# Utilities
Why: Unsupported/unmaintained/unused since 2.6
----------------------------
+
+What: V4L2 selections API target rectangle and flags unification, the
+ following definitions will be removed: V4L2_SEL_TGT_CROP_ACTIVE,
+ V4L2_SEL_TGT_COMPOSE_ACTIVE, V4L2_SUBDEV_SEL_*, V4L2_SUBDEV_SEL_FLAG_*
+ in favor of common V4L2_SEL_TGT_* and V4L2_SEL_FLAG_* definitions.
+ For more details see include/linux/v4l2-common.h.
+When: 3.8
+Why: The regular V4L2 selections and the subdev selection API originally
+ defined distinct names for the target rectangles and flags - V4L2_SEL_*
+ and V4L2_SUBDEV_SEL_*. Although, it turned out that the meaning of these
+ target rectangles is virtually identical and the APIs were consolidated
+ to use single set of names - V4L2_SEL_*. This didn't involve any ABI
+ changes. Alias definitions were created for the original ones to avoid
+ any instabilities in the user space interface. After few cycles these
+ backward compatibility definitions will be removed.
+Who: Sylwester Nawrocki <sylvester.nawrocki@gmail.com>
+

unlocked_ioctl file operation is called this lock will be taken by the
core and released afterwards. See the next section for more details.
+- queue: a pointer to the struct vb2_queue associated with this device node.
+ If queue is non-NULL, and queue->lock is non-NULL, then queue->lock is
+ used for the queuing ioctls (VIDIOC_REQBUFS, CREATE_BUFS, QBUF, DQBUF,
+ QUERYBUF, PREPARE_BUF, STREAMON and STREAMOFF) instead of the lock above.
+ That way the vb2 queuing framework does not have to wait for other ioctls.
+ This queue pointer is also used by the vb2 helper functions to check for
+ queuing ownership (i.e. is the filehandle calling it allowed to do the
+ operation).
+
- prio: keeps track of the priorities. Used to implement VIDIOC_G/S_PRIORITY.
If left to NULL, then it will use the struct v4l2_prio_state in v4l2_device.
If you want to have a separate priority state per (group of) device node(s),
A reference to the entity will be automatically acquired/released when the
video device is opened/closed.
-v4l2_file_operations and locking
---------------------------------
-
-You can set a pointer to a mutex_lock in struct video_device. Usually this
-will be either a top-level mutex or a mutex per device node. By default this
-lock will be used for unlocked_ioctl, but you can disable locking for
-selected ioctls by calling:
-
- void v4l2_disable_ioctl_locking(struct video_device *vdev, unsigned int cmd);
-
-E.g.: v4l2_disable_ioctl_locking(vdev, VIDIOC_DQBUF);
+ioctls and locking
+------------------
-You have to call this before you register the video_device.
+The V4L core provides optional locking services. The main service is the
+lock field in struct video_device, which is a pointer to a mutex. If you set
+this pointer, then that will be used by unlocked_ioctl to serialize all ioctls.
-Particularly with USB drivers where certain commands such as setting controls
-can take a long time you may want to do your own locking for the buffer queuing
-ioctls.
+If you are using the videobuf2 framework, then there is a second lock that you
+can set: video_device->queue->lock. If set, then this lock will be used instead
+of video_device->lock to serialize all queuing ioctls (see the previous section
+for the full list of those ioctls).
-If you want still finer-grained locking then you have to set mutex_lock to NULL
-and do you own locking completely.
+The advantage of using a different lock for the queuing ioctls is that for some
+drivers (particularly USB drivers) certain commands such as setting controls
+can take a long time, so you want to use a separate lock for the buffer queuing
+ioctls. That way your VIDIOC_DQBUF doesn't stall because the driver is busy
+changing the e.g. exposure of the webcam.
-It is up to the driver developer to decide which method to use. However, if
-your driver has high-latency operations (for example, changing the exposure
-of a USB webcam might take a long time), then you might be better off with
-doing your own locking if you want to allow the user to do other things with
-the device while waiting for the high-latency command to finish.
+Of course, you can always do all the locking yourself by leaving both lock
+pointers at NULL.
-If a lock is specified then all ioctl commands will be serialized on that
-lock. If you use videobuf then you must pass the same lock to the videobuf
-queue initialize function: if videobuf has to wait for a frame to arrive, then
-it will temporarily unlock the lock and relock it afterwards. If your driver
-also waits in the code, then you should do the same to allow other processes
-to access the device node while the first process is waiting for something.
+If you use the old videobuf then you must pass the video_device lock to the
+videobuf queue initialize function: if videobuf has to wait for a frame to
+arrive, then it will temporarily unlock the lock and relock it afterwards. If
+your driver also waits in the code, then you should do the same to allow other
+processes to access the device node while the first process is waiting for
+something.
In the case of videobuf2 you will need to implement the wait_prepare and
-wait_finish callbacks to unlock/lock if applicable. In particular, if you use
-the lock in struct video_device then you must unlock/lock this mutex in
-wait_prepare and wait_finish.
-
-The implementation of a hotplug disconnect should also take the lock before
-calling v4l2_device_disconnect.
+wait_finish callbacks to unlock/lock if applicable. If you use the queue->lock
+pointer, then you can use the helper functions vb2_ops_wait_prepare/finish.
+
+The implementation of a hotplug disconnect should also take the lock from
+video_device before calling v4l2_device_disconnect. If you are also using
+video_device->queue->lock, then you have to first lock video_device->queue->lock
+followed by video_device->lock. That way you can be sure no ioctl is running
+when you call v4l2_device_disconnect.
