At the Linux.Conf.Au conference today, Intel has announced NDA-free programming documentation covering the 965 Express and G35 Express IGPs. Intel's display driver has long been open-source, but up until now, they have not been releasing the programming documentation for these products to the public. This move comes months after AMD announced their new open-source strategy and began releasing register documentation on their R500 and R600 GPUs. These newly released documents by Intel even cover 3D and video programming for their IGPs.

Intel's offering seems far more than ATI/AMD have released yet.
...
I've just had a flick through the Intel docs - they are _VERY_ comprehensive. Bus timing registers, memory setup, 2D & 3D core and lots more besides.

Intel have always been very good with documentation. If other manufacturers were as good about it Intel are, we'd all be much better off.
VIA seem to release code but no docs... weird.
Weirder, the code they have released was pretty much just a dump with no further support or updates. S3 used to be good too, but their newer cards like the DeltaChrome & GammaChrome don't exist as far as Open Source is concerned.

Guys, look at this!
1) Open & free full GPU specs documentation.
2) *Very* high documentation quality, with large overview diagrams, clear memory & structures layouts, message sequences, structured chapters & volumes. Woa, now that's impressive to see an actual top technical documentations at this level of quality.
Even if AMD/ATI started first to publish in the open their GPU specs, Intel deserves credits here for being the first doing it *right*, *fully* and *now*.
Let's hope their concurrents will catch up soon.

Blast! Beat me to it ;-) Come on nV... you're WAY behind!
Intel's offering seems far more than ATI/AMD have released yet. The last AMD docs I read didn't specify 2D/3D/ROP/BLT registers just those for video mode setup, overlays, cursors - none of the acceleration stuff or RAM/PCI setup apparently this is coming. VIA seem to release code but no docs... weird.
