Title:
tools/power/cpupower: Fix Pstate frequency reporting on AMD Family
1Ah CPUs
Status in linux package in Ubuntu:
New
Bug description:
cpupower utility reports incorrect pstates in one portion of its
output on Turin.
root@volcano-ef0fhost:/home/amd# 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: Cannot determine or is not supported.
hardware limits: 1.50 GHz - 3.25 GHz
available frequency steps: 1.90 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 1.90 GHz.
The governor "schedutil" may decide which speed to use
within this range.
current CPU frequency: 1.50 GHz (asserted by call to hardware)
boost state support:
Supported: yes
Active: yes
Boost States: 0
Total States: 3
Pstate-P0: 24800MHz
Pstate-P1: 16800MHz
Pstate-P2: 8800MHz
This issue occurs both with the distro cpufreq utility that comes with
Ubuntu 22.04 5.15.0.87 kernel-tools package as well as the upstream
cpufreq utility.
The fix is commit 43cad521c6d :
tools/power/cpupower: Fix Pstate frequency reporting on AMD Family 1Ah
CPUs
