Pull drm updates from Dave Airlie: "There are two external interactions of note, the msm tree pull in some opp tree, hopefully the opp tree arrives from the same git tree however it normally does. There is also a new cgroup controller for device memory, that is used by drm, so is merging through my tree. This will hopefully help open up gpu cgroup usage a bit more and move us forward. There is a new accelerator driver for the AMD XDNA Ryzen AI NPUs. Then the usual xe/amdgpu/i915/msm leaders and lots of changes and refactors across the board: core: - device memory cgroup controller added - Remove driver date from drm_driver - Add drm_printer based hex dumper - drm memory stats docs update - scheduler documentation improvements new driver: - amdxdna - Ryzen AI NPU support connector: - add a mutex to protect ELD - make connector setup two-step panels: - Introduce backlight quirks infrastructure - New panels: KDB KD116N2130B12, Tianma TM070JDHG34-00, - Multi-Inno Technology MI1010Z1T-1CP11 bridge: - ti-sn65dsi83: Add ti,lvds-vod-swing optional properties - Provide default implementation of atomic_check for HDMI bridges - it605: HDCP improvements, MCCS Support xe: - make OA buffer size configurable - GuC capture fixes - add ufence and g2h flushes - restore system memory GGTT mappings - ioctl fixes - SRIOV PF scheduling priority - allow fault injection - lots of improvements/refactors - Enable GuC's WA_DUAL_QUEUE for newer platforms - IRQ related fixes and improvements i915: - More accurate engine busyness metrics with GuC submission - Ensure partial BO segment offset never exceeds allowed max - Flush GuC CT receive tasklet during reset preparation - Some DG2 refactor to fix DG2 bugs when operating with certain CPUs - Fix DG1 power gate sequence - Enabling uncompressed 128b/132b UHBR SST - Handle hdmi connector init failures, and no HDMI/DP cases - More robust engine resets on Haswell and older i915/xe display: - HDCP fixes for Xe3Lpd - New GSC FW ARL-H/ARL-U - support 3 VDSC engines 12 slices - MBUS joining sanitisation - reconcile i915/xe display power mgmt - Xe3Lpd fixes - UHBR rates for Thunderbolt amdgpu: - DRM panic support - track BO memory stats at runtime - Fix max surface handling in DC - Cleaner shader support for gfx10.3 dGPUs - fix drm buddy trim handling - SDMA engine reset updates - Fix doorbell ttm cleanup - RAS updates - ISP updates - SDMA queue reset support - Rework DPM powergating interfaces - Documentation updates and cleanups - DCN 3.5 updates - Use a pm notifier to more gracefully handle VRAM eviction on suspend or hibernate - Add debugfs interfaces for forcing scheduling to specific engine instances - GG 9.5 updates - IH 4.4 updates - Make missing optional firmware less noisy - PSP 13.x updates - SMU 13.x updates - VCN 5.x updates - JPEG 5.x updates - GC 12.x updates - DC FAMS updates amdkfd: - GG 9.5 updates - Logging improvements - Shader debugger fixes - Trap handler cleanup - Cleanup includes - Eviction fence wq fix msm: - MDSS: - properly described UBWC registers - added SM6150 (aka QCS615) support - DPU: - added SM6150 (aka QCS615) support - enabled wide planes if virtual planes are enabled (by using two SSPPs for a single plane) - added CWB hardware blocks support - DSI: - added SM6150 (aka QCS615) support - GPU: - Print GMU core fw version - GMU bandwidth voting for a740 and a750 - Expose uche trap base via uapi - UAPI error reporting rcar-du: - Add r8a779h0 Support ivpu: - Fix qemu crash when using passthrough nouveau: - expose GSP-RM logging buffers via debugfs panfrost: - Add MT8188 Mali-G57 MC3 support rockchip: - Gamma LUT support hisilicon: - new HIBMC support virtio-gpu: - convert to helpers - add prime support for scanout buffers v3d: - Add DRM_IOCTL_V3D_PERFMON_SET_GLOBAL vc4: - Add support for BCM2712 vkms: - line-per-line compositing algorithm to improve performance zynqmp: - Add DP audio support mediatek: - dp: Add sdp path reset - dp: Support flexible length of DP calibration data etnaviv: - add fdinfo memory support - add explicit reset handling" * tag 'drm-next-2025-01-17' of https://gitlab.freedesktop.org/drm/kernel: (1070 commits) drm/bridge: fix documentation for the hdmi_audio_prepare() callback doc/cgroup: Fix title underline length drm/doc: Include new drm-compute documentation cgroup/dmem: Fix parameters documentation cgroup/dmem: Select PAGE_COUNTER kernel/cgroup: Remove the unused variable climit drm/display: hdmi: Do not read EDID on disconnected connectors drm/tests: hdmi: Add connector disablement test drm/connector: hdmi: Do atomic check when necessary drm/amd/display: 3.2.316 drm/amd/display: avoid reset DTBCLK at clock init drm/amd/display: improve dpia pre-train drm/amd/display: Apply DML21 Patches drm/amd/display: Use HW lock mgr for PSR1 drm/amd/display: Revised for Replay Pseudo vblank control drm/amd/display: Add a new flag for replay low hz drm/amd/display: Remove unused read_ono_state function from Hwss module drm/amd/display: Do not elevate mem_type change to full update drm/amd/display: Do not wait for PSR disable on vbl enable drm/amd/display: Remove unnecessary eDP power down ...
