In recent weeks we have published a number of benchmarks showcasing the ATI Gallium3D driver that supports the R300-R500 graphics processors as this open-source driver has been maturing at such an exciting rate with impressive changes and measurable performance gains over a short period of time. This ATI Gallium3D driver in most instances is outperforming the classic Radeon Mesa driver that supports up through the ATI Radeon X1000 series graphics cards. However, how is the Nouveau driver maturing that supports NVIDIA's wide-range of GeForce graphics cards? In February we published some Nouveau Gallium3D benchmarks, but now we have a fresh set of numbers from three different NVIDIA graphics cards and we also compare the Nouveau Gallium3D driver to NVIDIA's proprietary Linux driver.

In this month's AMD Catalyst 10.6 driver update for Linux they rolled out the ATI 2D Acceleration Architecture, which pleased many ATI Radeon customers, but they aren't the only ones working towards improved 2D support. Intel's open-source engineers have been working to optimize their xf86-video-intel DDX driver 2D performance with much of this work being clearly shown in the Intel 2.12 X.Org driver update. Here are some benchmarks showing the significant performance gains brought by this open-source Intel driver.

It has been two years since the ATI Radeon HD 4800 (RV770) series launched so we have gone back since that monumental hardware launch and have re-tested each Catalyst driver release since then to see how the performance has changed for the ATI Radeon HD 4850 graphics card. The Catalyst driver has certainly matured over the course of two years in speeding up the OpenGL performance with this hardware along with bringing new features to their proprietary driver, but it is not exactly smooth sailing.

Earlier this week AMD released the Catalyst 10.6 driver that on the Linux side of the table had finally made use by default of their new 2D acceleration architecture, offered official support for Red Hat Enterprise Linux 5.5, and formalized their OpenGL 3.3/4.0 support. Since the release of the Catalyst 10.6 Linux driver, we have been running a new set of tests on their new ATI 2D acceleration architecture, but the results are not what you may expect when compared to the open-source ATI Linux driver.

A number of weeks back a set of benchmarks were published showing even the latest open-source ATI 3D driver is still no match to an old Catalyst driver and that even Gallium3D lags behind the Catalyst driver for those interested in OpenGL gaming. However, in other areas the open-source ATI driver stack is beginning to win by measurable amounts.

Last week prior to heading over to Germany for LinuxTag, I had ran a new set of ATI R500 Gallium3D benchmarks with an ATI Radeon X1950PRO graphics card and comparing the latest Mesa/Gallium3D graphics driver performance in the Mesa 7.9-devel Git code with both the Gallium3D and classic Mesa DRI drivers to the older Mesa stack found in Ubuntu 10.04 LTS. The ATI "R300g" driver as its known continues to advance, and over the past week this driver has pushed forward even more. Here is another set of ATI Gallium3D tests.

There was a talk last week at LinuxTag in Berlin by Egbert Eich about kernel mode-setting and the DRM (Direct Rendering Manager) graphics stack on Linux. Egbert is, of course, a long-time X developer and openSUSE developer at Novell who was one of the masterminds behind the RadeonHD graphics driver and has worked on various pieces of X over the years. In Egbert's brief KMS talk he briefly covered the history of the Linux graphics stack, the user and kernel-space APIs for DRM mode-setting, and related topics. For those that missed out on his talk, below are his slides.

The past several months have been very exciting in the world of Gallium3D, the new graphics driver architecture for Linux and other operating systems that has been in development for years. This year we have witnessed the emergence of LLVMpipe to accelerate OpenGL commands on the CPU, Nouveau's Gallium3D driver starting to work well, and many other advancements. Over the past few months we have also been pleased with how the "R300g" driver has taken shape with this Gallium3D driver for ATI Radeon R300/400/500 series hardware (up through the Radeon X1000 series) stabilizing, performing well, and advancing beyond the classic Mesa 3D R300 driver. Today we have a fresh set of benchmarks looking at this ATI Gallium3D driver that soon will become the default.

Last week NVIDIA released their first 256.xx proprietary beta Linux display driver that brought many VDPAU improvements, installer improvements, support for new GLX extensions, various bug-fixes, and other enhancements. However, some user reports have shown the 256.xx driver is actually slower than NVIDIA's current pre-200.xx series drivers and so we have carried out a set of tests to see what things are looking like from within our labs. Our preliminary tests do indeed illustrate a drop in performance when upgrading to this new driver.

Yesterday we reported on VIA's Linux dreams not materializing with their GEM/TTM memory management support still missing even though we are half-way into 2010 -- more than two years after VIA announced its most recent open-source initiative. It turns out, however, for what VIA views as its memory management work is actually done. VIA has inconspicuously handed over some of its code to the OpenChrome developers in order to create a new driver that has been dubbed the "openvia" driver. VIA has supposedly provided the source-code to an X driver plus TTM/GEM DRM, but this new project largely remains a hidden mystery.
