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 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.
HISTORYThe driver first appeared in Fx 5.1 .
