Subject: acpi_idle and max_cpus
Date: Fri, 15 Jun 2012 17:28:31 +0200 [thread overview]
Message-ID: <4FDB549F.1020002@linaro.org> (raw)
Hi all,
I have a dual core Intel T9500.
I boot the cpu with the acpi_idle driver and intel_idle enabled in the
config.
The kernel is booted with maxcpus=1.
After the system has boot, I put cpu1 online via sysfs.
But I don't see any 'cpuidle' directory in the cpu's sysfs entry:
/sys/devices/system/cpu/cpu1/cpuidle (?)
When I look at the code I see the notifier is present for hotplug in
processor_driver.c and the cpuidle intel init routine should be called
there.
I am wondering is it a bug or an expected behavior ?
Thanks
-- Daniel
