AMDTEMP(4) 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 core's 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 sen- sors located in each CPU core. For the K10 and K11 families, the driver creates dev.cpu.%d.temperature with the temperature of each core. SEE ALSO sysctl(8) HISTORY The amdtemp driver first appeared in FreeBSD 7.1. AUTHORS Rui Paulo <rpaulo@FreeBSD.org> Norikatsu Shigemura <nork@FreeBSD.org> BUGS AMD K9 is not supported because temperature reporting has been replaced by Maltese. FreeBSD 9.1 April 8, 2008 AMDTEMP(4)
