[mlir]the ptx compilation flow

[CONGCONGLEEE]

Recently I'm trying to run the model compiled by onnx-mlir on GPU.
Here is my idea about the compilation flow:
affine/scf/std Dialect -> gpu Dialect ->NVVM IR -> LLVM IR -> ptx assemble.
I have no idea whether it will work. If not, could you please share me some of your points? It would be very nice to get some help with this since I am not familiar with this area myself, thanks!

I think this is a good question for https://discourse.llvm.org/c/mlir/31 (I have not been working on GPU compilation recently).

The lowering path you propose sounds similar to what we have done in the open earth compiler but their have been a lot of changes since then. Having a look at something like IREE (https://github.com/google/iree) that AFAIK has an end-to-end GPU compilation workflow could help as well.

Ok, thank you very much!
