Indeed this has sat orphaned for too long already. I close it as wontfix
now, since it is really not worth (potentially) breaking existing
installations to introduce new code.

Phil,
thank you for more info. I didn't know that Wishlist in Launchpad
means to be in a complete state.
I think it's confusing. Maybe You should consider to change the status
name to more intuitive (CLOSED, NO FEEDBACK NEEDED?). or provide
easy accessible descriptions of current status names?
VangelistX,
Yeah, the Wishlist bit could be confused, but this bug was reported,
test cased, patch supplied, explained, confirmed as valid and fixed by
the patch. It went Wishlist as being that it is for Hardy, it is a
borderline case for inclusion being that it is not a security fix and
dubious
It seems that newly released Mesa 7.5 will solve the problem with i915
and many other chipsets.

VangelistX,
Any version = 7.0.4 (mesa 7_0 tree) fixes this issue. All versions of
Ubuntu after Hardy are not affected. Please refrain from adding
incorrect static to bug reports when they are in a complete state and
pending actioning i.e. Wishlist (though that means nothing will be
done).
Just for the record:
sudo apt-get install libglut3-dev
gcc fptex_915.c -lglut
So if this lands in hardy-proposed, I'd like to keep it there for at
least two weeks, otherwise I'm ok with it. It slightly bends the rules,
but I see the benefit of enabling more software to run on 8.04 LTS on
For information I have this patch packaged up as
'7.0.3~rc2-1ubuntu3.1~8.04'. For proposed and forward could this be
copied or bumped to '7.0.3~rc2-1ubuntu3.2' so I can stay the
same/upgrade to the official build. Many thanks.
I agree this should spend as long as needed in proposed until it is

For a simple applicable test case. See the test case on duplicate

Thanks for the update. SRU wise I'm ok with the patch if we get a test

After a look with a fellow Crystal Space core dev, we find that
i915_emit_texld() is local to the driver with the following amount of
instances in the Mesa-7.0.3-rc2.orig i915 driver.

Thinking of as many ways as possible to justify inclusion... here goes
another.
Ubuntu wanting to be at the forefront of the netbook arena would of want
to offer as much functionality as possible on them. At present the vast
majority of these devices are Intel GMA 950 graphics based and thus use

Fixed in intrepid.
X maintainers, do you think this is an appropriate SRU? Especially when
looking at the ABI change of i915_emit_texld()? (or is that only
internal?)

Philip, how can this be tested? I. e. what currently doesn't work under
8.04 which would work with this patch?

Without additional analysis into the ABI impact of the i915_emit_texld()
change, I'm not comfortable with this patch as an SRU as currently
written.
If the patch could be refactored to not change i915_emit_texld()'s
parameters, that would alleviate the concerns.
Also, for those of us non-opengl

Under Intel hardware Crystal Space shader apps cannot be run and I
suspect (though have not tested) this may affect other game engines.
This issue will also prevent the totally OSS game

hardware.

There are other examples of swizzling of coords i.e. other vector
operations, but I will keep it down so no bug bloating.

Please consider for update in hardy.
Justification:
Performing of such simple GL operations is a benefit for the LTS and
does not then bar it from day to day users with Intel hardware who wish
to run basic games and others applications.
