Description manowar@altlinux.org 2022-04-26 21:42:10 MSK

На ядрах p10 куда-то подевались почти все сенсоры и, в частности, все pwm* для вентиляторов. Проверено на двух компьютерах с разными материнскими платами и bios.

Ранее (в p9) сенсоры располагались вот тут: /sys/devices/platform/nct6775.3712/hwmon/hwmon2 и именовались как temp* и pwm*. Теперь же поиск файлов с похожими именами во всём дереве /sys ничего не находит. Модуль hwmon загружен.

Из похожего в сети удалось пока найти только это:
https://askubuntu.com/questions/1232175/sys-class-hwmon-hwmonx-pwm1-missing-after-upgrading-to-20-04 . Но там до причины не докопались.

Comment 1 Vitaly Chikunov 2022-05-09 17:43:43 MSK

Пришлите, пожалуйста, вывод `find /sys -ls` до и после пропадания.

Comment 2 Vitaly Chikunov 2022-05-09 17:49:00 MSK

Да так же не помешает вывод dmesg и lsmod.

Comment 3 Sergey Ivanov 2024-04-26 10:54:33 MSK

Проверил данную ошибку в репозитории p9 и p10. После установки чистой системы и обновления до репозитория отображается только температура

После добавления сенсоров командой sensors-detect, они корректно отображаются в директории /sys

Так же корректно выполняется изменение скорости работы вентилятороов

Проверил на образах:
alt-kworkstation-9.2-x86-64
ядра:
5.4.274-std-def-alt1
5.10.213-un-def-alt1

alt-kworkstation-10.2.1-x86-64
ядра:
5.10.213-std-def-alt1
6.1.85-un-def-alt1

На данных системах и всех указанных ядрах поведение не отличается
