AMDTEMP(4) BSD Kernel Interfaces Manual AMDTEMP(4) NAME
amdtemp -- device driver for AMD K8, K10 and K11 on-die digital thermal sensor SYNOPSIS
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AMD K9 is not supported because temperature reporting has been replaced by Maltese.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
