--- Comment #2 from Matt Roper <matthew.d.roper at intel.com> ---
This test attempts to toggle the offline/online status of CPUs to ensure that
the hotplugging of CPUs does not impact the busyness stats returned by the perf
pmu api.  IGT commit ec872b7dc1 ("tests/perf_pmu: Handle CPU hotplug failures
better") mentions "CPU hotplug, especially CPU0, can be flaky on commodity
hardware" and that's what we're running into here.  For whatever reason, the
kernel is not able to take CPU0 offline, so the test prints the igt_warn()
message and then skips.

The behavior here is not related to graphics at all, just the inability to
offline CPU0 on the system, so there should be no impact to end users.  As
such, marking priority/importance as low.  The inability to turn off the CPU is
a semi-expected behavior on some platforms, so going forward it would probably
be best to downgrade the message to an igt_info() so that it won't get flagged
by CI; there isn't anything we can/should do in response to this message.
