Michal, This looks good. Can you summarize what work needs to be done on the drivers as a result of this change?
I'm guessing that drivers that only support a single constant buffer don't need to make any changes, but can you confirm that? Also, is there a cap bit for this, if so what? I know we're looking at alternatives to cap bits, but until they're in place I think we need to keep with the old methods.

An example shader would look like this: FRAG DCL IN[0], COLOR, LINEAR DCL OUT[0], COLOR DCL CONST[1][1..2] MAD OUT[0], IN[0], CONST[1][2], CONST[1][1] END For this to work, one needs to bind a buffer to slot nr 1 containing at least 3 vectors. ------------------------------------------------------------------------------ Throughout its 18-year history, RSA Conference consistently attracts the world's best and brightest in the field, creating opportunities for Conference attendees to learn about information security's most important issues through interactions with peers, luminaries and emerging and established companies. http://p.sf.net/sfu/rsaconf-dev2dev _______________________________________________ Mesa3d-dev mailing list Mesa3d-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mesa3d-dev
