In addition to [1]many RadeonSI driver optimizations that were merged just prior to yesterday's [2]code branching and Mesa 24.1-rc1 release , a number of Etnaviv driver improvements were also merged for benefiting that recent Vivante NPU IP open-source driver work.

Merged earlier this cycle for Mesa 24.1 is [3]Teflon as a Gallium3D front-end for TensorFlow Lite and initially used by Etnaviv, the reverse-engineered Vivante graphics driver. The Etnaviv NPU driver support has come together nicely and for some inferencing workloads [4]can be nearly as fast as the proprietary driver .

Tomeu Vizoso who has been leading this NPU effort landed " [5]bunch of fixes and optimizations " that he's been accumulating for the Etnaviv driver.

Among the optimizations are [6]enabling an image cache using the on-chip SRAM that is helping reduce times such as MobileNetV1 dropping from 9.9 ms to 6.2 ms or SSDLite MobileDet from 27 ms to 24.3 ms. Plus a few other Etnaviv improvements as a nice end to the Mesa 24.1 feature work.
