From: Leo Li <[email protected]> v1 here: https://lore.kernel.org/amd-gfx/[email protected]/ v2 here: https://lore.kernel.org/amd-gfx/[email protected]/
Summary of changes since v2: * Fixed a regression in kms_vrr@flip-basic, which exposed a scenario in optimistic event delivery where wrong vblank timestamps were attached. See new docstrings in patch 2/3 for details. * Readability cleanups in patch 2/3, thanks Michel! v7.0.y based branch here (drops the revert and resolves merge conflicts due to recent refactor of IRQ handlers from amdgpu_dm.c into amdgpu_dm_irq.c): https://gitlab.freedesktop.org/leoli/linux-asdn/-/commits/lileo/flip_done_timeout_corruption_fixes?ref_type=heads A Note on LLM use: Claude helped with code plumbing and IGT testing. The effort of reporting, debugging, spinning up fixes, and testing them, were from humans. Kudos to individuals who collaborated on the amd-gfx mailing list, gitlab, 2026 Display Hackfest, and AMD internal chats, to finally nail down a fix.
