Reverse-Engineered Rockchip NPU Driver Hitting Same Performance As Proprietary Driver

To much surprise, just weeks after beginning his latest reverse-engineered driver adventure, his open-source code is already up and running the MobileNetV1 model on the Rockchip NPU. Most exciting is this statement:
"And it not only runs flawlessly, but at the same performance level as the blob."
He's been enjoying rapid success thanks to at least having some documented register information from Rockchip and their driver design being similar to NVIDIA's NVDLA and ONNX to which he can leverage documentation and code to help in the reverse engineering.
This Rockchip open-source driver work also relies on the Teflon framework that was upstreamed into Mesa as part of the Vivante/Etnaviv NPU driver effort.
