[Xen-devel] [PATCH v3 2/3] x86/VPMU: Disable VPMU when NMI watchdog is on

NMI watchdog sets APIC_LVTPC register to generate an NMI when PMU counter overflow occurs. This may be overwritten by VPMU code later, effectively turning off the watchdog. We should disable VPMU when NMI watchdog is running. Signed-off-by: Boris Ostrovsky boris.ostrov...@oracle.com ---
