Similar to virtio-scsi, which transports SCSI commands, virtio-fs transports FUSE requests and the protocol documentation is not duplicated here. The DAX window allows file contents to be accessed directly from shared memory. This eliminates copying of data, reduces the number of vmexits, and reduces the guest's memory footprint. It also allows coherent mmap MAP_SHARED semantics between guests on the same host.
