media: visl: Add codec specific variability on output frames

2024-02-16T10:46:33Z

When running tests with different input data, the stable output frames could be too similar and hide possible issues. This commit adds variation by using some codec specific parameters. Only HEVC and H.264 support this. Reviewed-by: Daniel Almeida Signed-off-by: Detlev Casanova Signed-off-by: Hans Verkuil [hverkuil: add media: prefix to Subject]

media: visl: Add a tpg_verbose parameter

2024-02-16T10:46:33Z

The text written on the output frames stable for a given input. Remove the unstable elements like pointers, buffer indexes or queues status so that frames are always identical and can be compared against a reference in automatic tests. As the unstable information can be relevant when debugging the API, add a tpg_verbose parameter to show them.

media: visl,vidtv: Set parameters permissions to 0444

2024-02-16T10:46:33Z

This avoids confusion with default values and lets userspace programs get the modules parameters values at run time. This can be useful when setting up a test suite. Reviewed-by: Daniel Almeida Signed-off-by: Detlev Casanova Signed-off-by: Hans Verkuil

media: visl: Hook the (TRY_)DECODER_CMD stateless ioctls

2023-11-23T12:56:57Z

The (TRY_)DECODER_CMD ioctls are used to support flushing when holding capture buffers is supported. This is the case of this driver but the ioctls were never hooked to the ioctl ops. Add them to correctly support flushing.

This config option was added during the development of the Request API to make it easy to disable it. The Request API is now stable so it is time to drop this option altogether. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: test-drivers: Stop direct calls to queue num_buffers field

2023-11-23T11:31:54Z

Use vb2_get_num_buffers() to avoid using queue num_buffers field directly. This allows us to change how the number of buffers is computed in the future. If 'min_buffers_needed' is set remove useless checks in queue setup functions. Signed-off-by: Benjamin Gaignard CC: Daniel Almeida Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: visl: Use vb2_get_buffer() instead of directly access to buffers array

2023-11-23T11:06:22Z

Use vb2_get_buffer() instead of direct access to the vb2_queue bufs array. This allows us to change the type of the bufs in the future. After each call to vb2_get_buffer() we need to be sure that we get a valid pointer so check the return value of all of them.

media: visl-core: Convert to platform remove callback returning void

2023-04-11T14:59:21Z

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by: Uwe Kleine-König Signed-off-by: Hans Verkuil
