Mesa 26.1 now includes support for the Arm Ethos U85 NPU in the EthosU Gallium3D driver, enabling AI workloads via Mesa's TEFLON framework. Developer Tomeu Vizoso implemented the U85 support, which builds incrementally on the existing U65 cmdstream, introduces a new scheduler, and upgrades to a newer weight encoder in Vela. The Ethos U85 offers 20% better energy efficiency than the U55/U65, scales from 128 to 2048 MAC units, and targets edge AI use cases paired with Cortex-A and Cortex-M processors.
