Linux Community Revives 20-Year-Old ATI Radeon Cards with New OpenGL Extensions

New OpenGL extensions for two decades old ATI-Radeon graphics cards show how far community support can go. Developers thus implement fresh memory management functions for R300 GPUs under Linux.

Community brings new features for veteran hardware

Nowadays it is normal that devices do not have to be sent to retire due to physical defects, but only because of the fact that software support is set by the manufacturer. The latest examples of this include the Gigaset Smart Home devices, Spotifys Auto accessories Car Thing or Microsoft’s sinfully expensive Surface hubs. In some cases, however, there are online communities that take care of the further supply of the hardware with updates.

The release of new Linux drivers for 20-year-old ATI-Radeon graphics cards now shows how far such community support can go. The independent developer Brais Solla has implemented two important OpenGL extensions for the R300 series, which originally started with the legendary Radeon 9700 Pro in August 2002.

The new extensions enable OpenGL programs such as GLXInfo to access detailed information about the available graphics memory. This is particularly relevant for the elderly cards, since they often only have 128 MB GDR memory. With this amount, every megabyte finally counts. As Phoronix reported, the official Windows support for this GPUS ended in March 2009 with the Catalyst 9.3 driver. It is all the more remarkable that the Linux community continues to supply the hardware with new features.

The R300 series

The R300 series marked the debut of the first completely DirectX 9-compatible consumer graphics chips and meant a turning point in GPU history. The Radeon 9700 Pro was introduced on August 19, 2002 and brought DirectX 9.0 support and OpenGL 2.0 to the desktop. With her 0.15-micrometer production technology and eight pixel pipelines, she set new standards for graphic performance.

For the first time, consumer graphics cards were able to perform complex shader programs that were previously reserved for professional workstation cards. With 110 million transistors and a 256-bit storage bus, the Radeon 9700 Pro had specifications that were impressive at the time. The card cost around 460 euros in its market launch and competed directly with Nvidia’s GeForce4-Ti series.

Technical details and availability

The current expansion provides detailed insights into VRAM consumption and similar functions for GPU hardware memory management. Both extensions help games and applications to manage storage use more efficiently. These extensions originally come from 2009, but were never implemented for the R300 architecture.

The implementation takes place as part of the upcoming MESA 25.3 version and will also support the following X700/X800 (R400) and X1000 (R500) series. Mesa 25.3 is currently under development and is likely to be released in the fourth quarter of 2025. The changes will also flow into the kernel space radeon drm driver, which continues to work with these 20-year-old graphics cards.
