Ah, okay. How about if we add support for ACPI PM timer as platform clock source? Should be easy, any ACPI system will most likely provide it, and it should be much better to use than the PIT (even a 24-bit PM timer should only wrap every 5 seconds). We'll have to prevent dom0 monkeying with the timer: either disallow accesses, or emulate the register. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
