Subject: [PATCH v3 0/2] VPMU management update
Date: Wed, 22 Feb 2017 13:24:26 -0500 [thread overview]
Message-ID: <1487787868-6053-1-git-send-email-boris.ostrovsky@oracle.com> (raw)
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
