amd-drm-next-5.14-2021-06-02: amdgpu: - GC/MM register access macro clean up for SR-IOV - Beige Goby updates - W=1 Fixes - Aldebaran fixes - Misc display fixes - ACPI ATCS/ATIF handling rework - SR-IOV fixes - RAS fixes - 16bpc fixed point format support - Initial smartshift support - RV/PCO power tuning fixes for suspend/resume - More buffer object subclassing work - Add new INFO query for additional vbios information - Add new placement for preemptable SG buffers amdkfd: - Misc fixes radeon: - W=1 Fixes - Misc cleanups UAPI: - Add new INFO query for additional vbios information Useful for debugging vbios related issues. Proposed umr patch: https://patchwork.freedesktop.org/patch/433297/ - 16bpc fixed point format support IGT test: https://lists.freedesktop.org/archives/igt-dev/2021-May/031507.html Proposed Vulkan patch: a25d480207 - Add a new GEM flag which is only used internally in the kernel driver. Userspace is not allowed to set it. drm: - 16bpc fixed point format fourcc Signed-off-by: Dave Airlie <airlied@redhat.com> From: Alex Deucher <alexander.deucher@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210602214009.4553-1-alexander.deucher@amd.com
