Linux 4.7 Adds PMC Driver For Intel Core SoCs

Written by Michael Larabel in Intel on 28 May 2016 at 10:05 AM EDT. Add A Comment

One of the last pull requests to cover for the Linux 4.7 merge window is Darren Hart's platform-drivers-x86 updates.

A new driver for the platform-drivers-x86 area is a PMC driver for Intel Core SoCs. This Power Management Controller (PMC) driver is for exposing debugging capabilities and other functionality of the hardware's PMC. So far this Intel PMC x86 driver just exposes a SLP_S0_RESIDENCY counter.

Details on this Intel PMC Core SoC driver can be found via the Git commit mainlining this new code.

In addition to the Intel PMC driver, there is support for the radio LED in the Fujitsu laptop code, corrections in the ASUS laptop code, and other minor changes. All the details via this pull request.
