The Linux 3.12 kernel will feature improvements to ACPI and power management in general thanks to recent developments.

The ACPI/PM pull request was merged on Tuesday for the Linux 3.12 kernel merge window. Some of the notable highlights include:

- The ACPI PCI hotplug subsystem has been reworked and now includes support for Intel Thunderbolt on systems that use ACPI for signalling of Thunderbolt hot-plug events.

- ACPI core code clean-ups.

- ACPICA was updated to 20130725 and includes fixes, new support, and other improvements.

- ACPI and Xen should now work better to reduce hardware sleep work.

- ACPI fixes.

- The cpufreq on demand governor should now choose target frequencies proportionally to load.

- Various other ACPI and power management improvements.

More details can be learned from the ACPI/PM Linux 3.12 pull.
