You're talking about the OpenGL conformance tests. This is a test suite
that tests correctness of some features in OpenGL. You have to sign a
license arrangement with SGI to get access to them as it is part of the
OpenGL branding process. Brian has a copy for his personal use with
Mesa. The tests are not publically available.
It may be possible for XFree86 to sign an agreement with SGI to get
access to them. VA had worked out a zero cost arrangement with SGI.
Realize there are some issues with this. If all you want is more tests
to run with OpenGL they would work. You should realize their coverage of
OpenGL is actually quite limited, so passing them doesn't tell you a
lot. Also, you can only claim a specific set of binaries pass
conformance. That means XFree could test their releases, but this would
be useless to all the vendors, since they always repackage the release.
Building a better test suite that is open would be a real
benefit. That's what Glean is all about. I think there'd be more value
in building out Glean than working with the OpenGL brand conformance
tests. Building good tests can be challenging, but it might be a good
project if someone is interested.
