Over the past year, Timur Kristóf of Valve's Linux graphics driver team has made multiple improvements to the AMDGPU kernel driver for enhancing support for old GCN 1.0/1.1 era graphics cards. This week in Toronto, Kristóf presented on this work that he initially began as a kernel driver development exercise after years spent in user-space focused on the Mesa 3D driver code. Timur Kristóf has become a legend for those with old AMD GCN 1.0/1.1 graphics cards and APUs for transitioning them from the legacy Radeon driver over to the modern AMDGPU kernel driver, which unlocks being able to use the RADV Vulkan driver, better performance, and all-around better functionality than the legacy Radeon code.
In the process he had to address defects in the AMDGPU display code for these legacy graphics cards along with various power management issues. Then he went on to improve these graphics cards further with soft reset support and other enhancements all to make these aging graphics cards more viable for Linux gaming use in 2026 and beyond. With AMD not devoting much resources to these aging graphics card driver improvements in years, Timur on Valve's Linux team really picked up the slack to make for a much better experience.
For those wishing to hear him recount his efforts for improving AMD Radeon GCN 1.0/1.1 era graphics on Linux, his XDC2026 presentation and PDF slides are embedded below.
