Merge tag 'drm-next-2019-03-06' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie: "This is the main drm pull request for the 5.1 merge window. The big changes I'd highlight are: - nouveau has HMM support now, there is finally an in-tree user so we can quieten down the rip it out people. - i915 now enables fastboot by default on Skylake+ - Displayport Multistream support has been refactored and should hopefully be more reliable. Core: - header cleanups aiming towards removing drmP.h - dma-buf fence seqnos to 64-bits - common helper for DP mst hotplug for radeon,i915,amdgpu + new refcounting scheme - MST i2c improvements - drm_syncobj_cb removal - ARM FB compression fourcc - P010 + P016 fourcc - allwinner tiled format modifier - i2c over aux I2C_M_STOP support - DRM_AUTH handling fixes TTM: - ref/unref renaming New driver: - ARM komeda display driver scheduler: - refactor mirror list handling - rework hw fence processing - 0 run queue entity fix bridge: - TI DS90C185 LVDS bridge - thc631lvdm83d bridge improvements - cadence + allwinner DSI ported to generic phy panels: - Sitronix ST7701 panel - Kingdisplay KD097D04 - LeMaker BL035-RGB-002 - PDA 91-00156-A0 - Innolux EE101IA-01D i915: - Enable fastboot by default on SKL+/VLV/CHV - Export RPCS configuration for ICL media driver - Coffelake PCI ID - CNL clocks setup fixes - ACPI/PMIC support for MIPI/DSI - Per-engine WA init for all engines - Shrinker locking fixes - Kerneldoc updates - Lots of ring improvements and reset fixes - Coffeelake GVT Support - VFIO GVT EDID Region support - runtime PM wakeref tracking - ILK->IVB primary plane enable delays - userptr mutex locking fixes - DSI fixes - LVDS/TV cleanups - HW readout fixes - LUT robustness fixes - ICL display and watermark fixes - gem mmap race fix amdgpu: - add scheduled dependencies interface - DCC on scanout surfaces - vega10/20 BACO support - Multiple IH rings on soc15 - XGMI locking fixes - DC i2c/aux cleanups - runtime SMU debug interface - Kexec improvmeents - SR-IOV fixes - DC freesync + ABM fixes - GDS fixes - GPUVM fixes - vega20 PCIE DPM switching fixes - Context priority handling fixes radeon: - fix missing break in evergreen parser nouveau: - SVM support via HMM msm: - QCOM Compressed modifier support exynos: - s5pv210 rotator support imx: - zpos property support - pending update fixes v3d: - cache flush improvments vc4: - reflection support - HDMI overscan support tegra: - CEC refactoring - HDMI audio fixes - Tegra186 prep work - SOR crossbar device tree fixes sun4i: - implicit fencing support - YUV and scalar support improvements - A23 support - tiling fixes atmel-hlcdc: - clipping and rotation property fixes qxl: - BO and PRIME improvements - generic fbdev emulation dw-hdmi: - HDMI 2.0 2160p - YUV420 ouput rockchip: - implicit fencing support - reflection proerties virtio-gpu: - use generic fbdev emulation tilcdc: - cpufreq vs crtc init fix rcar-du: - R8A774C0 support - D3/E3 RGB output routing fixes and DPAD0 support - RA87744 LVDS support bochs: - atomic and generic fbdev emulation - ID mismatch error on bochs load meson: - remove firmware fbs" * tag 'drm-next-2019-03-06' of git://anongit.freedesktop.org/drm/drm: (1130 commits) drm/amd/display: Use vrr friendly pageflip throttling in DC. drm/imx: only send commit done event when all state has been applied drm/imx: allow building under COMPILE_TEST drm/imx: imx-tve: depend on COMMON_CLK drm/imx: ipuv3-plane: add zpos property drm/imx: ipuv3-plane: add function to query atomic update status gpu: ipu-v3: prg: add function to get channel configure status gpu: ipu-v3: pre: add double buffer status readback drm/amdgpu: Bump amdgpu version for context priority override. drm/amdgpu/powerplay: fix typo in BACO header guards drm/amdgpu/powerplay: fix return codes in BACO code drm/amdgpu: add missing license on baco files drm/bochs: Fix the ID mismatch error drm/nouveau/dmem: use dma addresses during migration copies drm/nouveau/dmem: use physical vram addresses during migration copies drm/nouveau/dmem: extend copy function to allow direct use of physical addresses drm/nouveau/svm: new ioctl to migrate process memory to GPU memory drm/nouveau/dmem: device memory helpers for SVM drm/nouveau/svm: initial support for shared virtual memory drm/nouveau: prepare for enabling svm with existing userspace interfaces ...
