[Mesa-dev] RFC: per-driver extension lists

[Ilia Mirkin]

Hello,

As the outcome of a discussion yesterday on #dri-devel
(http://people.freedesktop.org/~cbrill/dri-log/index.php?channel=dri-devel&date=2014-03-25
starting around 16:30), I've created a small page that lists all
extensions/limits supported by core/compat profiles, per driver:

http://people.freedesktop.org/~imirkin/glxinfo/glxinfo.html

The more astute members of the crowd might notice a distinct
similarity to the apple version[1], but I never claimed to be a
designer :) The nice thing about this implementation is that you just
run a program (listed at the top of that page) to parse glxinfo -l -s
output, and stick it as a js source on the page (and the generated
file calls a 'register' function to register its configs).

There are a few shortcomings -- I'm not completely happy with the
headers (might have to switch to the apple way), there's no history
support, and it's very lacking in driver and version info (I just ran
it on the hw/sw I had easily available). However I'm confident I can
resolve all these, and I don't think they really impact the prototype
evaluation.

Do people think this sort of resource is useful? Counter-productive?
Are you happy with the raw information presented (even if you may be
unhappy about the specific way in which it is presented)? Any other
feedback?

If it's useful, I'll reach out to the various driver teams to get them
to provide relevant glxinfo's and fill it out some more. Perhaps even
look into a version that can receive glxinfo uploads. But I don't
really want to put in more effort if people don't find it useful/it
won't get used.

Let me know what you think (and feel free to send me the output of
parse-glxinfo.py for your setup).

Cheers,

  -ilia
