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 cputopology run_tests

Both cpu fail with cputopology_04: cputopology_04.0: no cpus directory present... skip

cputopology_04: skip

I check the code: if ! [ -d /sys/firmware/devicetree/base/cpus ]; then log_skip "no cpus directory present" return fi

But i do not really know what this dir mean and do not get detail info fron google.

Is that only enable on specified type of cpu? or i miss some config about it?

The /sys/firmware/devicetree/base directory shows the device tree structure on ARM, for example, but device tree isn't supported on x86 that I am aware of.

Thanks
