TurboBoost doesn't work on RHOCP4.8 CoreOS node
Issue
- TurboBoost doesn't work with acpi-cpufreq driver on RHOCP4.8 CoreOS node
# cpupower frequency-info
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us
hardware limits: 800 MHz - 2.60 GHz <<-------
available frequency steps: 2.60 GHz, 2.60 GHz, 2.50 GHz, 2.30 GHz, 2.20 GHz, 2.10 GHz, 2.00 GHz, 1.80 GHz, 1.70 GHz, 1.60 GHz, 1.40 GHz, 1.30 GHz, 1.20 GHz, 1.10 GHz, 900 MHz, 800 MHz
available cpufreq governors: conservative ondemand userspace powersave performance
current policy: frequency should be within 800 MHz and 2.60 GHz. <<-------
The governor "performance" may decide which speed to use
within this range.
current CPU frequency: 2.60 GHz (asserted by call to hardware)
boost state support:
Supported: yes
Active: yes
- On the other hand, it works with intel_pstate driver on other node:
