Merge tag 'drm-next-2020-10-15' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie: "Not a major amount of change, the i915 trees got split into display and gt trees to better facilitate higher level review, and there's a major refactoring of i915 GEM locking to use more core kernel concepts (like ww-mutexes). msm gets per-process pagetables, older AMD SI cards get DC support, nouveau got a bump in displayport support with common code extraction from i915. Outside of drm this contains a couple of patches for hexint moduleparams which you've acked, and a virtio common code tree that you should also get via it's regular path. New driver: - Cadence MHDP8546 DisplayPort bridge driver core: - cross-driver scatterlist cleanups - devm_drm conversions - remove drm_dev_init - devm_drm_dev_alloc conversion ttm: - lots of refactoring and cleanups bridges: - chained bridge support in more drivers panel: - misc new panels scheduler: - cleanup priority levels displayport: - refactor i915 code into helpers for nouveau i915: - split into display and GT trees - WW locking refactoring in GEM - execbuf2 extension mechanism - syncobj timeline support - GEN 12 HOBL display powersaving - Rocket Lake display additions - Disable FBC on Tigerlake - Tigerlake Type-C + DP improvements - Hotplug interrupt refactoring amdgpu: - Sienna Cichlid updates - Navy Flounder updates - DCE6 (SI) support for DC - Plane rotation enabled - TMZ state info ioctl - PCIe DPC recovery support - DC interrupt handling refactor - OLED panel fixes amdkfd: - add SMI events for thermal throttling - SMI interface events ioctl update - process eviction counters radeon: - move to dma_ for allocations - expose sclk via sysfs msm: - DSI support for sm8150/sm8250 - per-process GPU pagetable support - Displayport support mediatek: - move HDMI phy driver to PHY - convert mtk-dpi to bridge API - disable mt2701 tmds tegra: - bridge support exynos: - misc cleanups vc4: - dual display cleanups ast: - cleanups gma500: - conversion to GPIOd API hisilicon: - misc reworks ingenic: - clock handling and format improvements mcde: - DSI support mgag200: - desktop g200 support mxsfb: - i.MX7 + i.MX8M - alpha plane support panfrost: - devfreq support - amlogic SoC support ps8640: - EDID from eDP retrieval tidss: - AM65xx YUV workaround virtio: - virtio-gpu exported resources rcar-du: - R8A7742, R8A774E1 and R8A77961 support - YUV planar format fixes - non-visible plane handling - VSP device reference count fix - Kconfig fix to avoid displaying disabled options in .config" * tag 'drm-next-2020-10-15' of git://anongit.freedesktop.org/drm/drm: (1494 commits) drm/ingenic: Fix bad revert drm/amdgpu: Fix invalid number of character '{' in amdgpu_acpi_init drm/amdgpu: Remove warning for virtual_display drm/amdgpu: kfd_initialized can be static drm/amd/pm: setup APU dpm clock table in SMU HW initialization drm/amdgpu: prevent spurious warning drm/amdgpu/swsmu: fix ARC build errors drm/amd/display: Fix OPTC_DATA_FORMAT programming drm/amd/display: Don't allow pstate if no support in blank drm/panfrost: increase readl_relaxed_poll_timeout values MAINTAINERS: Update entry for st7703 driver after the rename Revert "gpu/drm: ingenic: Add option to mmap GEM buffers cached" drm/amd/display: HDMI remote sink need mode validation for Linux drm/amd/display: Change to correct unit on audio rate drm/amd/display: Avoid set zero in the requested clk drm/amdgpu: align frag_end to covered address space drm/amdgpu: fix NULL pointer dereference for Renoir drm/vmwgfx: fix regression in thp code due to ttm init refactor. drm/amdgpu/swsmu: add interrupt work handler for smu11 parts drm/amdgpu/swsmu: add interrupt work function ...
