That's fantastic: # sudo cpupower -c 99 frequency-info info analyzing CPU 99: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 99 CPUs which need to have their frequency coordinated by software: 99 maximum transition latency: Cannot determine or is not supported. hardware limits: 1.50 GHz - 3.72 GHz available frequency steps: 2.00 GHz, 1.70 GHz, 1.50 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.50 GHz and 3.72 GHz. The governor "userspace" may decide which speed to use within this range. current CPU frequency: 2.00 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes Boost States: 0 Total States: 3 Pstate-P0: 2000MHz Pstate-P1: 1700MHz Pstate-P2: 1500MHz Il giorno mar 26 apr 2022 alle ore 12:00 Tummala, Sivaprasad < Sivaprasad.Tummala@amd.com> ha scritto: > [AMD Official Use Only - General] > > > > Hi Antonio, > > > > We are looking into this.
