    Phoronix: AMD Publishes Evergreen Shader Documents

    Yesterday some R500+ PowerPlay code was started on (but not yet usable), and now at the same time we have more exciting AMD news to report. AMD has just released their shader instruction set documentation for the R800 "Evergreen" graphics processors!This PDF document is available from AMD's developer area and is entitled "Evergreen Family Instruction Set Architecture - Instructions and Microcode." This documentation that covers their very latest GPUs in the Radeon HD 5000 series (like the Radeon HD 5750 and Radeon HD 5770) is important since its required for having the knowledge to provide 2D, 3D, and video acceleration for these newest Radeon graphics cards in the open-source Linux driver.In regards to the open-source status for the ATI Radeon HD 5000 series graphics cards, with AMD's internal open-source code-base they do have VGA outputs continuing to work with these Evergreen GPUs, but digital outputs continue to be troublesome -- though they are making process...

    The only half-way decent X drivers that I've ever had were the nVidia proprietary ones, and more to the point th eonly useful GPU drivers I've ever had were nVidia drivers on ANY OS...

    Oh, and let's not even talk about their weird OEM arrangements under windoze where they can't publish generic drivers... but then again nVidia and Intel don't compete against their own OEMs...

    ATI is a joke, and their spec release is a soporific for linux users who are not institutional users, nothing more. Although I will say that ATI's best hope of survival is to provide OSS drivers since they're dropping arch support like flies...
    You are completely right, no one other than nVidia can make usable graphics cards or drivers. What can I be thinking being satisfied with the ability of the Intel card in my laptop to display Firefox, Pidgin, and Skype?! I have been so misguided! </sarcasm>

    At least 90% of the world doesn't care about openGL, FPS, or any of that stuff, what they care about is cheap flights and package holidays, their daily viagra bidding wars, and the ability to edit wikipedia to prove their world view. For those, even the nv drivers are adequate. So describing nVidia as the only company producing usable GPUs + drivers is, frankly, comical. Intel are the biggest selling graphics vendor for a reason: they are dreadfully boring graphics that just work fine for everything but the gamer/enthusiast market.

    On the subject of ATIs FOSS drivers... IIRC, bridgman has said they are surprised at some of the performance they are already seeing from those drivers. To describe them as a sop is, again, laughable, as where they work they are, for the average user, far superior to nVidias offering, because, you know, they are just shipped by every distro with no legal issues.

    I am, currently, still holding off on embracing ATI drivers for a while longer, because I want to give them a bit more time to mature, and also because I'm not shopping for a new laptop or desktop. I think we still need to give the ATI FOSS drivers time, they have come a long way in a short time, and the graphics stack is changing around them...

    Maybe in another year it will be "Why did we ever doubt nVidia?", it could also be "There is only one high performance graphics option on Linux, and it's ATI". It really depends on performance of the FOSS drivers, and how close they an get to fglrx on the FireGL cards. As they say "We live in interesting times".

    In two years time ATI will probably be the only manufacturer left who's able to deliver high-performance graphics with free drivers. I am definitely supporting them and not Intel.

    Sorry, perhaps I missed something. Where in the document does it say "this document is only to be used for implementing opensource OpenGL drivers" ? The shader core supports DirectX, OpenGL, DirectCompute and OpenCL, and this document will be used as a reference for compute developers as well as graphics developers. The ISA docs are actually written and published by the Stream Computing team inside AMD, and our group writes the graphics-specific documentation.

    "are legal" in this context means "are valid", ie "will work". The other settings won't work in Germany either
    ok thank you... Galium3D-directx-stage *G*

    valid legal will work...... ok....

    settings again the law.....

    "not all possible settings for all fields are legal. This document specifies the valid combinations."

    i wana set settings again the law LOL

    i think.... in Germany this not legal stuff is not realy again the law...

    pdf-browser plug-in is broken :-(
