State : failure
This seems to be a random failure getting assigned to this series, this series
only affects systems which have a PUNIT mutex as detected by:
drivers/i2c/busses/i2c-designware-baytrail.c
Which I'm pretty sure this system does not have.
Looking closer, this series does slightly modify the timing of
intel_uncore_resume_early(), as that now takes and releases
the mutex behind iosf_mbi_punit_acquire(); twice rather then
just once. I could extend the first patch in the series
to also add an unlocked variant of iosf_mbi_register_pmic_bus_access_notifier
and only take the lock once, from a race pov this is not
necessary, but it would save having to take the lock
twice.
I still think there is another root cause to the problem
the CI caught though, the problem is the
GEM_BUG_ON in drivers/gpu/drm/i915/intel_lrc.c at
line 782, which has a big comment on top on why
calling intel_runtime_pm_get() is not necessary there
maybe there is a path where it is actually necessary
and we are hitting a race here ?
