Hi,
I'm using 4.12.0-rc1 from https://github.com/jwrdegoede/linux-sunxi and got 
the following weird trace yesterday. Previously I've been getting output 
similar to https://www.spinics.net/lists/intel-gfx/msg127638.html, some boots 
on 4.12.0-rc1  I don't get any trace at all.

This is really weird, we are getting the error while we are trying to
acquire the wakelock ... ? Or do we need some other lock before we can
take the wakelock ?

Any input from one of the Intel developers would be appreciated.

Imre pointed out that the current code also fails to re-registering
the notifier from runtime resume. So there's more to fix here.

As far as using the get_noresume() from the notifier, we'll at least
need to reorder the runtime suspend code to do the uncore suspend before
we do the allow_gt_wake(false) etc. Actually, that part of the sequence
seems to be already somewhat wrong because the forcewake timer might
still be active until the uncore suspend, and having active forcewakes
while we've already told the GT wake stuff to stop acting normally
doesn't seem quite right to me.

Thank you for the reply and you're right about not registering the
notifier on runtime-resume I will send a fix for that.

Now about the oops this thread is about, I believe this is triggered
by a race condition, intel_runtime_pm_put() does:

         atomic_dec(&dev_priv->pm.wakeref_count);

         pm_runtime_mark_last_busy(kdev);
         pm_runtime_put_autosuspend(kdev);

And pm_runtime_put_autosuspend() calls intel_runtime_suspend() from
a workqueue, so there is ample of time between the atomic_dec and
intel_runtime_suspend() unregistering the notifier for this oops to
happen. So this really is a false-positive.

Which I believe you already realized and is why you suggested using
intel_runtime_pm_get_noresume().

It took me a while to realize that this is a false positive and all we
really want to do is silence the message and that we don't really need
to take a runtime_pm reference, because we unregister the notifier
(yes I wrote those bits myself, but I've done a lot of other stuff
since).

Unfortunately calling intel_runtime_pm_get_noresume() as you suggest
will not work because it contains a assert_rpm_wakelock_held()
call itself.

So I believe that the only way to silence the false-postive WARN_ON
would be for the notifier to call disable_rpm_wakeref_asserts()
and enable_rpm_wakeref_asserts() around the
intel_uncore_forcewake_get(FORCEWAKE_ALL) call, would that be an
acceptable fix ?

Note that we would then still have the
assert_rpm_device_not_suspended() check implied by
assert_rpm_wakelock_held() to ensure that we're
not calling intel_uncore_forcewake_get during suspend.

Regards,

Hans

wakeref_count is used to catch any HW access without calling
intel_runtime_pm_get() first. This is the majority of cases, for the
exceptions you need to synchronize manually wrt. the HW access in the
runtime suspend hook like in the case of the pmic lock and call
disable_rpm_wakeref_asserts() for the HW access.

Yes, looks ok to me with a comment explaining the synchronization with
runtime suspend. The unregistration of the pmic notifier should happen
before vlv_suspend_complete() as Ville pointed out.
intel_uncore_suspend() could be moved before all the platform specific
suspend handlers as nothing afterwards needs forcewake.
