Merge tag 'drm-next-2021-11-12' of git://anongit.freedesktop.org/drm/drm
Pull more drm updates from Dave Airlie: "I missed a drm-misc-next pull for the main pull last week. It wasn't that major and isn't the bulk of this at all. This has a bunch of fixes all over, a lot for amdgpu and i915. bridge: - HPD improvments for lt9611uxc - eDP aux-bus support for ps8640 - LVDS data-mapping selection support ttm: - remove huge page functionality (needs reworking) - fix a race condition during BO eviction panels: - add some new panels fbdev: - fix double-free - remove unused scrolling acceleration - CONFIG_FB dep improvements locking: - improve contended locking logging - naming collision fix dma-buf: - add dma_resv_for_each_fence iterator - fix fence refcounting bug - name locking fixesA prime: - fix object references during mmap nouveau: - various code style changes - refcount fix - device removal fixes - protect client list with a mutex - fix CE0 address calculation i915: - DP rates related fixes - Revert disabling dual eDP that was causing state readout problems - put the cdclk vtables in const data - Fix DVO port type for older platforms - Fix blankscreen by turning DP++ TMDS output buffers on encoder->shutdown - CCS FBs related fixes - Fix recursive lock in GuC submission - Revert guc_id from i915_request tracepoint - Build fix around dmabuf amdgpu: - GPU reset fix - Aldebaran fix - Yellow Carp fixes - DCN2.1 DMCUB fix - IOMMU regression fix for Picasso - DSC display fixes - BPC display calculation fixes - Other misc display fixes - Don't allow partial copy from user for DC debugfs - SRIOV fixes - GFX9 CSB pin count fix - Various IP version check fixes - DP 2.0 fixes - Limit DCN1 MPO fix to DCN1 amdkfd: - SVM fixes - Fix gfx version for renoir - Reset fixes udl: - timeout fix imx: - circular locking fix virtio: - NULL ptr deref fix" * tag 'drm-next-2021-11-12' of git://anongit.freedesktop.org/drm/drm: (126 commits) drm/ttm: Double check mem_type of BO while eviction drm/amdgpu: add missed support for UVD IP_VERSION(3, 0, 64) drm/amdgpu: drop jpeg IP initialization in SRIOV case drm/amd/display: reject both non-zero src_x and src_y only for DCN1x drm/amd/display: Add callbacks for DMUB HPD IRQ notifications drm/amd/display: Don't lock connection_mutex for DMUB HPD drm/amd/display: Add comment where CONFIG_DRM_AMD_DC_DCN macro ends drm/amdkfd: Fix retry fault drain race conditions drm/amdkfd: lower the VAs base offset to 8KB drm/amd/display: fix exit from amdgpu_dm_atomic_check() abruptly drm/amd/amdgpu: fix the kfd pre_reset sequence in sriov drm/amdgpu: fix uvd crash on Polaris12 during driver unloading drm/i915/adlp/fb: Prevent the mapping of redundant trailing padding NULL pages drm/i915/fb: Fix rounding error in subsampled plane size calculation drm/i915/hdmi: Turn DP++ TMDS output buffers back on in encoder->shutdown() drm/locking: fix __stack_depot_* name conflict drm/virtio: Fix NULL dereference error in virtio_gpu_poll drm/amdgpu: fix SI handling in amdgpu_device_asic_has_dc_support() drm/amdgpu: Fix dangling kfd_bo pointer for shared BOs drm/amd/amdkfd: Don't sent command to HWS on kfd reset ...
