Wonderful!

This page has some starting points for new Mesa developers:
https://docs.mesa3d.org/helpwanted.html

You mention a loader, can you explain that to me?

Our 3D APIs are often thin veneers over hardware drivers. When you link
against the Vulcan library, that library figures out which hardware driver
matches your GPU and then loads it and tries to get it if the way as much
as possible.

By the way, I am not used to using a mailing list, if this email is

Following up on list is generally preferred so others can learn from your
questions and the communities answers.

We also suggest you look for the appropriate list based on topic. This one
is shifting to development, do best to start looking at the various Mesa
developer's lists for follow up.

Hope this helps!
