Nouveau With Mesa 7.9 Is Better, But Still Slow

Originally posted by marek View PostNouveau drivers don't use any kind of buffer management that comes with Gallium, which helped us to get a lot of speed. For example pb_bufmgr_* managers are used only in r300g, r600g, and svga. u_upload_mgr is only used in those three plus i965. Maybe they have something in the kernel?

At one point, I was getting really good framerates on freedoom, and there weren't too many artifacts, either. I guess the speed increase was a regression, since it hasn't been that fast since, but the quality is still good.
I posted some screenshots a while back (one a month ago, and another a month before that) on identi.ca, for anyone interested.
...apparently the links expired. Here are the original links: Screenshot 1 Screenshot 2

Right, except I was more interested in how the Mesa devs are planning on handling the situation...
Eric Anholt mentioned on #dri-devel that Intel was fine with just having a configure switch for patented stuff: http://people.freedesktop.org/~cbril...2010-08-31.log
It would be interesting to know if others are okay with that too. I guess most of this is discussed off-list though, so it would be interesting to know how things are progressing.

I say it's gonna take another 3 years until we got reliable and fast OpenGL 2.1 support but even today there's many folks already learning the new 3.x so in like 3 years the "fast and reliable" 2.1 version is gonna be too little too late. Not grumpy, it's true.
No, this is the whole point. With Gallium3D, OpenGL is just another state tracker, and the driver is nothing directly to do with it. When ATI and Nouveau Gallium3D is fast, little and ideally nothing, would need changing for a new OpenGL (or any other graphics API). The new state tracker would get written once and it would work with all the Gallium3D drivers. The graphics API is completely abstracted away from the driver.

Respectively, if these corps were mostly desktop OS and desktop apps providers (forget mobile), they would have poured tons of money into buying/lobbying/bribing to solve (quickly) pretty much any issues and patents that matter.
That's why these issues get solved slowly despite discussions. Individuals play a more important role here but obviously can't solve them anywhere as quickly as (rich) corps do.

It's still rather pathetic that an "open" standard requires you to pay for patents or get sued. That's not open, in any sense.
