Committed on 10/09/2026 at 16:57. Pushed by fanzhuyifan into branch 'master'. backends/drm: match pageflip events to unique commit IDs A DRM file descriptor can outlive its DrmGpu, so events queued before suspend can arrive after the GPU is recreated. Matching only by CRTC can mistake such an event for a newer commit. Pending entries can also retain pointers to commits that have already been destroyed. Give each pageflip submission a unique ID and pass it as the atomic and legacy pageflip user data. Register only when requesting a pageflip event, before the ioctl, so an event arriving before the ioctl returns can be matched without holding the registry mutex across the ioctl. Remove registrations on the first event or commit destruction. Failed commits are discarded by the callers. Copies start unregistered and get their own IDs if submitted, so stale events cannot resolve to another commit even if its address is reused.
