I've been thinking about this a while ago, but it somehow got itself stuck on
my 'maybe later' stack. My idea was to have devd do the magic here. Agree on
some constants (ACPI_VOLUME_UP, ACPI_VOLUME_MUTE, ACPI_HOTKEY_1,...) that the
specific drivers could send to devd using acpi_UserNotify().
We could then have a devd script (much like we also have power_profile, or we
could rename that to 'acpi_event' or something similar) to catch these events.
notify 10 {
match "system" "ACPI";
match "subsystem" "HOTKEY";
action "/etc/rc.d/acpi_event $notify";
};
To avoid having a notify section for every different device specific acpi
driver, we could either have them all be ACPI_MODULE_NAME("HOTKEY"), or we
could register them under an umbrella hotkey driver. The latter approach
might be nicer. Then we could also add other non-acpi hotkey gadgets (ir
remote controls maybe? :-)) under it?
I'd be interested in hacking at this.
