Merge tag 'amd-drm-next-6.2-2022-11-18' of https://gitlab.freedesktop.org/agd5f/linux into drm-next
amd-drm-next-6.2-2022-11-18: amdgpu: - SR-IOV fixes - Clean up DC checks - DCN 3.2.x fixes - DCN 3.1.x fixes - Don't enable degamma on asics which don't support it - IP discovery fixes - BACO fixes - Fix vbios allocation handling when vkms is enabled - Drop buggy tdr advanced mode GPU reset handling - Fix the build when DCN is not set in kconfig - MST DSC fixes - Userptr fixes - FRU and RAS EEPROM fixes - VCN 4.x RAS support - Aldrebaran CU occupancy reporting fix - PSP ring cleanup amdkfd: - Memory limit fix - Enable cooperative launch on gfx 10.3 amd-drm-next-6.2-2022-11-11: amdgpu: - SMU 13.x updates - GPUVM TLB race fix - DCN 3.1.4 updates - DCN 3.2.x updates - PSR fixes - Kerneldoc fix - Vega10 fan fix - GPUVM locking fixes in error pathes - BACO fix for Beige Goby - EEPROM I2C address cleanup - GFXOFF fix - Fix DC memory leak in error pathes - Flexible array updates - Mtype fix for GPUVM PTEs - Move Kconfig into amdgpu directory - SR-IOV updates - Fix possible memory leak in CS IOCTL error path amdkfd: - Fix possible memory overrun - CRIU fixes radeon: - ACPI ref count fix - HDA audio notifier support - Move Kconfig into radeon directory UAPI: - Add new GEM_CREATE flags to help to transition more KFD functionality to the DRM UAPI. These are used internally in the driver to align location based memory coherency requirements from memory allocated in the KFD with how we manage GPUVM PTEs. They are currently blocked in the GEM_CREATE IOCTL as we don't have a user right now. They are just used internally in the kernel driver for now for existing KFD memory allocations. So a change to the UAPI header, but no functional change in the UAPI.
