Accelerated framebuffer driver

While searching the net for something completely different a few days ago, I stumbled over this article:

At first glance, it seems to talk about similar issues, so maybe it is helpful to you..

To take advantage of the the NSC accelerated framebuffer, you've got to call the accelerated ioctls() that the NSC driver supports. They do provide some headers (or they do in the version that I've got) in the galproto.h and some interface source in galfns.c.

This would have to be done in Xfree86 if you're using that, and you'd have to modify the Xserver to take advantage of that. Somewhere on my list of things to do if I ever get time is to modify the stock Xfbdev server to support some of the basic acceleration functions.

If you're using the framebuffer directly, then you can do whatever you want, of course.

IMHO, the correct way is to use a standard api like DirectFB
