Last month right before FOSDEM 2008, the 3D programming documentation for the R500 GPUs (Radeon X1000) series was released. This documentation consisted of a register reference guide for the R500 GPUs as well as a programming guide covering such areas as the command processor, vertex shaders, and fragment shaders. While the register reference guide for the R600 series is still being worked on, for those with older ATI graphics processors, AMD has went back and created a register reference guide for the R300 series.

Following a period of relative inactivity in the xf86-video-radeonhd git tree over the past few weeks, this afternoon Novell's Egbert Eich had pushed forward 55 changes to this open-source R500/600 driver. The AMD Radeon HD 3400 and 3600 series are now supported and there are a number of other significant changes. The RV620/635 mode-setting support has required the most significant work since the R500 series, since all output blocks have been altered due to the introduced DisplayPort capabilities. We have already tested out this latest code and were left with a positive impression.

Last month we had measured Ubuntu's boot performance via the open-source Bootchart utility and had done this on all Ubuntu releases between Ubuntu 6.06 LTS and the latest development build at the time for Ubuntu 8.04 LTS. From this testing we had found the boot time to decrease with each official release and the maximum disk throughput increasing. With Fedora 9 Sulphur due out next month, we have done this same boot performance testing on the Fedora side with Core 4, Core 5, Core 6, 7, 8, and 9 Rawhide.

When the Intel Quad-Core "Clovertown" Xeon processors were introduced in late 2006 we had reviewed (among other motherboards) the Tyan Tempest i5000XT (S2696) motherboard. We had found this i5000X-based motherboard to work incredibly well with Linux and it ended up being awarded with our Editor's Choice Award for its impressive feature-set, Linux compatibility, and top-notch performance. It has been a while since last looking at a Tyan motherboard, but with the emergence of Intel's Wolfdale and Harpertown processors requiring new motherboards, today we are looking at the Tempest i5400XT S5396 motherboard. The Tempest i5400XT is similar to the i5000XT, but it's been upgraded to the new Intel 5400 MCH.

On the same day as the limited open-source support arriving in the xf86-video-nv driver, NVIDIA's binary display driver for Linux has been updated to officially add support for the GeForce 9600GT graphics card. This new driver update is version 171.06 (Beta) and its only change is the added 9600GT support, but that's compared to the 171.05 driver that was targeted specifically for the Tesla S870.

Earlier this week we previewed the Quadro FX1700, which is one of NVIDIA's mid-range workstation graphics cards that is based upon the G84GL core that in turn is derived from the consumer-class GeForce 8600 series. This PCI Express graphics card offers 512MB of video memory with two dual-link DVI connections and support for OpenGL 2.1 while maintaining a maximum power consumption of just 42 Watts. As we mentioned in the preview article, we would be looking at this graphics card's performance not only under Linux but also testing this workstation solution in both Microsoft Windows and Sun's Solaris. In this article today, we are doing just that as we test the NVIDIA Quadro FX1700 512MB with each of these operating systems and their respective binary display drivers.

Intel's Open-Source Technology Center is involved with a number of open-source Linux projects such as Threading Building Blocks, Moblin, PowerTOP, and the X.Org graphics driver. Intel also has vested interests in numerous other projects such as Xen and KVM. One of Intel's lesser-known projects, however, is the Linux-ready Firmware Developer Kit. The Linux-ready Firmware Developer Kit is a bootable CD that analyzes the BIOS or EFI on the test system to see how well it's able to work with Linux and what features are supported via the firmware. The primary purpose of this kit is for use by firmware developers, but it's also able to aide end-users in determining what BIOS features on their system will work with Linux.

Workstation GPUs are not our main focus at Phoronix, but with the increasing use of Linux on workstation systems, we will be starting to look at professional graphics products this month and likely more of them in the future. We are beginning this expedition by looking at the Quadro FX1700, which is one of NVIDIA's mid-range workstation graphics cards. This Quadro graphics card boasts 512MB of video memory, support for CUDA, and OpenGL 2.1 support. According to NVIDIA's product literature, the Quadro FX1700 is engineered to deliver exceptional performance, quality, and price for professionals.

It was a year ago that AMD had replaced its aging FireGL Control Panel inside its Linux driver with the AMDCCCLE, or AMD Catalyst Control Center Linux Edition. Since that time, this Catalyst Control Center for Linux continues to mature with a few new features being added here and there, and version 2.0 could in fact be introduced in an upcoming release. At the same time, the control panel utility that ships with NVIDIA's binary driver, nvidia-settings, has stayed more or less the same for the past few years with only a few minor revisions. How do these two Linux control panels compare though when it comes to the features? For this article we have put AMDCCCLE and nvidia-settings side-by-side to compare and contrast both utilities.

Since the release of Nexuiz 1.0 in 2005, we have been tracking its progress as one of the leading open-source first person shooters. With time, this fast-pace game has picked up a nice level of artificial intelligence for its in-game bots, engine optimizations, single-player campaign missions, and a variety of technical advancements. Nexuiz has always been one of the leading open-source first person shooter games, and with the release of Nexuiz 2.4 yesterday it reaffirms that you don't need to be a major game studio -- or a game studio at all -- to develop a quality title and even for being a free software game it has impressive graphics. With the graphical settings near maximized, a GeForce 8600GT on a quad-core system was brought to its knees by this free software (and free content) game.

Last week when traveling to Europe for FOSDEM and other business meetings, I had picked up a new 9-cell battery for a Lenovo ThinkPad T60. While an additional three battery cells will noticeably extend your battery life, you can also extend your battery life by taking a few simple steps to optimize your Linux desktop that will also reduce your power consumption and heat output. In this article are a few simple steps to take in order to extend your notebook's battery life on Ubuntu.

We know NVIDIA has been working on a new Linux display driver release, with the GeForce 9 series having been introduced just this past week, and today a new driver release has arrived for Linux, Solaris, and FreeBSD. However, this new 169.12 display driver doesn't introduce support for the GeForce 9600GT and its official changes are limited to maintenance items.

For the past several weeks we have been referencing AMD's "tcore" in several of our articles, which is a user-space software suite that has been developed and used internally at ATI by engineers to work on various aspects of their binary drivers. Tcore is primarily used for testing prior to the availability of the actual silicon for their forthcoming graphics processors. John Bridgman and Alex Deucher have been working tediously to get this tcore source-code sanitized and cleared for public release, and finally they have reached this milestone. AMD has just published the first bits of open-source 3D programming documentation for ATI GPUs. This 3D programming documentation covers the R500 series and even goes back with information on the R300/400 series as well. The R600 3D programming guide will also be out soon. This information available today is what will foster the growth of open-source R500/600 3D support for the Radeon and RadeonHD drivers as well as R600 2D acceleration.

Last December we had published benchmarks of seven versions of WINE, which covered up through the WINE 0.9.50 release. We had used two versions of Futuremark's 3DMark suite for testing, and with that we had found the performance to be stable in some cases while in later WINE releases we had found some performance losses. With the WINE project on a consistent two-week release cycle, we are looking at the WINE 3D performance and this time going back with the past eleven releases.

While Intel's X48 Express Chipset is not due out until the middle of March -- after having faced a few delays reaching production -- the kind folks at Gigabyte have today provided us with the Gigabyte X48T-DQ6 motherboard. This motherboard is similar to the Gigabyte X38-DQ6 that we reviewed last October, but it employs the new X48 Express MCH and the revised feature-set that this chipset brings to the hands of enthusiasts. This is our first Intel X48 motherboard review and the world's first look at this new flagship chipset under Linux. In this review of the Gigabyte X48T-DQ6 we will be comparing it to Intel's current P35 and X38 motherboards.

In the 35th edition of the Nouveau Companion, these open-source 3D NVIDIA driver developers talk about being a better bug reporter, X-Video improvements, PowerPC fixes, and MMioTrace being delayed until the Linux 2.6.26 kernel. At least three Nouveau developers will be at FOSDEM 2008 next week in Brussels, Belgium.

Last year leading up to the release of Ubuntu 7.04 "Feisty Fawn" and Ubuntu 7.10 "Gutsy Gibbon" we had published several articles looking at various aspects of this desktop Linux distribution. These articles had varied from looking at Ubuntu's power consumption for the past six major releases to presenting the visual history of Ubuntu and how its graphics have evolved since Ubuntu 4.10. With Ubuntu 8.04 "Hardy Heron" shipping in just two months, we are once again looking at Ubuntu from several points of view. In this article, we are looking at Ubuntu's boot performance for the past five releases through the use of Bootchart for measuring its boot time, disk throughput, and the running processes.

Whether it is a big or small update, every month AMD releases a new Catalyst package for both Linux and Windows for their supported ATI Radeon products. Last month in the Catalyst 8.01 Linux driver the changes had just consisted of a few bug fixes and nothing more. Today the Catalyst 8.02 Linux driver has been released, and like last month, it's short on the change-log. The fglrx changes are very brief and the driver version is still in the 8.45 release stream and wasn't even bumped to 8.46.x.

Since publishing our Linux review of the AMD Phenom 9500 on the Spider platform a month ago, we have continued in our investigation of this first AMD desktop quad-core processor that has been very problematic with Ubuntu 7.10 Linux. Fortunately though this support isn't stagnate and a better picture is painted when using the latest development builds of Ubuntu 8.04 "Hardy Heron" with the Linux 2.6.24 kernel. Per reader requests, we have carried out additional benchmarks of the Phenom 9500 to compare its 32-bit and 64-bit Linux performance.

On this Super Tuesday here in the United States, Red Hat has this morning released the first and only alpha release for Fedora 9. This ninth Fedora release, which has been codenamed Sulphur, will ship in April and go head-to-head against Ubuntu 8.04 LTS "Hardy Heron", but what features can one expect in this forthcoming release? Among the features being worked on are encrypted file-system support, updating the KDE spin to KDE 4.0, PackageKit integration, and switching to upstart initialization. In this article, we are taking a brief look at Fedora 9 Alpha and the features planned for Fedora 9.
