Subject: [PATCH v2 00/11] media: cedrus: Format handling improvements and 10-bit HEVC support
Date: Wed,  2 Nov 2022 19:07:59 +0100	[thread overview]
Message-ID: <20221102180810.267252-1-jernej.skrabec@gmail.com> (raw)

While my first intention was to just add 10-bit HEVC handling, I noticed
a few format handling issues and a bit of redundancy in some cases. Final
result is that driver now sticks to stateless decoder rules better.

Format handling improvements:
1. Default format selection is now based on HW capabilities. Before, MPEG2
   was hardcoded but some Cedrus variants don't actually support it.
2. Controls are registered only if related codec is supported by HW.
3. Untiled output format is preferred, if supported, over tiled one. All
   display engine cores support untiled format, but only first generation
   supports tiled one.

I hope this makes Cedrus eligible for destaging.

Best regards,
Jernej

Changes from v1:
- collected acks, except for patch 5, which was changed
- use cedrus_is_capable() for cedrus_find_format() too (patch 4)
- tightly pack control pointers in ctx->ctrls[] (patch 5)

Jernej Skrabec (11):
