another question.

Hi, thanks for you answer how can I understand this? ps3fb driver and Mesa Cell driver are totally different things, there are some documents to explain this?, I want to understand Mesa3D, and your relation with Xorg, and Kernel drivers..

answer:

Sorry but I do not have time to explain everything.

The Mesa Cell driver implements OpenGL for 3D graphics.

The ps3fb driver is a low-level driver for simply displaying the framebuffer.

If you use google, you can probably find more information.

I can't found this information in google, someone can help me? I want to work on linux, and write drivers. thanks so much.

Mesa implements 3D using OpenGL. Some Mesa drivers are accelerated, some aren't. X.Org drivers implement 2D, TV-out, multi-monitor support etc. Both of them use the kernel. edit: To clarify: Mesa and X.org drivers aren't replaceable, they are both used when needed.
