So I sent out a first step validation check to warn us if we end up
with idle periods that are larger then we expect.
It doesn't yet cap the timekeeping_get_ns() output (like you're patch
effectively does), but it would be easy to do that in a following
patch.
I did notice while testing this that the max_idle_ns (max idle time we
report to the scheduler) for the hpet is only ~16sec, and we'll
overflow after just ~21seconds. This second number maps closely to the
22 second stalls seen in the nmi watchdog reports which seems
interesting, but I also realize that qemu uses a 100MHz hpet, where as
real hardware is likely to be a bit slower, so maybe that's just
chance..
I'd be interested if folks seeing anything similar to Dave would give
my patch a shot.
thanks
