power reading not working #105

Open doodie opened 5 years ago

doodie commented 5 years ago

everything is working great except power. i believe the power requirements were Sandy Bridge and newer. The proc I have is a Sky Lake.

CentOS Linux release 7.6.1810 (Core) 4.16.8-1.el7.elrepo.x86_64

Intel(R) Xeon(R) CPU E3-1225 v5 @ 3.30GHz

Any ideas on why power option would be "n/a"?

Thanks for issue, Power usage is calculated by reading information from the directory: /sys/class/powercap/intel-rapl/ Do you have access to it?

doodie commented 5 years ago

just checked and that directory does not exist. is there something that i need to install?

is there something that i need to install?

To my knowledge, no. This directory and the information in it should be provided by the kernel.
I know this is not available on Virtual Machines, but since you are getting temperature, I believe this is not your case.
Another thing might be worth trying is running sudo modprobe msr. This should enable the kernel module which accesses the registers on the CPU. (Usually this is not necessary, and I am not sure this will help).

I believe the problem in CentOS, but I am not familiar enough with it.

If you do find a solution, please post it here.

after reading this, found 1 of the 2 parameters in the config and it needs to be enabled. need to do more reading on this first.
