; U0 - subcluster U0; U1 - subcluster U1
- * L - lower subcluster; L0 - subcluster L0; L1 - subcluster L1
- * A bunch of instructions got moved and temp registers were changed
- * to aid in scheduling. Control flow was also re-arranged to eliminate
- * branches, and to provide longer code sequences to enable better scheduling.
- * A total rewrite (using byte load/stores for start & tail sequences)
- * is desirable, but very difficult to do without a from-scratch rewrite.
- * Save that for the future.

- * NOTES about DMA transfers:
- *
- * controller 1: channels 0-3, byte operations, ports 00-1F
- * controller 2: channels 4-7, word operations, ports C0-DF
- *
- * - ALL registers are 8 bits only, regardless of transfer size
- * - channel 4 is not used - cascades 1 into 2.
- * - channels 0-3 are byte - addresses/counts are for physical bytes
- * - channels 5-7 are word - addresses/counts are for physical words
- * - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
- * - transfer count loaded to registers is 1 less than actual count
- * - controller 2 offsets are all even (2x offsets for controller 1)
- * - page registers for 5-7 don't use data bit 0, represent 128K pages
- * - page registers for 0-3 use bit 0, represent 64K pages
- *
- * DMA transfers are limited to the lower 16MB of _physical_ memory.
- * Note that addresses loaded into registers must be _physical_ addresses,
- * not logical addresses (which may differ if paging is active).
- *
- * Address mapping for channels 0-3:
- *
- * A23 ... A16 A15 ... A8 A7 ... A0 (Physical addresses)
- * | ... | | ... | | ... |
- * | ... | | ... | | ... |
- * | ... | | ... | | ... |
- * P7 ... P0 A7 ... A0 A7 ... A0
- * | Page | Addr MSB | Addr LSB | (DMA registers)
- *
- * Address mapping for channels 5-7:
- *
- * A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0 (Physical addresses)
- * | ... | \ \ ... \ \ \ ... \ \
- * | ... | \ \ ... \ \ \ ... \ (not used)
- * | ... | \ \ ... \ \ \ ... \
- * P7 ... P1 (0) A7 A6 ... A0 A7 A6 ... A0
- * | Page | Addr MSB | Addr LSB | (DMA registers)
- *
- * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
- * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
- * the hardware level, so odd-byte transfers aren't possible).
- *
- * Transfer count (_not # bytes_) is limited to 64K, represented as actual
- * count - 1 : 64K => 0xFFFF, 1 => 0x0000. Thus, count is always 1 or more,
- * and up to 128K bytes may be transferred on channels 5-7 in one operation.

- * The pfn containing the shared_info is located somewhere in RAM. This

- * 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

- Maximum number of DVB/ATSC adapters. Increasing this number
- increases the memory consumption of the DVB subsystem even
- if a much lower number of DVB/ATSC adapters is present.
- Only values in the range 4-32 are tested.

- If you say Y here, the DVB subsystem will use dynamic minor
- allocation for any device that uses the DVB major number.
- This means that you can have more than 4 of a single type
- of device (like demuxes and frontends) per adapter, but udev
- will be required to manage the device nodes.

- If you are unsure about this, say N here.

+ Support for PCI cards based on the Bt8xx PCI bridge. Examples are
+ the Nebula cards, the Pinnacle PCTV cards, the Twinhan DST cards,
+ the pcHDTV HD2000 cards, the DViCO FusionHDTV Lite cards, and
+ some AVerMedia cards.
+
+ Since these cards have no MPEG decoder onboard, they transmit
+ only compressed MPEG data over the PCI bus, so you need
+ an external software decoder to watch TV on your computer.
+
+ Say Y if you own such a device and want to use it.

- This enables PWM support through the generic PWM framework.
- You only need to enable this, if you also want to enable
- one or more of the PWM drivers below.
+ Generic Pulse-Width Modulation (PWM) support.
- If unsure, say N.
+ In Pulse-Width Modulation, a variation of the width of pulses
+ in a rectangular pulse signal is used as a means to alter the
+ average power of the signal. Applications include efficient
+ power delivery and voltage regulation. In computer systems,
+ PWMs are commonly used to control fans or the brightness of
+ display backlights.
+
+ This framework provides a generic interface to PWM devices
+ within the Linux kernel. On the driver side it provides an API
+ to register and unregister a PWM chip, an abstraction of a PWM
+ controller, that supports one or more PWM devices. Client
+ drivers can request PWM devices and use the generic framework
+ to configure as well as enable and disable them.
+
+ This generic framework replaces the legacy PWM framework which
+ allows only a single driver implementing the required API. Not
+ all legacy implementations have been ported to the framework
+ yet. The framework provides an API that is backward compatible
+ with the legacy framework so that existing client drivers
+ continue to work as expected.
+
+ If unsure, say no.

- * and *
- * EasyCAP002 4-Channel USB 2.0 DVR *
- ***********************************************************
- Mike Thomas <rmthomas@sciolus.org>
-
-
-
-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.

- * Currently the driver reduces the sampling rate by factor of 8 as this

- * But the driver does not rely on RC-5 it should be able to decode every

+ * We arbitrarily define a Type1 IOMMU as one matching the below code.
+ * It could be called the x86 IOMMU as it's designed for AMD-Vi & Intel
+ * VT-d, but that makes it harder to re-use as theoretically anyone
+ * implementing a similar IOMMU could make use of this. We expect the
+ * IOMMU to support the IOMMU API and have few to no restrictions around
+ * the IOVA range that can be mapped. The Type1 IOMMU is currently
+ * optimized for relatively static mappings of a userspace process with
+ * userpsace pages pinned into memory. We also assume devices and IOMMU
+ * domains are PCI based as the IOMMU API is still centered around a
+ * device/bus interface rather than a group interface.

+ * Set signaling, masking, and unmasking of interrupts. Caller provides
+ * struct vfio_irq_set with all fields set. 'start' and 'count' indicate
+ * the range of subindexes being specified.
+ *
+ * The DATA flags specify the type of data provided. If DATA_NONE, the
+ * operation performs the specified action immediately on the specified
+ * interrupt(s). For example, to unmask AUTOMASKED interrupt [0,0]:
+ * flags = (DATA_NONE|ACTION_UNMASK), index = 0, start = 0, count = 1.
+ *
+ * DATA_BOOL allows sparse support for the same on arrays of interrupts.
+ * For example, to mask interrupts [0,1] and [0,3] (but not [0,2]):
+ * flags = (DATA_BOOL|ACTION_MASK), index = 0, start = 1, count = 3,
+ * data = {1,0,1}
+ *
+ * DATA_EVENTFD binds the specified ACTION to the provided __s32 eventfd.
+ * A value of -1 can be used to either de-assign interrupts if already
+ * assigned or skip un-assigned interrupts. For example, to set an eventfd
+ * to be trigger for interrupts [0,0] and [0,2]:
+ * flags = (DATA_EVENTFD|ACTION_TRIGGER), index = 0, start = 0, count = 3,
+ * data = {fd1, -1, fd2}
+ * If index [0,1] is previously set, two count = 1 ioctls calls would be
+ * required to set [0,0] and [0,2] without changing [0,1].
+ *
+ * Once a signaling mechanism is set, DATA_BOOL or DATA_NONE can be used
+ * with ACTION_TRIGGER to perform kernel level interrupt loopback testing
+ * from userspace (ie. simulate hardware triggering).
+ *
+ * Setting of an event triggering mechanism to userspace for ACTION_TRIGGER
+ * enables the interrupt index for the device. Individual subindex interrupts
+ * can be disabled using the -1 value for DATA_EVENTFD or the index can be
+ * disabled as a whole with: flags = (DATA_NONE|ACTION_TRIGGER), count = 0.
+ *
+ * Note that ACTION_[UN]MASK specify user->kernel signaling (irqfds) while
+ * ACTION_TRIGGER specifies kernel->user signaling.
