Merged requested to merge airlied/mesa:anv-vulkan-video-decode into main
This is a working series to add support for H264 on gen9 Intel.
It's disabled by default, needs to be validated on newer hw and is missing at least one feature around status queries.
However I think it's a good baseline and took a lot of debugging to get this over the line.
I also have a port for hasvk but I'll await this landing first.
