From f4e78a2d9fde8ea56303bd06076911b63fd27e68 Mon Sep 17 00:00:00 2001 From: Vincent Guittot Date: Thu, 25 Aug 2011 08:31:20 +0200 Subject: [PATCH] [CPUFREQ] ARM: ux500: send cpufreq notification for all cpus The same clock is used for all cpus so we must notify the frequency change for each one in order to update the configuration of all twd clockevents. change since V1: * use policy->cpus instead of cpu_online_mask Signed-off-by: Vincent Guittot Signed-off-by: Dave Jones --- drivers/cpufreq/db8500-cpufreq.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/drivers/cpufreq/db8500-cpufreq.c b/drivers/cpufreq/db8500-cpufreq.c index d90456a809f9..e0acaceca57d 100644 --- a/drivers/cpufreq/db8500-cpufreq.c +++ b/drivers/cpufreq/db8500-cpufreq.c @@ -72,13 +72,13 @@ static int db8500_cpufreq_target(struct cpufreq_policy *policy, freqs.old = policy->cur; freqs.new = freq_table[idx].frequency; - freqs.cpu = policy->cpu; if (freqs.old == freqs.new) return 0; /* pre-change notification */ - cpufreq_notify_transition(&freqs, CPUFREQ_PRECHANGE); + for_each_cpu(freqs.cpu, policy->cpus) + cpufreq_notify_transition(&freqs, CPUFREQ_PRECHANGE); /* request the PRCM unit for opp change */ if (prcmu_set_arm_opp(idx2opp[idx])) { @@ -87,7 +87,8 @@ static int db8500_cpufreq_target(struct cpufreq_policy *policy, } /* post change notification */ - cpufreq_notify_transition(&freqs, CPUFREQ_POSTCHANGE); + for_each_cpu(freqs.cpu, policy->cpus) + cpufreq_notify_transition(&freqs, CPUFREQ_POSTCHANGE); return 0; } -- 2.39.5
