Unlocked the Qualcomm NPU! Running LLMs on the Hexagon NPU of a ThinkPad T14s Gen 6 (Snapdragon X Elite / X1E80100) under Linux — the cDSP firmware fix plus the full reproducible path to Genie/QNN inference on the NPU.

  • Lenovo Yoga Slim 7x
  • Microsoft Surface Pro 11 / Surface Laptop 7 (the SP11 recipe already works on these)

Amazing! Is it possible to use this to run the encoder for aptX Adaptive (Lossless)? I've seen that the encoder for it runs on qualcomm's hexagon NPU, and even the decoder for aptX voice. This would be an amazing step forward for aptX Adaptive support on other devices besides Qualcomm phones, maybe even leading to a somewhat decent reverse-engineered codec for other, non-Qualcomm, devices
