Merge branch 'drm-next-4.21' of git://people.freedesktop.org/~agd5f/linux into drm-next
New features for 4.21: amdgpu: - Support for SDMA paging queue on vega - Put compute EOP buffers into vram for better performance - Share more code with amdkfd - Support for scanout with DCC on gfx9 - Initial kerneldoc for DC - Updated SMU firmware support for gfx8 chips - Rework CSA handling for eventual support for preemption - XGMI PSP support - Clean up RLC handling - Enable GPU reset by default on VI, SOC15 dGPUs - Ring and IB test cleanups amdkfd: - Share more code with amdgpu ttm: - Move global init out of the drivers scheduler: - Track if schedulers are ready for work - Timeout/fault handling changes to facilitate GPU recovery Signed-off-by: Dave Airlie <airlied@redhat.com> From: Alex Deucher <alexdeucher@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181114165113.3751-1-alexander.deucher@amd.com
