Description Imre Deak 2015-11-18 13:26:58 UTC

The condition which triggers this error message in dmesg is normal. The error message should be tuned down, so that the automated tests don't pick it up and flag an error.

One way to fix this:

Comment 1 Jani Nikula 2015-11-18 13:41:46 UTC

Highest priority to get rid of dmesg noise in BAT testing, assign to Imre who has the patch.

Comment 2 Daniel Vetter 2015-11-26 13:20:32 UTC

Temporary fixed with a private branch patch on topic/core-for-CI:

commit 64a93eaebb44c35c50e10144923189c8558d043d
Author: Imre Deak <imre.deak@intel.com>
Date:   Wed Nov 18 12:56:28 2015 +0200

    PCI / PM: tune down RPM suspend error message with EBUSY and EAGAIN retval

We "only" need to make sure here that the patch goes to the right upstream maintainer.

Tested this with

The messages on the kernel ring buffer are printed if debug log level is enabled -- which is by default on dmesg -- assuming that piglit uses warn this should not appear any more.

Can be easily triggered each time by running tests/pm_rpm using gem-execbuf-stress subtest.

Think this can be closed for now.

Comment 4 Marius Vlad 2015-12-04 10:19:44 UTC

So apparently, this reached v5 on m-l.

http://lists.freedesktop.org/archives/intel-gfx/2015-November/081630.html.

It is fixed in drm-intel-nightly (w/ v2), but will eventually be 
replaced by v5.

Comment 5 Jani Nikula 2015-12-04 13:24:38 UTC

We have the fix in a topical branch to shut up the warnings in nightly, but we need to follow-up the commit making it to upstream linux via the right subsystem.

Comment 6 Imre Deak 2015-12-07 16:08:03 UTC

The fix is merged now to Linus' tree and included in -nightly, so closing this.
