Merge branch 'drm-next-4.8' of git://people.freedesktop.org/~agd5f/linux into drm-next
This is the main 4.8 pull for radeon and amdgpu. Sorry for the delay, I meant to send this out last week, but I was moving house. Lots of changes here: - ATPX improvements for better dGPU power control on PX systems - New power features for CZ/BR/ST - Pipelined BO moves and evictions in TTM - GPU scheduler improvements - GPU reset improvements - Overclocking on dGPUs with amdgpu - Lots of code cleanup - Bug fixes * 'drm-next-4.8' of git://people.freedesktop.org/~agd5f/linux: (191 commits) drm/amd/powerplay: don't add invalid voltage. drm/amdgpu: add read/write function for GC CAC programming drm/amd/powerplay: add definitions related to di/dt feature for fiji and polaris. drm/amd/powerplay: add shared definitions for di/dt feature. drm/amdgpu: remove gfx8 registers that vary between asics drm/amd/powerplay: add mvdd dpm support. drm/amdgpu: get number of shade engine by cgs interface. drm/amdgpu: remove more of the ring backup code drm/amd/powerplay: Unify family defines drm/amdgpu: clean up ring_backup code, no need more drm/amdgpu: ib test first after gpu reset drm/amdgpu: recovery hw jobs when gpu reset V3 drm/amdgpu: abstract amdgpu_vm_is_gpu_reset drm/amdgpu: add a bool to specify if needing vm flush V2 drm/amdgpu: add amd_sched_job_recovery drm/amdgpu: force completion for gpu reset drm/amdgpu: block ttm first before parking scheduler drm/amd: add amd_sched_hw_job_reset drm/amd: add parent for sched fence drm/amdgpu: remove evict vram ...
