Comment 35 Mika Kahola 2018-04-18 08:52:49 UTC
I sent a patch

https://patchwork.freedesktop.org/series/41877/

that fixes one anomality. Let's wait for CI runs and see if it would fix the !mismatch error as well.
Comment 36 Lakshmi 2018-09-04 10:15:51 UTC
Mika, looks like the patch didn't fix the mismatch error. This issue occurs with every drm-tip run and frequently with CI DRM Full run as well.
Comment 38 Mika Kahola 2018-11-29 06:52:40 UTC
One idea to tackle crc mismatches.

As we see fifo underruns on tests that fail with crc mismatch we could detect those fifo underruns and skip a crc as we already do when reading crc for the first time.
Comment 39 Daniel Vetter 2019-03-11 09:55:52 UTC
We need to close this one, this bug has become a mess:

- no more fifo underruns it seems

At least 2 new bugs:

1. for igt@kms_plane@pixel-format-pipe-a-planes (also b/c ofc) on icl-u3:

Crash signature is:

Testing format NV12 (0x3231564e) on A.2

Test requirement not met in function run_tests_for_pipe_plane, file ../tests/kms_plane.c:593:

A.2 can also be B.2 for b-planes and C.2 for c-planes


2. bug: igt@kms_plane_multiple@atomic * on icl-u3: No idea yet what's going on there.

3. All the other platforms: Not sure it's a good idea to smash them all into one place. We need to at least separate the bugs where we also have a fifo underrun from crc mistmatches for other reasons. Since my igt patch

commit 4d0d81a2176227a7432762ae095ba386f3c8aba0
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Tue Feb 19 10:11:06 2019 +0100

    lib/crc: Reset fifo underrun reporting for every crc capture

we should be able to tell these two cases apart with 100% accuracy.
Comment 40 Daniel Vetter 2019-03-11 10:08:39 UTC
I think it would also make sense to split kms_plane bugs from kms_plane_multiple. They're testing quite different things really. Maybe only for cases where we do _not_ have fifo underruns.

It has always been, but yeah, it is high time we do something about this bug!

The test got reworked, and kms_plane issues on ICL are now tracked in: https://bugs.freedesktop.org/show_bug.cgi?id=110032

APL issues got moved to https://bugs.freedesktop.org/show_bug.cgi?id=110033

The others will get a per-platform bug as they pop up :)

The issue has been split into this bug: https://bugs.freedesktop.org/show_bug.cgi?id=110037

Agreed... but not too sure how to proceed on this. I should create a view that would allow me to mass-suppress tests in order to deal with this sort of issues...

I also split the igt@kms_plane@plane-position-covered-pipe-[abc]-planes failures to https://bugs.freedesktop.org/show_bug.cgi?id=110038

I will suppress some of the tests and remove them from the filter.
