CORETEMP(4) BSD Kernel Interfaces Manual CORETEMP(4)NAME
coretemp -- device driver for Intel Core on-die digital thermal sensor
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device coretemp
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
coretemp_load="YES"
DESCRIPTION
The coretemp driver provides support for the on-die digital thermal sensor present in Intel Core and newer CPUs.
The coretemp driver reports each core's temperature through a sysctl node in the corresponding CPU device's sysctl tree, named
dev.cpu.%d.temperature.
SEE ALSO sysctl(8)HISTORY
The coretemp driver first appeared in FreeBSD 7.0.
AUTHORS
The coretemp driver was written by Rui Paulo <rpaulo@FreeBSD.org> as part of a Google Summer of Code project. This manual page was written
by Dag-Erling Smorgrav <des@FreeBSD.org>.

ACPI_AIBOOST(4) BSD Kernel Interfaces Manual ACPI_AIBOOST(4)NAME
acpi_aiboost -- ASUS AI Booster hardware monitor
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device acpi_aiboost
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
acpi_aiboost_load="YES"
DESCRIPTION
The acpi_aiboost driver provides support for monitoring the hardware sensors in recent ASUS motherboards. The driver uses ACPI as the back-
end to fetch sensor values and descriptions and provides its data via the sysctl(8) interface, under dev.acpi_aiboost.0 namespace. Descrip-
tions for these values are available with sysctl -d.
The acpi_aiboost driver typically has 7 sensors, depending on the motherboard and chipset:
Sensor Units Typical Use
CPU uK CPU Temperature
MB uK MB Temperature
VCC uV DC Core Voltage
+3.3V uV DC +3.3 Voltage
+5V uV DC +5 Voltage
+12V uV DC +12 Voltage
CPU RPM CPU Fan
SEE ALSO acpi(4), sysctl.conf(5)sysctl(8)HISTORY
The acpi_aiboost driver first appeared in FreeBSD 7.0.
AUTHORS
The acpi_aiboost driver was written by Takanori Watanabe. This manual page was written by Juan Romero Pardines, who adapted the code for
NetBSD, and adopted back to FreeBSD by Takanori Watanabe.
BUGS
It's possible to modify voltages via the ACPI methods in the DSDT, but for now the driver only reports the sensors' values. CPU Q-Fan is
another thing that is typically specified in the ACPI namespace, and in the future we should handle this feature (to enable or disable auto-
matic/manual fan mode).

Is it possible to have a bash script pick the highest and lowest values of four variables? I've been googling for this but haven't come up with anything. I have a script that assigns variables ($c0, $c1, $c2, and $c3) based on the coretemps from grep/sed statements of sensors. I'd like to also... (5 Replies)
Hello,
I have a Toshiba Satellite A505-S6965. My hardware is as attached via the Hardinfo report in pdf format.
Here is the most recent kernel error. It never says it is shutting down. It just "dies" even after saying the temp/speed is normal.
