ACPI (Advanced Configuration and Power Management Interface) is a power management system that is part of the BIOS.

Не обходимо включить следующие опции ядра для ACPI:

Ядро 
Power management and ACPI options  --->
    [*] Power Management support
        [*] ACPI (Advanced Configuration and Power Interface) Support  --->
Optional drivers
Option Module Recommend Description
Deprecated /proc/acpi files - No Creates deprecated files in the procfs filesystem, which are now replaced by files in the sysfs filesystem.
Deprecated power /proc/acpi directories - No Creates deprecated files in the procfs filesystem, which are now replaced by files in the sysfs filesystem.
EC read/write access through /sys/kernel/debug/ec ec-debugfs No Debug interface to the Embedded Controller.
Deprecated /proc/acpi/event support - No Creates deprecated files in the procfs filesystem, which are now replaced by the input layer or netlink events.
AC Adapter ac Laptops Creates files to tell, if your system is connected to AC.
Battery battery Laptops Creates files to tell, if your system is powered by a battery.
Button button - Handles events on the power, sleep, and lid buttons.
Video video - Supports basic operations for graphics adapters.
Fan fan - Supports ACPI fan devices, allowing user-mode applications to perform basic fan control (on, off, status).
Dock dock - Supports ACPI-controlled docking stations and removable drive bays, see the acpi dock article.
Processor processor - Installs ACPI as the idle handler for Linux and uses ACPI C2 and C3 processor states to save power.
Processor Aggregator processor-aggregator - ACPI 4.0 function to perform specific processor configuration and control.
Thermal Zone thermal Yes Supports ACPI thermal zones to protect your processor against overheating.
NUMA support - -
Debug Statements - No
PCI slot detection driver pci-slot No Helps to correlate PCI bus addresses with physical slots
Container and Module Devices container - Supports ACPI Container and Module devices to hotplug nodes, CPUs, and memory.
Smart Battery System sbs, sbshc - Supports another type of access to battery information, found on some laptops.
Hardware Error Device hed - Supports the Hardware Error Device, which is used to report some hardware errors.
Allow ACPI methods to be inserted/replaced at run time custom-method No
ACPI Platform Error Interface (APEI) - - APEI allows to report errors (for example from the chipset) to the operating system.

Emerge

Desktop environments react on the common events generated by ACPI. If a desktop environment is not installed or to have the system react on special events the ACPI package can be installed. Install the sys-power/acpid package:

root #emerge --ask sys-power/acpid

USE-флаги

Некоторые пакеты знают о глобальном USE-флаге acpi. На данный момент нет каких-либо use-флагов для sys-power/acpid.

SELinux

Чтобы acpid мог выключить SELinux подсистему, убедитесь, что пакет sec-policy/selinux-shutdown установлен и испольняемый файл /sbin/shutdown перемаркирован:

root #emerge --ask sec-policy/selinux-shutdown

Конфигурация

Скрипты, находящиеся в /etc/acpi пределяют как система должна реаргировать на события ACPI. Они могут быть отредактированы под потребности пользователя.

Сервисы

OpenRC

Сервис acpid теперь может быть запущен. В случае использования OpenRC запустите:

root #/etc/init.d/acpid start

Добавьте сервис acpid на уровень запуска по умолчанию, чтобы сервис он запускался во время загрузки:

root #rc-update add acpid default

systemd

В случае если systemd используется как система инициализцации, включите сервис acpid для запуска во время загрузки запустив:

root #systemctl enable acpid.service

Чтобы запустить сервсис сейчас:

root #systemctl start acpid.service

Расширенные примеры

Настройки ACPI по умолчанию могут быть удовлетворительными для некоторых пользователей, тем не менее небольшие дополнительные настройки могут быть необходимы чтобы демон acpid правильно обрабатывал некоторые базовые ACPI события (подключение/отключение источника бесперебойного питания, мультимедия кнопки и так далее).

Modifications can be make to /etc/acpi/default.sh along with /etc/acpi/events/default if necessary. Why not create a complicated setup that makes use of the /etc/acpi/actions and /etc/acpi/events capabilities? Simply put scripts and event files in those locations for advanced usage.

A basic default.sh file will probably be enough for most users, however the following is an example of what could be done using default.sh:

Заметка
Notice that the above script is compatible with ALSA and OSS, so no extra actions are needed when switching OSS from ALSA or the opposite. Do not hesitate to edit the script!
Заметка
The above script also makes use of a power management profile using hprofile. Refer to the hprofile article for more information.
