Merge tag 'drm-next-2025-07-30' of https://gitlab.freedesktop.org/drm/kernelHEADmaster
Pull drm updates from Dave Airlie: "Highlights: - Intel xe enable Panthor Lake, started adding WildCat Lake - amdgpu has a bunch of reset improvments along with the usual IP updates - msm got VM_BIND support which is important for vulkan sparse memory - more drm_panic users - gpusvm common code to handle a bunch of core SVM work outside drivers. Detail summary: Changes outside drm subdirectory: - 'shrink_shmem_memory()' for better shmem/hibernate interaction - Rust support infrastructure: - make ETIMEDOUT available - add size constants up to SZ_2G - add DMA coherent allocation bindings - mtd driver for Intel GPU non-volatile storage - i2c designware quirk for Intel xe core: - atomic helpers: tune enable/disable sequences - add task info to wedge API - refactor EDID quirks - connector: move HDR sink to drm_display_info - fourcc: half-float and 32-bit float formats - mode_config: pass format info to simplify dma-buf: - heaps: Give CMA heap a stable name ci: - add device tree validation and kunit displayport: - change AUX DPCD access probe address - add quirk for DPCD probe - add panel replay definitions - backlight control helpers fbdev: - make CONFIG_FIRMWARE_EDID available on all arches fence: - fix UAF issues format-helper: - improve tests gpusvm: - introduce devmem only flag for allocation - add timeslicing support to GPU SVM ttm: - improve eviction sched: - tracing improvements - kunit improvements - memory leak fixes - reset handling improvements color mgmt: - add hardware gamma LUT handling helpers bridge: - add destroy hook - switch to reference counted drm_bridge allocations - tc358767: convert to devm_drm_bridge_alloc - improve CEC handling panel: - switch to reference counter drm_panel allocations - fwnode panel lookup - Huiling hl055fhv028c support - Raspberry Pi 7" 720x1280 support - edp: KDC KD116N3730A05, N160JCE-ELL CMN, N116BCJ-EAK - simple: AUO P238HAN01 - st7701: Winstar wf40eswaa6mnn0 - visionox: rm69299-shift - Renesas R61307, Renesas R69328 support - DJN HX83112B hdmi: - add CEC handling - YUV420 output support xe: - WildCat Lake support - Enable PanthorLake by default - mark BMG as SRIOV capable - update firmware recommendations - Expose media OA units - aux-bux support for non-volatile memory - MTD intel-dg driver for non-volatile memory - Expose fan control and voltage regulator in sysfs - restructure migration for multi-device - Restore GuC submit UAF fix - make GEM shrinker drm managed - SRIOV VF Post-migration recovery of GGTT nodes - W/A additions/reworks - Prefetch support for svm ranges - Don't allocate managed BO for each policy change - HWMON fixes for BMG - Create LRC BO without VM - PCI ID updates - make SLPC debugfs files optional - rework eviction rejection of bound external BOs - consolidate PAT programming logic for pre/post Xe2 - init changes for flicker-free boot - Enable GuC Dynamic Inhibit Context switch i915: - drm_panic support for i915/xe - initial flip queue off by default for LNL/PNL - Wildcat Lake Display support - Support for DSC fractional link bpp - Support for simultaneous Panel Replay and Adaptive sync - Support for PTL+ double buffer LUT - initial PIPEDMC event handling - drm_panel_follower support - DPLL interface renames - allocate struct intel_display dynamically - flip queue preperation - abstract DRAM detection better - avoid GuC scheduling stalls - remove DG1 force probe requirement - fix MEI interrupt handler on RT kernels - use backlight control helpers for eDP - more shared display code refactoring amdgpu: - add userq slot to INFO ioctl - SR-IOV hibernation support - Suspend improvements - Backlight improvements - Use scaling for non-native eDP modes - cleaner shader updates for GC 9.x - Remove fence slab - SDMA fw checks for userq support - RAS updates - DMCUB updates - DP tunneling fixes - Display idle D3 support - Per queue reset improvements - initial smartmux support amdkfd: - enable KFD on loongarch - mtype fix for ext coherent system memory radeon: - CS validation additional GL extensions - drop console lock during suspend/resume - bump driver version msm: - VM BIND support - CI: infrastructure updates - UBWC single source of truth - decouple GPU and KMS support - DP: rework I/O accessors - DPU: SM8750 support - DSI: SM8750 support - GPU: X1-45 support and speedbin support for X1-85 - MDSS: SM8750 support nova: - register!
