Subject: [PATCH 0/2] intel_pstate: Add support for hardware managed P states (HWP)
Date: Thu,  6 Nov 2014 09:40:45 -0800	[thread overview]
Message-ID: <1415295647-4063-1-git-send-email-dirk.j.brandewie@intel.com> (raw)

From: Dirk Brandewie <dirk.j.brandewie@intel.com>

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.
