This mini-driver drives the SNC device present in the ACPI BIOS of
the Sony Vaio laptops.
This mini-driver drives the SNC and SPIC device present in the ACPI BIOS of the
Sony Vaio laptops. This driver mixes both devices functions under the same
(hopefully consistent) interface. This also means that the sonypi driver is
obsoleted by sony-laptop now.
It gives access to some extra laptop functionalities. In its current
form, this driver let the user set or query the screen brightness
through the backlight subsystem and remove/apply power to some devices.
Fn keys (hotkeys):
------------------
Some models report hotkeys through the SNC or SPIC devices, such events are
reported both through the ACPI subsystem as acpi events and through the INPUT
subsystem. See the logs of acpid or /proc/acpi/event and
/proc/bus/input/devices to find out what those events are and which input
devices are created by the driver.
