CPUIDLE: Avoid remnant LAPIC timer intr while force hpetbroadcast LAPIC will stop during C3, and resume to work after exit from C3. Considering below case: The LAPIC timer was programmed to expire after 1000us, but CPU enter C3 after 100us and exit C3 at 9xxus. 0us: reprogram_timer(1000us) 100us: entry C3, LAPIC timer stop 9xxus: exit C3 due to unexpected event, LAPIC timer continue running 10xxus: reprogram_timer(1000us), fail due to the past expiring time. ......: no timer softirq raised, no chan...

Hi, Is there a specific latency that asterisk accepts? I encountered a problem wherein when the latency was unusually high,my xlite's (i have 2 xlite) cannot register. but when the link suddenly went stable, the x-lite just registered. what i forgot to look at is if the registration packet is reaching my asterisks. ------ when xlite cannot register --------------- Pinging

...ted patches are reasonable or could have side-effects. Interesting results in the link above: - xpin decreases startup time of vms in a bootstorm - xpin has a pathological case when the vms are burning lots of cpu - nopin produces an interesting cluster of high event channel latency between 100us-1000us when enough vms are using lots of cpu - experimental tweaks on the xen credit1 scheduler code that cause the xpin pathological case to go away, and other increases (and sometimes decreases) in bootstorm and vm density performance. cheers, Marcus
