[media] v4l2-core: drop g/s_priority ops

2015-03-02T20:09:43+00:00

The handling of VIDIOC_G/S_PRIORITY is now entirely done by the V4L2 core, so we can drop the g/s_priority ioctl ops. We do have to make sure though that when S_PRIORITY is called we check that the driver used struct v4l2_fh. This check can be removed once all drivers are converted to that structure.

[media] v4l2 core: improve debug flag handling

2014-12-23T12:31:37+00:00

The old debug field is renamed to dev_debug to ensure that existing drivers (including out-of-tree drivers) that try to use the old name will no longer compile. A comment has also been added that makes it explicit that drivers shouldn't use this field. Additional bits have been added to the debug flag to be more fine-grained when debugging, especially when dealing with streaming ioctls and read, write and poll. You want to enable those explicitly to prevent flooding the log when streaming unless you actually want to do that.

[media] v4l2: integrate support for VIDIOC_QUERY_EXT_CTRL

2014-07-17T13:38:44+00:00

Add the v4l2 core plumbing for the new VIDIOC_QUERY_EXT_CTRL ioctl. Signed-off-by: Hans Verkuil Reviewed-by: Sylwester Nawrocki Signed-off-by: Mauro Carvalho Chehab

[media] v4l2: add VIDIOC_G/S_EDID support to the v4l2 core

2014-03-11T13:06:53+00:00

Support this ioctl as part of the v4l2 core. Use the new ioctl name and struct v4l2_edid type in the existing core code. Signed-off-by: Hans Verkuil Acked-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] v4l: define own IOCTL ops for SDR FMT

2014-03-05T17:15:16+00:00

Use own format ops for SDR data: vidioc_enum_fmt_sdr_cap vidioc_g_fmt_sdr_cap vidioc_s_fmt_sdr_cap vidioc_try_fmt_sdr_cap Signed-off-by: Antti Palosaari Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-core: remove support for obsolete VIDIOC_DBG_G_CHIP_IDENT

2013-06-21T13:46:44+00:00

This has been replaced by the new and much better VIDIOC_DBG_G_CHIP_INFO. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2: rename VIDIOC_DBG_G_CHIP_NAME to _CHIP_INFO

2013-04-14T22:47:33+00:00

This ioctl will be extended to return more information than just the name. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2: put VIDIOC_DBG_G_CHIP_NAME under ADV_DEBUG

2013-04-14T22:45:23+00:00

Only enable this ioctl if the VIDEO_ADV_DEBUG config option is set. This prevents abuse from both userspace and kernelspace (some bridge drivers abuse DBG_G_CHIP_IDENT, lets prevent that from happening again with this ioctl). Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] ioctl numbers are unsigned int

[media] v4l2: add new VIDIOC_DBG_G_CHIP_NAME ioctl

2013-03-25T12:31:05+00:00

Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl. This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done by the name or index of subdevices or an index to a bridge chip. Most of this can all be done automatically, so most drivers just need to provide get/set register ops. In particular, it is now possible to get/set subdev registers without requiring assistance of the bridge driver. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
