 Posted: Sat Jul 27, 2019 7:39 pm Post subject: Thermal management advice |
 |
|
I'm trying to migrate one of my oldest laptops to Gentoo from Debian. The last obstacle, that I still cannot solve is the thermal issue. With Debian I use cpufreqd to monitor the CPU temperature and lower the frequency if it is too hot. Unfortunately, in Gentoo this package is deprecated and the one, that is available, only works with 2.6 kernels.
Please advise, how can I achieve a similar behaviour?
I have already tried a tool from Intel, but it does not support that CPU. |

- Which laptop do you have?
- Which CPU and chipset does your laptop have? Please show us the ouput of
Is 'frequency scaling' enabled in the kernel? Please show us the output of
| Code: | | cpupower frequency-info |
Does 'sensors' show you the temperatures of the CPU cores?
Does 'powertop' work? Does tab 'idle stats' show C1/c1E/C3/C6/C7? Does tab 'frequency stats' show you multiple frequencies?

| The kernel now manages this directly, but by default uses the temperature limits set by the BIOS/CPU. If you want to lower them, enable CONFIG_THERMAL_WRITABLE_TRIPS and look in /sys/class/thermal/ and /usr/src/linux/Documentation/thermal/sysfs-api.txt. |

| Ant P., thanks for the suggestion, this looks promising. I'll do the RTFM. |
