Here's a reason for you to ponder.Think about the time its taken for previous generations to get supported by open source -- this is the fastest one yet by FAR.
How many YEARS did it take for R300? And then again for R600 (but not AS long)? This one was LESS THAN ONE YEAR!!!
The R300 original support was obtained mostly without their help- reverse engineered.
The R600 was delayed because of the learning curve actually involved with driving a modern GPU properly, coupled with trying to get the right infrastructure in the framework in place to do it "right" to begin with- something that we'd not seen with the earlier efforts on GPUs, mainly because we'd dealt more with OpenGL v 1.3 capable hardware instead of 1.5/2.X capable stuff.
Yes... Finally. It's not being ugly to say that. It is actually probably more a remark of enthusiasm. We now can finally have something remotely performing in hand for things like Games (and will get more there as they remove the bottlenecks in the framework...) and not have to rely on sub-par Intel hardware to have a FOSS only system configuration to do that with.And now they're already starting to look at the next gen that isn't even out yet? They are almost on top of it! At this rate, the HD7000 series will be supported same day or even before that.
