…m/kernel Pull drm fixes from Dave Airlie: "Regular weekly fixes. This is a bit larger than usual but doesn't seem too crazy. Most of it is vmwgfx changes that fix a bunch of issues with wayland userspaces with dma-buf/external buffers and modesetting fixes. Otherwise it's kinda spread out, v3d fixes some new ioctls, nouveau has regression revert and fixes, amdgpu, i915 and ast have some small fixes, and some core fixes spread about. client: - fix error code atomic: - allow damage clips with async flips - allow explicit sync with async flips kselftests: - fix dmabuf-heaps test panic: - fix schedule_work in panic paths panel: - fix OrangePi Neo orientation gpuvm: - fix missing dependency amdgpu: - SMU 14.x update - Fix contiguous VRAM handling for IB parsing - GFX 12 fix - Regression fix for old APUs i915: - Static analysis fix for int overflow - Fix for HDCP2_STREAM_STATUS macro and removal of PWR_CLK_STATE for gen12 nouveau: - revert busy wait change that caused a resume regression - fix buffer placement fault on dynamic pm s/r - fix refcount underflow ast: - fix black screen on resume - wake during connector status detect v3d: - fix issues with perf/timestamp ioctls vmwgfx: - fix deadlock in dma-buf fence polling - fix screen surface refcounting - fix dumb buffer handling - fix support for external buffers - fix overlay with screen targets - trigger modeset on screen moves" * tag 'drm-fixes-2024-08-02' of https://gitlab.freedesktop.org/drm/kernel: (31 commits) Revert "nouveau: rip out busy fence waits" nouveau: set placement to original placement on uvmm validate. drm/atomic: Allow userspace to use damage clips with async flips drm/atomic: Allow userspace to use explicit sync with atomic async flips drm/i915: Fix possible int overflow in skl_ddi_calculate_wrpll() drm/i915/hdcp: Fix HDCP2_STREAM_STATUS macro drm/ast: astdp: Wake up during connector status detection i915/perf: Remove code to update PWR_CLK_STATE for gen12 kselftests: dmabuf-heaps: Ensure the driver name is null-terminated drm/client: Fix error code in drm_client_buffer_vmap_local() drm/amdgpu: Fix APU handling in amdgpu_pm_load_smu_firmware() drm/amdgpu: increase mes log buffer size for gfx12 drm/amdgpu: fix contiguous handling for IB parsing v2 drm/amdgpu/pm: support gpu_metrics sysfs interface for smu v14.0.2/3 drm/vmwgfx: Trigger a modeset when the screen moves drm/vmwgfx: Fix overlay when using Screen Targets drm/vmwgfx: Add basic support for external buffers drm/vmwgfx: Fix handling of dumb buffers drm/vmwgfx: Make sure the screen surface is ref counted drm/vmwgfx: Fix a deadlock in dma buf fence polling ...
