Issue with CPU power restrictions in Debian.
Issue with CPU power restrictions in Debian.
The command returns the scaling governor value for that CPU, indicating how the CPU adjusts its frequency under different workloads.
I adjusted it to performance, and now it runs at 4.2 GHz even when idle, though the power remains capped at 15 watts.
Yes, there's a * in the path, so it'll give you the output for all CPUs (cores/threads). That means the power governor for your CPU is "powersave", so it'll run at the lowest possible power. https://wiki.debian.org/CpuFrequencyScaling You'll want to set that to "conservative" or maybe "ondemand". Personally, I prefer "conservative", because it means things generally stay less noisy. Meanwhile "ondemand" is more aggressive and will scale up a lot sooner.
They're right to be surprised, I guessed you'd miss my previous message. It was just a tiny delay!
You're unsure about adjusting the power limit beyond modifying the CPU governor. It's unclear how you're tracking the measurement—did you confirm the reading is accurate?
"ondemand" is being replaced by a newer option in "schedutil" for faster performance.
You're confirming the RAPL tool results are accurate. Your clock speed and temperatures align with the power usage data from CPU-X.
