We use CMake to determine if we're compiling against a version of ROCm that supports gcnArchName and handles architecture checking appropriately. It includes a few helper functions as drop ins for the functionality we used gcnArch for before; sometimes to enable flags, and sometimes to set frequencies.
[ROCm/rccl commit: e58ec78d35]
* initial checkin
* enable msccl when hip graph is on
* remove the commented out code of msccl enable check
* clean up the code
* remove the msccl HighestTransportType check logic
[ROCm/rccl commit: e1dc4d5e42]
Current number of transmissions parsed from MSCCL algorithm is 1-based value,
but when calculating proxy number of chunks, it's taken as 0-based value.
This commit fixes this issue.
[ROCm/rccl commit: f7dc7b7e6a]

[ROCm/rccl commit: ea38312273]
* add DMA_BUF support
* remove unused libraries in src/init.cc
* change NCCL_ALL to NCCL_INIT
* remove extra pointer functions in transport/net.cc
[ROCm/rccl commit: d52b6c0d24]
Added a RCCL_MSCCL_ENABLE_DONE_EVENT env var, set it be 0 by default.
The env var is to control whether to use doneEvent when invoking MSCCL
kernels.
Skipping doneEvent would cause the firmware to skip L2 cache flush,
resulting in overall performance improvement.

* Revert "Ensure memory copy integrity during transport setup (#731)"
This reverts commit 0c0c35927a.
Add stream synchronization in ncclStrongStreamRelease.
* Use event record and wait
