xenoprof: flush remaining smples when sampling is stopped. Xenoprof notifies guest kernel via VIRQ_XENOPROF when sampled. But it does coarsly based on heuristic so that sometimes VIRQ_XENOPROF isn''t delivered resulting in that oprofile daemon collects no sample. To avoid that situation, always send VIRQ_XENOPROF when sampling is stopped. -- yamahata __________________________________________...

These patches address issues in the kernel part of xenoprof: * Ill-advised use of on_each_cpu() can lead to sleep with interrupts disabled. * Race conditions in active_domains code. * Cleanup of active_domains code. Comments welcome. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

''cat /proc/interrupts'' in a Linux PV domain shows interrupts starting at 256 and labelled as ''Dynamic-irq''. Are these available in a HVM domain, eg under Windows?
