Over the past year, Timur Kristóf of Valve's Linux graphics driver team has made significant improvements to the AMDGPU kernel driver for old AMD GCN 1.0/1.1 era graphics cards. These enhancements, presented at XDC2026 in Toronto, aim to better support Linux gaming and other tasks on decade-old hardware. Kristóf transitioned these legacy cards from the old Radeon driver to the modern AMDGPU driver, unlocking the RADV Vulkan driver, improving performance, and resolving display and power management issues.
His work includes soft reset support and other optimizations to make aging GPUs viable for Linux gaming in 2026 and beyond. With AMD focusing less on these older drivers, Kristóf's efforts have provided a substantial performance boost, as seen in Linux 6.19's ~30% improvement for old AMD Radeon GPUs. His presentation and slides are available for those interested in AMDGPU kernel driver development.
