OpenGL in the kernel

OpenGL in the kernel

[Dmitry M Shatrov]

I think this is the right place to ask it for, sorry if not.
I heard a few about future OpenGL implementation in the Linux kernel, 
but failed to find any resource on this question. I also remember a 
message from this list about its author's experiments with Mesa in this 
key..
Does anybody work on the subject now? Could you help me with (if there 
are any) some links or just explain what's this really about?

With best regards, Dmitry M. Shatrov

As a rule: KERNEL IS WRONG PLACE.

There are some primitive things that to an extent make sense, but
WHOLE OpenGL (which alone is nothing) or any other graphics server 
entirely in kernel ?   No way.

The XFree86 server can use kernel supplied DRI (Direct Rendering 
Interface) facilities, if such are available.

You can find more about this recurring topic in list archives.

You are probably thinking of dri which is the kernel side support for
graphic acceleration, not opengl. opengl is a userland thing not kernel.

dri-devel or dri-user is probably a better place. Try dri.sf.net.

It would certainly be productive to have certain system-level things in 
the kernel, such as support for interrupts and DMA, but we already have 
that in the form of DRI, and there is no other reason to put something 
like that into the kernel.  What advantage would there be that would 
outweigh all of the numerous disadvantages?
