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.
BRs, Kejun
