+
+ <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>

-Produced by user requests:
+In the above chart minuses and slashes represent "real" data amounts, points and
+accents represent "useful" data, basically, CEU scaled amd cropped output,
+mapped back onto the client's source plane.
+
+Such a configuration can be produced by user requests:
S_CROP(left / top = (5) - (1), width / height = (5') - (5))
S_FMT(width / height = (6') - (6))
S_CROP
------
-If old scale applied to new crop is invalid produce nearest new scale possible
-
-1. Calculate current combined scales.
-
- scale_comb = (((4') - (4)) / ((6') - (6))) * (((2') - (2)) / ((3') - (3)))
-
-2. Apply iterative sensor S_CROP for new input window.
-
-3. If old combined scales applied to new crop produce an impossible user window,
-adjust scales to produce nearest possible window.
-
- width_u_out = ((5') - (5)) / scale_comb
+The API at http://v4l2spec.bytesex.org/spec/x1904.htm says:
- if (width_u_out > max)
- scale_comb = ((5') - (5)) / max;
- else if (width_u_out < min)
- scale_comb = ((5') - (5)) / min;
+"...specification does not define an origin or units. However by convention
+drivers should horizontally count unscaled samples relative to 0H."
-4. Issue G_CROP to retrieve actual input window.
+We choose to follow the advise and interpret cropping units as client input
+pixels.
-5. Using actual input window and calculated combined scales calculate sensor
-target output window.
-
- width_s_out = ((3') - (3)) = ((2') - (2)) / scale_comb
-
-6. Apply iterative S_FMT for new sensor target output window.
-
-7. Issue G_FMT to retrieve the actual sensor output window.
-
-8. Calculate sensor scales.
-
- scale_s = ((3') - (3)) / ((2') - (2))
+Cropping is performed in the following 6 steps:
-9. Calculate sensor output subwindow to be cropped on CEU by applying sensor
-scales to the requested window.
+1. Request exactly user rectangle from the sensor.
- width_ceu = ((5') - (5)) / scale_s
+2. If smaller - iterate until a larger one is obtained. Result: sensor cropped
+ to 2 : 2', target crop 5 : 5', current output format 6' - 6.
-10. Use CEU cropping for above calculated window.
+3. In the previous step the sensor has tried to preserve its output frame as
+ good as possible, but it could have changed. Retrieve it again.
-11. Calculate CEU scales from sensor scales from results of (10) and user window
-from (3)
+4. Sensor scaled to 3 : 3'. Sensor's scale is (2' - 2) / (3' - 3). Calculate
+ intermediate window: 4' - 4 = (5' - 5) * (3' - 3) / (2' - 2)
- scale_ceu = calc_scale(((5') - (5)), &width_u_out)
+5. Calculate and apply host scale = (6' - 6) / (4' - 4)
-12. Apply CEU scales.
+6. Calculate and apply host crop: 6 - 7 = (5 - 2) * (6' - 6) / (5' - 5)

This will remove the device nodes from sysfs (causing udev to remove them
from /dev).
-After video_unregister_device() returns no new opens can be done.
-
-However, in the case of USB devices some application might still have one
-of these device nodes open. You should block all new accesses to read,
-write, poll, etc. except possibly for certain ioctl operations like
-queueing buffers.
+After video_unregister_device() returns no new opens can be done. However,
+in the case of USB devices some application might still have one of these
+device nodes open. So after the unregister all file operations will return
+an error as well, except for the ioctl and unlocked_ioctl file operations:
+those will still be passed on since some buffer ioctls may still be needed.
When the last user of the video device node exits, then the vdev->release()
callback is called and you can do the final cleanup there.
Please see Documentation/video4linux/videobuf for more information on how
to use the videobuf layer.
+
+struct v4l2_fh
+--------------
+
+struct v4l2_fh provides a way to easily keep file handle specific data
+that is used by the V4L2 framework. Using v4l2_fh is optional for
+drivers.
+
+The users of v4l2_fh (in the V4L2 framework, not the driver) know
+whether a driver uses v4l2_fh as its file->private_data pointer by
+testing the V4L2_FL_USES_V4L2_FH bit in video_device->flags.
+
+Useful functions:
+
+- v4l2_fh_init()
+
+ Initialise the file handle. This *MUST* be performed in the driver's
+ v4l2_file_operations->open() handler.
+
+- v4l2_fh_add()
+
+ Add a v4l2_fh to video_device file handle list. May be called after
+ initialising the file handle.
+
+- v4l2_fh_del()
+
+ Unassociate the file handle from video_device(). The file handle
+ exit function may now be called.
+
+- v4l2_fh_exit()
+
+ Uninitialise the file handle. After uninitialisation the v4l2_fh
+ memory can be freed.
+
+struct v4l2_fh is allocated as a part of the driver's own file handle
+structure and is set to file->private_data in the driver's open
+function by the driver. Drivers can extract their own file handle
+structure by using the container_of macro. Example:
+
+struct my_fh {
+ int blah;
+ struct v4l2_fh fh;
+};
+
+...
+
+int my_open(struct file *file)
+{
+ struct my_fh *my_fh;
+ struct video_device *vfd;
+ int ret;
+
+ ...
+
+ ret = v4l2_fh_init(&my_fh->fh, vfd);
+ if (ret)
+ return ret;
+
+ v4l2_fh_add(&my_fh->fh);
+
+ file->private_data = &my_fh->fh;
+
+ ...
+}
+
+int my_release(struct file *file)
+{
+ struct v4l2_fh *fh = file->private_data;
+ struct my_fh *my_fh = container_of(fh, struct my_fh, fh);
+
+ ...
+}
+
+V4L2 events
+-----------
+
+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:
+
+- v4l2_event_alloc()
+
+ To use events, the driver must allocate events for the file handle. By
+ calling the function more than once, the driver may assure that at least n
+ events in total have been allocated. The function may not be called in
+ atomic context.
+
+- v4l2_event_queue()
+
+ Queue events to video device. The driver's only responsibility is to fill
+ in the type and the data fields. The other fields will be filled in by
+ V4L2.
+
+- v4l2_event_subscribe()
+
+ The video_device->ioctl_ops->vidioc_subscribe_event must check the driver
+ is able to produce events with specified event id. Then it calls
+ v4l2_event_subscribe() to subscribe the event.
+
+- v4l2_event_unsubscribe()
+
+ vidioc_unsubscribe_event in struct v4l2_ioctl_ops. A driver may use
+ v4l2_event_unsubscribe() directly unless it wants to be involved in
+ unsubscription process.
+
+ The special type V4L2_EVENT_ALL may be used to unsubscribe all events. The
+ drivers may want to handle this in a special way.
+
+- v4l2_event_pending()
+
+ Returns the number of pending events. Useful when implementing poll.
+
+Drivers do not initialise events directly. The events are initialised
+through v4l2_fh_init() if video_device->ioctl_ops->vidioc_subscribe_event is
+non-NULL. This *MUST* be performed in the driver's
+v4l2_file_operations->open() handler.
+
+Events are delivered to user space through the poll system call. The driver
+can use v4l2_fh->events->wait wait_queue_head_t as the argument for
+poll_wait().
+
+There are standard and private events. New standard events must use the
+smallest available event type. The drivers must allocate their events from
+their own class starting from class base. Class base is
+V4L2_EVENT_PRIVATE_START + n * 1000 where n is the lowest available number.
+The first event type in the class is reserved for future use, so the first
+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 available at <URL:http://gitorious.org/omap3camera> as of
+writing this.
