Comment 3 Chris Wilson 2019-09-09 07:39:54 UTC

Any squawk over netconsole or serial?

Comment 4 Chris Wilson 2019-09-10 12:51:31 UTC

Next clue: https://patchwork.freedesktop.org/patch/329953/?series=66483&rev=1
=> rc6/forcewake is adrift.

Comment 5 Chris Wilson 2019-09-10 16:14:39 UTC

Disabled rc6 -> https://intel-gfx-ci.01.org/tree/drm-tip/Patchwork_14343/?
No improvement, forcewake ftw.

Tried again with an explicit rc6 disable; success.

Band aid fix,

    drm/i915/tgl: Disable rc6 for debugging
    
    Empirical evidence from CI tells us that our rc6 setup for Tigerlake is
    off. Disable rc6 on tgl temporary so that we gain CI coverage as we
    prepare a fix. It also appears that the BIOS on our tgl leaves rc6
    enabled, so we have to explicitly disable it on init.

Should leave pm_rpm failing as a suitable reminder to fix rc6.

I guess this patch and the forcewake ones fixed the issue. I will still keep it open for a bit longer because rc6 was re-enabled and I want to prove that it indeed was well fixed.

Thanks!

This isssue is reproducible 100%.

Comment 19 Francesco Balestrieri 2019-11-06 05:17:58 UTC

Mika, Chris, did this turn out to be another occurrence of the multi-engine problem?

Comment 20 Francesco Balestrieri 2019-11-11 09:32:48 UTC


*** This bug has been marked as a duplicate of bug 111880 ***

Comment 21 Francesco Balestrieri 2019-11-11 09:34:06 UTC

This is the original report of the issue with parallel engines. Given that Bug 111880 is where we track that problem, resolving this one as duplicate.
