One of the linux base support is here: GitHub - Xilinx/mlir-aie: An MLIR-based toolchain for AMD AI Engine-enabled devices.
look to have more simple sdk than the Vitis-aie support.
The linux driver is in place, now “we” need to work with this “sdk/compiler” to port software on the NPU (llama.cpp …)
(for now I play with vitis on a xilinx vek280 that have the same NPU (much bigger 304 compute tile vs 20 on Ryzen 7840) than the zen4 APU. But if diff on program CPU vs GPU is like change continent, CPU vs NPU is like change planet.)
