From 6be264986152c498562f26b15ed73c70aa37ce48 Mon Sep 17 00:00:00 2001 From: Dirk Brandewie Date: Fri, 15 Feb 2013 22:55:10 +0100 Subject: cpufreq / intel_pstate: Add kernel command line option disable intel_pstate. When intel_pstate is configured into the kernel it will become the preferred scaling driver for processors that it supports. Allow the user to override this by adding: intel_pstate=disable on the kernel command line. Signed-off-by: Dirk Brandewie Signed-off-by: Rafael J.
