Panning is implemented in the framebuffer driver itself, not DirectFB, ie: drivers/video/s3c2410fb.c of the linux kernel tree. > > In the driver, the video framebuffer memory is allocated which has the same > size as the frame buffer size. > I can imagine if the driver would allocate memory for big virtual > framebuffer e.g. 4 times or 2 times the size of the actual framebuffer and > directFB could make used of panning feature.

Thanks. > The implementation of fb_pan_display() is simple. Look at how the the other framebuffer drivers do it. Just ask if you have questions. And because this is under fbdev-devel, you can post questions to the fbdev-devel mailing list.
