The
vidcvideo driver provides support for the video system of the ARM VIDC20 and of the video and sound macrocell of the ARM7500 and ARM7500FE within the
wscons(4) framework. It provides support for both a text-based console display and a memory-mapped frame buffer usable by the X Window System.
The
vidcvideo driver chooses a screen mode to use when
NetBSD starts up, and has no means of changing it thereafter. The driver attempts to choose a screen mode from its built-in list that most closely matches the mode being used under RISC OS. If the built-in list of modes is inadequate, a different one can be substituted by compiling a kernel using the
MONITOR option to refer to a RISC OS ModeInfo file, specifying the list of modes to extract from it in
MODES.
