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
