Hi Guys,
I have been chasing spurious clockevent interrupts (In HIGHRES mode) on my x86
IvyBridge server and stuck on some blockers (mostly due to lack of knowledge)
and need some help..
What does spurious mean ?
I take it as the case when a core is unnecessarily interrupted by the clockevent
device while we didn't wanted it to.
I tried to catch them with the help of few new trace points in
hrtimer_interrupt() when it didn't serviced any pending hrtimers..
The causes I could find:
- Clockevent device's counter overflow: When we need to program a clockevt
device for times larger than it can handle, we program it for max time and
then reprogram again on expiration. Because of hardware counter limitations we
have to do it this way and this isn't really a spurious interrupt as we
programmed it that way.
- Hardware timer firing before its expiration: Yes, its hard to digest but from
my tests it looks like this does happen. Will circulate another mail once I am
sure about it.
- Difference between time returned by hrtimer_update_base() and clockevt
device's notion of time: Wanted to discuss this here..
An example of what I am witnessing in my tests:
clockevt device programmed to fire after 199 ms and it fires exactly after that
time (Verified with ftrace time-diff and tsc diff [tsc: timestamp counter
instructions for x86]).
But when hrtimer_interrupt() tries to find the hrtimer for which the event
occurred, it finds the value returned by hrtimer_update_base() being lesser than
the softexpires of the timer for which the event was programmed. And the diff is
approximately 1 us most of the times I see the spurious interrupt.

Tested on: Ivybrdge V2, 12 core X86 server, though it occurs on ARM as well
(but not that frequent).

Somehow one of the instance of freeing resources failed to use kfree_rcu() and
used kfree() instead. This might cause problems as the node might be referenced
by readers under rcu locks and we must wait for the rcu grace period as well.
While we are at it, also update comment over 'struct device_opp' to mention why
we are waiting for both rcu and srcu grace periods.
Fixes: 129eec55df6a ("PM / OPP Introduce APIs to remove OPPs")

Hi Rafael,
Few more updates for the opp layer. First one is a potential bug fix and rest
are cleanups.
