Вопрос (извините за длинный дамп, но я думаю, что это могло бы быть полезно):
Почему в уровне мощности 0 эти значения настолько высоко и не выровнены с dmesg? Какова могла быть причина его?

Состояние электропитания корректируется динамично на основе текущей конфигурации GPU. Я подозреваю, что у Вас есть несколько дисплеев, подключенных который, почему часы выше. Динамическое переключение mclk сделано во время вертикального времени гашения обратного хода, таким образом, это может только быть сделано, когда единственный дисплей присоединяется. Когда несколько дисплеев присоединяются, mclk вызывается высоко. Минута sclk уровни / макс. sclk уровни, возможно, также должна быть скорректирована в зависимости от текущих требований.
