The peer to peer (P2P) data transfer is important for programs that use multi-GPU. 

The heterogeneous memory management (HMM), is a mechanism to treat CPU memory
and GPU memory in a joint address space. It is an essential part of Unified
Memory in heterogeneous computing, which frees the developer from manually
handling data migration across different types of memories. Data will be
automatically transferred and cached into the memory of the compute node. This
programming model is gaining popularity, and for AMD GPU and ROCm, cards that
support xnack replay can utilize this model if CONFIG_HSA_AMD_SVM=y
