How is this > supposed to be handled with atomic? First let me ask you - why we have to enable vlbank as part of pflip, I understand why it has to be enbbled in WAIT_FOR_VBLANK IOCTL but not sure about PFLIP IOCTL. IMHO in atomic as before in legacy page_flip, it's up to the driver implementation in atomic_commit hook to manage vblank ISR on,off. > > Andrey, did you check via code audit and/or te...

This series is a folow-up on https://patchwork.kernel.org/patch/9501787/ The first patch makes changes to atomic helpers to allow for drives with ASYNC flip support to use them. Patch 2 is to use this in AMDGPU/DC. Patch 3 is possible cleanup in nouveau/kms who seems to have to duplicate the helper as we did to support ASYNC flips. v2: Resend drm/atomic: Save flip flags in drm_plane_state
