.Dd February 23, 2010 .Dt CORETEMP 4 x86 .Os .Sh NAME .Nm coretemp .Nd Intel Core on-die digital thermal sensor .Sh SYNOPSIS .Cd "coretemp* at cpu?" .Sh DESCRIPTION The .Nm driver provides support for the on-die digital thermal sensor present on Intel Core and newer CPUs.
p The temperatures can be observed by using the .Xr envsys 4 .Tn API or the .Xr envstat 8 command. Temperatures are reported for each core separately. .Sh EVENTS The .Nm driver is able to send a .Em critical event to the .Xr powerd 8 daemon. The script
a /etc/powerd/scripts/sensor_temperature will be executed by the daemon (if running) when the limit has been reached. .Sh SEE ALSO .Xr envsys 4 , .Xr envstat 8 , .Xr powerd 8 .Rs .%A Michael Berktold .%A Tian Tian (Intel Corporation) .%T CPU Monitoring With DTS/PECI, White Paper .%D September 2010 .%U http://edc.intel.com/Download.aspx?id=2612 .Re .Sh HISTORY The .Nm driver first appeared in .Fx 7.0 . It was later ported to .Nx 5.0 . .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Rui Paulo Aq Mt rpaulo@FreeBSD.org as part of a Google Summer of Code project.
