Unify flags on the selection interfaces on V4L2 and V4L2 subdev. Flags are very similar to targets in this case: there are more similarities than differences between the two interfaces. Signed-off-by:

Both V4L2 and V4L2 subdev interface have very similar selection APIs with differences foremost related to in-memory and media bus formats. However, the selection targets are the same for both. Most targets are and in the future will likely continue to be more the same than with any differences. Thus it makes sense to unify the documentation of the targets. Signed-off-by:

Change the users of V4L2_SUBDEV_SEL_TGT_* targets to use V4L2_SEL_TGT_* instead. The common definitions are moved to a new header file, include/linux/v4l2-common.h. Signed-off-by:

The string "_ACTUAL" does not say anything more about the target names. Drop it. V4L2 selection API was changed by "V4L: Remove "_ACTIVE" from the selection target name definitions" by Sylwester Nawrocki. This patch does the same for the V4L2 subdev API. Signed-off-by:

Sylwester Nawrocki authored
This patch drops the _ACTIVE part from the selection target names as a prerequisite to unify the selection target names across the subdev and regular video node API. The meaning of V4L2_SEL_TGT_*_ACTIVE and V4L2_SUBDEV_SEL_TGT_*_ACTUAL selection targets is logically the same. Different names add to confusion where both APIs are used in a single driver or an application. For some system configurations different names may lead to interoperability issues. For backwards compatibility V4L2_SEL_TGT_CROP_ACTIVE and V4L2_SEL_TGT_COMPOSE_ACTIVE are defined as aliases to V4L2_SEL_TGT_CROP and V4L2_SEL_TGT_COMPOSE. These aliases will be removed after deprecation period, according to Documentation/feature-removal-schedule.txt. Signed-off-by:

It's better to give platform code a chance to specify the allowed protocols to use. [mchehab@redhat.com: fix merge conflict with a patch that made half of this change] Signed-off-by:

current_norm can only be used if there is a single device node since it is local to the device node. In this case multiple device nodes share a single tuner. Signed-off-by:

- missing COMPRESSED flag for MPEG formats - set colorspace - set sizeimage - add tuner index checks - setup the frequency ranges correctly - add missing g_chip_ident ioctl - fix audmode handling - don't handle vbi formats on a video node and vice versa. cx88 now passes the v4l2-compliance tests.

This documents the new queue->lock and how to use it. It also removes the documentation of v4l2_disable_ioctl_locking: this is only used in gspca and will be removed once gspca has been converted to vb2. Signed-off-by:

Add helper functions to make it easier to adapt drivers to vb2. These helpers take care of core locking and check if the filehandle is the owner of the queue. Signed-off-by:
-
Hans Verkuil authored
This prepares struct video_device for easier integration with vb2. It also introduces a new lock that protects the vb2_queue. It is up to the driver to use it or not. And the driver can associate an owner filehandle with the queue to check whether queuing requests are permitted for the calling filehandle. Signed-off-by:

This also fixes incorrect error handling in create_bufs: the return code of __vb2_queue_alloc is the number of allocated buffers, and not a traditional error code. Signed-off-by:

Split off the memory and type validation. This is done both from reqbufs and create_bufs, and will also be done by vb2 helpers in a later patch. Signed-off-by:
