An anonymous reader writes "After 50 days of the Phoronix editor-in-chief exclusively using ATI Radeon hardware in his system, he has issued his final blog post dubbed The State of ATI Linux. Topics covered include the very low frame-rate performance, image quality, overclocking X.Org 7.1 support, Big Desktop/Dual Head, Linux CrossFire, and other relevant items to gamers and Linux enthusiasts. From the article 'While discussing this trial with a colleague that was not familiar with the quality of ATI's Linux drivers he immediately classified ATI Technologies as attempting to fine-tune a hull on a ship while there is a giant hole in the side. However, is this truly the case?'."

It's amazing to me the author of the article can put out as much verbiage as he did about this issue without ever once mentioning the real problem here - ATIs refusal to document the card interface so that the hardware can be properly supported.
Until they do, their customers that use Linux, *BSD, etc. remain broadly unsupported. Only a small subset of free systems even have the option of using the mushware they want to substitute for documentation, and at a cost many will not pay. They're making themselves irrelevant in what is probably the fastest growing segment of the computer market. Why would a free software user shell out big bucks for the latest ATI *or* Nvidious card only to face the choice of running it without accelleration for the same performance as a much cheaper card, or with buggy opaque mushware that that doesn't perform that much better and taints your system, assuming it will even run on it, which it often won't?

The hidden premise here is that somehow documenting the interface will make it easier for competitors to 'steal' some advantage. That's so obviously wrong in so many ways it's shocking someone would assert it in good faith.
What are they going to do? Copy the interface so their card will be compatible with the other cards drivers? Well, yes, I suppose someone could do that. Wouldn't necessarily even be a bad thing (standard interfaces are generally considered a good thing, even ad hoc standards.) But this is a far cry from somehow "stealing" the actual video card technology. That technology is, in many cases, patented, rather than protected as a trade secret, so the competition can (and you can bet, has) gone and read the patents right off anyway. They just can't legally imitate it too closely. And to the extent there are things in hardware that *are* trade-secrets, a disection of one of the cards would be a much better way to get at them. Looking at the external interface is the last method one would use to try to disect the inner workings of a device. Note that refusing to disclose the interface doesn't do jack to stop the competitors from disecting the hardware.
No, I'm sorry, that whole line of argument is utter nonsense.

How is not documenting the registers going to prevent NVidia from putting an ATI chip under an electron microscope to analyze their circuits?
Face it. If you're one chip fab competing against another one, documenting the externally-exposed registers for programmers is NOT going to deter your competitors in the slightest, nor is releasing binary-only drivers. Remember, decompiling code for reverse engineering IS l

And I really really truly regret it.
The main purpose of this computer was TV-Out, a feature only supported by the proprietary firegl drivers. The version I first got (8.16.20) didn't feature any overscan controls, so it sat in the middle of our television. After a couple of releases of this, we got 8.21.something which broke it even more - in fact, now you could only see the top third of any video you were watching with XV. At the same time of course, there was no 3d support at all.
Since then, I got a VGA->RGB Scart cable, and I've been able to switch back to the free drivers. The quality is significantly better - working 3d, a full screen picture and snappier menus. I plan to be very very careful when buying ATI again.

After learning exactly how "awesome" ATI's driver support was when I tried to setup 3D with my Radeon 8500 (and also Xinerama, etc) to play WoW under Cedega, in both 32-bit and 64-bit modes, I switched to nVidia and haven't looked back (yes, nVidia's drivers ran with Cedega and WoW in both 32-bit and 64-bit Linux installs perfectly well).
So, I suggest to you, to never buy ATI again. Saying you'll be careful when buying ATI again, is like saying you'll be careful when shoving a live scorpion into your pants again. ATI is shit. Regardless of what their hardware might do, if you don't have drivers to make it do it, it's the same as not having the card!

ATI bad under linux, worse under windows (Score:3, Interesting)
Way back when, I had my old box set up as a dual-screen, dual-boot (linux/win98). 1 ATI card, 1 integrated video card. Both linux and Windows had no problem using both cards.
Now - upgrade to a better box, throw in a Radeon 9200, and nothing works properly except under SUSE. Ubuntu, for example, insists on using only the PCI card (doesn't matter which one you have configured as the primary in the bios, PCI or AGP).
So, throw on a copy of Windows. Ha - the situation is worse. W2003 uses the 9200, but in 4-bit "colour", 800x600 res. The other ATI card is invisible to the system. Installing the drivers - oh joy - they refuse to install. XP Pro? No real diff.
SuSE 10.0, on the other hand, saw and configured both cards. However, trying to install ATI's drivers under both Ubuntu and SUSE failed - the install program craps out.
When it comes to video cards, from now on ATI means "All Time Ignore". I didn't have these problems with the old GeForce 2 with TV-out that worked perfectly.

ATI on-going POOR support of the Linux community (Score:3, Informative)
On of the first attempts by ATI to provide an actual ATI supported package for Linux was the VHA Kit. This was supposed to be a library/SDK made by ATI and Loki Games to allow Linux access to the Rage chipset support for hardware assisted decompression of MPEG2 so that iDCT did not need to be done in software. When I have asked ATI about the VHA kit and if they have any commitment to providing on-going support for hardware assisted iDCT for Linux, they claimed that the kit was never distributed because of lack of interested in the community. This seems really fishy since release of the kit even made it on Slashdot and there where several comments at the time expressing interest. Later, a former developer from Loki stated that do to limitations in the Rage chipset implimentation of moving data back and forth, it was faster just to do iDCT in software.
Then the Radeon came out which should have addressed the limitations in the Rage. And nVidea released their closed source drivers with iDCT. While it is possible to do iDCT in software for the 480i resolution of DVDs, for HDTV tuners such as pcHDTV, a nVidea card is almost a requirement to view 720p and 1080i MPEG2 streams. ATI got so many requests for iDCT support that they put online a FAQ on their support site claiming that Gatos was working on the issue. In reality, the Gatos mailing list had posted multiple times that they where not working on iDCT at all. When I contacted ATI requesting to get the Radeon specs needed to support the iDCT support myself, they stated that such information is *NEVER* released outside of ATI. They went to explain that even if the developer signs a NDA, they still will never release the specs to do iDCT support.
Then the All-in-Wonder 8500 which was supported by Gatos was discontinued so I contacted ATI to offer my help to work on Gatos support of the All-in-Wonder 9700. They ask me to be patient and they would be getting back to me. A couple *YEARS* later and they still haven't gotten back to me. According to Gatos, they have gotten around to providing the specs and example hardware to one of the developers. But while Gatos is "open source" in the fact it is GPL, no one else can be much help to the project since the Gatos developers can't legally give the specs to any potental developers. All they can do is tell potental developers to contact ATI which result again with a request to be patient for *YEARS*.
The All-in-Windows 9700 is now discontinued and the new mainstream AIW card is the AIW 2006. Gatos doesn't even claim to have been provided any specs for this newer card. The ATI prioritary drivers provide no support for the tuner at all. And ATI continue to blow off requests from any potental developers except for the ones they already have an established relationship.
And for some reason that eludes me, people still claim that ATI does a better job of supporting the Linux community than nVidia! Does ATI's drivers provide iDCT support for Linux? nVidia's drivers do. If you call ATI right now asking for driver programming specs for any shipping Radeon chipset, do they actually provide it or tell you to just wait (and wait and wait and wait)? nVidia is at least honest about what programming specs they will openly release and what they won't.
