Phil is right, the pipeline is still being used
and is the fastest way to render on the framebuffers
where it is used.
As for the MITSHM ifdefs, I believe they are there
for some licensees who might want to build the
jdk w/o the MITSHM support. Although I would
not hazard to guess if it even builds w/o MITSHM
now, I haven't tried in a while.
Thanks,
Dmitri

Hi Clemens,

and DGA, but I wonder wether there are still systems without MITSHM,
and the other way round for DGA.
I believe it may no longer be in use, but Dmitri would have to answer
to be sure. It was a Sun-specific API for coordinating talking
directly to the framebuffer with the X11 server. Since then more work
on the X11 and OpenGL pipelines and the use of MITSHM and the fact
that Sun stopped shipping framebuffers with DGA drivers at some point
made the importance of that pipeline wane...
Well, still its in daily use on my Solaris 10 SPARC SB2000 with FFB2+.
So I'm not sure I'd want to ditch DGA quite yet. I think it should stay
at least for JDK7.
