Video4Linux2 defines 3 RGB formats with 10 bits per color components plus two optional alpha bits such that a pixel is then stored in a 4 bytes word. Add a format info for the 3 10-bits RGB formats to the v4l2_format_info() table in v4l2-common.c. Signed-off-by:

When ioctl debugging is turned on, the v4l_printk_ioctl() is used to log the ioctl that is called. It uses an array of ioctl information to log the ioctl name and it correctly checks for out-of-bound indexing of that array. However, the array may have holes since not all ioctl numbers are used. In that case the name of the ioctl is NULL. It is harmless (printk handles NULL pointers), but not intended. Instead use the v4l2_is_known_ioctl() function to determine if the ioctl information is available or not. Signed-off-by:

Count how many Low Drive, Error and Arbitration Lost transmit status errors occurred, and expose that in debugfs. Also log the first 8 transmits that result in Low Drive or Error conditions. That really should not happen with well-behaved CEC devices and good HDMI cables. This is useful to detect and debug HDMI cable issues. Signed-off-by:

Remove all checks that prohibit to set a new format while streaming. This allow to change dynamically the resolution if the pixel format remains the same. Signed-off-by:

HEVC and VP9 are running on the same hardware and share the same chroma and motion vectors offset constraint. Create common helpers functions for these computation. Source and destination buffer height may not be the same because alignment constraint are different so use destination height to compute chroma offset because we target this buffer as hardware output. To be able to use the helpers in both VP9 HEVC code remove dec_params and use context->bit_depth instead. Signed-off-by:

Store computed values of chroma and motion vectors offset because they depends on width and height values which change if the resolution change. Signed-off-by:

Since vb2 queue can store more than VB2_MAX_FRAME buffers, the postprocessor buffer storage must be capable to store more buffers too. Change static dec_q array to allocated array to be capable to store up to queue 'max_num_buffers'. Keep allocating queue 'num_buffers' at queue setup time but also allows to allocate postprocessors buffers on the fly. Signed-off-by:

Change the maximum number of buffers of some capture queues in order to test max_num_buffers field. Allow to allocate up to: - 64 buffers for video capture queue. - 1024 buffers for sdr capture queue. - 32768 buffers for vbi capture queue. Signed-off-by:

Use one of the struct v4l2_create_buffers reserved bytes to report the maximum possible number of buffers for the queue. V4l2 framework set V4L2_BUF_CAP_SUPPORTS_MAX_NUM_BUFFERS flags in queue capabilities so userland can know when the field is valid. Does the same change in v4l2_create_buffers32 structure.

Add 'max_num_buffers' field in vb2_queue struct to let drivers decide how many buffers could be stored in a queue. This require 'bufs' array to be allocated at queue init time and freed when releasing the queue. By default VB2_MAX_FRAME remains the limit. Signed-off-by:
