[Mesa-dev] [PATCH v2 0/3] st: dri2: handle dmabuf plane offsets != 0

[Stanimir Varbanov]

Changes since v1:
  - in 2/3 make possible to pass NULL pointer for error
    argument to cover cases when exact error code is not
    needed.
  - in 3/3 avoid adding drm_driver.h by going down to winsys
    abstraction layer for the drivers which supporting it,
    removed check winsys->offset != for r300 and radeon and
    finally addding the offset check for nouveau and vc4 they
    already ignore the winsys abstraction.
  - added few more people to Cc which have been touching 
    the files recently.

Tested the patchset on db410c with freedreno driver and compile
tested for the others.

Here we extend dri2 to handle dmabuf plain offsets != 0 applicable
when GStreamer converting YUV->RGB dmabuf buffers using shaders.

regards,
Stan
