[ROCm/rccl commit: 6505639cf4]
* Limit P2P channels per peer to not exceeding max channels
* [UT] test single GPU cases for all collectives
* [UT] fix out of range root value
[ROCm/rccl commit: 4237caad69]
* misc/msccl: read graphCaptureStatus for every collective call
* fix a bug in checking whether UBR is enabled in MSCCLPP
* cmake: Fix patch reversal order
* misc/msccl: add logging
[ROCm/rccl commit: 23c0b7bd84]
* Improve RDMA flushing by write dummy payload with RO=0
* Rename env var for disabling this change to RCCL_GDR_FLUSH_GPU_MEM_NO_RELAXED_ORDERING
[ROCm/rccl commit: 60c1264d27]
* Enable GDRCopy only on gfx94x
* Use cudaFree instead of hipFree
* Add warning if failed to get device property
* Remove extra return
[ROCm/rccl commit: 32dc7ef47c]
* Print KL/CL/KE events for all warps
* Fix count off-by-one issue
* Fix opCount in KE and restore CPU thread option
* Simplify count calculation
[ROCm/rccl commit: ebf7e2305e]
* erase handle key from mscclpp communicator during deregistration
* remove check on buffer size being a multiple of 32 from registration/deregistration routines since these checks are applied during enqueue
* add check for greater than zero buffer size in mscclpp registration
[ROCm/rccl commit: 19105206f6]
* Fix collective trace
* Use nontemporal for st_global
* Fix previous commit
* Add HDP flush to data receive path
* Fix previous commit
* Control flushing by NCCL_NET_FORCE_FLUSH and RCCL_NET_HDP_FLUSH
* Introduce RCCL_NET_HDP_FLUSH and RCCL_NET_GDR_FLUSH
Both are on by default. Turn both off will skip all flush will likely
result in data error.
* Enable GDR copy by default
* Remove GDR flush env var because it is disabled by GDC flush
* Output kernel collective trace at comm destroy by default
* Limit kernel timeout messages to 100
* Use system relaxed atomic for loadInt
* Refine timeout messages and use atomic for setting offset from CPU
* Add kernel trace for barrier timeout
* Add backup barrier to avoid race in atomicAdd
* Use different counters for different warps
* Rework barrier implementation
* Fix for other GFX
* Use __hip_atomic_store and __hip_atomic_load
* Fix bug in previous commit
* Don't reset barrier values in running kernel
* Update trace format
* Fix typo
* Switch back to hip_atomic_fetch_add
* Use same barrier implementation for all GFX
* Remove extra threadfence
* Turn off HDP flush by default
Please use RCCL_NET_HDP_FLUSH=1 to switch on HDP flush
* Remove unnecessary changes from alterative barrier implementation
* Added back __threadfence_block
* Revert back to threadfence for gfx other than gfx94x
[ROCm/rccl commit: caba0bc049]
* Added RCCL env params to control setting the SO_REUSEADDR and SO_LINGER socket options. This can allow control over the number of file descriptors created during bootstrapping.
* Casted the linger value to `int` sooner to avoid a scope of unknown typed-ness.
* Added CHANGELOG entry for this feature.
[ROCm/rccl commit: 2e35417fe5]
* ext-src: add MSCCLPP memory registration APIs
* update mem-reg patch with mscclpp helper routine to check if buffer is registered
* RCCL integration of MSCCL++ user-buffer registration APIs
* only include mscclpp_nccl header if ENABLE_MSCCLPP is defined
* ext-src: update mscclpp mem-reg patch
* add helper routine to patch
* check handle before MSCCL++ deregister
* fix typo to replace send buff with recv buff
* in case of no mscclpp registration, dduring deRegister call, ont fall back to rccl deRegister which will return an error
* Apply suggestions from code review
Whitespace suggestions and reducing diffs to avoid future merge conflicts

* rename helper functions and change their return type
* set RCCL user-buffer registration to occur if attempting MSCCL++ registration with a buffer in managed memory

[ROCm/rccl commit: e9b6bbca8a]
It seems like here wants to check xgmi_node instead. If checks node for "nvlink", it will verify the link_info everytime.
If checks node for "xgmi", when get yes answer, it won't need check vsmi topo interface.
