I double checked that INTEL_ARCH_LLC_MISSES_INDEX is the only event that fails, test survived whole night with only it commented out. 2. using CLFLUSH instead of CLFLUSHOPT doesn't help Should we disable this event for now to avoid the failure until we figure o= ut how to use this event in a reliable way? Best regards, Maxim Levitsky PS: I also did initial testing for running this test nested - it fails with invalid guest state in L1, but only sometimes.=20 I'll investigate that further soon. --=20 You may reply to this email to add a comment.
