NAMEacpi_toshiba - Toshiba HCI interface
SYNOPSISTo compile this driver into the kernel, place the following line in your kernel configuration file:
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:
DESCRIPTIONHCI is Toshiba's Hardware Control Interface which is somewhat uniform across their models. The ifconfig driver allows the user to manipulate HCI-controlled hardware using a number of sysctl(8) variables.
SYSCTL VARIABLESThe following sysctls are currently implemented:
- Causes active cooling to be forcibly enabled (`1' ) or disabled (`0' ) regardless of the current temperature.
Sets the active display to use according to a bitwise OR of the following:
- No display
Only some systems (i.e., the Libretto L5) support video switching via this hardware-specific driver. Use the acpi_video4 driver for generic video output support.
- Makes the LCD backlight brighter or dimmer (higher values are brighter).
- Turns the LCD backlight on and off.
- 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.conf5, which is parsed at boot-time.
LOADER TUNABLESThe 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.conf5.
