An Open-Source Radeon HD 4670? Sort Of.

When the Radeon HD 4850 and Radeon HD 4870 were introduced earlier this year, it was wonderful. These latest high-end graphics cards from ATI had same-day Linux support through their Catalyst driver and the open-source ATI drivers had "just worked" with the RV770 series. The mode-setting support with the xf86-video-ati and xf86-video-radeonhd drivers just required adding in the PCI IDs for these new PCI Express graphics cards and then the rest of the magic was provided by AtomBIOS. However, with the introduction of the Radeon HD 4600 series, not everything is working instantly with the open-source drivers.

ATI R500: Mesa vs. Catalyst Benchmarking

With Mesa 7.1 having been released this week and the open-source R600/770 3D support just around the corner, we've taken this opportunity to see how the open-source Mesa 3D stack compares to AMD's monthly-refined Catalyst Linux Suite with the fglrx driver performs for the Radeon X1000 (R500) series. In this article are Mesa 7.1 and Catalyst 8.8 benchmarks for the Radeon X1300PRO and X1800XL graphics cards.

NVIDIA 177.68 Beta Driver

Tuesday the NVIDIA 177.67 Display Driver was released and then yesterday the ATI Catalyst 8.8 Driver came out with OverDrive and CrossFire support. Today though we are back with another NVIDIA Linux driver release. Due to fallout from the 177.67 driver, NVIDIA has replaced it just two days later with the 177.68 Beta.

AMD OverDrive On Linux

When it comes to ATI hardware, one of the features we have been after for the longest time on Linux has been any overclocking support. Windows users have ATI's OverDrive at their disposal along with an arsenal of third-party utilities such as ATI Tool. NVIDIA also has various utilities for overclocking their graphics cards on Windows, but they also provide support for overclocking on Linux. Today though with the release of the Catalyst 8.8 Linux driver there is finally ATI OverDrive 5 support on Linux.

AMD Catalyst 8.8 Linux Driver

AMD had delivered same-day Linux support when launching the Radeon HD 4800 series this summer. This was a first for AMD when launching a major product revision that there was same-day support considering for the R500 and R600 (and earlier) generations it had taken months for any level of support on Linux. This was great to see and the Radeon HD 4850/4870 performance was terrific thanks to their new OpenGL driver introduced last September. Today AMD has announced another Catalyst driver release for Linux and this is arguably the most significant driver update since last October's release when AIGLX support was added. Catalyst 8.8 delivers CrossFire support on Linux, OverDrive overclocking support, adaptive anti-aliasing support, and other improvements.

NVIDIA 177.67 Display Driver

It has been a few weeks since NVIDIA last pushed out a Linux display driver update, but this morning already they have pushed out a new update. The just-released NVIDIA 177.67 display driver doesn't introduce OpenGL 3.0 support or any other major features, but it does look to resolve a number of bugs, provide improvements to the Render extension, add official support to the GeForce GTX 260/280 graphics cards, and a number of other improvements.

Coming Soon: AMD R600 3D Documentation

For months we have been telling you that AMD has been preparing to release their R600 series documentation as well as opening up the source-code to two of their internal software projects used for testing new graphics processor designs prior to the availability of the actual hardware. Advanced Micro Devices has yet to release their 3D programming documentation covering the R600 series (or the brand-new RV770) nor the source-code to their two internal projects (TCore and KGrids), but following several postings in our forums over the past couple of weeks and many emails inquiring about the status, today we have a brief update to share.

OpenGL 3.0, GLSL 1.30 Released

From SIGGRAPH 2008, one of the premiere computers graphics conferences, the Khronos Group has announced the release of the OpenGL 3.0 API specification and the GLSL 1.30 shading language specification. This is the first major update to this cross-platform 3D programming API since the OpenGL 2.1 release two years ago. In this article we have a bit of information on these OpenGL and GLSL updates and when we can expect to see the Linux graphics scene moving to this new standard.

NVIDIA 173.14.12 Linux Driver

Yesterday KDE 4.1 was released and there are widely known 2D performance problems with the GeForce 8 and 9 series, which are especially exhibited when using the K Desktop Environment. So you think NVIDIA would address this issue in their next driver update? Guess again. Early this morning NVIDIA had released a new driver as version 173.14.12. This is the first NVIDIA Linux driver release in a month and a half, but its change-log is quite slim.

AMD Releases New AtomBIOS Parser

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.
