@mergennachin can you take a look?

Is it intended to delete this file?

[neuropilot-captain]

Yes, we have to move this file to NP Express SDK because it is a MTK proprietary header

thanks @neuropilot-captain for the PR.

Three things:

• What about this file? https://github.com/pytorch/executorch/blob/main/examples/mediatek/executor_runner/mtk_llama_executor_runner.cpp
• If you were to delete backends/mediatek/runtime/include/api/NeuronAdapter.h altogether from this repo, what happens to all the existing references to this header? https://github.com/search?q=repo%3Apytorch%2Fexecutorch%20NeuronAdapter.h&type=code
• do you need to update any documentations on how to download the file from NeuroPilot Express SDK

Hi @mergennachin, thanks for reviewing this PR.

1. We have removed the license in the latest patch
2. 3. The users will have to copy the header to api directory from NeuroPilot Express SDK. We have updated the README for this. The header will be added to the SDK by this month

[mergennachin]

Okay, I will merge this PR, as this unblocks the license issue.

But consider a few options moving, as this hinders user adoption experience:

• Automatic script that does necessary stepping the SDK, including the copying .h file.
• Provide a very thin integration header .h file that has more permissible license, and contains only the public API definitions, without any proprietary stuff that can be in any open source repo. And still have a proprietary .h file in the SDK, that defines proprietary stuff.
