ATI X.Org, Mesa Performance In Ubuntu

Late last month we published system benchmarks of Ubuntu 7.04 through 8.10 and had found -- at least with the Intel notebook we were using -- that the performance had degraded with time. This article had then resulted in benchmarks of Fedora 7 through 10 and most recently were Mac OS X 10.5 vs. Ubuntu 8.10 benchmarks. In our original article we hadn't focused much upon the graphics tests and we were just using ATI's binary driver, but per a request from Canonical's Bryce Harrington, we have carried out some open-source graphics tests on Ubuntu 7.04 through 8.10 and we started with the ATI performance.

Nouveau Companion 40

It's been almost six months since the last issue of the Nouveau Companion, but Pekka Paalanen has rejuvenated these efforts and has put out the 40th issue of this newsletter that updates the open-source community on the status of the Nouveau project, an effort to reverse-engineer NVIDIA's binary driver and provide a fully open-source 2D and 3D implementation. While we have been without the Nouveau Companion for many months, progress on the open-source Nouveau driver has continued. There is now GeForce 8 support with 2D EXA acceleration, work underway in implementing Gallium3D, switching the driver's memory manager from TTM to using a GEM API with TTM internals (similar to the ATI driver), and of course kernel mode-setting.

AMD's X-Video Bitstream Acceleration

In early September we shared that UVD2 and XvMC is coming to Linux and that two new library files had begun shipping with the ATI Catalyst driver: AMDXvBA and XvBAW. Earlier this month the Unified Video Decoding 2 (UVD2) support was then enabled by default in the Catalyst 8.10 driver. These video acceleration improvements to the ATI Linux driver aren't exactly end-user friendly yet, but today we have information on how those interested can begin using the X-Video Motion Compensation extension with their ATI hardware along with what the XvBA extension will provide users in regards to advanced video acceleration that is very similar to Microsoft's DirectX Video Acceleration.

NVIDIA Delivers Beta OpenGL 3.0 Linux Driver

The OpenGL 3.0 and GLSL 1.30 specification were released back in August during SIGGRAPH 2008. Just days later NVIDIA had delivered a beta driver for Windows that added OpenGL 3.0 functionality, but Linux, FreeBSD, and Solaris users were left in the dark. Two months later though NVIDIA has now published a beta Linux driver that implements most of the latest GL/GLSL specification.

Radeon HD 4550 Not Yet Open-Source Friendly

Last month we had looked at the ATI Radeon HD 4670 under Linux. This graphics card had worked just fine with the Catalyst Linux Suite, but when using either of the two open-source ATI drivers there were problems with the DVI connectors. While using an analog VGA connector works if you are just after mode-setting support, the R600/700 GPUs still lack 2D, 3D, and video acceleration using any non-Catalyst driver. Sapphire Technology though has sent out an ATI Radeon HD 4550 512MB GPU to see whether this sub-$50 USD graphics card plays nicely with the xf86-video-ati or xf86-video-radeonhd drivers.

Canonical Publishes ATI Catalyst 8.10 Beta

X Server 1.5 was officially released last month with X.Org 7.4, but there had been server pre-releases going back to earlier this year. Fedora 9 had even shipped with an early version version of X Server 1.5. For those using the open-source X.Org drivers, running the latest server is not a big deal, but those with ATI or NVIDIA binary drivers they sometimes can be slow in supporting the latest version. NVIDIA has supported X Server 1.5 for a number of weeks now, but ATI has yet to update their Catalyst Linux driver with such support. With Ubuntu 8.10 being released in two weeks and it's using this newest X Server, how will ATI graphics cards be supported? Well, an interesting event has occurred and we will tell you what has happened in this article.

RadeonHD 1.2.2 & 1.2.3 Drivers Released

The last release of the xf86-video-radeonhd driver was version 1.2.1 and that happened back in April. Since then we have seen a plethora of new work go into this open-source ATI driver for the Radeon R500 series and later. We've seen the driver add support for AMD's 780G Chipset and most notably it has adopted AtomBIOS to be used on the Radeon HD 4800 series and newer. There have also been numerous other improvements to this driver that currently competes with the xf86-video-ati driver. With much of this work now being settled, the Novell development team has released the RadeonHD 1.2.2 driver. In addition, they pushed out the RadeonHD 1.2.3 driver just moments later, which introduces their Command Submission infrastructure.

AMD's MultiView On Linux

Introduced in the Catalyst 8.8 Linux driver and further stabilized within Catalyst 8.9 was AMD's MultiView technology. MultiView makes it possible to use multiple GPUs on the same system not for Linux CrossFire but for driving multiple display heads. Using MultiView on Linux you can easily drive four, six, or even eight screens. In fact, up to 32 displays are theoretically supported on a single system (permitting you have enough graphics cards and PCI Express slots). MultiView also allows for OpenGL acceleration across all displays and does not rely upon Xinerama. In this article we are taking a brief look at this multi-GPU multi-monitor feature catered towards AMD's workstation customers.

NVIDIA 177.80 Display Driver

Over the course of the past few months we have seen several NVIDIA Linux drivers that have all been marked as beta with the last official release appearing in April. Today though NVIDIA has released the 177.80 Linux driver, which is an official update and christens the changes made with the 177.67, 177.68, 170.70, 177.76, and 177.78 beta drivers. Among the changes are RENDER extension improvements, finally officially supporting the GeForce GTX series, text rendering fixes, and there are 25 official changes in total.

The State of Kernel Mode-Setting

Earlier this year Fedora 9 was the first distribution providing kernel-based mode-setting (or KMS for short). At the time there was only a kernel mode-setting driver for Intel hardware and it ended up being disabled by default. We had provided a preview of kernel-based mode-setting that showed how the system display looked when it came to the flicker-free boot experience, fast and clean VT switching, and the technical advantages this method provides over the graphics mode-setting within an X.Org DDX driver. With months having passed since our first article and Red Hat engineers working aggressively on KMS improvements for Fedora 10, we are providing another look at this technology and some of the recent advancements.
