Phoronix: Gallium3D Support For Stream Out Arrives

On the same-day as publishing new Gallium3D benchmarks of the ATI R300g driver, we have more Gallium3D news to share. Zack Rusin has just announced a new Gallium3D branch that provides support for "Stream Out" with this advanced graphics driver architecture...

Good to know Zack Rusin has a sense of humor. Hope this is supported on G96 (GeForce 9400M) soon

P.S. - First!

And the benefit is...?

So is it going to make Gallium drivers faster?

Fan of zack

I'm always happy to see Zack Rusin's posts when they appear in the feed from PlanetKDE. You are almost sure to read some funny post about some interesting new development.

No, it's just a mandatory feature in OpenGL 3.0.

No, it's just a mandatory feature in OpenGL 3.0.

Cool, how far are you guys from OpenGL 3.0?

[Remco]

Presumably 0.1 version. (Mesa will jump to 8.0 when OpenGL 3.0 is supported.)

Hence the R600+ hardware requirement...

Thanks, I see. This explains why R600+ hardware supports the feature. However, I also noticed from the mailing list that some R300+ hardware can also support it in a limited fashion. Is that going to be too limited to be useful, since these chips are only capable of OpenGL 2.x?

if hardware supports something - it will be hardware accelerated in mesa.

so, if you would have a card that would support e.g 50% of opengl3 features, you obviously would not have a opengl3 compliant hardware.

but you will get hardware acceleration for those operations that hardware can do.

And if someone has the time to implement it.
