AMD Releases Open-Source R600/700 3D Code 307

Michael writes "AMD has just released code that will allow for open-source 3D acceleration on their ATI R600 and R700 graphics cards, including all of their newest Radeon HD 4xxx products. This code consists of a demo program that feeds the commands to the hardware, updates to their RadeonHD driver, and a Direct Rendering Manager update. With this code comes working 2D EXA acceleration support for these newer ATI graphics processors as well as basic X-Video support. AMD will be releasing sanitized documentation for these new ATI GPUs in the coming weeks. Phoronix has an article detailing what's all encompassed by today's code drop as well as the activities that led to this open-source code coming about for release."

    This seems to confirm what people have been predicting all along, that OSS philosophy is driving competition between vendors to cater to their customers' needs. Nvidia, Intel, and now ATI all providing increasing levels of documentation and code support in competitive volleys. I for one welcome our new 3d accelerated overlords.

      Er, what exactly is Nvidia doing in this regard? They've put out more or less OK closed drivers for Linux for a number of years now but they go out of their way to frustrate FOSS efforts. The "open source" nv driver is obfuscated. About all you can say about it is that it compiles to a basic 2D driver.

      Intel releases fully realized drivers and some docs. ATI/AMD is releasing ever more complete docs and more or less cruddy closed drivers. With the help of Mr. Weite, VIA is starting to release docs and is co-operating with current FOSS driver authors. I don't see Nvidia doing anything of this sort.

      • I thought I recalled reading something recently about Nvidia releasing more documentation on their video decode acceleration, but looking back through my browser history I think i may have created a composite memory based on an intel article and Nvidia opening an API for video decoding using their closed source driver. Either way I can't imagine that Nvidia is gonna be able to leave us out in the cold much longer on this front. Keep voting with your wallet and we'll see them change their tune soon enough.

          I just recently bought a Dell laptop. It came with an nvidia card -- no option for ATI. What's more, this is all new stuff -- as far as I can tell, the closed nvidia drivers are still better than any ATI Linux drivers, but that may have changed.

            The parent has pegged a round hole with a square question. Hardware support in Linux works well if you build your own machines, or happen to get one with supported hardware. How do you find a system that is fully supported and for which distributions?

            This is still a problem for F/OSS software. Some distributions are better at handling the problem than others. For many end users, finding a proprietary driver and installing it on Linux is a deal-breaker.

            I'm glad to see that ATI is moving toward support for all OS software, but it still leaves the general community with a problem. That problem won't go away until hardware manufacturers support F/OSS out of the box. It means changing their model and prospective future business plans to some extent.

            I'm willing to bet that if everyone who *REALLY* wants to see great F/OSS drivers for ATI were to plop down $5 USD it would make a difference to how they are thinking about releasing drivers. Yes, $50,000 might not be much but it also might make a difference to ATI. This falls into a category of donations that I've talked about before.

            Finding who to donate to is not always easy since many apps are hidden from the user, such as Samba, drivers, etc. It would be good if there were some place people could just drop a donation for the distribution they are using and feel safe that some percentage of that went to all those apps that are part of the distribution. This always brings up some heart felt discussion, but I think something like this is an awesome thing that would help drive better development for F/OSS software. See, getting $1.75 per user is a lot of money to some F/OSS teams. Hell, even fifty cents would be a lot more than they are getting now. So a donation of 50 or 75 bucks could mean a lot to many people. I try to donate to the apps that I use the most and I KNOW how difficult it is to do that.

            If anyone is interested in progressing such a thing, contact me. I can probably find some time to donate to this as a project.

That is to say that whatever donation option I choose, I should be able to annotate that it is for xyz number of systems, and the site/service would add that up for me so that I don't have to go through the process 8 times. Even two times would be tough going for

                  Which means the apps on that distro disk will be chosen by who needs the money, or who's paid the bribe, not which app I actually need. What's more, even if done properly, it will have a bias towards hardware autodetection, disk compression, hacks like unionfs, installation, and recovery tools -- things like ntfsresize and friends.

              Anything with an Intel Centrino logo /should/ have a full array of linux supported hardware. The intel centrino chip "package" includes wifi, video, cpu, acpi, sata, and sound all with known working mainline kernel supported hardware. Not that I work for or endorse their products necessarily, they just happen to be the only vendor who has bothered with providing the code, documentation and (in the case of their wifi chipset) firmware for all the same hardware that they include in their logo certification program. Probably not the top of the line hardware, especially the video, but it's hard to argue with a product that fits so neatly into the HCL for any recent linux distro.

    I am looking forward to see what this means for Linux, OpenCL and other GP-GPU goodies. With OpenCL working along side OpenGL, a tightly integrated kernel ATI driver that handles the GP-GPU/OpenCL stuff we will really see some interesting stuff come our way. To my understanding OpenCL allows someone who is writing an algorithm to implement it in OpenCL and let OpenCL take care of diving up the work load between GPU's and CPU cores. Damn I am really excited to see the OSS community tie all this stuff together and release the computing power of the GPU to more general yet compute intense applications.

    A system with a quad core CPU and four ATI cards would be a force to be reckoned with! Fast trans-coding/cracking of Blu-ray, rapid key sniffing for air crack, even networked applications could be sped up like IPsec and SSH. We could have fast rendering in blender and ray tracing can be done with high precision as well as speed (maybe even real time!). Gimp plug-ins can be given a boost in speed and video editing a breeze. Even a laptop with a slower dual core could benefit from its on board GPU's number crunching power. Useful for cracking WEP/WPA keys.

    And AMD/ATI arent the only ones getting on board the OpenCL bandwagon, Apple developed it, and Intel along with Nvidia are also going to support it. So OpenCL will allow us to run our apps on the hardware of our choice.

Being able to pan the camera around and view it literally from another angle or have more complex movies with multiple things going on. Being able to focus on a couple's drama or watch a car chase on the other side of town (all within the same "movie".)

    Q: So why is there only code for radeonhd? Will radeon support this too? Why two separate drivers?

    A: The reason for two separate drivers is a very long and largely silly story. I don't feel like repeating it, and I probably couldn't tell it fairly anyway.

    I'll get radeonhd code ported over to radeon once my vacation's over, assuming nobody does it sooner. I can't do the HDMI audio setup without testing hardware, though; does anybody want to donate an HDMI audio-enabled monitor? :3
