amd-drm-next-5.17-2021-12-02: amdgpu: - Use generic drm fb helpers - PSR fixes - Rework DCN3.1 clkmgr - DPCD 1.3 fixes - Misc display fixes can cleanups - Clock query fixes for APUs - LTTPR fixes - DSC fixes - Misc PM fixes - RAS fixes - OLED backlight fix - SRIOV fixes - Add STB (Smart Trace Buffer) for supported dGPUs - IH rework - Enable seamless boot for DCN3.01 amdkfd: - Rework more stuff around IP discovery enumeration - Further clean up of interfaces with amdgpu - SVM fixes radeon: - Indentation fixes UAPI: - Add a new KFD header that defines some of the sysfs bitfields and enums that userspace has been using for a while The corresponding bit-fields and enums in user mode are defined in https://github.com/RadeonOpenCompute/ROCT-Thunk-Interface/blob/master/include/hsakmttypes.h Signed-off-by: Dave Airlie <airlied@redhat.com> # Conflicts: # drivers/gpu/drm/amd/pm/swsmu/smu_cmn.c From: Alex Deucher <alexander.deucher@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211202191643.5970-1-alexander.deucher@amd.com
