A Fresh Look At The AMD Radeon Gallium3D Performance

@whizse
It seems that every gallium driver has got issues showing the reference pictures in test 3 and test 4 does not show anything or renders incorrectly. intel 945 without gallium renders everything correctly, intel snb has bad rendering in test 4. As additional error with nouveau (tested with series 7 and 9): screenshot with n crashes the driver. I would suggest to test every driver against gl2benchmark and trine. trine is also a good test as it does not work correctly with nouveau series 7 and shows nothing with intel snb. Of course heaven would be interesting too. Only testing openarena (and quake live) is boring, that works basically everywhere...

The other issue with opening up the closed source driver is that the coding styles are VERY different and there are abstraction layers in various modules so that we can share the code with other OSes. This won't fly in the kernel. The driver would have to go into staging and it would be a huge amount of work to change it to match the kernel style guidelines. Plus, once the coding style got changed, it would be nearly impossible to share code between OSes since the two code bases would be so different. So that defeats the main purpose of sharing code.

Originally posted by Kano View Postthe oss driver support is very basic when you compare opengl features. xvba nobody really needs without full h264 l5.1 support. if you want to play a game (or at least look at the heaven demo) with tesselation then you are lost without binary driver. it is fun to test oss drivers, with my intel atom netbook with gma 945 even gl2benchmark runs correctly. fbo (test 4) does not work with snb and other oss drivers do not even show the reference pictures correctly. i really would like to see it running with every oss driver.

Well, anyway I would be very interested in seeing some Gallium vs. blobs benchmarks that measure BGE 2.5+. In fact I might be willing to write some test profiles myself eventually (if I find the time).
i personally don't use the game engine
but even then you need to create content first

Blender 2.5+ benchmarks please

this is something you actually use compared to benches like lightsmark

These are very nice results, BTW.
AFAIK, we are still missing 2d tiling, texture tiling and Hyper-Z. With these goodies, we should be more competitive.
