This driver provides support for extra features of ACPI-compatible ASUS laptops.
It may also support some MEDION, JVC or VICTOR laptops (such as MEDION 9675 or
- VICTOR XP7210 for example). It makes all the extra buttons generate standard
- ACPI events that go through /proc/acpi/events and input events (like keyboards).
+ VICTOR XP7210 for example). It makes all the extra buttons generate input

On some models adds support for changing the display brightness and output,
switching the LCD backlight on and off, and most importantly, allows you to
blink those fancy LEDs intended for reporting mail and wireless status.

That's all, now, all the events generated by the hotkeys of your laptop

Hotkeys are also reported as input keys (like keyboards) you can check
which key are supported using "xev" under X11.
------------------
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. Additionally, loading the driver with the
-debug option will report all events in the kernel log.

+Additionally, loading the driver with the debug option will report all events
+in the kernel log.
The "scancodes" passed to the input system (that can be remapped with udev)
are indexes to the table "sony_laptop_input_keycode_map" in the sony-laptop.c
This attribute has poll()/select() support.
- hotkey_report_mode:
- Returns the state of the procfs ACPI event report mode
- filter for hot keys. If it is set to 1 (the default),
- all hot key presses are reported both through the input
- layer and also as ACPI events through procfs (but not
- through netlink). If it is set to 2, hot key presses
- are reported only through the input layer.
-
- This attribute is read-only in kernels 2.6.23 or later,
- and read-write on earlier kernels.
-
- May return -EPERM (write access locked out by module
- parameter) or -EACCES (read-only).

Non hotkey ACPI HKEY event map:

-Events that are not propagated by the driver, except for legacy
-compatibility purposes when hotkey_report_mode is set to 1:
-
-0x5001 Lid closed
-0x5002 Lid opened
-0x5009 Tablet swivel: switched to tablet mode
-0x500A Tablet swivel: switched to normal mode
-0x7000 Radio Switch may have changed state
-
Events that are never propagated by the driver:
0x2304 System is waking up from suspend to undock
0x2305 System is waking up from suspend to eject bay
0x2404 System is waking up from hibernation to undock
0x2405 System is waking up from hibernation to eject bay
+0x5001 Lid closed
+0x5002 Lid opened
+0x5009 Tablet swivel: switched to tablet mode
+0x500A Tablet swivel: switched to normal mode
0x5010 Brightness level changed/control event
0x6000 KEYBOARD: Numlock key pressed
0x6005 KEYBOARD: Fn key pressed (TO BE VERIFIED)
+0x7000 Radio Switch may have changed state
+
Events that are propagated by the driver to userspace:
cycle, or a system shutdown. Obviously, something is very wrong if this
happens.
-Compatibility notes:
-
-ibm-acpi and thinkpad-acpi 0.15 (mainline kernels before 2.6.23) never
-supported the input layer, and sent events over the procfs ACPI event
-interface.
-
-To avoid sending duplicate events over the input layer and the ACPI
-event interface, thinkpad-acpi 0.16 implements a module parameter
-(hotkey_report_mode), and also a sysfs device attribute with the same
-name.
-
-Make no mistake here: userspace is expected to switch to using the input
-layer interface of thinkpad-acpi, together with the ACPI netlink event
-interface in kernels 2.6.23 and later, or with the ACPI procfs event
-interface in kernels 2.6.22 and earlier.
-
-If no hotkey_report_mode module parameter is specified (or it is set to
-zero), the driver defaults to mode 1 (see below), and on kernels 2.6.22
-and earlier, also allows one to change the hotkey_report_mode through
-sysfs. In kernels 2.6.23 and later, where the netlink ACPI event
-interface is available, hotkey_report_mode cannot be changed through
-sysfs (it is read-only).
-
-If the hotkey_report_mode module parameter is set to 1 or 2, it cannot
-be changed later through sysfs (any writes will return -EPERM to signal
-that hotkey_report_mode was locked. On 2.6.23 and later, where
-hotkey_report_mode cannot be changed at all, writes will return -EACCES).
-
-hotkey_report_mode set to 1 makes the driver export through the procfs
-ACPI event interface all hot key presses (which are *also* sent to the
-input layer). This is a legacy compatibility behaviour, and it is also
-the default mode of operation for the driver.
-
-hotkey_report_mode set to 2 makes the driver filter out the hot key
-presses from the procfs ACPI event interface, so these events will only
-be sent through the input layer. Userspace that has been updated to use
-the thinkpad-acpi input layer interface should set hotkey_report_mode to
-2.
-
-Hot key press events are never sent to the ACPI netlink event interface.
-Really up-to-date userspace under kernel 2.6.23 and later is to use the
-netlink interface and the input layer interface, and don't bother at all
-with hotkey_report_mode.
-
Brightness hotkey notes:
Thus this option is a debug option that helps to write ACPI drivers
and can be used to identify ACPI code or EC firmware bugs.
-config ACPI_PROC_EVENT
- bool "Deprecated /proc/acpi/event support"
- depends on PROC_FS
- default y
- help
- A user-space daemon, acpid, typically reads /proc/acpi/event
- and handles all ACPI-generated events.
-
- These events are now delivered to user-space either
- via the input layer or as netlink events.
-
- This build option enables the old code for legacy
- user-space implementation. After some time, this will
- be moved under CONFIG_ACPI_PROCFS, and then deleted.
-
- Say Y here to retain the old behaviour. Say N if your
