The Linux driver stack for Arm(R) Ethos(TM)-U provides an example of how a rich operating system like Linux can dispatch inferences to an Arm Cortex(R)-M subsystem, consisting of an Arm Cortex-M of choice and an Arm Ethos-U NPU.
The driver stack comes with a CMake based build system. Cross compile for an Arm CPU can for example be done with the provided toolchain file.
$ mkdir build $ cd build $ cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchain/aarch64-linux-gnu.cmake -DKDIR=<Kernel directory> $ make
The kernel driver uses the mailbox APIs as a doorbell mechanism.
