Hi Rafael,
Please pull the following cpupower update for Linux 6.4-rc3 or for
a later rc.
This cpupower fixes update for Linux 6.4-rc3 consists of:
- a resource leak fix
- fix drift in C0 percentage calculation due to System-wide TSC read.
To lower this drift read TSC per CPU and also just after mperf read.
This technique improves C0 percentage calculation in Mperf monitor
diff is attached.
thanks,
-- Shuah
