Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring.

2022年12月10日 · 为了开发 ACPI，需要使用 ACPI Source Language(ASL) 来进行编程，使用 iasl 编译成 ACPI 表以后，由操作系统进行解释执行。 推荐阅读一个比较好的 ASL 教程： ACPI Source Language (ASL) Tutorial 。

2024年8月11日 · # Getting started with ACPI # A quick explainer on ACPI. So what are DSDTs and SSDTs? Well, these are tables present in your firmware that outline hardware devices like USB controllers, CPU threads, embedded controllers, system clocks and such.

The Windows ACPI driver, Acpi.sys, is an inbox component of the Windows operating system. The responsibilities of Acpi.sys include support for power management and Plug and Play (PnP) device enumeration. On hardware platforms that have an ACPI BIOS, the HAL causes Acpi.sys to be loaded during system startup at the base of the device tree. Acpi ...

ACPI classifies hardware into two categories: Fixed or Generic. Hardware that falls within the fixed category meets the programming and behavior specifications of ACPI. Hardware that falls within the generic category has a wide degree of flexibility in its implementation.

The Advanced Configuration and Power Interface (ACPI) specification was developed to establish industry common interfaces enabling robust operating system (OS)-directed motherboard device configuration and power management of both devices and entire systems.

2025年1月13日 · Advanced Configuration and Power Interface（ACPI）的开发是为了建立通用工业接口，从而实现针对操作系统OS的主板设备配置和整个系统的电源管理。 ACPI是面向操作系统的配置和电源管理（OSPM）中的重要元素。 OSPM/ACPI提倡将系统空闲的设备转为低功耗来节约能源。 有必要将 电源管理 移到操作系统中，并在操作系统和硬件设备之间使用抽象接口（ACPI）来实现这个目标，因为ACPI是抽象的，操作系统可以从硬件设备中独立发展，硬件 …

ACPI defines a standard hardware and software communications interface between an OS bus driver and an SMBus Controller. This allows any OS to provide a standard bus driver that can directly communicate with SMBus devices in the system. This in turn enables the OEM to provide platform features that the OS and applications can use.

2024年9月26日 · The ACPI 5.0 specification defines many device types to represent and control typical platform features. For example, ACPI defines a power button, a sleep button, and system indicators. For SoC-based platforms, Windows provides built-in drivers to support the ACPI-defined devices that are described in this article.
