ACPI_TOSHIBA(4)	       BSD/i386 Kernel Interfaces Manual       ACPI_TOSHIBA(4)

     acpi_toshiba — Toshiba HCI interface

     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):


     HCI is Toshiba's Hardware Control Interface which is somewhat uniform
     across their models.  The acpi_toshiba driver allows the user to manipu‐
     late HCI-controlled hardware using a number of sysctl(8) variables.

     The 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

	     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.
	     Makes the LCD backlight brighter or dimmer (higher values are
	     Turns the LCD backlight on and off.
	     Sets the CPU speed to the specified speed.	 This provides func‐
	     tionality 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.

     The tunable enables or disables the func‐
     tion keys on the keyboard.	 Function keys are enabled by default.

     This behaviour can be changed at the loader(8) prompt or in

     acpi(4), acpi_video(4), loader.conf(5), sysctl.conf(5), sysctl(8)

     The acpi_toshiba driver first appeared in FreeBSD 5.1.

     The acpi_toshiba driver was written by Hiroyuki Aizu ⟨⟩.
