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.

Kejun,
Please submit to patch to linaro-dev and Hongbo Zhang and we'll consider taking it in.

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.
Can you remove make and update the test to work against what Android ships with?
I don't think this is a good idea. As the pm-qa is still updating, developing a new one to test cpuidle means two parallel branches, it is wasting our resource.
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.

Kejun,
Would you prepare what you have for upload to android.git.linaro.org? We can create a new git at, test/linaro/pm/pm-qa. Would you also update the test spreadsheet with the steps to run the builds?

Hi Zach, I think I should wait for the delivery with complete CPUIDLE test cases. The CPUIDLE in pm-qa just has only one test case the "cpuidle_01.sh" now. I don't know what issue we will meet when the complete CPUIDLE arrived. Even my modification couldn't be used at that time. And we need some new method to make it work on Android.
