Thomas Renninger c8cfc3c6bf cpupower: Provide -c param for cpupower monitor to schedule process on all cores ... If an MSR based monitor is run in parallel this is not needed. This is the default case on all/most Intel machines. But when only sysfs info is read via cpupower monitor -m Idle_Stats (typically the case for non root users) or when other monitors are PCI based (AMD), Idle_Stats, read from sysfs can be totally bogus: cpupower monitor -m Idle_Stats PKG |CORE|CPU | POLL | C1-N | C3-N | C6-N 0| 0| 0| 0.00| 0.00| 0.24| 99.81 0| 0| 32| 0.00| 0.00| 0.00| 100.7 ... 0| 17| 20| 0.00| 0.00| 0.00| 173.1 0| 17| 52| 0.00| 0.00| 0.07| 173.0 0| 18| 68| 0.00| 0.00| 0.00| 0.00 0| 18| 76| 0.00| 0.00| 0.00| 0.00 ... With the -c option all cores are woken up and the kernel did update cpuidle statistics before reading out sysfs. This causes some overhead. Therefore avoid if possible, use if needed: cpupower monitor -c -m Idle_Stats PKG |CORE|CPU | POLL | C1-N | C3-N | C6-N 0| 0| 0| 0.00| 0.00| 0.00| 100.2 0| 0| 32| 0.00| 0.00| 0.00| 100.2 ... 0| 8| 8| 0.00| 0.00| 0.00| 99.82 0| 8| 40| 0.00| 0.00| 0.00| 99.81 0| 9| 24| 0.00| 0.00| 0.00| 100.3 0| 9| 56| 0.00| 0.00| 0.00| 100.2 0| 16| 4| 0.00| 0.00| 0.00| 99.75 0| 16| 36| 0.00| 0.00| 0.00| 99.38 ...
