Associated bug: bug 98547
It's a new test. It may simply be asking for much precision. The failure is an error of +-20us, which is greater than a scanline and our accuracy goal is roughly half a scanline.
Yes, this is a new test, not a regression.
I'm reproducing it on IVB. On HSW I now reproduce bug 98547.

(In reply to Chris Wilson from comment #7) > It's a new test. It may simply be asking for much precision. The failure is > an error of +-20us, which is greater than a scanline and our accuracy goal > is roughly half a scanline. The first assertion, that "99.7% samples within one scanline on each side of mean", is also failing (on BDW and HSW from what I've tried). If you relax it to 95%, the test passes - but that's a pretty low MTBF. What makes 5.6s the lowest acceptable MTBF? Also, how much does vblank accuracy depend on the hardware and should the test take that into consideration?
