dmesg log
Dmesg is incomplete. We cannot check whether the dmc was loaded. If it was, what happens if you don't force load the guc. At least from CI_DRM_3111 KBL-shards: (pm_rc6_residency:1701) CRITICAL: Test assertion failure function residency_accuracy, file pm_rc6_residency.c:85: (pm_rc6_residency:1701) CRITICAL: Failed assertion: ratio > 0.9 && ratio <= 1 (pm_rc6_residency:1701) CRITICAL: Sysfs RC6 residency counter is inaccurate. Subtest rc6-accuracy failed. Example full data: https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3190/shard-kbl7/igt@pm_rc6_residency@rc6-accuracy.html commit 62616c672a623b635141473133674321a4acbdc5 (upstream/master, origin/master, origin/HEAD) Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Oct 17 11:19:38 2017 +0100 igt/pm_rc6_residency: Allow some leeway on the upper %% bound As we use rounding when converting from hw clocks to time, we may report a residency greater than wallclock (by a small margin), so allow us to overshoot by 5% (just due to our inaccuracy). Reproduced on GLK-shards: (pm_rc6_residency:2203) CRITICAL: Test assertion failure function residency_accuracy, file pm_rc6_residency.c:85: (pm_rc6_residency:2203) CRITICAL: Failed assertion: ratio > 0.9 && ratio <= 1 (pm_rc6_residency:2203) CRITICAL: Sysfs RC6 residency counter is inaccurate.

(In reply to Chris Wilson from comment #7) > Which as you will note is from before the fix. I'm sorry Chris. The issue has not been reproduced after CI_DRM_3254 |
