Pull drm updates from Dave Airlie: "This starts to support NVIDIA volta hardware with nouveau, and adds amdgpu support for the GPU in the Kabylake-G (the intel + radeon single package chip), along with some initial Intel icelake enabling. Summary: New Drivers: - v3d - driver for broadcom V3D V3.x+ hardware - xen-front - XEN PV display frontend core: - handle zpos normalization in the core - stop looking at legacy pointers in atomic paths - improved scheduler documentation - improved aspect ratio validation - aspect ratio support for 64:27 and 256:135 - drop unused control node code. i915: - Icelake (ICL) enabling - GuC/HuC refactoring - PSR/PSR2 enabling and fixes - DPLL management refactoring - DP MST fixes - NV12 enabling - HDCP improvements - GEM/Execlist/reset improvements - GVT improvements - stolen memory first 4k fix amdgpu: - Vega 20 support - VEGAM support (Kabylake-G) - preOS scanout buffer reservation - power management gfxoff support for raven - SR-IOV fixes - Vega10 power profiles and clock voltage control - scatter/gather display support on CZ/ST amdkfd: - GFX9 dGPU support - userptr memory mapping nouveau: - major refactoring for Volta GV100 support tda998x: - HDMI i2c CEC support etnaviv: - removed unused logging code - license text cleanups - MMU handling improvements - timeout fence fix for 50 days uptime tegra: - IOMMU support in gr2d/gr3d drivers - zpos support vc4: - syncobj support - CTM, plane alpha and async cursor support analogix_dp: - HPD and aux chan fixes sun4i: - MIPI DSI support tilcdc: - clock divider fixes for OMAP-l138 LCDK board rcar-du: - R8A77965 support - dma-buf fences fixes - hardware indexed crtc/du group handling - generic zplane property support atmel-hclcdc: - generic zplane property support mediatek: - use generic video mode function exynos: - S5PV210 FIMD variant support - IPP v2 framework - more HW overlays support" * tag 'drm-next-2018-06-06-1' of git://anongit.freedesktop.org/drm/drm: (1286 commits) drm/amdgpu: fix 32-bit build warning drm/exynos: fimc: signedness bug in fimc_setup_clocks() drm/exynos: scaler: fix static checker warning drm/amdgpu: Use dev_info() to report amdkfd is not supported for this ASIC drm/amd/display: Remove use of division operator for long longs drm/amdgpu: Update GFX info structure to match what vega20 used drm/amdgpu/pp: remove duplicate assignment drm/sched: add rcu_barrier after entity fini drm/amdgpu: move VM BOs on LRU again drm/amdgpu: consistenly use VM moved flag drm/amdgpu: kmap PDs/PTs in amdgpu_vm_update_directories drm/amdgpu: further optimize amdgpu_vm_handle_moved drm/amdgpu: cleanup amdgpu_vm_validate_pt_bos v2 drm/amdgpu: rework VM state machine lock handling v2 drm/amdgpu: Add runtime VCN PG support drm/amdgpu: Enable VCN static PG by default on RV drm/amdgpu: Add VCN static PG support on RV drm/amdgpu: Enable VCN CG by default on RV drm/amdgpu: Add static CG control for VCN on RV drm/exynos: Fix default value for zpos plane property ...
