I've taken just the latter part. Thanks for accept most of these patches. As to disable/enable_LAPIC_timer(), I add them because some platforms require the LAPIC timer intr being disabled before entering C3, otherwise there may be some unexpected things. As a reference, Linux kernel always do so. Jimmy _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
