add the ability for userland to be notified of changes on gpio pins via a select(2)/read(2) interface. Change the interrupt handler from filtered to threaded. Because of the uiomove() calls in the new interface, change locking from standard mutex to sx. Add / restore the at91_gpio_high_z() function. Reviewed by: imp (long ago) |
