[Xen-devel] [PATCH v3 0/2] VPMU management update

[Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>]

Changes to how the hypervisor allocates and keeps track of active
VPMUs. The main purpose is to fix vpmu_enabled() reporting but this
also makes VPMU ref counting more consistent.


Boris Ostrovsky (2):
  x86/vpmu: Add get/put_vpmu() and VPMU_AVAILABLE
  x86/vpmu: Disable VPMU if guest's CPUID indicates no PMU support
