examples/libblkio-virtio-blk-vfio-pci.fio

; Benchmark accessing a PCI virtio-blk device using libblkio.
;
; Replace "/sys/bus/pci/devices/0000:00:01.0" below with the path to your
; device's sysfs directory, or override it by passing the '--libblkio_path=...'
; flag to fio.
;
; In the example below, the two subjobs of "job-B" *and* the single subjob of
; "job-C" will share a single libblkio instance, and "job-A" will use a separate
; libblkio instance.
;
; For information on libblkio, see: https://gitlab.com/libblkio/libblkio
