[Mesa-dev] Moving i965 driver to genxml commands and structures

[Jason Ekstrand]

Lois-Francis,

Thanks for taking a crack at this!  There are a couple other people (I put 
them in the Cc) who have talked about doing this so thank you for sending 
the announcement!

My primary request as you dive into this would be that you do things in 
such a way that we can have a fairly tight feedback loop.  I think both Ken 
and myself have a pretty clear idea of what things should look like when 
you're done and I'd like to avoid any chance that you send a 50 patch 
series and then get told to go back through the whole thing and make some 
mechanical change.

One other comment: look at blorp.  It's already using genxml with the i965 
driver although there's a but of an abstraction layer there.  It should 
give you a decent idea about how to make a brw_emit() macro by combining 
things and removing the abstraction.
