Hi Rob, Would you tell me the CPUIDLE test steps in pm-qa?
As the pm-qa needs to run in bash, and use the "make" tool, but the
Android
only has its own shell, the "make" tool is not available in Android
system.
Why is pm-qa running make? Is it just to load the system?
pm-qa is a test suit for cpuidle, cpufreq, cpuhotplug ... It uses the "make" tool to check the Linux /sys file system.
Thank a lot.
Hi Zach, The limitation of Android system(bash and make) blocks the CPUIDLE too
much.
Kejun, if make is just being used to make the system busy, we have other tools for that. Talk to Amit about some of the commands he integrated for big.LITTLE testing.
BRs, Kejun

Hi Kejun,
Regarding your two questions below:
- Guess the questions on CPUIDLE implementation will be much better
answered by Rob Lee (Cc-ed). 2. The PM WG has tests for their features:

Thanks, Andrey

Hi Andrey,
I am Kejun from Linaro Android team. I got a task to integrate the CPUIDLE to Linaro Android kernel branch from Zach.
I found the CPUIDLE is included in linux-linaro-3.3-2012.03-2 from your email, and merged Snowball CPUIDLE to linaro-android-12.03-release kernel.
I have some questions about how to verify whether this CPUIDLE feature is integrated or not.
- I found that the cpu_do_idle() is executed. But the code in "if () "
won't be executed after Android starting up. And the current is between 380mA ~ 490mA, I thinks when CPUIDLE is working, the current should be more low than 380mA.
static inline int ux500_enter_idle(struct cpuidle_device *dev, struct cpuidle_driver *drv, int
index)
{
.. if (atomic_inc_return(&master) == num_online_cpus()) {
.. }
wfi: cpu_do_idle()
... }
- Is there some method to test the CPUIDLE feature from the Linux
console?
Thanks a lot.
BRs, Kejun.
