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?
Thanks
Xiang

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.

cputopology_04.0: no cpus directory present... skip <===

The skip reason is that there is not /sys/firmware/devicetree/base/cpus.
But i do not find how to enable this.
Could you help me?

I check cpus and make sure two cpus can support cpufreq refer to
https://www.kernel.org/doc/Documentation/cpu-freq/user-guide.txt.
Do i miss something important or this subtest can not all pass with
Intel cpu?

Hi,
ci.linaro.org is currently unresponsive and the service requires to be
restarted.
It's an unscheduled reboot, sorry for the short notice and inconvenience.
Cheers,
