Fix that the core PMU is being specified for 2 uncore events. Specify
a PMU for the alderlake UNCORE_FREQ metric.
Conversion script updated in:
https://github.com/intel/perfmon/pull/126
Committer testing:
Before this patch the "perf all metricgroups test" was failing, now:
root@number:~# perf test metric
10: PMU events :
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok
10.5: Parsing of metric thresholds with fake PMUs : Ok
61: Parse and process metrics : Ok
98: perf stat metrics (shadow stat) test : Skip
101: perf all metricgroups test : Ok
102: perf all metrics test : FAILED!
107: perf metrics value validation : Ok
root@number:~#
Test 102 is failing for another reason, not being able to get as many
counters as needed, Ian Rogers suggested disabling the NMI watchdog to
have more counters available:
root@number:/home/acme# cat /proc/sys/kernel/nmi_watchdog
1
root@number:/home/acme# echo 0 > /proc/sys/kernel/nmi_watchdog
root@number:/home/acme# perf test 102
102: perf all metrics test : Ok
root@number:/home/acme#
