Hello,
This patch set aims to:
* add initial support for Venus version 4xx (found on sdm845).
* introduce a common capability parser to enumerate better
supported uncompressed formats, capabilities by codec,
supported codecs and so on.
* also contains various cleanups, readability improvements
and fixes.
* adds HEVC codec support for the Venus versions which has
support for it.
* add multi-stream support (secondary decoder output), which
will give as an opportunity to use UBWC compressed formats
to optimize internal interconnect bandwidth on higher
resolutions.
I'm a bit confused about this: is this a purely driver-internal thing,
or is this exposed somehow to userspace as well? It seems to be purely
internal.
For now it'll be internal for the driver. In downstream driver it is
exposed to userspace via custom v4l_control but that is not generic and
I decided to not expose it.
regards,
Stan
