Originally posted by hal2k1 View PostGallium drivers are a work in progress. The comparisons that you linked to do not include any of the performance improvements that are the subject of this thread, nor do they include Page Flipping which will not be available until Linux kernel 2.6.38 is released.

It's just that the number of OSS driver developers is so low, that the devs have opted for a design which improves maintainability and code reuse over hardware-specific tuning.
I can live with that. I can't live with the "kill all OSS drivers" psycho gamerz crowd.

What good then are Phoronix tests?

Pageflipping as it is currently implemented in dri2 only flips during the vblank period (swap interval of 1) so it's limited to the refresh rate. Ideally, we also support pageflipping when the swap interval was 0 as well so you'd get atomic pageflipping (with tearing) for maximum frame rates. dri2 needs to work to enable this however. Even with vblank synchronized pageflipping, it still helps performance in that is reduces memory bandwidth requirements and pipeline latency since you don't have to do an additional blit to copy the back buffer to the front buffer.

I know redhat is very hardcore about security and I'm sure working with some of these companies gives you a whole lot of conciousness that you are working with pedo bear and want to start screaming stranger danger for some odd reason. All you have to do is watch things like the fence sync. They always operate the same way. Create a crisis and then solve it quickly not giving everyone enough time to figure out everything that is going on and why it's going on. They are addicted to creating crisis because they already know how they want it solved and they want it solved with everybody throwing thier hands up in disgust.
