For those following the xf86-video-ati developments or use this open-source Radeon driver for their graphics card, you may want to check out the latest development code. Committed to its git branch today was a lot of new work from Alex Deucher, Dennis Kasprzyk, David Airlie, Egbert Eich, and Corbin Simpson.

A month ago we had shared that the RadeonHD driver would be switching to AtomBIOS, or the ATI video BIOS abstraction layer used since their R400 series graphics cards, and today they have completed this code merger. The Novell developers behind the RadeonHD driver have long preferred the route of banging on the registers directly than relying upon this closed-source (aside from the open-source parser) framework, but they had folded due to pressure from AMD with the time it's taken to support new GPUs and the developers behind held up waiting on register documentation to arrive.

In time for SIGGRAPH 2008, AMD has announced the ATI FirePro series with the FirePro V3700 and V5700 being the first two products. However, unlike many of their FireGL graphics cards, the prices on these two announced FirePro parts aren't that bad. The FirePro V3700 will cost a mere $99 USD while the V5700 will be $599 USD. These new workstation graphics cards support DisplayPort, OpenGL 2.1, and PCI Express 2.0. The FirePro series will start shipping in September so we expect there will be Linux support for these graphics cards by Catalyst 8.11. More on the FirePro series can be found in the press release and FirePro product page.

Back in March we had benchmarked the ATI Radeon HD 3200, which is an integrated graphics processor (IGP) built into AMD's 780G motherboard chipset for use with Phenom processors (but is also backwards compatible with early AMD AM2 CPUs). We were pleased with the performance of the Radeon HD 3200 IGP, but today AMD has introduced the 790GX Chipset with Radeon HD 3300 graphics.

For the past two weeks we've been talking about the RadeonHD Command Submission branch that changes all of the driver's command sequencing calls into inline functions in order to offer dramatically improved performance. This branch of the xf86-video-radeonhd driver also presents a command submission infrastructure using the GPU's command processor (CP) for the R500 (Radeon X1000) series using MMIO (Memory Mapped I/O).

For those interested in playing with the latest open-source ATI code but don't want to dive into kernel mode-setting or the new AtomBIOS parser, you may want to test out the CS branch. The CS branch was started last week by Luc Verhaegen as it turns all calls made by the driver into macros. This was done due to GCC not optimizing the inline functions within the xf86-video-radeonhd driver on OpenSuSE, but now the performance of these calls is much more efficient. This driver branch also introduces a command submission infrastructure for R500 MMIO (Memory Mapped I/O) to allow the use of the GPU's CP (Command Processor) without depending upon DRM (Direct Rendering Manager).

Many Linux users will be celebrating the Christmas holiday in five months, but it seems there's a holiday worth celebrating today for open-source ATI Linux users.

There are already separate branches of the xf86-video-radeonhd driver for AtomBIOS support and another one for improved 2D acceleration, but today we have yet another branch. This new branch is called "CS" and what it does is change all calls within the driver for the command sequences (the "CS") into macros.

Since last month's release of Catalyst 8.6 for Linux we've seen the introduction of the Radeon HD 4850 and 4870 graphics cards and we've been allowed to share with you that CrossFire is coming to Linux along with other yet to be announced features. Today AMD has released the Catalyst 8.7 Linux driver and it doesn't deliver any new ground-breaking features, but it does bring a few improvements.
21 July 2008 - What About The New Features?
While AMD's financial outlook has been bleak with it closing down 12% today, if you're a Linux user -- particularly one with a quad-core Phenom processor -- there is good news to report from the AMD camp.

For those of you that have been using the open-source xf86-video-ati driver, need we remind you of its rapidly-improving state and feature set? One of the latest additions to this open-source ATI driver that supports the old ATI R100 graphics cards up through the new Radeon HD 4800 series (RV770) is tear-free acceleration. The current implementation of this tear-free acceleration is for EXA and Textured Video (X-Video) and should eliminate any "tearing" issues that some users experience. This code isn't yet found in the master branch of its development git repository, but can be acquired through the vsync_accel branch. Alex Deucher, the mastermind behind this latest code, has described this improvement on his blog.

This morning an embargo expired covering AMD's newest high-end graphics card, the ATI Radeon HD 4870 X2 (codenamed the "R700"). Like the Radeon HD 3870 X2, this new X2 variant just combines two of AMD's high-end GPUs on a single PCB and connected via CrossFire. The Radeon HD 4870 X2 with its dual RV770 cores aren't available today, but it will start shipping later this summer.

Earlier this week we reported on RadeonHD driver support for the RV770 with the Radeon HD 4850 and Radeon HD 4870 graphics cards. This support arrived within the RadeonHD driver's new AtomBIOS branch that relies upon ATI's video BIOS abstraction layer as opposed to "banging the registers" and interfacing with the hardware directly. However, the lead developer of the xf86-video-radeonhd driver has back-ported the RV770 support using these hard-coded paths.

The xf86-video-ati 6.8.0 driver was released back in February, and today version 6.9.0 has been released, which is coming just a day after its 6.9.0-rc2 release. Version 6.9.0 of this ATI driver adds improved EXA render support for R100/200 graphics cards, EXA render support for R300/400/500 graphics processors, and Textured Video support through X-Video for R100-500 graphics processors. This open-source driver supports all generations of Radeon graphics processors (aside from official support for the just-released HD 4850 and HD 4870). The complete change-log for xf86-video-ati 6.9.0 and source download links can be found on the X.Org mailing list.

While AMD still has yet to release any R600 programming documentation or the source-code to their KGrids or TCore simulators (though the documentation may finally just be days away), Alex Deucher and David Airlie have been working on R600 DRM (Direct Rendering Manager) support. Today the first bits of this DRI component for the Radeon HD 2000/3000 series is now available. Within the Mesa/DRM git tree at FreeDesktop.org is a new r6xx-support branch. This R600 DRM uses the CP (Command Processor) for communication, but before checking out this branch, be forewarned that 3D acceleration isn't ready yet. While there is open-source R500 3D support and it's working quite well, Alex believes it will be at least another month or two until the Mesa and DDX code is in place for this R600 3D hardware acceleration.

Twelve days after the first xf86-video-ati 6.9.0 Release Candidate, the second RC release is now available for testing. Since xf86-video-ati 6.9.0-rc1, the man page has been updated, a ShadowFB R600 fix, PLL tweaks, a possible fix for VGA on ATI IGP chipsets, warning fixes, cleanups, and other work. If you're interested in testing out xf86-video-ati 6.9.0-rc2 on your Radeon graphics card (up to and including the just-announced Radeon HD 4850/4870), this is a git-only release and can be cloned from git://anongit.freedesktop.org/git/xorg/driver/xf86-video-ati.

Now that there is a Stream SDK for Linux (related reading: AMD Stream Linux Q&A), if you're looking for a new solution for accelerating CAL and Brook+ development / stream computing, AMD has a possible answer for you. This morning in Dresden, Germany they have announced the FireStream 9250. The FireStream 9250 is also the first unit to break the tera-flop barrier! The first FireStream part introduced earlier was the FireStream 9170, which provides up to 500 GFLOPS of computing power. The FireStream 9250 will be available later this year at a price of $999 USD. More information is available in their press release.

AMD's Alex Deucher has today announced the availability of the documentation covering the R600 Family Instruction Set Architecture. This ISA (Instruction Set Architecture) documentation covers the unified shader block found on the Radeon HD 2000/3000 series and newer. This PDF document is 342 pages long and does go into detail surrounding R600 vertex and geometry shaders.

AMD has yet to publicly release the R600 (Radeon HD 2000 / Radeon HD 3000) documentation, but the xf86-video-radeonhd developers at Novell have had this documentation under NDA. This documentation, however, is expected to be cleared for release soon.
