Insight Into AMD's Linux Driver Development

Posted by CmdrTaco on from the they-should-all-wear-hats-while-they-code- dept.

Cowards Anonymous writes "It's no secret that ATI Technologies has had a rough time in the past delivering display drivers that met the expectations of their customers. When ATI started out producing a FireGL and Radeon Linux driver they for some time were greatly behind NVIDIA's feature-rich driver. The early ATI Linux driver had lacked essential functionality such as PCI Express and x86_64 architecture support and was also affected by stability and performance problems — not to mention a great deal of bugs."

    It's also no secret that ATI has long had problems with their drivers for Windows too.

    No, this is not a troll. I use ATI cards almost exclusively myself and I prefer them over NVidia, but I do have to admit that Nvidia's drivers as a general rule seem much better designed and simpler to install.

      Not sure what kind of "supporting evidence" you might want, but I once bought a Radeon once to replace my aging Voodoo3. I forget the exact model number, but at the time it was about $175 or $200. In some games it was *slower* than the Voodoo3. I gave up and reinstalled Windows clean, but still had the same trouble. Took it back, got a GeForce 3 Ti 200 for about the same price, and it worked beautifully out of the box. Fast forward to several years later and I was looking to replace that card, and I got another Radeon. Installed the drivers, slapped in the new card - poof, blue screen on boot in the video drivers. Stuck the GF3 back in, removed it from the DevMan, and manually installed the VGA driver. Rebooted with the ATI, installed the drivers - back to Bluescreen on Boot. So, another clean install of Windows, and still got bluescreens on boot. Took that Radeon back and got a GF 6600GT again for about the same price, slapped it in, and it's worked ever since. I have a hard time believing I had other bad hardware in there to cause the troubles since in both cases the GeForces worked perfectly. Not to mention the GeForces worked much more nicey in Linux than the Radeons ever did. I genuinely gave ATI two tries now, and both times I was hit with troublesome drivers. I doubt I'll be buying another Radeon anytime soon.

  3. The best way... by twoboxen · · Score: 5, Insightful

    to build a customer base is to alienate your existing customer base. I bought an R200-based laptop a couple years ago. ATI decided to just not support those cards in their fglrx driver package one day. Why would I buy from a company who won't continue support for their own products for more than a couple years? I will make every effort to never support them again until they get customer/product support in order. NVIDIA, bravo.

      If you're using some sort of Linux/*BSD/etc, you shouldn't have to worry because X.org has had mostly full and useable R100, R200, and recently R300 open source drivers for quite some time now. They're decent. I've been playing Unreal Tournament (and variants) without problems. The only issue is visuals with Doom 3 do to S3 Texture compression being patented. If you're using Windows, well good luck!

  4. what a joke by radarsat1 · · Score: 5, Insightful

    While ATI/AMD is working steadfast in addressing all of these issues and further enhancing their level of Linux support, many of their customers do not realize all of the work that goes into these drivers.


    Whatever. They don't need to do any work. All they need to do is open up the specs, and people will do all the work for them. People aren't bitching that the drivers don't work, people are bitching because they aren't allowed to improve them.

    There's a whole community out there willing to do all the software work from scratch, but they don't have the resources to create the hardware. The hardware developers somehow see this need to provide the software themselves, instead of taking advantage of the community, but then go and do a shoddy job of it. That's why people are annoyed by the whole thing. It could be so much better, with very little effort from ATI, but they steadfastly refuse to play nice, forcing developers to resort to reverse engineering. Same goes to Nvidia by the way, but at least they seem to be a bit more competent in Linux/X.org driver development.

    This whole argument is just a big excuse. We don't want excuses, we want some damn drivers.

      Bingo.

      When hardware companies try to make software, the result is almost inevitably shit. There are some exceptions, but big hardware companies tend to see software development as a 'cost center,' an afterthought to be minimized as much as possible, rather than a critical and major part of their product.

      Look at scanners if you want. I've used some great film scanners in the past; brilliant hardware engineering, but coupled with the absolutely shit software that came in the box with it, it was practically a doorstop. To get anything else done, you had to get VueScan or Silverfast -- addon software written by people for whom software is their primary focus.

      It's also possible (and likely) that they are violating patents they don't have a license for, so giving the specs out might bring light to this. A stupid legal reason rather than a technical reason...

  5. ATI and Fedora 7 / X.Org 1.3 by harrypelles · · Score: 5, Informative

    I made the same mistake as many Fedora users - jumping (to Fedora 7) before looking. I'm not poking at Fedora here, on the contrary, I am a loyal Fedora user. It's ATI I'm upset with. ATI released a new fglrx driver (version 8.37) since Fedora 7's tests and final release that also does not work with X.Org 1.3. We're all sitting around waiting for the 8.38 which ATI claims will be compatible. And don't even get me started on ATI's absent AIGLX support for Linux. My next card will nVidia.

      The difference is that here Vista is to blame, while on Linuzz everyobody magically undarstand that this is a driver's problem.

      Perhaps because 'Linuzz' is open it is easy to see where the problem lies. With Vista you get huge binary blob and if it's broken you don't know if it is the drivers or Vista -- you can't debug it and look at the source so you call MS tech support and wait 6 months for a service pack or MS tells you to call ATI/AMD and you wait 6 month for a fix. Binary drivers suck that's the problem here...

  6. Nothing to see here. by BESTouff · · Score: 4, Insightful

    Basically, TFA says that "ATI has a release cycle". They even have an unofficial bugzilla and an unofficial wiki. Oh, and they'll drop R200 support too. And all that's supposed to make better drivers for Linux one day. I really wish they'd go the Intel way: hire some top-notch developers, give them specs and make them do Free drivers.

    Actually, Intel has not released docs for their GMA X3000. Their current stance is that the driver is the documentation. That's fine and good, except the driver is still very incomplete (missing OpenGL features, no XvMC, no tv-out, etc.). See here:

  9. nVidia blob isn't crap. by gukin · · Score: 4, Interesting

    I know that lots of folks are vexed that nVidia won't open their 3D driver, saying "If nVidia stops supporting Linux you're all doomed." Well just who do you think supports the open source nv.c driver? How about the nVidia SATA driver? Yes, it's nVidia, so even though the 3D stuff is closed source, they're still supporting OSS.

    Next about the "Crap" drivers from nVidia, I've ordered a bunch of new Linux PCs, each will have a low-end nVidia video card added when it arrives? Why? Well I need dual headed support and that can be spotty with other video card vendors. I also need to run them in 8-bit color (don't ask, I just need to.) and my experience with the glorious wonderful OSS Intel video drivers is a nasty little box that follows the cursor around on the screen. I don't have ANY issues with nVidia's "Crap" drivers, everything looks great and works great.

    I applaud ANY vendor who makes efforts at supporting OSS but I buy stuff from vendors who support Linux. Every system I own is either an nForce mobo with an nVidia video card or is simply sporting an nVidia card. When asked about what to buy, I recommend nVidia products. They have the best quality 3D support and performance of ANY vendor (which isn't much), they make it possible for me to play games under Linux that I'd otherwise have to play under Windows and that is worth a lot to me.

    Everything works? So you can use Firefox at a reasonable speed when logged in as a second user now? You can use Beryl now? Those things sure don't work on the X1300 I bought (a horrible mistake) a couple months ago.

    It's really absurd - if they'd just release the programming info for their hardware the X.org drivers would support this stuff inside a week.
