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.

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.

This afternoon at FOSDEM 2008 in the X,Org development room, Keith Whitwell of Tungsten Graphics had provided a status update on the Gallium3D graphics driver architecture followed by Jerome Glisse talking about his work in porting the Radeon driver from DRM to Gallium3D. Jerome had also commented on other Radeon/X.Org topics such as kernel mode-setting. In this article are Gallium3D notes from these two talks.

Starting off the X.Org talks at FOSDEM 2008 was AMD's John Bridgman, who has been leading the AMD GPG open-source efforts. John had talked briefly about the history of their open-source efforts for the R500+ series and the evolution of AMD GPU hardware. Among the interesting comments made were that TexturedVideo/X-Video support for the R500/600 may be coming quite soon, DRM and Mesa work forthcoming, open-source multi-GPU CrossFire support is on the road-map, and they will be re-releasing R200 programming documents. The RV620 and RV635 documentation is expected in the near future.

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.

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.

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 last September when AMD's new open-source strategy was unveiled, their xf86-video-radeonhd driver and NDA-free documentation efforts have largely been to improve its Linux customer base. However, with this open community enablement, it has also led to an improved ATI hardware status in Sun's Solaris Operating System. Introduced in Build 80 of OpenSolaris was the RadeonHD display driver and this R500/600 driver has now appeared in Solaris Express Developer Edition 1/08 and Project Indiana Preview 2.

Last night NVIDIA quietly uploaded a new Linux display driver to their FTP server. This new driver is tagged 171.05, while the latest public driver has been 169.09. Having already three releases in the 169.xx series, this is a moderate update to 171.xx, but according to NVIDIA it's not for everyone. There is no official
change-log that NVIDIA has published for the 171.05 driver, and the change-log that ships with the driver hasn't been updated (whether it be intentional or not). The only word that has come out of the NVIDIA camp on this new driver is from Christian Zander and he has said that this driver is only intended for use with the Tesla S870 GPU Computing Systems. The legacy NVIDIA Linux drivers have also been updated this week.

At the Linux.Conf.Au conference today, Intel has announced NDA-free programming documentation covering the 965 Express and G35 Express integrated graphics processors (IGPs). Intel's display driver has long been open-source, but up until now, they have not been releasing the programming documentation for these products to the public. This move comes months after AMD announced their new open-source strategy and began releasing register documentation on their R500 and R600 GPUs. These newly released documents by Intel even cover 3D and video programming for their IGPs.
