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 ?
