Частота процессора Intel Core i7-8550U падает при высоких нагрузках в Ubuntu 20.04
Я установил Ubuntu 20.04 и имею следующий процессор:
grep -E '^model name|^cpu MHz' /proc/cpuinfo
model name : Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz
cpu MHz : 3000.025

cpu MHz : 2989.114
model name : Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz
cpu MHz : 3001.278
Я использую следующую команду для установки регулятора и диапазона частот:
sudo cpupower frequency-set --governor performance --min 2600000 --max 3000000
И следующую команду, чтобы проверить это:
cpupower frequency-info
analyzing CPU 0:
driver: intel_pstate
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: Cannot determine or is not supported.
hardware limits: 400 MHz - 4.00 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 2.60 GHz and 3.00 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 3.00 GHz (asserted by call to kernel)
boost state support:
Supported: yes
Active: yes
Текущая частота указана диапазон, это верно в условиях холостого хода.
Однако после запуска программы (gmic), загружающей процессор, текущая частота падает ниже указанного диапазона:
cpupower frequency-info
analyzing CPU 0:
driver: intel_pstate
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: Cannot determine or is not supported.
hardware limits: 400 MHz - 4.00 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 2.60 GHz and 3.00 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 1.80 GHz (asserted by call to kernel)
boost state support:
Supported: yes
Active: yes
Под Windows я запускаю то же приложение и добиваюсь гораздо более высокой производительности. В условиях холостого хода частота составляет около 1 ГГц, а под нагрузкой частота увеличивается до 2,6 ГГц. Так что я не думаю, что это проблема, связанная с оборудованием или BIOS.
Я перезагрузил Ubuntu, чтобы отменить изменения частоты процессора (так что они снова являются значениями по умолчанию). Я буду отслеживать частоту процессора и другую важную информацию с помощью утилиты turbostat .
Вот выходные данные турбостата:

Похоже, Ubuntu снижает энергопотребление процессора. . Поскольку невозможно оставаться при высокой нагрузке и в заданном частотном диапазоне (при снижении энергопотребления), частота падает, чтобы удовлетворить ограничение по мощности.
Теперь я снова перезагружаю Ubuntu, поэтому частота процессора возвращается к значениям по умолчанию.
Я действительно запускал Thermald:
sudo service thermald status

Для сбора следующих данных:

3. params in /sys/devices/system/cpu/intel_pstate directory
4. params in /sys/class/powercap/intel-rapl/intel-rapl:0 directory
5. scaling limits in /sys/devices/system/cpu/cpu*/cpufreq directory

<<< see log below in my next post, because post size is limited >>>
Мой ноутбук постоянно подключен к розетке, поэтому ограничений по мощности, связанных с питанием от аккумулятора, возникать не должно.
Вы знаете, как отключить ограничение мощности процессора в Ubuntu? Таким образом, процессор будет потреблять максимальное количество энергии, необходимое для работы на высокой частоте. Будем признательны за любые комментарии. Спасибо.

Также я нашел bluetooth erros в выводе dmesg:
[ 7.747559] Bluetooth: hci0: command 0xfc05 tx timeout
[ 7.747568] Bluetooth: hci0: Reading Intel version information failed (-110)
[ 7.747569] Bluetooth: hci0: Intel Read version failed (-110)
Я вижу, что включен тепловой мониторинг процессора:
[ 0.165359] mce: CPU0: Thermal monitoring enabled (TM1)
и эта странная строка:
[ 6.139480] thermal thermal_zone10: failed to read out thermal zone (-61)

версия микрокода процессора на Windows:
reg query HKLM\HARDWARE\DESCRIPTION\System\CentralProcessor\0 | find "Update Revision"
Update Revision REG_BINARY 00000000B4000000
Previous Update Revision REG_BINARY 0000000084000000
Update Revision является текущей версией микрокода. Предыдущая версия является микрокодовой версией в BIOS.
Утилита Intel Processor Identification Utility на Windows показывает, что Версия процессора действительно B4. Так что на самом деле Windows работала со старой версией микрокода.
Однако, дросселирование мощности все еще происходит, после понижения микрокода на Ubuntu с E0 до B4. Таким образом, багги микрокод здесь не является проблемой.
Я удалил intel_powerclamp модуль (на всякий случай):
sudo rmmod intel_powerclamp
В выводе top я вижу idle_inject процессы для каждого ядра процессора:
idle_inject/0
idle_inject/1
idle_inject/2
idle_inject/3
Это Idle Injection Framework (CONFIG_IDLE_INJECT), который был представлен в ядре linux 4. 19
Оно предназначено для питания системы, так что, возможно, оно дает такое падение мощности?

Читатели: проявите терпение, мы надеемся, что в конечном итоге вопрос и ответ будут сведены к краткому содержанию.
Из всей предоставленной информации это наиболее актуально:

Указывая, что процессор в настоящее время троттлинг из-за ограничения мощности пакета процессора №1, в то время как процессор не приближается к пределу мощности пакета №1, по крайней мере, если мы верим тому, что говорит нам турбостат.
При ручном декодировании MSR 0x64F, помимо прочего, устанавливается бит 10. Из 64-ia-32-architecture-software-developer-manual-325462:
Состояние PL1 ограничения мощности на уровне платформы / пакета (R0) Когда установлено, частота снижается до уровня ниже запрашиваемой операционной системы. к PL1 с ограничением мощности на уровне пакета / платформы.
Все остальные биты - это биты журнала с фиксацией, которые сейчас не актуальны.
RAPL_POWER_UNIT MSR (0x606) дал 0x000a0e03, что означает правильное декодирование до 0,125 Вт на бит.
MSR PKG_POWER_LIMIT (0x610) дал 0x42016000dc8090. Давайте вручную расшифруем ограничение мощности 1 часть. Биты 14: 0 определяют предел, или 90h или 144 десятичных знаков. Раз .125 = 18 Вт, как и ожидалось. Бит 15 равен 1, поэтому он включен.
Итак, что-то не так, и процессор, похоже, ведет себя не так, как должен.
Может ли это быть как-то связано с необычно высоким пределом пакета процессора №2? Обычно он устанавливается примерно в 1,25 раза превышающем предел мощности №1. такое высокое значение, скорее всего, вызовет проблемы.
РЕДАКТИРОВАТЬ 1: возврат к MSR 0x64F, другие зафиксированные биты указывают на температуру, ПРОХОТ (всегда плохой) и «ДРУГИЕ» условия, которые имели место ранее.Я бы снизил предел мощности 2 с 44 до примерно 22 или 23 Вт. Также предлагаем внимательно посмотреть на это, исходя из низкой частоты процессора. Например, установите очень низкую максимальную частоту процессора:
echo 10 | sudo tee /sys/devices/system/cpu/intel_pstate/max_perf_pct
, а затем примените большую нагрузку, все время наблюдая с помощью турбостата и наблюдая MSR 0x64f одновременно в двух окнах терминала. Постепенно увеличивайте частоту процессора:
echo 15 | sudo tee /sys/devices/system/cpu/intel_pstate/max_perf_pct
echo 20 | sudo tee /sys/devices/system/cpu/intel_pstate/max_perf_pct
echo 25 | sudo tee /sys/devices/system/cpu/intel_pstate/max_perf_pct
...
, пока она не снизится.
РЕДАКТИРОВАТЬ 2: Вероятно, задействована модуляция тактовой частоты, если это так вероятно из BIOS и, вероятно, из-за чрезвычайно высокой настройки ограничения мощности №2. Способ узнать - прочитать MSR 0x19A во время нечетного дросселирования. Выполните sudo rdmsr -a 0x19a . Пример:

... apply load and start turbstat ...
root@s19:/home/doug# wrmsr -a 0x19a 0 <<< disable CM
Ожидаемый вопрос: Тогда почему он не исправляется до тех пор, пока не будет снята нагрузка.
Ответ: Из-за суровых условий, в которых в первую очередь потребовалась Модуляция часов, она не удаляется, пока все не станет действительно спокойным и крутым. На некоторых компьютерах он никогда не сбрасывается.
