[PATCH 00/31] Add GPU scheduler to amdgpu

[Alex Deucher]

This patch set implements a basic GPU scheduler for amdgpu.
A GPU scheduler is required for proper GPU reset and optimal
utilization of hw resources. It's currently disabled by default
as there are a few things we'd like to improve first:
- better integration with kernel fences
- clean up scheduler involvement in the ISR
Enable it with amdgpu.enable_scheduler=1.
Performance is comparable to the non-scheduler paths.

Patches are also available in the drm-next-4.3-wip branch
of my git tree:
