Not getting temperature from AMD FX-6300

G

G_Nerc

Good day!
On my system FreeBSD 9.1 amd64 I can't get information about processor temperature:
  • CPU: AMD FX-6300 (3.5ГГц, 8Mb, Socket AM3+)
  • MB: ASUS M5A97 R2.0 (AM3, AMD970/SB950)
I'm trying
Code: 
device amdtemp
and
Code: 
device coretemp
in kernel config, but there is nothing in output of:
$ sysctl -a| grep -i temp
except
Code: 
device amdtemp
hw.usb.template: 0
dmesg(8) from that PC on PASTEBIN
 
In case you don't know: you can load kernel modules with kldload(8), you don't have to compile a new kernel.
coretemp(4) is for Intel Core cpus, it won't work with AMD cpus.
Since this is a motherboard from Asus, have your tied loading the aibs(4) kernel module? Perhaps it will work.
 
tingo thanks!
Yes I know that possible kldload modules, and I try that, just I know there is possible situation that kldload'ed module may work different (or not work) for example ndis.ko
And I know that coretemp for intel processors, I'm just try all variants :)
I'm try kldload aibs, and it doesn't appears something new in output of sysctl -a | grep -i temp
 
The FreeBSD 9.1 amdtemp kernel module lacks support for Bulldozer and newer cores. Take a look at the modules Makefile, find the source file (sys/dev/amdtemp/amdtemp.c), get it from -CURRENT and build, install and load the new module.
 
Yes Crest that solution working! But it seems some not fully adequate information:
sysctl -a | grep -i temp
Code: 
dev.cpu.o.temperature: 16.2C
But PC located at office without condition so I don't think 16.2C is right temperature for processor core , I'm not in that office now, I will check when I will be at place.
What needs to do for best calibrate output from amdtemp for that processor?

Unfortunately, the latest revision doesn't compile on FreeBSD 8.3-stable:

Stop in /usr/src/sys/modules/amdtemp.
I'll ask for a MFC on the -stable mailinglist.
