inter-flip-IVB.dmesg
Hm, we seem to miss exactly a frame ... A few questions: - How reproducible is this? I'm running some of the mentioned tests in an endless loop on my ilk yet, it seems solid. - Does booting with drm_kms_helper.poll=0 help? - Does this only happen on specific ilk/ivb machines (e.g. specific monitors connected) or on all of them? What about snb? - On a quick lock the ivb machine has only VGA connected. Does the issue also happen on when other outputs instead of VGA are connected, maybe with different screens ...

The reproducing steps just as "./kms_flip --run-subtest flip-vs-absolute-wf_vblank" and it will be always fail on my ilk. 2.I had add drm_kms_helper.poll=0 in grub.cfg,but it doesn't help by booting with it,those subcases still fail on ilk. 3.Yes，we had 4 ilk machines,but only 1 of them had this bug,others on these subcases are all pass. And as same as ilk,only 1 of ivb machines had this bug, not all of ilk & ivb. 4.Snb doesn't had this bug. ***5.On the ivb,I was testing these subcase by 3 monitors connecting at the same time.(VGA & DP & HDMI).Now I retested one time by connectting only 1 monitor.I found you are right,when I connected with VGA,these fail,and all pass except by connecting with VGA. 6.On the ilk,it's a desktop notebook and doesn't connect by none of extranal monitor. > 3.Yes，we had 4 ilk machines,but only 1 of them had this bug,others on these

The one ILK machine existing issue has eDP connected. Is it related to that?
Is this still an issue on latest -nightly? Can you please retest with the following patch applied to latest -nightly? https://patchwork.kernel.org/patch/2709081/ I test it on (drm-intel-next-queued)cab8b5862acd55019fbeede6940d1a601912d6b8 kernel. It doesn't happen on hsw ivb snb ilk.
