Zenpower is Linux kernel driver for reading temperature, voltage(SVI2), current(SVI2) and power(SVI2) for AMD Zen family CPUs.

zenpower's Issues

AMD 8000G series APU support

I found that code is not touched for years. My old 5700G works beautiful with this program but my 8600G CPU.

Different Output of SV12_Core from Zenmonitor

Hello, I'm using Ryzen 5 3600 with Gigabyte B450 AORUS PRO motherboard. I have a conky script displaying the output on my desktop and my SV12_Core stays at 1.4 V constantly (not going down even on 2.5GHz idle). And I installed zenmonitor and I've got different result. In zenmonitor, the CPU Core Voltage (SV12) goes up and down depending on the CPU frequency (1.1 V on idle and 1.4 V on boost). So why is the core voltage displaying differently? Here's a screenshot showing it.

Here's a screencast showing it with watch 0.5 sensors command compared to zenmonitor:

Support for 19h family

Would it be a lot of work to add support for the Zen3 family?
I love zenpower on my 2700x, would be cool if my 5600x would also be supported.

Thanks,

[Help needed] Please provide debug data from zenpower

Hello everyone,
It would be very helpful for me for further development of Zenpower if you can share debug data from zenpower. Zenpower debug data contains raw data from SMN.

If you have latest zenpower driver installed, you can get debug data from file /sys/class/hwmon/hwmon[num]/debug_data or via this bash script

Please also state your CPU, Motherboard and Linux kernel version. Also, please state if you think that Core/SOC values are swapped or incorrect.

Thank you.

//EDIT:
If possible, please post also sensors output sensors zenpower-*

How to enable on Manjaro/Arch

Hi, I've installed this via the AUR on Manjaro, but running
sudo modprobe zenpower as per the README
I get
modprobe: FATAL: Module zenpower not found in directory /lib/modules/5.6.16-1-MANJARO

Speaking of SVI2_P_Core

What does this sensor mean exactly?

It surely doesn't report the correct power consumption because it remains fairly constant (~31W) despite any load, while e.g.

turbostat --quiet --num_iterations 1 --interval 1 --show PkgWatt --Summary

reports the correct values (from 15W to 91W for my Ryzen 7 3700X CPU).

Curious about Ryzen 7 4750U sensors capabilities

Hi,

This is a bit off-topic. I've just installed zenpower and I get it working showing temperatures:

I was wondering if this is all the data I can expect with current kernel and zenpower. For example, temperature and fan readings are not per individual core.

Merged 5.7-rc Patch Doesn't (or at least no longer) works

So, zenpower as a whole is completely broken now on GCC 10.1.0, which was released the other day. It won't even install on LTS kernels. But I downgraded GCC to get this installed, and turns out, it doesn't work for 5.7-rc5, the current rc for 5.7. I noticed someone else had mentioned a patch, which you seem to have merged, but it doesn't work:

cat /var/lib/dkms/zenpower/44.ee05fcf/build/make.log

make: Leaving directory '/usr/lib/modules/5.7.0-rc5-1-tkg-pds/build'

That's an error in zenpower.c, and it seems specifically to do with the new patch.

So, in summation, zenpower is completely broken with GCC 10.1, and with 9.3 it works for other kernels, but not 5.7-rc5 because of something wrong in the patch.

EDIT: Here again is the GCC-caused breakage output:

Investigating Accuracy of Vcore: Comparison with groeck it87

System Specifications

I've been trying to gauge accuracy of Vcore readings compared to groeck's it87 out of tree module, & I've logged my results of Vcore at idle versus load with both. Simulated load was done using mprime -t. My system is set to 1.275V Vcore in the BIOS.

Here are my findings:

Idle           Load      Measure
--------------------------------
1.257V       |  1.25V   |  zenpower
1.243-1.254V |  1.243V  |  it87

I've been wondering now which method is more accurate. I understand it87 uses a variety of I/O chips which vary depending on motherboard manufacturer. After perusing your code, I noticed no reliance on such dodgy I/O chips. In your opinion, which do you think is more accurate & how would one devise which method of measurement is the most accurate. it87 seems dead in terms of development.

Anyone elses' comparisons would be a welcome addition here.

Better support for building on Arch

I built a PKGBUILD for Arch Linux https://aur.archlinux.org/packages/zenpower-dkms-git/

To make it easy, I simply copied it87's Makefile and edited it a bit. It's fairly similar to your Makefile but has a bit better support for some platforms. Feel free to merge it with yours :)

Multi-CPU support

I believe @harrykipper 's system have 2x epyc #12 (comment), but SVI2 sensors are displayed only for 1. CPU

[Question] Are you looking to get this mainlined?

Thanks for providing this! Zen sensor support has been quite bad in Linux and this driver is certainly appreciated.

But seems to me that this driver should probably land in the kernel itself I wonder if you are trying to get it mainlined. Are you?

Does anyone support or plan to support the Ryzen 7000 series? If so, let me know! I'm interested in that.

Is this project dead?

Considering the issues, commits, Zen 4 support and overall activity on the project is seems abandoned.
Is the anyone maintaining this repository or any plans to get it updated?

Zen power can't report each core's temperature on R9 3950X.

My mainboard is ASUS PRO WS X570 ACE, CPU is R9 3950X. I have compiled zenpower (on Linux kernel v5.5.7). But it only shows Tccd, Tdie, Tctl. Each core's temperature doesn't show up in sensors application.

Upstreaming or merging with k10temp?

Did you consider merging it with k10temp? There is no need to limit the later to temperature only.

Missing license.

Hey,

I'm adding zenpower to my Gentoo overlay (repository) and there is no license. As kernel module I think this should be under GPL license terms.

Please consider adding license in near future.

Have to reinstall to see voltages, etc. after reboot in zenmonitor

Not sure what the reason for this may be. I will keep trying to debug.

TLP + auto-cpufreq

Just bought my new Thinkpad T14 AMD and immediately started to tune it.

There are a lot of manuals on internet how to improve battery life. I ended up with tlp+auto-cpufreq
But... Kernel 5.9 released, where many power management improvements were done.

I don't have so much experience with hw tuning, so I would like to ask: is it worth to use tlp+auto-cpufreq or system power management is more effective?

Maybe add answer to this question to README/WIKI?

Can't compile latest version

Hi,

I can not compile the latest version of zenpower on my system.
0.1.5 works, but 0.1.6 & 0.1.7 failed.

cpu power

Hello to all.

happy new year to come .

here it is : I am under debian sid kernel 6.0.0-6-amd64

i noticed (at least, it seems to me) that the display of the cpu power (ryzen 9 3900x, asus prime x570 pro) in lm-sensors does not work anymore.
the voltages have also disappeared.
only the temperatures and the speed of the cpu fan remain.

Do you have any explanation for this phenomenon?
and solutions ?

in my games, with mangohud, I would have liked to display also the cpu power.
but this data is constantly displayed at zero.

waiting to read you ...
friendly, dany .

p.s.: on request, I can give you more information, of course.

Wrong info shows on Ryzen 3000

First, thank you for creating this. Looking forward to new updates

Now for the issue:
I'm using Ryzen 3900x on top of Ubuntu 19.04 (Pop OS) and the numbers the sensor is showing are not correct.

This is what I'm getting from "sensors" command

SVI2_Core & SVI2_SoC mixed up on ASRock X470 Taichi

My Core and SoC seem to be the wrong way around; this is on a 3700x and ASRock X470 Taichi. It was correct when the CPU was in my old Asus X370 Prime board but on ASRock X470 Taichi it appears swapped. I have re-run sensors-detect etc. Unsure if I simply need to just rename some labels? If that's the case close the issue.

I get the following output from lm_sensors on my Ryzen 7 3700x:

Do you have any documentation to help me test/code to get this working?

SVI2_C_SoC Current is 0 on threadripper 2920x

zenpower reports current is 0. The SoC voltage also seems very low as well.
