.Dd April 8, 2008 .Dt AMDTEMP 4 .Os .Sh NAME .Nm amdtemp .Nd device driver for AMD K8, K10 and K11 on-die digital thermal sensor .Sh SYNOPSIS To compile this driver into the kernel, place the following line in your kernel configuration file: d -ragged -offset indent .Cd "device amdtemp" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent amdtemp_load="YES" .Ed .Sh DESCRIPTION The .Nm driver provides support for the on-die digital thermal sensor present in AMD K8, K10 and K11 processors.
p For the K8 family, the .Nm driver reports each core's temperature through a sysctl node in the corresponding CPU devices's sysctl tree, named .Va dev.amdtemp.%d.sensor{0,1}.core{0,1} . The driver also creates .Va dev.cpu.%d.temperature displaying the maximum temperature of the two sensors located in each CPU core.
p For the K10 and K11 families, the driver creates .Va dev.cpu.%d.temperature with the temperature of each core. .Sh SEE ALSO .Xr sysctl 8 .Sh HISTORY The .Nm driver first appeared in .Fx 7.1 . .Sh AUTHORS .An Rui Paulo Aq rpaulo@FreeBSD.org .An Norikatsu Shigemura Aq nork@FreeBSD.org .Sh BUGS AMD K9 is not supported because temperature reporting has been replaced by Maltese.
