CONFIG_NWBUTTON: NetWinder Button

General informations

The Linux kernel configuration item CONFIG_NWBUTTON:

Help text

If you say Y here and create a character device node /dev/nwbutton with major and minor numbers 10 and 158 ("man mknod"), then every time the orange button is pressed a number of times, the number of times the button was pressed will be written to that device.

This is most useful for applications, as yet unwritten, which perform actions based on how many times the button is pressed in a row.

Do not hold the button down for too long, as the driver does not alter the behaviour of the hardware reset circuitry attached to the button; it will still execute a hard reset if the button is held down for longer than approximately five seconds.

To compile this driver as a module, choose M here: the module will be called nwbutton.

Most people will answer Y to this question and "Reboot Using Button" below to be able to initiate a system shutdown from the button.
