NAME
amdtemp -- device driver for AMD processor 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 Family 0Fh, 10h, 11h, 12h, 14h, and 15h processors. For Family 0Fh processors, the amdtemp driver reports each core's temperature through sysctl nodes, named dev.amdtemp.%d.core{0,1}.sensor{0,1}. The driver also creates dev.cpu.%d.temperature in the corresponding CPU device's sysctl tree, display- ing the maximum temperature of the two sensors located in each CPU core. For Family 10h, 11h, 12h, 14h, and 15h processors, the driver reports each package's temperature through a sysctl node, named dev.amdtemp.%d.core0.sensor0. The driver also creates dev.cpu.%d.temperature in the corresponding CPU device's sysctl tree, displaying the temperature of the shared sensor located in each CPU package. SYSCTL VARIABLES
The following variable is available as both sysctl(8) variable and loader(8) tunable: dev.amdtemp.%d.sensor_offset Add the given offset to the temperature of the sensor. Default is 0. SEE ALSO
loader(8), sysctl(8) HISTORY
The amdtemp driver first appeared in FreeBSD 7.1. AUTHORS

For Family 10h and later processors, ``(the reported temperature) is a non-physical temperature measured on an arbitrary scale and it does not represent an actual physical temperature like die or case temperature. Instead, it specifies the processor temperature relative to the point at which the system must supply the maximum cooling for the processor's specified maximum case temperature and maximum thermal power dissipation'' according to BIOS and Kernel Developer's Guide (BKDG) for AMD Processors, http://developer.amd.com/documentation/guides/Pages/default.aspx.

NAME
acpi_toshiba -- Toshiba HCI interface SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file: device acpi_toshiba Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): acpi_toshiba_load="YES" DESCRIPTION
HCI is Toshiba's Hardware Control Interface which is somewhat uniform across their models. The acpi_toshiba driver allows the user to manip- ulate HCI-controlled hardware using a number of sysctl(8) variables. SYSCTL VARIABLES
The following sysctls are currently implemented: hw.acpi.toshiba.force_fan Causes active cooling to be forcibly enabled ('1') or disabled ('0') regardless of the current temperature. hw.acpi.toshiba.video_output Sets the active display to use according to a bitwise OR of the following: 0 No display 1 LCD 2 CRT 4 TV-Out Only some systems (i.e., the Libretto L5) support video switching via this hardware-specific driver. Use the acpi_video(4) driver for generic video output support. hw.acpi.toshiba.lcd_brightness Makes the LCD backlight brighter or dimmer (higher values are brighter). hw.acpi.toshiba.lcd_backlight Turns the LCD backlight on and off. hw.acpi.toshiba.cpu_speed Sets the CPU speed to the specified speed. This provides functionality similar to the hw.acpi.cpu.throttle_state variable. Higher sysctl values mean lower CPU speeds. Defaults for these variables can be set in sysctl.conf(5), which is parsed at boot-time. LOADER TUNABLES
The hw.acpi.toshiba.enable_fn_keys tunable enables or disables the function keys on the keyboard. Function keys are enabled by default. This behaviour can be changed at the loader(8) prompt or in loader.conf(5). SEE ALSO
