block: Add VFIO based NVMe driver
This is a new protocol driver that exclusively opens a host NVMe controller through VFIO. It achieves better latency than linux-aio by completely bypassing host kernel vfs/block layer. $rw-$bs-$iodepth linux-aio nvme:// ---------------------------------------- randread-4k-1 10.5k 21.6k randread-512k-1 745 1591 randwrite-4k-1 30.7k 37.0k randwrite-512k-1 1945 1980 (unit: IOPS) The driver also integrates with the polling mechanism of iothread.
