The ACPI and power management updates for the Linux 3.14 kernel have a wide range of changes, including updates to Intel's new P-State CPUfreq driver, various fixes, and other CPUfreq improvements.

Rafael J. Wysocki submitted the feature pull request for the ACPI and power management areas of the Linux kernel on Monday for the 3.14 merge window. As usual, there's a whole lot of changes scattered throughout.

Among the user-facing work are new Win8 OSI blacklist entries, many ACPI fixes, Intel P-State driver updates, Intel P-State support for Atom "Bay Trail" SoCs, AMD PowerNow-K6 fixes, support for hibernation APM events, CPU idle clean-ups, various CPUfreq driver fixes, a hibernation fix, PM core fixes, and various other fixes and clean-ups.

The Linux 3.14 kernel will also have the generic CPU Boost/Turbo support for CPUfreq.

For those interested in more details on all of the power management related work for the Linux 3.14 kernel, check out the mailing list pull request.
