            Bug ID: 102296
           Summary: R9 285 VCE corruption since drm/amdgpu/gmc8: use the
                    vram location programmed by the vbios
           Product: DRI
           Version: DRI git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: adf.lists@gmail.com

Bit late with this, bisected on drm-next-4.13-wip

R9 285 Tonga I am getting corrupted output from VCE encode, omx or vaapi since
below commit.

To re-produce this you need to use gstreamer and encode "fast and large" eg.
2160p from raw nv12.

Slow things like ffmpeg or gst-vaapi without ! queue ! seem to hide the issue
somewhat.

    drm/amdgpu/gmc8: use the vram location programmed by the vbios

    This makes mc programming much simpler in future patches.

    Since evergreen, the vbios has been programming the fb location
    to the proper vram size.  The only reason to reprogram it would
    be to change the location.
