Last change on this file since 7da160b was a71c158, checked in by Martin Decky <martin@…>, 16 years ago

kernel output devices now suport multiple instances (except ski and sgcn, which respect the same interface, but behave as singletons)
if more than one output device gets initialized, the output is cloned to all of them
get rid of arch_grab_console() and arch_release_console() (output devices can implement a generic "redraw" method, input devices respect the "silent" global variable)
