AMD's OverDrive and CrossFire Come To Linux

Posted by timothy on Wed Aug 20, 2008 02:15 PM
from the first-they-laugh-then-they-create-drivers dept.
twljagflba writes "Since last year AMD has made ATI increasingly Linux friendly by releasing 3D programming guides and helping out the open-source community. At the same time they have been continuing to develop their binary Catalyst driver for the Linux platform and most recently they delivered same-day support for their new graphics cards. Today though they have released the Catalyst 8.8 Linux driver that adds two very important features: CrossFire and OverDrive support for Linux. Linux users are now able to use CrossFire to split the rendering workload between multiple GPUs and they're also able to overclock their graphics cards now using the binary-only driver. Phoronix has a complete run-down on both features — including benchmarks — in their AMD OverDrive on Linux and ATI Radeon CrossFire On Linux articles. Other features were also introduced in this update such as Linux 2.6.26 kernel support, Adaptive Anti-Aliasing, and other fixes."

[+] 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."
[+] Technology: AMD's New Card Supports Linux From the Get-Go 352 comments
Michael writes "Back in September AMD had announced a new ATI Linux driver as well as opening up their GPU specifications, and today they have taken an additional step to better support the Linux OS. With the just-announced Radeon HD 4850 RV770 they have provided same-day Linux support, and the Linux driver is now shipping alongside the Windows driver on their product CDs. In addition, they are encouraging their AIB partners to showcase Tux on the product packaging as a sign of Linux support. Last but certainly not least, AMD is committed from top-to-bottom product support on Linux and they will be introducing high-end features in their Linux driver such as MultiGPU CrossFire technology. Phoronix has a run-down on AMD's evolutionary leap in Linux support along with information on the open-source support for the RV770 GPU."

    I've got to say I'm disappointed they don't provide Crossfire numbers for the same hardware on Windows. It's nice that Crossfire can improve things in some situations and some games that are supported under Linux, but I'd like to know the relative benefit.

    That is, when going to Crossfire do both Windows and Linux gain 40 FPS? Or do they both go up 60%? Or does Windows go up by 70% to 100 FPS where Linux only goes up 40% to 80 FPS?

    How close are they? That's what I'd like to know.

    I also find the "we had no problems except for some segfaults during Quake Wars, and they say that will be fixed in a month or two with the next version" a little worrying. A problem with a driver is a game looking off, or having slow frame rates. Segfaulting the system is not a problem, it's a BIG PROBLEM.

    • did it say the /OS/ segfaulted? I'm pretty sure I had apps segfault in Linux without taking the OS down with them. Admittedly it's been a while since I've used Linux (about a year?), so I can't remember for certain.

      • Yes segfaults affect the application only (unless the kernel itself segfaults, which never happened for me). Although if it's a driver that segfaults it may bring down the system, I think if it's built as a module and not compiled into the kernel it shouldn't
        • Being built as a module makes it no different from an in-kernel driver once it is loaded. A crashing driver would have the same effect whether it's a module or not.

        • True, if the video driver segfaults, it'll only take down the display. You won't be able to see anything, but other than that, the system will be fine.
          • If you are logged in via kdm/gdm/xdm, it will also log out (at least in FreeBSD, the intel driver on my notebook has done that to me a couple of times in an older version of xorg).

            Still, that's annoying, not a system crash.

    • Gaming usually better on Windows, since DirectX actually uses the new features on the GPUs where as Linux's OpenGL hasn't evolved quite as much, since it is primarily used in proprietary 3D CAD programs, which requires a stable codebase.

And whether someone will buy nVidia, Intel or ATI graphics for Linux depends upon their preference for powerful but proprietary binaries, free software compositing and low power consumption or the choice of reasonable performance in ATI's binaries or high-performance free software from the X.Org drivers.
