Subject: [PATCH 2/5] cpufreq: intel_pstate: Use load-based P-state selection more widely
Date: Wed, 22 Mar 2017 23:53:54 +0100	[thread overview]
Message-ID: <135486514.0oxrMEpPDc@aspire.rjw.lan> (raw)
In-Reply-To: <2025489.DxMTzKos7o@aspire.rjw.lan>

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Extend the set of systems for which intel_pstate will use the
"powersave" P-state selection algorithm based on CPU load in the
active mode by systems with ACPI preferred profile set to "tablet",
"appliance PC", "desktop", or "workstation" (ie. everything with a
specified preferred profile that is not a "server").
