Merge tag 'drm-next-2021-09-10' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Dave Airlie: "Just an initial bunch of fixes for the merge window, amdgpu is most of them with a few ttm fixes and an fbdev avoid multiply overflow fix. core: - Make some dma-buf config options depend on DMA_SHARED_BUFFER - Handle multiplication overflow of fbdev xres/yres in the core ttm: - Fix ttm_bo_move_memcpy() when ttm_resource is subclassed - Fix ttm deadlock if target BO isn't idle - ttm build fix - ttm docs fix dma-buf: - config option fixes fbdev: - limit resolutions to avoid int overflow i915: - stddef change. amdgpu: - Misc cleanups, typo fixes - EEPROM fix - Add some new PCI IDs - Scatter/Gather display support for Yellow Carp - PCIe DPM fix for RKL platforms - RAS fix amdkfd: - SVM fix vc4: - static function fix mgag200: - fix uninit var panfrost: - lock_region fixes" * tag 'drm-next-2021-09-10' of git://anongit.freedesktop.org/drm/drm: (36 commits) drm/ttm: Fix a deadlock if the target BO is not idle during swap fbmem: don't allow too huge resolutions dma-buf: DMABUF_SYSFS_STATS should depend on DMA_SHARED_BUFFER dma-buf: DMABUF_DEBUG should depend on DMA_SHARED_BUFFER drm/i915: use linux/stddef.h due to "isystem: trim/fixup stdarg.h and other headers" dma-buf: DMABUF_MOVE_NOTIFY should depend on DMA_SHARED_BUFFER drm/amdkfd: drop process ref count when xnack disable drm/amdgpu: enable more pm sysfs under SRIOV 1-VF mode drm/amdgpu: fix fdinfo race with process exit drm/amdgpu: Fix a deadlock if previous GEM object allocation fails drm/amdgpu: stop scheduler when calling hw_fini (v2) drm/amdgpu: Clear RAS interrupt status on aldebaran drm/amd/display: Initialize lt_settings on instantiation drm/amd/display: cleanup idents after a revert drm/amd/display: Fix memory leak reported by coverity drm/ttm: Fix ttm_bo_move_memcpy() for subclassed struct ttm_resource drm/amdgpu/swsmu: fix spelling mistake "minimun" -> "minimum" drm/amdgpu: Disable PCIE_DPM on Intel RKL Platform drm/amdgpu: show both cmd id and name when psp cmd failed drm/amd/display: setup system context for APUs ...
