Isn't that what https://github.com/intel/intel-hybrid-driver is for? (at least, for VP9)
Indeed it is:

Note the presence of VAProfileVP9Profile0
in the second vainfo
output.
It appears that HEVC decode support is still not present, any news/progress?
Any progress?
https://forums.intel.com/s/question/0D50P0000490MoXSAU/intel-iris-and-hd-graphics-driver-update-posted-for-haswell-and-broadwell-version-1536144080?language=en_US
The changelog indicates that the Windows graphics driver supports "partial hardware" accelerated decode of VP9 and "GPU accelerated decode of HEVC" on Haswell and Broadwell. vainfo reports no support for either of the two on my Xeon E3-1276v3 Haswell CPU.
Could we get accelerated decoding support in the Linux driver? I imagine that it could be done vai a compute shader, which is likely what "GPU accelerated decode of HEVC" means.
