AMD AM5 Temp Reporting Support

[phantomsfbw]

Any chance we will see support for Temp reporting for AM5 systems?d

Thanks!

this would be built in to FreeBSD. Are you unable to read any temp from AM5? have you looked at FreeBSD forums on this?

I am running the latest OPNSense on an AMD 7900X as a homelab bench project. It is zippy compared to the Intel I3 have been using.  I have been trying to anticipate the newer firewall options that tend to slow traffic.  Overkill sure, but I had a spare to play with.  Did find one FreeBSD thread that discussed Ryzen 7 support from May 2023.  Mostly laptops in the discussion.  Folks were having a hard time just getting the OS to install.  One noted temps did not work, and I noticed on my workbench today, a similar instance of no temp support, even with the old AMD sensor selected.  Was hoping a forthcoming FreeBSD 14 shift in OPNSense might, just might get it sorted.  I did experience the trials and tribulations of other linux distros getting up to speed with the new hardware in late 2022 and 2023, but I don't typically track BSD distros. Did a spin of PfSense this evening on the CPU, and it has the newer FreeBSD foundation, and no temp joy there in that instance. I'm sure the builders will get around to it at some point.

What did you select under System: Settings: Miscellaneous: Thermal Sensors: Hardware?

It should be set to "amdtemp".

There are three selections for sensors, one of those is AMD.  Did not work, and neither do the other two, Intel and I think it is something like APIC.  Also tried a series of CLI commands and nothing literally is reported.

There is a widget you can add in the lobby, and htop from mimugmail repo where you can add CPU speed and temps in settings

[phantomsfbw]

newsense, I installed mimugmail's repo yesterday looking for HTOP and did not see it.  Is it by chance under another feature?

[newsense]

Install it in the cli

Code: [Select]

pkg install htop

[phantomsfbw]

So temp will not show under HTOP.  HTOP shows 0.0.% 3000MHz N/A. N/A is where the temp should show.  The 0.0% should show CPU utilization, and the 3000MHz is the incorrectly reported CPU frequency. Tested  using the AMD Ryzen 9 7900x.

Functionally, OPNsense seems to work otherwise, but I wonder if the underpinning BSD operating system is not properly utilizing or optimized for this CPU and AMD 5 Chipset.

For Ryzen 7900x you might want to open a bug on Github, although I imagine it is a matter of time until the patches will show up in FreeBSD
