I attach the dmesg for fbc-1p-primscrn-shrfb-evflip-blt.

But maybe we have another bug when we execute the tests one by one. For exemple when I run # ./intel-gpu-tools/tests/kms_frontbuffer_tracking --run-subtest fbc-1p-rte, I have de DUT crash, but the test pass when we execute all tests. It's really a problem for running the tests with piglit.

Comment 4 Paulo Zanoni 2015-11-13 13:46:10 UTC

I've seen crashes on SKL with eDP+HDMI, but if I use eDP only, it never crashes. I'm also not sure this is due to FBC code.

Can you confirm this?

Comment 5 Olivier Berthier 2015-11-16 10:47:53 UTC

Yes, I confirm, without additional screen there are no crashes and I only have one fail with fbc-farfromfence:

Comment 8 Paulo Zanoni 2016-01-29 21:18:21 UTC

Hi

Can you please retest this with the latest drm-intel-nightly tree and the latest IGT tree?

The only test failing on SKL should be fbc-farfromfence.

Thanks,
Paulo

Comment 9 Olivier Berthier 2016-02-19 09:04:21 UTC

Hi

I confirm, now the only test that fail on Sky Lake is fbc-farfromfence with the latest kernel drm-intel-nightly 4.5.0-rc3 and Intel-gpu-tools 1.13-220 g0a45d6b.

Merged today:

https://cgit.freedesktop.org/xorg/app/intel-gpu-tools/commit/?id=b87188795e9fda89c7e376726283a63817e83c60

I suppose that if you confirm we can close the bug and go into "regression watching mode" for the specific FBC tests.

I still can see problems with 2 monitors, but they are not specific to FBC and I opened #94122 for this.

Thanks for the testing,
Paulo

So resolved as fixed

Comment 12 cprigent 2016-02-22 16:35:47 UTC

fbc-farfromfence failure is tracked by: https://bugs.freedesktop.org/show_bug.cgi?id=94118
So closed
