Beispiel #1

static void cg3_loadcmap (struct fb_info_sbusfb *fb, struct display *p, int index, int count)
{
	struct bt_regs *bt = &fb->s.cg3.regs->cmap;
	u32 *i;
	int steps;
	        
	i = (((u32 *)fb->color_map) + D4M3(index));
	steps = D4M3(index+count-1) - D4M3(index)+3;
	                        
	*(volatile u8 *)&bt->addr = (u8)D4M4(index);
	while (steps--)
		bt->color_map = *i++;
