28 Say Y here, if your user-space applications are capable of
29 notifying the frame buffer driver when a change has occurred in
30 the frame buffer content and thus a reload of the image data to
31 the external frame buffer is required. If unsure, say N.

45 On systems in which video memory is in system memory
46 (SDRAM) this will speed up graphics DMA operations.
47 If you have such a system and want to use rotation
48 answer yes. Answer no if you have a dedicated video
49 memory, or don't use any of the accelerated features.
