Commit '16f17eda ("drm/amd/display: Send vblank and user events at vsartup for DCN")' introduces a new way of pageflip completion handling for DCN, and some trouble. The current implementation introduces a race condition, which can cause pageflip completion events to be sent out one vblank too early, thereby confusing userspace and causing flicker: prepare_flip_isr(): 1. Pageflip programming takes the ddev->event_lock. 2. Sets acrtc->pflip_status == AMDGPU_FLIP_SUBMITTED 3. Releases ddev->event_lock. --> Deadline for surface address regs double-buffering passes on target pipe. 4. dc_commit_updates_for_stream() MMIO programs the new pageflip into hw, but too late for current vblank. => pflip_status == AMDGPU_FLIP_SUBMITTED, but flip won't complete in current vblank due to missing the double-buffering deadline by a tiny bit. 5. VSTARTUP trigger point in vblank is reached, VSTARTUP irq fires, dm_dcn_crtc_high_irq() gets called. 6. Detects pflip_status == AMDGPU_FLIP_SUBMITTED and assumes the pageflip has been completed/will complete in this vblank and sends out pageflip completion event to userspace and resets pflip_status = AMDGPU_FLIP_NONE. => Flip completion event sent out one vblank too early. This behaviour has been observed during my testing with measurement hardware a couple of time. The commit message says that the extra flip event code was added to dm_dcn_crtc_high_irq() to prevent missing to send out pageflip events in case the pflip irq doesn't fire, because the "DCH HUBP" component is clock gated and doesn't fire pflip irqs in that state. Also that this clock gating may happen if no planes are active. This suggests that the problem addressed by that commit can't happen if planes are active. The proposed solution is therefore to only execute the extra pflip completion code iff the count of active planes is zero and otherwise leave pflip completion handling to the pflip irq handler, for a more race-free experience. Note that i don't know if this fixes the problem the original commit tried to address, as i don't know what the test scenario was. It does fix the observed too early pageflip events though and points out the problem introduced. Fixes: 16f17eda ("drm/amd/display: Send vblank and user events at vsartup for DCN") Reviewed-by:

[Why] A "dcn20_program_front_end_for_ctx" warning is observed on Renoir. Since the resource definition doesn't explicitly disable triplebuffer flips like Navi10 DC actually attempts to go and setup triplebuffering even when we pass in false to the plane state. If we hit a full update after triplebuffering has been setup we see the assertion since we don't expect full updates while performing triplebuffer flips. Normally this would get reset back to false whne we pass in the new plane state, but since we never actually copy the flag when doing surface updates this doesn't happen. [How] Copy the flag onto the plane update based on the requested surface update state. Signed-off-by:
