From f4a5d17efec95ee74113df62943494a2197c8bae Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Sat, 16 Nov 2013 14:39:22 +0100 Subject: [PATCH] tools: cpupower: fix wrong err msg not supported vs not available idlestates in sysfs are counted from 0. This fixes a wrong error message. Current behavior on a machine with 4 sleep states is: cpupower idle-set -e 4 Idlestate 4 enabled on CPU 0 -----Wrong--------------------- cpupower idle-set -e 5 Idlestate enabling not supported by kernel -----Must and now will be ----- cpupower idle-set -e 5 Idlestate 6 not available on CPU 0 ------------------------------- cpupower idle-set -e 6 Idlestate 6 not available on CPU 0 Signed-off-by: Thomas Renninger Signed-off-by: Rafael J.
