RADV open-source driver’s AMD RDNA4 support is now ‘good enough’

Radeon RX 9070 support added to Valve’s Linux GPU drivers

Patches say that support is ‘good enough’ but some features are still missing. 



It is not just AMD working on “optimizing drivers” for the Radeon RX 9070 launch. The company mentioned that this is the main reason it is taking more time to release the card, although no launch date was ever specified by AMD. Rumors suggested the new GPU was supposed to launch on January 23, just a week before the GeForce RTX 50 launch. However, and perhaps for the best, AMD decided to give itself another 1–2 months to build up stock and optimize software, avoiding mistakes similar to NVIDIA, whose RTX 50 cards are nowhere to be found.

Phoronix reports that optimizations are also underway for Linux GPU support. The open-source RADV drivers, maintained by Valve’s Linux graphics driver team, are currently in a good state, but at least two features are missing: cooperative matrix and video decode/encode. This note was shared by Samuel Pitoiset (Valve) along with the Mesa 25 update:
