Note this test has been skipped before, however CONFIG_BOOTPARAM_HOTPLUG_CPU0=y was recently added. https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3723/shard-snb2/igt@perf_pmu@cpu-hotplug.html https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3723/shard-hsw2/igt@perf_pmu@cpu-hotplug.html https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3723/shard-apl3/igt@perf_pmu@cpu-hotplug.html https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3723/shard-kbl1/igt@perf_pmu@cpu-hotplug.html https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3723/shard-glkb6/igt@perf_pmu@cpu-hotplug.html (perf_pmu:1650) CRITICAL: Test assertion failure function cpu_hotplug, file perf_pmu.c:915: (perf_pmu:1650) CRITICAL: Failed assertion: (double)(val) <= (1.0 + (tolerance)) * (double)(ref) && (double)(val) >= (1.0 - (tolerance)) * (double)(ref) (perf_pmu:1650) CRITICAL: 'val' != 'ref' (1980000000.000000 not within 5.000000% tolerance of 9014513770.000000) Subtest cpu-hotplug failed. Also, the test has passed on most runs from CI_DRM_3725, to early to say if it's a flip/flopper or fixed.
This one should be fixed with: commit 3fd9b578b3138b04178b4ce8ee4a60e74a16ec91 (upstream/master) Author: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Date: Mon Feb 5 11:38:10 2018 +0000 tests/perf_pmu: Use short batches from hotplug test Please re-open if it won't be.
I will monitor this and close if/when results are OK.
