[Mesa-dev] [PATCH 2/7] winsys/amdgpu: don't allow interprocess resource sharing for IBs

[Marek Olšák]

From: Marek Olšák <marek.olsak at amd.com>

Now we should get IB submissions with bo_list == NULL when DRI buffers
aren't referenced.

"Local" BOs are still rather unstable on Raven. Not sure about other GPUs.
