The legacy mode means buffer sharing through KFD, KFD provide a buffer id to exporter, exporter pass it to importer, importer pass buffer id to KFD to query and import this buffer. The non-legcay mode relys on socket to pass dmabuf fd between processes. In hsa-runtime, the legcay mode is the default mode, setting environment variable HSA_ENABLE_IPC_MODE_LEGACY to 0 can force hsa-runtime to new mode code path.
