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 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.

HISTORY

       The amdtemp driver first appeared in FreeBSD 7.1.

BUGS

       AMD K9 is not supported because temperature reporting has been replaced by Maltese.
