From c81147483e525e4a471d581877d7d634591246e1 Mon Sep 17 00:00:00 2001 From: Fenghua Yu Date: Tue, 21 May 2013 15:35:16 -0400 Subject: [PATCH] x86 thermal: Delete power-limit-notification console messages Package power limits are common on some systems under some conditions -- so printing console messages when limits are reached causes unnecessary customer concern and support calls. Note that even with these console messages gone, the events can still be observed via system counters: $ grep TRM /proc/interrupts Shows total thermal interrupts, which includes both power limit notifications and thermal throttling interrupts. $ grep . /sys/devices/system/cpu/cpu*/thermal_throttle/* Will show what caused those interrupts, core and package throttling and power limit notifications. https://bugzilla.kernel.org/show_bug.cgi?id=36182 Signed-off-by: Fenghua Yu Signed-off-by: Len Brown Signed-off-by: Tony Luck --- arch/x86/kernel/cpu/mcheck/therm_throt.c | 9 --------- 1 file changed, 9 deletions(-) diff --git a/arch/x86/kernel/cpu/mcheck/therm_throt.c b/arch/x86/kernel/cpu/mcheck/therm_throt.c index 47a1870..68fa8904 100644 --- a/arch/x86/kernel/cpu/mcheck/therm_throt.c +++ b/arch/x86/kernel/cpu/mcheck/therm_throt.c @@ -181,11 +181,6 @@ static int therm_throt_process(bool new_event, int event, int level) this_cpu, level == CORE_LEVEL ?
