An anonymous reader writes "Ending off the X Developer Summit this year, Matthew Tippett handed off ATI's GPU specifications to David Airlie on a CD. However, the specifications are also now available on the X.org site. Right now there is the RV630 Register Reference Guide and M56 Register Reference Guide. Expect more documentation (and 3D specifications) to arrive shortly. The new open-source R500/600 driver will be released early next week."

Linux: Future AMD GPUs To Be More 'Open-Source Friendly' 180 comments
skaroo writes "Phoronix is reporting that future AMD GPUs will be more open-source friendly. After AMD started releasing their GPG specifications to the open-source community, questions arose whether there would be information covering the Unified Video Decoder (UVD) found on the Radeon HD 2000 graphics cards. The UVD information is needed in order for hardware-accelerated video playback, but it likely cannot be opened due to DRM. However, an AMD representative said that moving to a modular UVD design is a requirement for future GPUs and that they will be more open-source friendly. They will also be opening the video acceleration information for their earlier graphics cards."

AMD Releases 3D Programming Documentation 94 comments
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."

I'll replace my nVidia when I see a good review. (Score:5, Insightful)
I'll do my part and replace my AGP nVidia card with an ATI one as soon as there is a good review of an available card with this driver on Ubuntu.

And the Windows Vista driver sucks, somewhat hilariously.
It wasn't too long ago that I was at Microsoft's Philadelphia offices for an Exchange 2007 presentation. The first thing that they wanted to show was a short video on a projection screen -- what they actually showed the audience was a Vista laptop with ATI graphics choking half way through a two-minute video and then puking an error message saying that the video driver crashed and was being restarted. And some guy behind me said "Twelve years later and they still can't get the presentation right."

I've been recommending nVidia cards to everyone who asks, simply because their Linux support has been leagues ahead of ATI (now AMD, for those who haven't been paying attention). If the specs are credible enough to create a quality Free driver, then I'll switch to AMD in a heart beat.

So you'll probably want to wait and watch until the driver is ready to go and up to whatever performance and stability standards you need for your application. Switch now and you are likely to find yourself in essentially the same situation as before: ATi's binary driver, or an OSS driver that doesn't do what you want.
It'll be some time before this information can be transformed in to a fully functional, stable, fast driver. After all, if it were so easy, ATi and nVidia would have perfect drivers out on the launch of a new card and never need to do anything but minor updates.

Because Linux is less resource intensive, he's able to upgrade his distro several times on the same hardware, putting himself in the situation of having a new kernel with old hardware and old drivers that don't load in the new kernel.
If you want to upgrade Windows, you usually wind up needing a new machine, so: new machine, new video card, new drivers, new Windows -- not a problem. Well, at least not the same problem.
So it's not an issue of what's *wrong* with Linux, it's what's *right* with it. The problem is that this presents circumstances the hardware world isn't used to dealing with.

Google realized this early, and bought off a great amount of geek awe by using Linux as the basis for its computing grid. This popularity among geeks turned into word of mouth advertising which turned into huge market share (having a great product didn't hurt either). Google still tries to maintain the "we're just a benign bunch of geeks" image (an image which is eroding, as it becomes more apparent that they are more akin to a lovechild of M$ and the NSA than a giant sushi eating LAN party). This appeal to mindshare by making steps toward the community, genuine or not, may be part of what AMD is trying to do, at least to an extent.
There are other genuine benefits to being more open about its specs, most clearly highlighted by the use of ATI GPUs to process Folding@Home. Therefore it is conceivable that AMD GPUs and GPU/CPU combo chips in the future may, if more openly specced, be used in a wider variety of HPC applications.

AMD ie recently making more moves toward the open source community than either it or ATI did prior to the merger.It seems to me that AMD has realized that there is value in not only having the right products rolling off the lines, but also having a greater mindshare.
AMD has actually been making moves for a long time so this isn't as large a step for them. Even before the amd64 cpus came out AMD had specs available and a machine simulator as well as several kernel developers working on getting Linux to run on their hardware.
On the other hand this is a huge step for ATI and I may very well find myself reconsidering my ATI boycott.

This conspiracy theory seems incomplete. Did Jimmy Hoffa steal the search technology from Area 51's crashed Roswell UFO, and masqueraded as JFK when FSF supporters attempted to assassinate him for creating the possibility of a faked Apollo moon landing, then went into hiding for many years as Lord Lucan, fathered Princess Diana's unborn child, found Elvis and Marilyn Monroe alive and well in Atlantis, flew an Aurora spy-plane powered by water-fuelled engines through the hole in the North Pole into an unknown hollow Earth down to the South Pole, took this fabled Google search technology to the secret Illuminati base in Antarctica before heading north again, annoyed the Pope and Opus Dei and the long-lost descendants of Jesus Christ and finally became integrated into the Project for a New American Century's headquarters, the NSA - which was almost obliterated when the international Zionist conspiracy felled the Twin Towers with explosives and thermite in the fraudulent September the 11th attacks?
To be honest, you're not trying very hard. Or giving the real-world NSA lots of credit and assuming no end of competence on their behalf. They've cracked every form of encryption as well, right?

NVidia have been stalwart protectors of their hardware designs, mostly due to historical accident. A few of the principals at NVidia used to work at Sun, where they designed the GX graphics chip. As it turns out, a version of SunOS was released with a header file describing the chip's registers. Using that -- and a logic analyzer -- a company called Weitek successfully created a functional clone of the chip that was good enough such that Sun's own drivers worked on it. This stuck in the craw of the Sun guys, and evidently vowed no such thing would happen again.
Another historical accident was that NVidia did, in fact, have a few source code releases way back. And every time they did, so it seemed, they got hit a few weeks later with a patent infringement lawsuit, usually from SGI. NVidia solved this latter problem largely through the expedient of buying SGI.
So, no, I don't think they're going to do it, and certainly not within six months. And yes, I would be perfectly tickled to be wrong about that.
