Merge tag 'drm-next-2023-04-24' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie: "There is a new Qualcomm accel driver for their QAIC, dma-fence got a deadline feature added, lots of refactoring around fbdev emulation, and the usual pre-release hw enablements from AMD and Intel and fixes everywhere. New drivers: - add QAIC acceleration driver dma-buf: - constify kobj_type structs - Reject prime DMA-Buf attachment if get_sg_table is missing. fbdev: - cmdline parser fixes - implement fbdev emulation for GEM DMA drivers - always use shadow buffer in fbdev emulation helpers dma-fence: - add deadline hint to fences - signal private stub fence core: - improve DisplayID 2.0 and EDID parsing - add gem eviction function + callback - prep to convert shmem helper to GEM resv lock - move suballocator from radeon/amdgpu to core for Xe - HPD polling fixes - Documentation improvements - Add atomic enable_plane callback - use tgid instead of pid for client tracking - DP: Add SDP Error Detection Configuration Register - Add prime import/export to vram-helper - use pci aperture helpers in more drivers panel: - Radxa 8/10HD support - Samsung AMD495QA01 support - Elida KD50T048A - Sony TD4353 - Novatek NT36523 - STARRY 2081101QFH032011-53G - B133UAN01.0 - AUO NE135FBM-N41 i915: - More MTL enabling - fix s/r problems with MEI/PXP - Implement fb_dirty for PSR,FBC,DRRS fixes - Fix eDP+DSI dual panel systems - Fix issue #6333: "list_add corruption" and full system lockup from performance monitoring - Don't use stolen memory or BAR for ring buffers on LLC platforms - Make sure DSM size has correct 1MiB granularity on Gen12+ - Whitelist COMMON_SLICE_CHICKEN3 for UMD access on Gen12+ - Add engine TLB invalidation for Meteorlake - Fix GSC races on driver load/unload on Meteorlake+ - Make kobj_type structures constant - Move fd_install after last use of fence - wm/vblank refactoring - display code refactoring - Create GSC submission targeting HDCP and PXP usages on MTL+ - Enable HDCP2.x via GSC CS - Fix context runtime accounting on sysfs fdinfo for heavy workloads - Use i915 instead of dev_priv insied the file_priv structure - Replace fake flex-array with flexible-array member amdgpu: - Make kobj structures const - Generalize dmabuf import to work with KFD - Add capped/uncapped workload handling for supported APUs - Expose additional memory stats via fdinfo - Register vga_switcheroo for apple-gmux - Initial NBIO7.9, GC 9.4.3, GFXHUB 1.2, MMHUB 1.8 support - Initial DC FAM infrastructure - Link DC backlight to connector device rather than PCI device - Add sysfs nodes for secondary VCN clocks amdkfd: - Make kobj structures const - Support for exporting buffers via dmabuf - Multi-VMA page migration fixes - initial GC 9.4.3 support radeon: - iMac fix - convert to client based fbdev emulation habanalabs: - Add opcodes to the CS ioctl to allow user to stall/resume specific engines inside Gaudi2. - INFO ioctl the amount of device memory that the driver and f/w reserve for themselves. - INFO ioctl a bit-mask of the available rotator engines - INFO ioctl the register's address of the f/w that should be used to trigger interrupts - INFO ioctl two new opcodes to fetch information on h/w and f/w events - Enable graceful reset mechanism for compute-reset. - Align to the latest firmware specs. - Enforce the release order of the compute device and dma-buf. msm: - UBWC decoder programming rework - SM8550, SM8450 bindings update - uapi C++ fix - a3xx and a4xx devfreq support - GPU and GEM updates to avoid allocations which could trigger reclaim (shrinker) in fence signaling path - dma-fence deadline hint support and wait-boost - a640/650 speed bin support cirrus: - convert to regular atomic helpers - add damage clipping mediatek: - 10-bit overlay support - mt8195 support - Only trigger DRM HPD events if bridge is attached - Change the aux retries times when receiving AUX_DEFER rockchip: - add 4K support vc4: - use drm_gem_objects virtio: - allow KMS support to be disabled - add damage clipping vmwgfx: - buffer object lifetime fixes exynos: - move MIPI DSI driver to drm bridge for iMX sharing -
