[Question] Inquiry Regarding Android CPU & Vulkan Support in MLC-LLM

[FilipFan]

Hi,

I'm new to mlc-llm and have been exploring its support for the Android platform.

From the README.md and my review of auto_target.py, it appears that OpenCL is the primary supported backend for Android. I'd like to confirm my understanding and ask a few follow-up questions:

• Is the CPU backend currently unsupported for Android?
• Is the Vulkan backend also unsupported at this time?

If the above is correct, I'm curious about the implementation path:

• Given Android's strong native support for Vulkan, I was wondering what the considerations are for not supporting it yet?
• If there are technical limitations, do they stem from dependencies in TVM or from the MLC-LLM implementation itself?

Thanks for your time and any insights you can provide!
