NVIDIA Publishes Code For X Synchronization Fences

I don't know why they are not releasing specs, but I still want them.
AMD went through a lot of trouble to produce specs in a releasable state. I haven't even seen goodwill from Nvidia. Only the "you don't really need open source" mantra and an obfuscated driver which was dropped in favour of the VESA one.

(interestingly enough, I used to do that for a job).

Q: AMD was able to open source and/or document a lot by separating out the parts they couldn't legally disclose. Similar problems have been cited as preventing NVIDIA from open sourcing their driver (licensed 3rd parts code, etc) or documentation. Could nVidia use the same strategy?
A similar strategy might be technically possible for NVIDIA, but for better or worse I think it is quite unlikely. There are several reasons for this:
- For competitive reasons on other platforms, I don't think we would ever open source any of our cross-platform driver source code (which is 90%+ of the Linux driver... see my earlier description of code sharing). The Linux-specific pieces of the driver code base don't really stand on their own, and generally need to change in sync with the cross-platform code, so I don't believe it would be practical to just open source the Linux-specific pieces.
- We have developed substantial IP in our graphics driver that we do not want to expose.
- Unfortunately the vast majority of our documentation is created solely for internal distribution. While at some point it may be possible to release some of this information in pubic form it would be quite a monumental effort to go through the vast amounts of internal documents and repurpose them for external consumption.

AMD deserve much praise for the effort they went to opening their specs. It helped me along somewhat in my decision to buy the 5870. Not the only reason mind you, just one of many factors.
It's one clear difference between the two companies.
While I can happily agree that nVidia don't do as well as AMD for the Linux platform as a whole as I've said in the past, I don't believe that it follows that nVidia are bad. They aren't as good, but they're not bad.

Interesting discussion, albeit circular at times. Let me point out something:

(*) This number may be wrong, it doesn't affect the argument.

Yeah tell that to my riva tnt2 ... and I do not fscking care that it's old crap or whatever... It's enough for a office pc ...
Similiar ATI hardware would be still supported by X drivers while ATM the PC with that riva tnt2 has to stay with old distro version ...

But I can run a 2001 era GeForce 2 MX-400 with Ubuntu 10.04 with a couple of clicks. Ubuntu ships binary drivers for them. It compares pretty favourably with fglrx.
