From a8e6da093ea8642b1320fb5d64134366f2a8d0ac Mon Sep 17 00:00:00 2001 From: Vaidyanathan Srinivasan Date: Mon, 1 Mar 2010 02:58:23 +0000 Subject: powerpc: Reduce printk from pseries_mach_cpu_die() Remove debug printks in pseries_mach_cpu_die(). These are noisy at runtime. Traceevents can be added to instrument this section of code. The following KERN_INFO printks are removed: cpu 62 (hwid 62) returned from cede. Decrementer value = b2802fff Timebase value = 2fa8f95035f4a cpu 62 (hwid 62) got prodded to go online cpu 58 (hwid 58) ceding for offline with hint 2 Signed-off-by: Vaidyanathan Srinivasan Cc: Gautham R Shenoy Signed-off-by: Benjamin Herrenschmidt --- arch/powerpc/platforms/pseries/hotplug-cpu.c | 11 ----------- 1 file changed, 11 deletions(-) (limited to 'arch/powerpc') diff --git a/arch/powerpc/platforms/pseries/hotplug-cpu.c b/arch/powerpc/platforms/pseries/hotplug-cpu.c index fefb7f84800b..a8e1d5d17a28 100644 --- a/arch/powerpc/platforms/pseries/hotplug-cpu.c +++ b/arch/powerpc/platforms/pseries/hotplug-cpu.c @@ -122,21 +122,10 @@ static void pseries_mach_cpu_die(void) if (!get_lppaca()->shared_proc) get_lppaca()->donate_dedicated_cpu = 1; - printk(KERN_INFO - "cpu %u (hwid %u) ceding for offline with hint %d\n", - cpu, hwcpu, cede_latency_hint); while (get_preferred_offline_state(cpu) == CPU_STATE_INACTIVE) { extended_cede_processor(cede_latency_hint); - printk(KERN_INFO "cpu %u (hwid %u) returned from cede.\n", - cpu, hwcpu); - printk(KERN_INFO - "Decrementer value = %x Timebase value = %llx\n", - get_dec(), get_tb()); } - printk(KERN_INFO "cpu %u (hwid %u) got prodded to go online\n", - cpu, hwcpu); - if (!get_lppaca()->shared_proc) get_lppaca()->donate_dedicated_cpu = 0; get_lppaca()->idle = 0; -- cgit v1.2.3
