Subject: spurious bL cpufreq driver messages
Date: Fri, 17 May 2013 14:36:28 -0500 [thread overview]
Message-ID: <519686BC.3090101@gmail.com> (raw)
The bL cpufreq driver appears to collide with the cpufreq-cpu0 driver.
There doesn't appear to be a functional problem, but just spurious
prints which indicate it is trying to do something. I think it needs
better checking whether the chip is actually multi-cluster. This is what
I get when I hotplug cpus:
[ 909.372319] CPU1: Booted secondary processor
[ 909.372616] cpu cpu1: get_cluster_clk_and_freq_table: init_opp_table
failed, cpu: 1, err: -61
[ 909.385411] cpu cpu1: get_cluster_clk_and_freq_table: Failed to get
data for cluster: 9
[ 909.394161] CPU2: shutdown
