Merge tag 'drm-next-2024-11-21' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie: "There's a lot of rework, the panic helper support is being added to more drivers, v3d gets support for HW superpages, scheduler documentation, drm client and video aperture reworks, some new MAINTAINERS added, amdgpu has the usual lots of IP refactors, Intel has some Pantherlake enablement and xe is getting some SRIOV bits, but just lots of stuff everywhere. core: - split DSC helpers from DP helpers - clang build fixes for drm/mm test - drop simple pipeline support for gem vram - document submission error signaling - move drm_rect to drm core module from kms helper - add default client setup to most drivers - move to video aperture helpers instead of drm ones tests: - new framebuffer tests ttm: - remove swapped and pinned BOs from TTM lru panic: - fix uninit spinlock - add ABGR2101010 support bridge: - add TI TDP158 support - use standard PM OPS dma-fence: - use read_trylock instead of read_lock to help lockdep scheduler: - add errno to sched start to report different errors - add locking to drm_sched_entity_modify_sched - improve documentation xe: - add drm_line_printer - lots of refactoring - Enable Xe2 + PES disaggregation - add new ARL PCI ID - SRIOV development work - fix exec unnecessary implicit fence - define and parse OA sync props - forcewake refactoring i915: - Enable BMG/LNL ultra joiner - Enable 10bpx + CCS scanout on ICL+, fp16/CCS on TGL+ - use DSB for plane/color mgmt - Arrow lake PCI IDs - lots of i915/xe display refactoring - enable PXP GuC autoteardown - Pantherlake (PTL) Xe3 LPD display enablement - Allow fastset HDR infoframe changes - write DP source OUI for non-eDP sinks - share PCI IDs between i915 and xe amdgpu: - SDMA queue reset support - SMU 13.0.6, JPEG 4.0.3 updates - Initial runtime repartitioning support - rework IP structs for multiple IP instances - Fetch EDID from _DDC if available - SMU13 zero rpm user control - lots of fixes/cleanups amdkfd: - Increase event FIFO size - add topology cap flag for per queue reset msm: - DPU: - SA8775P support - (disabled by default) MSM8917, MSM8937, MSM8953 and MSM8996 support - Enable large framebuffer support - Drop MSM8998 and SDM845 - DP: - SA8775P support - GPU: - a7xx preemption support - Adreno A663 support ast: - warn about unsupported TX chips ivpu: - add coredump - add pantherlake support rockchip: - 4K@60Hz display enablement - generate pll programming tables panthor: - add timestamp query API - add realtime group priority - add fdinfo support etnaviv: - improve handling of DMA address limits - improve GPU hangcheck exynos: - Decon Exynos7870 support mediatek: - add OF graph support omap: - locking fixes bochs: - convert to gem/shmem from simpledrm v3d: - support big/super pages - add gemfs vc4: - BCM2712 support refactoring - add YUV444 format support udmabuf: - folio related fixes nouveau: - add panic support on nv50+" * tag 'drm-next-2024-11-21' of https://gitlab.freedesktop.org/drm/kernel: (1583 commits) drm/xe/guc: Fix dereference before NULL check drm/amd: Fix initialization mistake for NBIO 7.7.0 Revert "drm/amd/display: parse umc_info or vram_info based on ASIC" drm/amd/display: Fix failure to read vram info due to static BP_RESULT drm/amdgpu: enable GTT fallback handling for dGPUs only drm/amd/amdgpu: limit single process inside MES drm/fourcc: add AMD_FMT_MOD_TILE_GFX9_4K_D_X drm/amdgpu/mes12: correct kiq unmap latency drm/amdgpu: Support vcn and jpeg error info parsing drm/amd : Update MES API header file for v11 & v12 drm/amd/amdkfd: add/remove kfd queues on start/stop KFD scheduling drm/amdkfd: change kfd process kref count at creation drm/amdgpu: Cleanup shift coding style drm/amd/amdgpu: Increase MES log buffer to dump mes scratch data drm/amdgpu: Implement virt req_ras_err_count drm/amdgpu: VF Query RAS Caps from Host if supported drm/amdgpu: Add msg handlers for SRIOV RAS Telemetry drm/amdgpu: Update SRIOV Exchange Headers for RAS Telemetry Support drm/amd/display: 3.2.309 drm/amd/display: Adjust VSDB parser for replay feature ...
