AMD CPU limited to min frequency
Closed this issue · 4 comments
[x] I've read and accepted the Bug Reporting Howto
[x] I've provided all required tlp-stat outputs via Gist (see below)
Describe the bug
CPU max scaling bug that defaults CPU to do its maximum speed to its min frequency speed.
latest 1.7
A clear and concise description of what the bug is.
Expected behavior
If I touched it to min 0 and max 1800 it should do 1.8ghz max not more or less.
A clear and concise description of what you expected to happen.
"Works fine" is not enough to analyze the problem!
To Reproduce
Touching CPU Max Scalling defaults the current cpu policy to be within 400 and 400.
Steps to reproduce the unexpected behavior:
- Does the problem occur on battery or AC or both? I tried battery well for AC not yet.
- Actions to reproduce the behaviour.
- Shell commands entered and their output including error message(s) systemctl status tlp shows no error whatsoever
- Full output of
tlp-statvia https://gist.github.com/ for all

if i set the mim cpu scalling to 400 and max at 3000 it still dont work
Hi,
what you observe is the designed behaviour of the kernel driver amd-pstate-epp with the settings you specified. TLP is not responsible for this.
I suggest you use a less agressive EPP setting than
/etc/tlp.conf L0147: CPU_ENERGY_PERF_POLICY_ON_BAT="power"
By the way, amd-pstate-epp ignores all frequency settings. It doesn't matter what you set there. This is explained in the docs https://linrunner.de/tlp/settings/processor.html#cpu-driver-opmode-on-ac-bat
In active mode, the processor selects the operating frequencies autonomously within the limits imposed by the hardware, including turbo boost. The powersave governor can also lead to max frequency. Configuring the min and max frequency (as shown below) is not supported.
Please ask further questions about which settings to choose and the amd_pstate driver in the forum of your distribution (or in another Linux forum of your choice). The issue tracker is reserved for TLP bug reports. Thanks for your understanding.
if i set iCPU_DRIVER_OPMODE_ON_BAT="guided" or "passive", it does not work regardless having PU_ENERGY_PERF_POLICY_ON_BAT on any settings. I will try to seek out arch linux forums thankyou!
