That is what input layer for. Userspace is supposed to listen to kEY_WLAN/KEY_BLUETOOTH events and do its things. Alernatively rfkill-input will do smple on/off toggling on switches that userspace did not claim. > > How about polling twice a second?

You are concerned with the load on the EC caused by constant polling but are you OK with apllications readig sysfs attributes constantly (rfkill attributs are exported 0644 or 0444 so anyone could read them)? Do you want the driver to do throttling? Do you want rfkill to implement throttling? Driver specific? All in all it is alot of pain for no reeal gain. -- Dmitry ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
