Core temperature doesn't show

[crantisz]

I have installed zenpower and zenmonitor, it shows Power and Frequency, but not temperature or fun speed:

I have Ubuntu 19.10, kernel 5.3 AMD Ryzen 3900x Gigabyte x570 UD

[crantisz]

Looks like I have 5.3.0, 5.3.4 needed?

[ocerman]

@crantisz hello, The output is lacking temperature and voltages because it seems like zenmonitor app could not find zenpowers output.

To get zenpower driver working properly it is recommended for zen2 cpus to have kernel 5.3.4+, with older kernels may or may not be working properly.

Can you to post lsmod and sensors output?

Looks like it shows temperature now. Maybe, reboot or blacklist k10temp helps. Now monitor looks like this: Power shows from time to time

[ocerman]

@crantisz yeah, some people reported before that a restart was needed (i will add it into readme). Core/Package power is read from MSR driver and superadmin permissions is usually needed (so without running sudo, the core/package powers are missing)

[hydrian]

Yea. I think it was the reboot. I'm running the 18.04 HWE (Linux Mint) kernel which is currently 5.0.0-37-generic with no problem.
