Hi,
We're now at the finish line of passing WebGL 1.0.1 test on real drivers.
We landed a work-around for the glLinkProgram issue, as it was happening on
many drivers across many OSes.
Now the very last conformance failure on the Intel driver / Mesa 8.0.2 is the
one in this test page,

Hi,
Just so you know: the WebGL 1.0.1 tests are now passing on 2 drivers on Linux:
the Intel Mesa driver, and the NVIDIA driver.
Technically that's enough for us to claim conformance (we need to pass with 2
drivers on each OS we support).
But I'd really like to include the Radeon driver in the
Note: as usual, testing should use either Firefox Nightly (nightly.mozilla.org,
currently version 17.0a1) or Chromium / Chrome Canary.

Hi List,
This is just some good news. Recently, I wrote to this list [1]

versions, and consequently many recent system, including Mesa >= 7.10,
were whitelisted. At that time, unfortunately, we were blacklisting Gallium.

Hi List,
At Mozilla we've been wondering if we could get a good software fallback for
users who can't get hardware-accelerated WebGL. Mesa llvmpipe seems like the
best open source OpenGL renderer, right? At least, it performed superbly in our
quick tests.

Not a concern for us: WebGL doesn't expose, or rely on, the fixed function API.
It stays close to OpenGL ES 2.

Hi,
In the WebGL WG, we need to have WebGL 1.0.1 conformance tests fully passing on
multiple, real drivers, before we can claim that WebGL has conformant
implementations.
So we are trying to get people to run these conformance tests on development
versions of their favorite browsers, using rec

I was told to send this to freedesktop.org admins, but as I fully expect

that I would write to this list first and check that there is enough

Hi List,
I realize that you may well not have time to care about WebGL [1] or
Firefox. In that case, I'm still writing because there's a new test
suite, namely the WebGL conformance test suite, that may be of interest
to help find and fix bugs in OpenGL implementations.

Hi,
I'm trying to see how to implement selective whitelisting/blacklisting of
driver versions on X11 (my use case is to whitelist drivers for Firefox). The
naive approach consists in creating an OpenGL context and calling
glGetString(), however that is not optimal for me, for these reasons:

The problem with this approach is that this is affect the startup time of my

This could conceivably be run in parallel, though. If that eliminated the
performance issue, it would remain that such a solution is a lot m
