keymap function for quickstart driver
PATCH 1/1 keymap function for quickstart driver
Hi,
back again with a patch for the quickstart driver that implements a keymap for the runtime events that quickstart generates. A custom keymap can be assigned via a simple udev rule.
Background for this: Fujitsu is going to ship very small systems with no direct eject button for the optical drive. Instead you have a hotkey that is recognized by the quickstart driver. This patch now allows to map the key event (0x1) to the keycode "ejectcd" and then react to this in your desktop manager software.
