Last September AMD had provided an open-source AtomBIOS parser for use by the RadeonHD driver in order to communicate with this video BIOS abstraction layer found on the past few generations of ATI graphics cards. While we are still waiting on the R600 sample source-code and 3D register documentation to arrive, AMD has today released a new AtomBIOS parser. This parser is coming out of their KGrids project, which we have previously mentioned in the past, and will allow for a clean AtomBIOS parser to enter the Linux kernel.

In recent times, the xorg.conf file once used for configuring all static X-related server options has been shrinking in size. Thanks to more reliable EDID (Extended Display Identification Data) on LCD panels, it's generally no longer needed to manually specify mode-lines within this X.Org configuration file. With improvements for auto-detection, in many circumstances it's no longer even needed to manually specify your graphics driver and other options. However, the X Server currently lacks an infrastructure for supporting persistent device properties.

Since last night's release of Ubuntu 8.10 Alpha 2 we have been trying out this latest work from the Canonical camp. While many Linux desktop users would just shrug off X.Org 7.4 as not being too relevant to them -- considering there aren't that many new blatant features -- if you're a faithful Phoronix reader you should already know about much of the recent driver work (especially on the ATI side) and Mesa advancements along with X Server fixes.

The Novell developers behind the xf86-video-radeonhd driver have yet to receive their hardware samples from AMD for the Radeon HD 4850 or Radeon HD 4870, but there is already AtomBIOS-based support for these next-generation graphics processors. This open-source driver now has basic mode-setting support, but the 2D and 3D work is still to come.

We've talked all too often about AtomBIOS and there being two different open-source drivers that support the same ATI Radeon hardware with the key architectural difference between the two just being the use of this video BIOS abstraction layer. From the beginning, AMD was planning to have their Novell partners use AtomBIOS when writing this new (at the time, R500/600) driver, but the developers ultimately declined. These developers have expressed their opinions on AtomBIOS, which range from it being an unbearable mess to this design being nothing more than writing open-source code to power someone else's closed-source work. However, under pressure by AMD, the developers are now preparing to use AtomBIOS to a much greater extent within the xf86-video-radeonhd driver. In this article we'll tell you more about what's gone on and where you can checkout this AtomBIOS-bearing RadeonHD driver.

Now that we have delivered OpenGL benchmarks of the ATI Radeon HD 4850 on Linux, we are turning our focus to the flagship Radeon 4870. For this testing we have dual Radeon HD 4870 graphics cards from Sapphire Technology. We'll be publishing these initial results in the coming days, but for now, we are just letting everyone know that this RV770 GPU also is working with xf86-video-ati after writing a trivial patch for this display driver. Our patch is enclosed.

In our article this morning entitled AMD Makes An Evolutionary Leap In Linux Support, we briefly touched on the fact that AMD would be continuing in their open-source support for the Radeon HD 4000 generation of GPUs. AMD will release register information for the RV770 and the code to TCore and KGrids will help the community developers when it comes to 2D and 3D acceleration. Though, with not much work at all, this afternoon we have the ATI Radeon HD 4850 512MB running with the open-source xf86-video-ati driver! The Radeon HD 4850 will not currently work with the xf86-video-radeonhd driver as it doesn't rely upon the AtomBIOS in these areas, but in this article we have enclosed our patch and other information for using this open-source driver on AMD's latest hardware.

Less than a year ago we shared with you the revolutionary steps AMD was taking to deliver significant improvements to their once infamous proprietary Linux display driver and at the same time the work they were doing to foster the growth of an open-source driver for their latest graphics card families. These steps have certainly paid off for both AMD and the Linux community at large. AMD's proprietary driver is now on par with NVIDIA's Linux driver and there are two open-source ATI drivers picking up new features and improvements on an almost daily basis. AMD also continues to publish new programming guides and register information on a routine basis for their latest and greatest hardware. This has been truly phenomenal to see, but AMD has now evolved their Linux support by taking it a large step further. AMD is in the process of pushing new high-end features into their Linux driver -- such as Multi-GPU CrossFire support -- and with the ATI Radeon HD 4850 they have even begun showing off Tux, the Linux mascot, on their product packaging and providing Linux drivers on their product CDs!

In AMD's usual fashion, this afternoon they have announced the release of new display drivers for both Linux and Windows. The Catalyst 8.6 release for Linux introduces a few bug fixes, version 2.0 of their driver installation API, and a few unannounced features are present. As always, we have the run-down for you on this month's changes.

Following our article looking at the state of X.Org (along with announcing the release of X Server 1.4.1), we proceeded to share the contributors behind the X Server -- both the individual developers and companies involved with fostering the growth of this important free software package since 1999. What we hadn't looked at in that analysis was the people and companies behind the work on Mesa 3D, or the OpenGL component used by X. In this article, however, we have these statistics to share.
