I was trying to reproduce the wakeup every 10ms that
Samuel Thibault mentioned, thinking the HPET would improve it.
But for an idle guest in both cases (with and without HPET), the
number of wakeups per second was relatively low (28).
I was referring to vl.c's timeout = 10; which makes the select call
use a timeout of 10ms. That said, "/* If all cpus are halted then wait
until the next IRQ */", so maybe that's why you get slower wakeups per
second. I'm still surprised because of the call to qemu_mod_timer in
pit_irq_timer_update which should setup at least a 100Hz timer with
linux guests (when they don't have HPET available).
The patch disables that when hpet is active.
