[Installation] Migrating TVM 3rdparty from Customized Fork to Upstream Repository

[LeiWang1999]

Hi @LeiWang1999 , I've compiled it with my own TVM, I used CUDA12 and LLVM14 with TVM v0.17.0,

However I can't find the path tilelang/python to set up the PYTHONPATH. I tried to use $PYTHONPATH=/home/chendi/hdd/git/tilelang/tilelang, but still got:

(tilelang) chendi@Workspace:~/hdd/git/tilelang$ echo $PYTHONPATH
/home/chendi/hdd/git/tilelang/tilelang
(tilelang) chendi@Workspace:~/hdd/git/tilelang$ echo $TVM_IMPORT_PYTHON_PATH
/home/chendi/git/tvm/python
(tilelang) chendi@Workspace:~/hdd/git/tilelang$ python -c "import tilelang; print(tilelang.__version__)"  
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/chendi/hdd/git/tilelang/tilelang/__init__.py", line 106, in <module>
    _LIB, _LIB_PATH = _load_tile_lang_lib()

    self._handle = _dlopen(self._name, mode)

though we consider tvm as a 3rdparty and utilize tvm via cmake include dependency, but the installation with upstream tvm is not fully tested yet.

pending due to the lack of a comprehensive Test #6

[LeiWang1999]

Must introduce tvm::runtime::kTVMGridConstant and HANDLE_TO_REFERENCE function to upstream tvm.

[LeiWang1999]

Likely upstream tvm also supports tma without these modifications, see pull request: apache/tvm#15684

I think we should learn and absorb their design.

closed, as tvm currently doesn't support tma desc init, which should hack tvm core.
