From 553953453b4b64fbccba31691257d006cee36613 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 22 Mar 2017 23:53:54 +0100 Subject: [PATCH] cpufreq: intel_pstate: Use load-based P-state selection more widely 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").
