Linux 3.13 Gets A Second Helping Of Power Management

Linux Kernel

A second pull request has been submitted for the Linux 3.13 kernel that provides further updates to the often less than desirable ACPI and power management code.

Submitted (and pulled) two weeks ago were already big ACPI and PM updates for this next Linux kernel release. However, Rafael Wysocki has now sent in a second ACPI/PM update for Linux 3.13 that's queued up some more changes then and right ahead of the 3.13-rc1 tagging.

Now most of the work in this second Git pull are for fixes, but there's also new hardware support and other changes as part of the update. Among the noteworthy changes include fixing the CPUfreq conservative governor, new processor IDs for intel_idle and Intel TurboStat, new device IDs for the ACPI Low-Power Subsystem (LPSS) driver, an ACPI-based PCI Hot-Plug (ACPIPHP) clean-up, and various other fixes.

The second ACPI/PM pull request for Linux 3.13 can be found via the Indiana kernel mailing list. If power management code doesn't get you excited, there's plenty of other groundbreaking features in Linux 3.13.
