Brief summary

The CPU is stuck at the same frequency (2111.992), both when idle and during heavy computation

How reproducible

100%

How to reproduce

• Run watch -n1 "cat /proc/cpuinfo | grep MHz"
• Observe that nothing changes for a long time, even when switching between idle and computation-heavy tasks

Expected behavior

The frequencies should change

Actual behavior

They all stay the same (2111.992)

Screenshots

Additional context

This probably is an issue with how the frequencies are reported to OS, or maybe even how Qubes OS handles them because the fan speeds audibly change when switching tasks, which would imply that the CPU frequencies change as well, generating less or more heat

Solutions you've tried

Determining CPU frequency in Qubes is a bit different , /proc/cpuinfo does not report the actual frequency at runtime

Right, thanks...
