AMD Releases 3D Programming Documentation

Michael Larabel writes "With the Free Open Source Developers' European Meeting (FOSDEM) starting today, where John Bridgman of AMD will be addressing the X.Org developers, AMD has this morning released their 3D programming documentation. This information covers not only the recent R500 series, but goes back in detail to the R300/400 series. This is another one of AMD's open source documentation offerings, which they had started doing at the X Developer Summit 2007 with releasing 900 pages of basic documentation. Phoronix has a detailed analysis of what is being offered with today's information as well as information on sample code being released soon. This information will allow open source 3D/OpenGL work to get underway with ATI's newer graphics cards."

Way to go AMD

[schwaang]

For ages, the FOSS community has said "just give us the specs for your graphics cards and we'll write the drivers". Well it looks like AMD is taking real steps in that direction, and I for one, say Thanks!

According to TFA, the small group at AMD who has spent time clearing the docs for legal issues are going to speak at FOSDEM, and the maintainer for the open source driver for AMD/ATI graphics (RadeonHD) will be giving an update.

And thanks also to Intel for putting out their 3D graphics specs last month. These are good days for Linux.

Depends on what you mean by better. There's no doubt that the open source drivers will be more stable and have better software compatibility than the proprietary stuff. The 3d performance will really only matter to the Linux gamers (a very small market, that), as the performance should definitely be more than enough for simpler things like compiz, etc.

You should take a look at the existing 3d drivers. The folks reverse-engineering the r300 series did a pretty good job (well enough for it to be the development platform for xgl). And the open-source drivers also guarantee that the card will continue to work just as well with software written long after the demise of the company (eg. with the 3dfx drivers).

Gamers are not the only ones who like 3D acceleration.

Quickly and off the top of my head, here are two big ones:
1. Compiz/Fusion and the like is gaining popularity.
2. Some applications NEED good 3D or they crawl. See Blender for instance.

Of these, I would say gaming would be the least demanding - at least if my assumption that "stable is harder than fast" is correct.

Sure, Blender needs good OpenGL acceleration. But, nobody is going to be that concerned about getting an extra 1 fps in Blender. If proprietary drivers go twice as fast, or ten times as fast, then the open source devs would look like idiots. If the open source ones are ten percent slower, then 99% of people will be completely satisfied. Games are flashy, and they sell cards, and people will complain about getting killed by somebody with a faster machine because it couldn't possibly have anything to do with lack of skill. In Blender, you just need sufficient speed to work. If the guy next to you has an extra 2 fps, it doesn't make him appreciably more productive, and you certainly can't justify needing to display faster than the refresh rate of the monitor in Blender!

Not lame at all.

It's actually quite nice when they tell us how to write our own drivers, so we're not dependent on them for needed maintenance (bug fixes, updates for newer kernels, etc). Companies can have all sorts of reasons to stop supporting a product, or to provide sub-par support, and being able to write our own drivers means that that isn't a problem.

What's left?

So what's left before the complete documentation sets are in our hands?
