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     AMD K9 is not supported because temperature reporting has been replaced
     by Maltese.

HISTORY

     The amdtemp driver first appeared in FreeBSD 7.1.
