IA64 is still using the drm-4.0 code, as are the (possibly obsolete)
-ac kernels.  The drm 4.0 makefiles are a pain in the neck and I want
to get rid of them asap.  The SiS direct render is only for drm 4.1 so
now is a good time to question if 4.0 is still required.

How long do people plan to keep drm 4.0 code in their versions of the
kernel?

For 2.5, there probably is no intention of keeping that around.  But can
we honestly ditch it in the middle of a stable kernel?  Personally I
don't use it, but its not polite ...

Linus ditched drm 4.0 months ago.  It only survives in arch add on
patches like ia64 and in -ac trees.

You mean for 2.5?  I don't think there is a good reason to keep
drm-4.0 there.  For 2.4, we should keep it because there might be
folks out there that rely on it.

I know.  I meant we should continue to support the drm-4.0 package. 
It's the usual song ... we shouldn't change interfaces or required tools
in a stable series, and the least we can do is make 4.0 available
somehow, because someone may rely on it.

On the flip side, I don't care, and I suspect the people who actually
are using DRM are on 4.1 now.  Further, if _you_ are maintaining the
cruft and it bothers _you_, then stop :)

No, it also survives as an add-on tarball for the standard kernel:
http://www.kernel.org/pub/linux/kernel/v2.4/drm-4.0.x.tar.bz2

Let me dig through my old mail so I can quote Linus on this... Here's
what he said in his Linux 2.4.8 announcement message (Subject
"Linux-2.4.8", sent on August 10th of this year):

The impression I get (for 2.4) is that DRM 4.1 comes standard but you
should still be able to use 4.0 if you want, via that tarball.

Good.  I will drop drm 4.0 support from kbuild 2.5.

Well, I am on Debian stable, and the only Xfree4 contributed packages
are for 4.0.

I will move on to 4.1 when Debian moves on, but as you know they are
slower than a tired snail when it comes to new releases.

I wonder how many other people use these 4.0 packages off:

deb ftp://debian.cri74.org/debian-cri potato/contrib_luis_sismeiro main
non-free

I said it shouldn't have been ditched, Linus overruled.

That argument doesnt fly. The 4.0 DRM is the only working GMX renderer..

So what DRM can build out of tree easily - e.g. the Caldera LTP
(3.1 early access) had a DRM package built completly out of tree.

David, would you remove drm-4.0 from the ia64 patch if I'd do the work
again and package an up-to-date and ia64-capable drm 4.0 out-of-tree?

Of course it doesn't work. We've performed a software upgrade.

XFree86 4.0, 4.1, ... ship with the DRM kernel modules buildable from
the XFree86 tree too

Been there, done that.

Having seen the XFree build process this doesn't look like an option to
me anymore.  Also a separate tarball easyfies building a new set of modules
for a new kernel a lot.
