ACPICA. Most of these are still works in progress. Support exists for: - Fixed feature and control method power, lid and sleep buttons. - Detection of ISA PnP devices using ACPI namespace. - Detection of PCI root busses using ACPI namespace. - CPU throttling and sleep states (incomplete) - Thermal monitoring and cooling control (incomplete) - Interface to platform embedded controllers (mostly complete) - ACPI timer (incomplete) - Simple userland control of sleep states. - Shutdown and poweroff.
