JIRA: https://issues.redhat.com/browse/RHEL-34610 commit e48934c9f1048ed4640b60321baf1986d1a470e1 Author: Patryk Wlazlyn <patryk.wlazlyn@linux.intel.com> Date: Thu Jan 11 16:42:22 2024 +0100 tools/power turbostat: Add reading aperf and mperf via perf API By using the perf API we spend less time in between the reads of the counters, resulting in more accurate calculations of the dependent metrics. Using perf API is also usually faster overall, although cache miss, if we get one, is more costly when using perf vs MSR driver. We would fallback to the msr reads if the sysfs isn't there or when in --no-perf mode.
