media: vimc: cap: check v4l2_fill_pixfmt return value

2019-07-26T07:10:33+00:00

[ Upstream commit 77ae46e11df5c96bb4582633851f838f5d954df4 ] v4l2_fill_pixfmt() returns -EINVAL if the pixelformat used as parameter is invalid or if the user is trying to use a multiplanar format with the singleplanar API. Currently, the vimc_cap_try_fmt_vid_cap() returns such value, but vimc_cap_s_fmt_vid_cap() is ignoring it. Fix that and returns an error value if vimc_cap_try_fmt_vid_cap() has failed.

media: vimc: propagate pixel format in the stream

2019-04-22T14:58:51+00:00

Media bus codes were being mapped to pixelformats, which causes a limitation on vimc because not all pixelformats can be mapped to media bus codes. Also, media bus codes are an internal configuration from the device. Userspace only assures media bus codes matches between pads and expects the image in a given pixelformat. So we can allow almost any media bus format to be configured between pads, except for debayer that expects a media bus code of type bayer in the sink pad.

Don't free vimc_cap_device immediately, instead do this in the video_device release function which is called when the last user closes the video device. Only then is it safe to free the memory. Signed-off-by: Hans Verkuil Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: vimc: fill in bus_info in media_device_info

2019-02-07T17:38:59+00:00

It is good practice to fill in bus_info. Also just use 'platform:vimc' when filling in the bus_info in querycap: the bus_info has nothing to do with the video device name. Signed-off-by: Hans Verkuil Acked-by: Helen Koike Signed-off-by: Mauro Carvalho Chehab

media: vimc: Add vimc-streamer for stream control

2019-02-07T17:23:09+00:00

Add a linear pipeline logic for the stream control. It's created by walking backwards on the entity graph. When the stream starts it will simply loop through the pipeline calling the respective process_frame function of each entity.
