[PATCH 0/2] intel_pstate: Add support for hardware managed P states (HWP)

From: dirk . brandewie
Date: Thu Nov 06 2014 - 12:41:03 EST


From: Dirk Brandewie <dirk.j.brandewie@xxxxxxxxx>

This patch set adds support for HWP. When HWP is enabled the CPU will
do P state autonomously and intel_pstate simply provides an interface
to forward user preferences to the CPU while maintaining the
interfaces required by the cpufreq core.

x86: Add support for Intel HWP feature detection.
