Subject: mesa-swx11-source: indirect rendering broken on 64-bit platforms

Date: Fri, 21 Apr 2006 20:17:13 -0400

[Message part 1 (text/plain, inline)]

Package: mesa-swx11-source
Version: 6.4.1-0.4+ucko1
Severity: important
Tags: patch upstream

[XSF: when this patch is in, please bump xorg-server's build dependency
on mesa-swx11-source accordingly in order to pick up the fixes.]

As reported at https://bugs.freedesktop.org/show_bug.cgi?id=5835 and
https://bugs.freedesktop.org/show_bug.cgi?id=6419, the X server's
indirect rendering code (built from mesa-swx11-source) falls over on
64-bit systems, with the server reporting errors of the form

No matching visual for __GLcontextMode with visual class = N (N), nplanes = N

and libGL reporting corresponding errors of the form

3D driver claims to not support visual 0xN

The underlying problem seems to be data type mismatches (some due to
Mesa defaulting to the wrong thing in the absence of dix-config); I
was able to correct it with the small attached patch, merged from
three single-file Gentoo patches.  Could you please apply it, or one
of those cited in fd.o bug #5835 (which I didn't run across until
later)?

Thanks!

Marcelo recently uploaded a fixed version of Mesa (thanks!); as such,
please go ahead and version xorg-server's build dependency on
mesa-swx11-source to

    mesa-swx11-source (>= 6.4.2-1), mesa-swx11-source (<< 6.5)

Thanks!

As a version of xorg-server with an even stricter Mesa requirement
(per #383334) has just hit unstable (woohoo!), this bug no longer
applies; it had been mostly a theoretical concern for the previous
while anyway.
