Acpi driver in linux

This driver installs ACPI as the idle handler for Linux, and uses ACPI C2 and C3 processor states to save power, on systems that support it. It is required by several flavors of cpufreq Performance-state drivers. Option: ACPI_HOTPLUG_CPU Kernel Versions: (on/off) depends on ACPI_PROCESSOR HOTPLUG_CPU; select ACPI_CONTAINER; default y.

The components of the architecture in-clude (from the top down): • A user interface to the power management and configuration features. • A power management and power policy component (OSPM). 1 • A configuration management component. • ACPI-related device drivers (for example, drivers for the Embedded Controller, SM-.

The ACPI specification is large and unwieldy hence the Linux ACPI driver is a very large and complex ACPI bugs. The AML code allows firmware vendors to interface with the underlying hardware (e.g. Southbridge, Embedded Sanity Checking ACPI Tables.
