Subject: [kvm-unit-tests patch v6 00/18] pmu test bugs fix and improvements
Changes:
v5 -> v6:
* limit maximum fixed counters number to
MIN(pmu.nr_fixed_counters, ARRAY_SIZE(fixed_events)) to avoid
out-of-bound access for fixed_events[]. If supported fixed counters
number is larger than array size of fixed_events[], print message to
remind to update test case. (Jim)
* limit instructions & branches events precise validation for only
Intel processors. (Sandipan Das)
KUT/pmu test passes on Intel Sapphire Rapids platform.
