ACPI(Advanced Configuration and Power Interface), is a Power Management and configuration standard allowing the operating system to control the amount of power each device is given (allowing it to put certain devices on standby or power-off for example). It is also used to control and/or check thermal zones (temperature sensors, fan speeds, etc), battery levels, PCI IRQ routing, CPUs, NUMA domains and many other things.
This series adds ACPI support to QEMU targets. Currently, the Linux kernel graphics console does not work with this series. Changes in v6: - Incoporated Bin's review comments.
