Without diving into this, just sharing my view on auxdisplay subsystem: I consider it _mostly_ (like lim->100% mathematically speaking) as for 7-segment and alike displays, not any comples RGB or so devices. If those devices are capable of representing characters/digits in similar way, we may export linedisp library for them to utilise. -- With Best Regards, Andy Shevchenko
