The Athlon 200GE you linked to is a Zen microarchitecture CPU:
https://en.wikipedia.org/wiki/Zen_(microarchitecture)#Desktop_APUs

And checking what family that is:
https://en.wikipedia.org/wiki/List_of_AMD_CPU_microarchitectures

We can see it's 17h. Which should be supported by the driver already in FreeBSD 11.2 but somehow isn't.
It might be an edge case. There's not much we can do there.

oh ok... thats too bad.. and thats cool too... and when you say it might be an edge case what does that mean... did i pick a wrong cpu then? i picked it because its low power 35watts and cheapest asus board since doesnt need much ... maybe in 2.4.5 pfsense there be a fix...
thanks for helping so far and finding that info (:

maybe i should bought more expensive motherboard by asus guess its a guessing game lol

It looks to be a regular PCI device. The driver supports these:

https://github.com/freebsd/freebsd/blob/master/sys/dev/amdtemp/amdtemp.c#L79

So if you run pciconf -lv you may be able to see it. If it's not in that lists though it will not be supported.

ACPI should still work however.

In reality I'd be amazed if that CPU overheated so I wouldn't worry too much.

ya thats what i thought too i just figured cuz of the fan but once every 6 months blow off the cpu fan should be good.. i was hoping i could get a 15w version then no need a cpu cooler but you cant get those those be soldered on grr..
but ya i ran that command doesnt look like its in there.. unless its labled under different name

stephenw10

Mmm, nothing obvious there. Maybe it's disabled in the BIOS.

Ah, looks like you might need an extra driver for 17h CPUs. Try this:
kldload amdsmn

It should report a new bus. If you have amdtemp loaded alreadt it might also report the new device.

Steve

nothing worked or least it just says its installed i guess

stephenw10

Ah, Ok. Already loaded on an compatible device I guess.

Steve

ill look in the bios settings but if not no biggy
was hoping pfsense would also tell the cpu fan speed and chassis but i probably asking for too much in that department

This got temps working for my 200GE. Thank you!

Is there anything I should do to make this permanent?

Create the file /boot/loader.conf.local (if it doesn't exist) then add to it the line:

amdsmn_load="YES"
