Subject: [RFC][PATCH] cpufreq: Support of Energy Performance preference
Date: Tue, 15 Nov 2016 14:59:42 -0800 [thread overview]
Message-ID: <1479250783-74336-1-git-send-email-srinivas.pandruvada@linux.intel.com> (raw)
This change allows user to provide hints to P-State selection algorithm
to be more more performance centric or more energy centric.
Even if this change only impacts intel_pstate driver, this change is
submitted as RFC to check if we need a generic method in cpufreq to
support such configuration.
If other SoCs don't allow such configuration, then this change can be only
in intel_pstate using local cpufreq attributes as it is implemented now.
