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

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