NAME¶
amdtemp — device driver for AMD K8, K10 and K11 on-die digital thermal sensorSYNOPSIS¶
To compile this driver into the kernel, place the following line in your kernel configuration file:device
amdtemp
Alternatively, to load the driver as a module at boot time, place the following
line in loader.conf(5):
amdtemp_load="YES"
DESCRIPTION¶
The amdtemp driver provides support for the on-die digital thermal sensor present in AMD K8, K10 and K11 processors. For the K8 family, the amdtemp driver reports each cores' temperature through a sysctl node in the corresponding CPU devices's sysctl tree, named dev.amdtemp.%d.sensor{0,1}.core{0,1}. The driver also creates dev.cpu.%d.temperature displaying the maximum temperature of the two sensors located in each CPU core. For the K10 and K11 families, the driver creates dev.cpu.%d.temperature with the temperature of each core.BUGS¶
AMD K9 is not supported because temperature reporting has been replaced by Maltese.SEE ALSO¶

The amdtemp driver first appeared in FreeBSD 7.1.AUTHORS¶
