Hi!

I use a kvm based on Intel(R) Atom(TM) CPU S1240 @ 1.60GHz Atom cpu to test. The cmd which create vm is qemu-system-x86_64 -enable-kvm -cpu host.

### ### cputopology_04: ### Test capacity calculation (this is based on the algorithm in arch/arm/kernel/topology.c), make sure that the information in /sys/firmware/devicetree/base/cpus corresponds to that reported by the kernel log. ### https://wiki.linaro.org/WorkingGroups/PowerManagement/Resources/TestSuite/Pm... ### cputopology_04.0: no cpus directory present... skip <===

cputopology_04: 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?

Thanks Xiang
