Phoronix: NV_fill_rectangle Coming To Gallium3D/Nouveau

Red Hat developer Lyude Paul is working on OpenGL NV_fill_rectangle support for Gallium3D and the Nouveau driver...

It sounds like glamor might start using this after it's implemented in nouveau as well...

it sounds like it can be supported only on some nvidia models and glamor needs something with wide support

glamor could use a separate code path for that extension... its not like every driver would need it for glamor to work at all.

Sure, but who's interested in maintaining a separate code path just for a small group of nvidia gpu's is the question.

Marek already went to the trouble of figuring out what intel, nvidia, and amd hardware supports in common. Someone just needs to code up a new mesa extension based on that, and then glamor could use that.

Or like AMD support comes elsewhere.

Ok, my OpenGL-fu is beyond rusty, but why is there a Nvidia specific extension to fill a rectangle?

for optimizing drawing user interfaces with opengl.

The question was what's Nvidia specific for filling a rectangle? That's as primitive an operation as it gets.

in opengl primitive operation is filling a triangle
