Merge tag 'drm-for-v4.15' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "This is the main drm pull request for v4.15. Core: - Atomic object lifetime fixes - Atomic iterator improvements - Sparse/smatch fixes - Legacy kms ioctls to be interruptible - EDID override improvements - fb/gem helper cleanups - Simple outreachy patches - Documentation improvements - Fix dma-buf rcu races - DRM mode object leasing for improving VR use cases. - vgaarb improvements for non-x86 platforms. New driver: - tve200: Faraday Technology TVE200 block. This "TV Encoder" encodes a ITU-T BT.656 stream and can be found in the StorLink SL3516 (later Cortina Systems CS3516) as well as the Grain Media GM8180. New bridges: - SiI9234 support New panels: - S6E63J0X03, OTM8009A, Seiko 43WVF1G, 7" rpi touch panel, Toshiba LT089AC19000, Innolux AT043TN24 i915: - Remove Coffeelake from alpha support - Cannonlake workarounds - Infoframe refactoring for DisplayPort - VBT updates - DisplayPort vswing/emph/buffer translation refactoring - CCS fixes - Restore GPU clock boost on missed vblanks - Scatter list updates for userptr allocations - Gen9+ transition watermarks - Display IPC (Isochronous Priority Control) - Private PAT management - GVT: improved error handling and pci config sanitizing - Execlist refactoring - Transparent Huge Page support - User defined priorities support - HuC/GuC firmware refactoring - DP MST fixes - eDP power sequencing fixes - Use RCU instead of stop_machine - PSR state tracking support - Eviction fixes - BDW DP aux channel timeout fixes - LSPCON fixes - Cannonlake PLL fixes amdgpu: - Per VM BO support - Powerplay cleanups - CI powerplay support - PASID mgr for kfd - SR-IOV fixes - initial GPU reset for vega10 - Prime mmap support - TTM updates - Clock query interface for Raven - Fence to handle ioctl - UVD encode ring support on Polaris - Transparent huge page DMA support - Compute LRU pipe tweaks - BO flag to allow buffers to opt out of implicit sync - CTX priority setting API - VRAM lost infrastructure plumbing qxl: - fix flicker since atomic rework amdkfd: - Further improvements from internal AMD tree - Usermode events - Drop radeon support nouveau: - Pascal temperature sensor support - Improved BAR2 handling - MMU rework to support Pascal MMU exynos: - Improved HDMI/mixer support - HDMI audio interface support tegra: - Prep work for tegra186 - Cleanup/fixes msm: - Preemption support for a5xx - Display fixes for 8x96 (snapdragon 820) - Async cursor plane fixes - FW loading rework - GPU debugging improvements vc4: - Prep for DSI panels - fix T-format tiling scanout - New madvise ioctl Rockchip: - LVDS support omapdrm: - omap4 HDMI CEC support etnaviv: - GPU performance counters groundwork sun4i: - refactor driver load + TCON backend - HDMI improvements - A31 support - Misc fixes udl: - Probe/EDID read fixes. tilcdc: - Misc fixes. pl111: - Support more variants adv7511: - Improve EDID handling. - HDMI CEC support sii8620: - Add remote control support" * tag 'drm-for-v4.15' of git://people.freedesktop.org/~airlied/linux: (1480 commits) drm/rockchip: analogix_dp: Use mutex rather than spinlock drm/mode_object: fix documentation for object lookups. drm/i915: Reorder context-close to avoid calling i915_vma_close() under RCU drm/i915: Move init_clock_gating() back to where it was drm/i915: Prune the reservation shared fence array drm/i915: Idle the GPU before shinking everything drm/i915: Lock llist_del_first() vs llist_del_all() drm/i915: Calculate ironlake intermediate watermarks correctly, v2. drm/i915: Disable lazy PPGTT page table optimization for vGPU drm/i915/execlists: Remove the priority "optimisation" drm/i915: Filter out spurious execlists context-switch interrupts drm/amdgpu: use irq-safe lock for kiq->ring_lock drm/amdgpu: bypass lru touch for KIQ ring submission drm/amdgpu: Potential uninitialized variable in amdgpu_vm_update_directories() drm/amdgpu: potential uninitialized variable in amdgpu_vce_ring_parse_cs() drm/amd/powerplay: initialize a variable before using it drm/amd/powerplay: suppress KASAN out of bounds warning in vega10_populate_all_memory_levels drm/amd/amdgpu: fix evicted VRAM bo adjudgement condition drm/vblank: Tune drm_crtc_accurate_vblank_count() WARN down to a debug drm/rockchip: add CONFIG_OF dependency for lvds ...
