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     AMD K9 is not supported because temperature reporting has been replaced by Maltese.
