Known Issues

1. The function_params field of cupti.cupti.CallbackData is currently not supported, None will be returned if used.

2. The cupti.cupti.CallbackDomain.NVTX domain is not supported, hence there is no way to get callbacks for NVTX APIs.

3. Libraries like NCCL that emit NVTX annotations with extended payloads can now be decoded using CUPTI; however, this capability is not yet supported in CUPTI Python.
