You could patent it.
It doesn't matter how wonderful the secret technology is.
Without FLOSS drivers I can't use it.
If I can't use it I'm not going to buy your chips.

I happen to agree that a stable and feature complete open driver is desirable, but I don't know who's going to pay for the full-scale development effort you want. Certainly not the Linux gaming crowd.
Frankly, all I see from you is a bunch of rude sanctimony based upon a profoundly ignorant view of the industry and some bad religious dogma.
My view may in fact be "unacceptable", but let's see a business case that might influence the businesses involved to change their thinking.

My belief, coming from someone with at least a minimal knowledge of computer security, is that "the enemy" (eg. nVidia/Intel) has an infinite number of smart techs with an infinite number of electron microscopes and an infinite number of disassemblers figuring out the clever hack that gave you a better generation of cards at a given time. I see compiling the driver as nothing more than simple obfuscation of the code, that doesn't really get in the way of "the enemy" figuring it out, and hurts no one except those that aren't "the enemy".
I know there's complexities like real-world economics of reverse engineering and the advantage a few weeks of development time can give you, and I can imagine the niggling feeling inside the back of an exec's mind that doing this also keeps entry barriers high enough to keep small companies from being a threat, but in the end it harms everyone, and I'll always be pissed off about it.
I have faith that the open-source driver(s) will be good enough for my needs though (graphics acceleration without any DRM nonsense), and I have hope that the proprietary driver will eventually go away, but I understand that the only way that'll happen is if things like DRM go away, and that's a much bigger battle...
Actually, just thinking about the way Digital Rights/Digital Restrictions Management is one of the reasons the proprietary driver exists, what I'd like to see are open-source GPU drivers, developed by the GPU manufacturers, that are so high-performance, prevalent, and well documented/abstracted that it pushes the onus of writing separate "drm drivers" to the content providers themselves

Once the DMCA gets pulled, and it will get pulled, we will see DRM fall flat on it's face... Already most major content industries are rapidly shrinking because of it, and when the DMCA gets pulled then they'll be in a situation that will turn those industries on there heads...
The cool thing though is that when it's all done the content industries will come out of it better then they are today. Modern and efficient with digital distribution that isnt severely limited. I cant wait for the DMCA to get pulled. I think it is the very best thing that can happen, and it will happen.

Even if the GPL said 'you can not use this code to learn anything' it would be unenforcible. Nobody's ideas are sacred from duplication under any sort of law, even patent law. (which is designed for the express purpose of forcing companies to divulge inventions to the general public, not hide them).
You can try to obsufcate the code by releasing it in machine code only form, but there isn't anything that will prevent people from disassembling it or reverse engineering it. Reverse engineering hardware and software is still perfectly legal, and is in fact necessary for a technology driven society.
-----------------
Oh well there isn't any point in telling you this, of course. It's not like it's your decision or likely that anybody would listen to you. You guys are still doing tremendous work and I look forward to my next hardware purchase with that in mind.
----------------
Someday everybody in the hardware world will will realize that refusing to disclose how hardware work to their own paying customers is not a effective way to compete in the market place.

Trust me, I have read all the versions more times than I even want to admit. Every stinkin' version is longer and harder to read than the one beforeLast edited by duby229; 06 September 2008, 10:52 PM.

So what your saying is that ATi wants to prevent better implementations? That sure is what it sounds like... OK, so now motives and allegiances have been revealed. As they say the truth will out.
"So what you're saying is that ATI wants to prevent better implementations BY THE COMPETITORS?"
