Merge tag 'drm-next-2022-01-07' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie: "Highlights are support for privacy screens found in new laptops, a bunch of nomodeset refactoring, and i915 enables ADL-P systems by default, while starting to add RPL-S support. vmwgfx adds GEM and support for OpenGL 4.3 features in userspace. Lots of internal refactorings around dma reservations, and lots of driver refactoring as well. Summary: core: - add privacy screen support - move nomodeset option into drm subsystem - clean up nomodeset handling in drivers - make drm_irq.c legacy - fix stack_depot name conflicts - remove DMA_BUF_SET_NAME ioctl restrictions - sysfs: send hotplug event - replace several DRM_* logging macros with drm_* - move hashtable to legacy code - add error return from gem_create_object - cma-helper: improve interfaces, drop CONFIG_DRM_KMS_CMA_HELPER - kernel.h related include cleanups - support XRGB2101010 source buffers ttm: - don't include drm hashtable - stop pruning fences after wait - documentation updates dma-buf: - add dma_resv selftest - add debugfs helpers - remove dma_resv_get_excl_unlocked - documentation - make fences mandatory in dma_resv_add_excl_fence dp: - add link training delay helpers gem: - link shmem/cma helpers into separate modules - use dma_resv iteratior -

add bunch of new panesl simpledrm: - support FB_DAMAGE_CLIPS - support virtual screen sizes - add Apple M1 support amdgpu: - enable seamless boot for DCN 3.01 - runtime PM fixes - use drm_kms_helper_connector_hotplug_event - get all fences at once - use generic drm fb helpers - PSR/DPCD/LTTPR/DSC/PM/RAS/OLED/SRIOV fixes - add smart trace buffer (STB) for supported GPUs - display debugfs entries - new SMU debug option - Documentation update amdkfd: - IP discovery enumeration refactor - interface between driver fixes - SVM fixes - kfd uapi header to define some sysfs bitfields. i915: - support VESA panel backlights - enable ADL-P by default - add eDP privacy screen support - add Raptor Lake S (RPL-S) support - DG2 page table support - lots of GuC/HuC fw refactoring - refactored i915->gt interfaces - CD clock squashing support - enable 10-bit gamma support - update ADL-P DMC fw to v2.14 - enable runtime PM autosuspend by default - ADL-P DSI support - per-lane DP drive settings for ICL+ - add support for pipe C/D DMC firmware - Atomic gamma LUT updates - remove CCS FB stride restrictions on ADL-P - VRR platform support for display 11 - add support for display audio codec keepalive - lots of display refactoring - fix runtime PM handling during PXP suspend - improved eviction performance with async TTM moves - async VMA unbinding improvements - VMA locking refactoring - improved error capture robustness - use per device iommu checks - drop bits stealing from i915_sw_fence function ptr - remove dma_resv_prune -
