The ticker doesn't tick when you block. Your idle loop needs to disable interrupts, set a one-shot timer, then block. See safe_halt() in our Linux source tree (arch/i386/kernel/time-xen.c) -- the function expects to be called with interrupts disabled and caller should also have already checked for any other threads being runnable. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
