Support for cutting-edge hardware has often been inconsistent on Linux, but it seems that the new AMD Radeon RX 9070 and 9070 XT GPUs might be an exception, possibly due to their unusual release timing.
AMD’s Commitment to Linux
As reported by Phoronix, AMD’s RADV open-source Vulkan driver for Linux has already been updated to include support for the unreleased AMD RDNA 4 GPUs. This information was shared by Samuel Ptoiset, who is the lead of Valve’s Linux graphic driver team. He assured that the support for RDNA 4 at launch would be “good enough.”
Ptoiset mentioned, “This initial support should be good enough but it’s missing two features (cooperative matrix and video decode/encode) compared to GFX11 (RDNA3) because lack of time.”
Ongoing Developments
While there are still some features missing, such as Delta Colour Compression and Vulkan Video support, work is actively ongoing to address these gaps. Ptoiset expressed optimism that these final details could be completed ahead of the RDNA 4 launch in March. He stated, “DCC is still under active development, but it might be possible to finish it during the RC period.”
Even if these features are not ready by the time the Radeon RX 9070 and 9070 XT GPUs are released, they are still expected to be functional. This is a more favorable situation compared to what often occurs with new hardware. After the launch, efforts will likely focus on enhancing support and performance for specific features, while also fixing any bugs that may arise.
Upcoming Driver Updates
The new RADV open-source driver will be included in the Mesa 25.0 update, which is anticipated to be available by the end of February, aligning perfectly with the release of the Radeon 9070 series GPUs. These updates will probably require a relatively recent kernel version, and Phoronix estimates that the minimum requirement will be Linux 6.13 or 6.14.
