Pull drm updates from Dave Airlie: "Highlights: - i915 has seen a lot of refactoring and uAPI cleanups due to a change in the upstream direction going forward This has all been audited with known userspace, but there may be some pitfalls that were missed. - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs - i915 enables Jasper and Elkhart Lake by default and has preliminary XeHP/DG2 support - amdgpu adds support for Cyan Skillfish - lots of implicit fencing rules documented and fixed up in drivers - msm now uses the core scheduler - the irq midlayer has been removed for non-legacy drivers - the sysfb code now works on more than x86. Otherwise the usual smattering of stuff everywhere, panels, bridges, refactorings. Detailed summary: core: - extract i915 eDP backlight into core - DP aux bus support - drm_device.irq_enabled removed - port drivers to native irq interfaces - export gem shadow plane handling for vgem - print proper driver name in framebuffer registration - driver fixes for implicit fencing rules - ARM fixed rate compression modifier added - updated fb damage handling - rmfb ioctl logging/docs - drop drm_gem_object_put_locked - define DRM_FORMAT_MAX_PLANES - add gem fb vmap/vunmap helpers - add lockdep_assert(once) helpers - mark drm irq midlayer as legacy - use offset adjusted bo mapping conversion vgaarb: - cleanups fbdev: - extend efifb handling to all arches - div by 0 fixes for multiple drivers udmabuf: - add hugepage mapping support dma-buf: - non-dynamic exporter fixups - document implicit fencing rules amdgpu: - Initial Cyan Skillfish support - switch virtual DCE over to vkms based atomic - VCN/JPEG power down fixes - NAVI PCIE link handling fixes - AMD HDMI freesync fixes - Yellow Carp + Beige Goby fixes - Clockgating/S0ix/SMU/EEPROM fixes - embed hw fence in job - rework dma-resv handling - ensure eviction to system ram amdkfd: - uapi: SVM address range query added - sysfs leak fix - GPUVM TLB optimizations - vmfault/migration counters i915: - Enable JSL and EHL by default - preliminary XeHP/DG2 support - remove all CNL support (never shipped) - move to TTM for discrete memory support - allow mixed object mmap handling - GEM uAPI spring cleaning - add I915_MMAP_OBJECT_FIXED - reinstate ADL-P mmap ioctls - drop a bunch of unused by userspace features - disable and remove GPU relocations - revert some i915 misfeatures - major refactoring of GuC for Gen11+ - execbuffer object locking separate step - reject caching/set-domain on discrete - Enable pipe DMC loading on XE-LPD and ADL-P - add PSF GV point support - Refactor and fix DDI buffer translations - Clean up FBC CFB allocation code - Finish INTEL_GEN() and friends macro conversions nouveau: - add eDP backlight support - implicit fence fix msm: - a680/7c3 support - drm/scheduler conversion panfrost: - rework GPU reset virtio: - fix fencing for planes ast: - add detect support bochs: - move to tiny GPU driver vc4: - use hotplug irqs - HDMI codec support vmwgfx: - use internal vmware device headers ingenic: - demidlayering irq rcar-du: - shutdown fixes - convert to bridge connector helpers zynqmp-dsub: - misc fixes mgag200: - convert PLL handling to atomic mediatek: - MT8133 AAL support - gem mmap object support - MT8167 support etnaviv: - NXP Layerscape LS1028A SoC support - GEM mmap cleanups tegra: - new user API exynos: - missing unlock fix - build warning fix - use refcount_t" * tag 'drm-next-2021-08-31-1' of git://anongit.freedesktop.org/drm/drm: (1318 commits) drm/amd/display: Move AllowDRAMSelfRefreshOrDRAMClockChangeInVblank to bounding box drm/amd/display: Remove duplicate dml init drm/amd/display: Update bounding box states (v2) drm/amd/display: Update number of DCN3 clock states drm/amdgpu: disable GFX CGCG in aldebaran drm/amdgpu: Clear RAS interrupt status on aldebaran drm/amdgpu: Add support for RAS XGMI err query drm/amdkfd: Account for SH/SE count when setting up cu masks. drm/amdgpu: rename amdgpu_bo_get_preferred_pin_domain drm/amdgpu: drop redundant cancel_delayed_work_sync call drm/amdgpu: add missing cleanups for more ASICs on UVD/VCE suspend drm/amdgpu: add missing cleanups for Polaris12 UVD/VCE on suspend drm/amdkfd: map SVM range with correct access permission drm/amdkfd: check access permisson to restore retry fault drm/amdgpu: Update RAS XGMI Error Query drm/amdgpu: Add driver infrastructure for MCA RAS drm/amd/display: Add Logging for HDMI color depth information drm/amd/amdgpu: consolidate PSP TA init shared buf functions drm/amd/amdgpu: add name field back to ras_common_if drm/amdgpu: Fix build with missing pm_suspend_target_state module export ...
