[PATCH v1 0/7] media: verisilicon: simplify auxiliary buffers allocation

Posted by Benjamin Gaignard 1 week, 1 day ago

Verisilicon stateless video decoder driver allocates lot of auxiliary
buffers to decode bitstreams. These allocations duplicate a lot of code.
This series add helpers functions to allocate and free auxiliary
buffers. This simplify the driver code and will allow to implement more
easly incoming feature like disentanglement data buffers from mv and rfc 
buffers or adding reference frame support for more codecs.

This series has been tested with fluster on IMX8MP for h264, hevc, vp8 
and vp9 codecs, and on rk3588 for av1.

This series depends of this one:
https://patchwork.linuxtv.org/project/linux-media/patch/20260910092021.139970-1-benjamin.gaignard@collabora.com/
which itself is based on media_tree/fixes branch.

Regards,
Benjamin
