Subject: [PATCH v3 0/2][XTF] xtf/vpmu VPMU tests
Date: Mon, 24 Apr 2017 13:54:28 -0400 [thread overview]
Message-ID: <20170424175430.395-1-mohit.gambhir@oracle.com> (raw)
This patch series adds tests to validate VPMU functionality on x86. The tests
write and read PMU MSRs to make sure that that they have been exposed
correctly.
The ultimate goal is to address security vulnerabilities, if any, that are
vaguely mentioned in XSA-163 and make VPMU available to guests with reasonable
caveats.
Further testing is required to validate the MSR state save/restore functionality
of the VPMU, concurrent usage of the counters by a number of guests and analyze
if any other non-PMU MSRs have been exposed incorrectly
