Hi!

I test with below two cpu to test: - Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz - Intel(R) Atom(TM) CPU S1240 @ 1.60GHz

With below action: make -C cpuidle cpuidle_killer make -C cpuhotplug run_tests

With Xeon, 04/04/06 failed:

With Atom cpu, all passed.

I google this cpu feather but do not get detail info about it. I wonder the difference between those two cpus and can enable those tests on Xeon if possible.

Thanks Xiang
