Virtual environments without PCI support (a common situation in embedded devices models) might use simple memory mapped device instead of the PCI device. The memory mapped Virtio device behavior is based on the PCI device specification. Therefore most operations including device initialization, queues configuration and buffer transfers are nearly identical. For more details and existing differences please see: http://docs.oasis-open.org/virtio/virtio/v1.0/cs04/virtio-v1.0-cs04.html#x1-1090002 BUG=b:189182339 TEST=boot manatee and verify that Virtio PCI devices work properly Change-Id: If7aeb03b96137a672438f85ba2b86296deeef9ca Reviewed-on: https://chromium-review.googlesource.com/c/crosvm/crosvm/+/3855006 Reviewed-by: Daniel Verkamp <dverkamp@chromium.org> Tested-by: Tomasz Nowicki <tnowicki@google.com> Commit-Queue: Tomasz Nowicki <tnowicki@google.com>
