Ryzen 7 9700X power consumption readings not shown on monitoring tools

Hi, I recently built a new PC with a Ryzen 7 9700X CPU and it works perfectly fine except for one thing: whenever I launch any monitoring tool, it does not show any info about it's power draw. I tried many of them: mangohud, occt, sensors... you name it. But none of them show anything on that. The only one I found to be working is

aur/rapl-read-ryzen-git

which is ticked as orphaned for starters, and second of all it would be way easier to have it all in one place (i.e. sensors or, even better, mangohud when gaming). Plus, it only gives the readings for half the cores.

Is there any way to fix this? And also, I'm curious to know, why is that?

Thanks in advance to anyone who replies!

https://github.com/flightlessmango/MangoHud

Note: The zenpower3 or zenergy kernel driver must be installed to show the power draw of Ryzen CPUs

Thanks! I missed it. Which one do you suggest using btw? And why are they not shipped together with the kernel if I may ask?

Both of them could refuse to function after new kernel releases. I used zenergy because zenpower3 didn't work when I needed to monitor the power draw.
Check AUR comment section to see if any of them have problems at the moment.

As far as I understand, exposing the energy counters is a potential security vulnerability. That's why they are not shipped together with MangoHud, let alone kernel, user should do it at his own risk.
