[1/3] drm/syncobj: Add deadline support for syncobj waits commit: 8570c27932e132d2663e8120311891deb2a853de [2/3] dma-buf/sync_file: Add SET_DEADLINE ioctl commit: 63ee44540205d993854f143a5ab1d7d9e63ffcf1 [3/3] dma-buf/sw_sync: Add fence deadline support commit: 70e67aaec2f4706df0006423eebca813b00f5840 Best regards,
From: Rob Clark <robdclark@chromium.org> This is a re-post of the remaining patches from: https://patchwork.freedesktop.org/series/114490/ Part of the hold-up of the remaining uabi patches was compositor support, but now an MR for kwin exists: https://invent.kde.org/plasma/kwin/-/merge_requests/4358 The syncobj userspace is: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/21973 v1: https://patchwork.freedesktop.org/series/93035/ v2: Move filtering out of later deadlines to fence implementation to avoid increasing the size of dma_fence v3: Add support in fence-array and fence-chain; Add some uabi to support igt tests and userspace compositors. v4: Rebase, address various comments, and add syncobj deadline support, and sync_file EPOLLPRI based on experience with perf/ freq issues with clvk compute workloads on i915 (anv) v5: Clarify that this is a hint as opposed to a more hard deadline guarantee, switch to using u64 ns values in UABI (still absolute CLOCK_MONOTONIC values), drop syncobj related cap and driver feature flag in favor of allowing count_handles==0 for probing kernel support. v6: Re-work vblank helper to calculate time of _start_ of vblank, and work correctly if the last vblank event was more than a frame ago. Add (mostly unrelated) drm/msm patch which also uses the vblank helper. Use dma_fence_chain_contained(). More verbose syncobj UABI comments. Drop DMA_FENCE_FLAG_HAS_DEADLINE_BIT. v7: Fix kbuild complaints about vblank helper. Add more docs. v8: Add patch to surface sync_file UAPI, and more docs updates. v9: Repost the remaining patches that expose new uabi to userspace.
