Hi, in order to support kdump/kexec on multiprocessor HVM guests, the patch at http://xenbits.xensource.com/xen-unstable.hg/rev/19907 was committed. The patch migrates all timers (via the pt infrastructure) to a VCPU whose LAPIC is configured to receive the legacy 8259 interrupts. In doing this, however, the pmtimer is left out. Its timer won't ever move away from VCPU#0. Is there a reason for this, or is it just an oversight? Thanks in advance, Paolo _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
