linux-stable.git/tools/power, branch v6.4 Linux kernel stable tree cpupower: Make TSC read per CPU for Mperf monitor 2023-05-08T16:46:49+00:00 Wyes Karny wyes.karny@amd.com 2023-05-04T06:25:44+00:00 c2adb1877b76fc81ae041e1db1a6ed2078c6746b System-wide TSC read could cause a drift in C0 percentage calculation. Because if first TSC is read and then one by one mperf is read for all cpus, this introduces drift between mperf reading of later CPUs and TSC reading. To lower this drift read TSC per CPU and also just after mperf read. This technique improves C0 percentage calculation in Mperf monitor.
