framebuffer: how to use image_blit from userspace ???


I have been searhing kernel source for hours, i cant find how to use hardware accelerated image blit from my userspace application.

fbmem.c handles the basic hardware ioctl operations, like pan_display etc,
then the default switch case is

Code:
default:
		if (fb->fb_ioctl == NULL)
			return -EINVAL;
		return fb->fb_ioctl(inode, file, cmd, arg, info);
The framebuffer driver ( geode-lx ) definatly registers hardware accelerated image_blit / copyarea functions..

but i cannot find how to use them ?

i assume its triggered via some standard ioctl, but i cannt find it anywhere..

any idea's ?
