one could do that but it's not optimal; if the process DOES get waken up earlier, it should take the interrupt then immediately, so that it doesn't have to wake up again when the timer fires. (in fact it would be nice if the guest could somehow poll at the irq mask at waking from idle, so that it wouldn't need a vmexit/entry for every such interrupt, but just do the right thing for all pending work) In addition, yes it'll be a helper function, but since all drivers will want the functionality its probably best off in the generic code -- if you want to mail me at work (you don't), use arjan (at) linux.intel.com Test the interaction between Linux and your BIOS via http://www.linuxfirmwarekit.org ------------------------------------------------------------------------- Take Surveys.
