CONFIG_ACPI_TOSHIBA: Toshiba Laptop Extras

General informations

The Linux kernel configuration item CONFIG_ACPI_TOSHIBA has multiple definitions:

Toshiba Laptop Extras found in drivers/acpi/Kconfig

The configuration item CONFIG_ACPI_TOSHIBA:

Help text

This driver adds support for access to certain system settings on "legacy free" Toshiba laptops. These laptops can be recognized by their lack of a BIOS setup menu and APM support.

On these machines, all system configuration is handled through the ACPI. This driver is required for access to controls not covered by the general ACPI drivers, such as LCD brightness, video output, etc.

This driver differs from the non-ACPI Toshiba laptop driver (located under "Processor type and features") in several aspects. Configuration is accessed by reading and writing text files in the /proc tree instead of by program interface to /dev. Furthermore, no power management functions are exposed, as those are handled by the general ACPI drivers.

More information about this driver is available at http://memebeam.org/toys/ToshibaAcpiDriver.

If you have a legacy free Toshiba laptop (such as the Libretto L1 series), say Y.
