drm-next-5.5-2019-10-09: amdgpu: - Additional RAS enablement for vega20 - RAS page retirement and bad page storage in EEPROM - No GPU reset with unrecoverable RAS errors - Reserve vram for page tables rather than trying to evict - Fix issues with GPU reset and xgmi hives - DC i2c over aux fixes - Direct submission for clears, PTE/PDE updates - Improvements to help support recoverable GPU page faults - Silence harmless SAD block messages - Clean up code for creating a bo at a fixed location - Initial DC HDCP support - Lots of documentation fixes - GPU reset for renoir - Add IH clockgating support for soc15 asics - Powerplay improvements - DC MST cleanups - Add support for MSI-X - Misc cleanups and bug fixes amdkfd: - Query KFD device info by asic type rather than pci ids - Add navi14 support - Add renoir support - Add navi12 support - gfx10 trap handler improvements - pasid cleanups - Check against device cgroup ttm: - Return -EBUSY with pipelining with no_gpu_wait radeon: - Silence harmless SAD block messages device_cgroup: - Export devcgroup_check_permission Signed-off-by: Dave Airlie <airlied@redhat.com> From: Alex Deucher <alexdeucher@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191010041713.3412-1-alexander.deucher@amd.com
