[Xen-devel] [PATCH v3 0/2][XTF] xtf/vpmu VPMU tests

[Mohit Gambhir <mohit.gambhir@xxxxxxxxxx>]

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
