Merge tag 'drm-next-2020-04-01' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie: "This is the main drm pull request for 5.7-rc1. Highlights: - i915 enables Tigerlake by default - i915 and amdgpu have initial OLED backlight support [ Jani Nikula pipes up and points out that we've had a bunch of "initial support" code for a long time already, but only now Lyude made it actually work on real world machines ] - vmwgfx add support to enable OpenGL 4 userspace - zero length arrays are mostly removed. Detailed summary: new driver: - tidss: TI Keystone platform display subsystem core: - new drm device warn macros - mode config valid for memory constrained devices - bridge bus format negotation - consolidated fake vblank event handling - dma_alloc related cleanups - drop get_crtc callback - dp: DP1.4 EDID corruption test - EDID CEA detailed timings improvements - relicense some code to dual GPL2/MIT - convert core vblank support to per-crtc support - rework drm_global_mutex - bridge rework to allow omap_dss custom driver removeal - remove drm_fb_helper connector interrfaces - zero-length array removal scheduler: - support for modifying the sched list - revert job distribution optimization - helper to pick least loaded scheduler - race condition fix mst: - various fixes - remove register_connector callback i915: - uapi to allows userspace specific CS ring buffer sizes - Tigerlake enablement patches + Tigerlake enabled by default - new sysfs entries for engine properties - display/logging refactors - eDP/DP fixes for DPCD - Gen7 back to aliasing-ppgtt - Gen8+ irq refactor - Avoid globals - GEM locking fixes and simplifications - Ice Lake and Elkhart Lake fixes and workarounds - Baytrail/Haswell instability fix - GVT - VFIO edid better support amdgpu: - Rework VM update handling in preparation for HMM support - drm load/unload removal fixups - USB-C PD firmware updates - HDCP srm support - Navi/renoir PM watermark fixes - OLED panel support - Optimize debugging vram access - Use BACO for runtime pm - DC clock programming optimizations and fixes - PSP fw loading sequence updates - Drop DRIVER_USE_AGP - Remove legacy drm load and unload callbacks - ACP Kconfig fix - Lots of fixes across the driver amdkfd: - runtime pm support - more gfx config details in amdgpu radeon: - drop DRIVER_USE_AGP vmwgfx: - Disable DMA when SEV encryption in use - Shader Model 5 support - needed for GL4 support msm: - DPU resource manager refactor - dpu using atomic global state mediatek: - MT8183 DPI support etnaviv: - out-of-bounds read fix - expose feature flags for GC400 STM32MP1 SoC - runtime suspend entry fix - dma32 zone fix hisilicon: - mode selection fixes meson: - YUV420 support lima: - add support for heap buffers tinydrm: - removal of owner field - explicit DT dependency removal - YAML schema conversion tegra: - misc cleanups tidss: - new driver virtio: - better batching of notifications to host - memory handling reworked - shmem + gpu context fixes hibmc: - add gamma_set support - improve DPMS support pl111: - Integrator IM-PD1 support sun4i: - LVDS support for A20 + A33 - DSI panel handling improvements" * tag 'drm-next-2020-04-01' of git://anongit.freedesktop.org/drm/drm: (1537 commits) drm/i915/display: Fix mode private_flags comparison at atomic_check drm/i915/gt: Stage the transfer of the virtual breadcrumb drm/i915/gt: Select the deepest available parking mode for rc6 drm/i915: Avoid live-lock with i915_vma_parked() drm/i915/gt: Treat idling as a RPS downclock event drm/i915/gt: Cancel a hung context if already closed drm/i915: Use explicit flag to mark unreachable intel_context drm/amdgpu: don't try to reserve training bo for sriov (v2) drm/amdgpu/smu11: add support for SMU AC/DC interrupts drm/amdgpu/swSMU: handle manual AC/DC notifications drm/amdgpu/swSMU: handle DC controlled by GPIO for navi1x drm/amdgpu/swSMU: set AC/DC mode based on the current system state (v2) drm/amdgpu/swSMU: correct the bootup power source for Navi1X (v2) drm/amdgpu/swSMU: use the smu11 power source helper for navi1x drm/amdgpu/smu11: add a helper to set the power source drm/amd/swSMU: add callback to set AC/DC power source (v2) drm/scheduler: fix rare NULL ptr race drm/amdgpu: fix the coverage issue to clear ArcVPGRs drm/amd/display: Fix pageflip event race condition for DCN. drm/[radeon|amdgpu]: Remove HAINAN board from max_sclk override check ...
