Debian zaboravio skaliranje brzine CPU-a
Jucer sam napravio upgrade Debiana sa Jessie na Stretch, na starom laptopu. U prvi trenutak mi se cinilo kao pregrijavanje, ali je laptop cijelo vrijeme ostao hladan.
Na kraju se ispostavilo da je sustav uzeo 800 MHz kao gornju granicu brzine. Procesor je 2-jezgreni AMD Turion na 1.6 GHz.
Kod:
> cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to [email protected], please.
analyzing CPU 0:
driver: powernow-k8
CPUs which run at the same hardware frequency: 0 1
CPUs which need to have their frequency coordinated by software: 0 1
maximum transition latency: 109 us.
hardware limits: 800 MHz - 1.60 GHz
available frequency steps: 1.60 GHz, 800 MHz
available cpufreq governors: userspace, powersave, conservative, ondemand, performance, schedutil
current policy: frequency should be within 800 MHz and 800 MHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz.
cpufreq stats: 1.60 GHz:0.07%, 800 MHz:99.93% (9)
analyzing CPU 1:
driver: powernow-k8
CPUs which run at the same hardware frequency: 0 1
CPUs which need to have their frequency coordinated by software: 0 1
maximum transition latency: 109 us.
hardware limits: 800 MHz - 1.60 GHz
available frequency steps: 1.60 GHz, 800 MHz
available cpufreq governors: userspace, powersave, conservative, ondemand, performance, schedutil
current policy: frequency should be within 800 MHz and 800 MHz.

Nisam ga uspio natjerati da primi 1.6 GHz kao gornju granicu brzine, ni rucno, ni programima koji su za to obicno namjenjeni.
Ima li netko nekakvu ideju?

Si mu prvo dati da radi nesto sto je CPU intensive?
Na mom laptopu koji je isto AMD samo što vrtim na njemu centos 7 frekvencija je na minimalnoj ali kada mu upalim virtualbox ili pokrenem video cpu frekvencija se podigne.

Nauci se citati. Ako ti ljepo pise da sam problem otkrio po nedostatku performansi, ocita implikacija je da sam laptopu dao CPU intenzivan zadatak koji nije obavio ocekivanom brzinom.

Ne mogu reci da imam iskustva na linuxu, vezano za takve probleme.
Ono sto citam na debian wikiju, puno je nadrobljeno... prepostavljam da is probao staviti policy na iskljucivo "performance", jeli u tom slucaju isti range odnosno output komande gore.
Jesi li probao igrati sa nice tijekom izvodjenja programa ?
Kakav je to program, jeli moguce da je update distribucije podigao verzije, pa se problem samo ovako manifestira (iako mi je cudan output od 800 do 800, ovo je moguce bug ha?)
Nije lose pogledati i metriku za proc tijekom rada, npr mpstat.
Bootaj live cd prethodne distre pa probaj ako nije prekompleksan i ogroman enviroment.
Spretno

Izgleda da je problem do kernela. Koristim stari kernel kao workaround.

Čitajući diskusiju, bug kao takav nije rješen nego su samo iščupana van dva changeseta koja su uzrokovala tu regresiju. Maintainera očigledno ta regresija ne zanima, jer odgovora od njega nije bilo. Ni bu ni me.
Jesi ti siguran da hoćeš takav sustav gdi takvi ljudi prčkaju po njemu za svakodnevno korištenje?

Primjetio sam. Illumos ekipa je daleko profesionalnija.
