[Mesa-dev] [PATCH 0/8] nouveau: add support for vaapi

[Julien Isorce]

Currently nouveau does not support chunk decoding
which is required to support st/va

The following patches refactor nouveau_vp3_bsp
and nvc0_decoder_bsp in order to implement
pipe_video_codec::begin_frame/decode_bitstream/end_frame.
So that decode_bitstream can be call multiple times
between each begin/end.

TODO: apply same logic for nv98 but I do not have the
material to test it.

Julien Isorce (8):
  nouveau: extract memcpy loop from nouveau_vp3_bsp
  nouveau: remove nouveau_vp3_bsp to use begin/next/end
  nouveau: split nvc0_decoder_bsp in begin/next/end
  nouveau: preserve content buffer when calling nvc0_decoder_bsp_next
  nouveau: remove nvc0_decoder_bsp and use begin/next/end instead
  nvc0: implement pipe_video_codec::begin_frame/end_frame
  nouveau: fix chunk decoding by updating number of slices
  build: enable st/va with nouveau driver
