# $NetBSD: files.wsfb,v 1.9 2015/05/01 02:00:41 nat Exp $
add genfb, a generic framebuffer console driver that's configured via device properties - all it needs is width and height in pixels, stride in bytes, depth in bits and the framebuffer address. Features: - unaccelerated fb console with colours and virtual consoles - split into console handling and bus frontend - so far there is only a PCI bus frontend which allows to mmap BARs belonging to the graphics controller, others should be easy to add. TODO: - find an opaque way to change the palette ( probably pass a function pointer as property ) since this would need to call some firmware interface which is pretty much always MD - find a clean way to mmap the framebuffer, just returning the physical address works on macppc but not on other architectures. Problem is, that we cannot rely on the address being a bus address - on macppc it is, but for instance on sparc64 it's not.

Provide a stub genfb_cnattach for md code to call to give a hint to the bus driver's match function to return a higher confidence (so it can beat out vga(4), for example). genfb needs-flag so md code can determine if the genfb driver is present.
