Implement a new virtio_9p device to be used for sharing directories with the VM. BUG=chromium:703939 TEST=mount inside a VM and run `bonnie++ -r 256` Append the shared directory to the crosvm command line: --shared-dir /path/to/dir:test_9p Then mount in the guest: mkdir /tmp/9p mount -t 9p -o trans=virtio test_9p /tmp/9p -oversion=9p2000.L Or for a 9p root: run --shared-dir /mnt/vm_root:/dev/root -p 'root=/dev/root ro rootflags=ro,trans=virtio,version=9p2000.L,cache=loose rootfstype=9p' vmlinux.bin CQ-DEPEND=CL:1065170 Change-Id: I41fc21306ab5fa318a271f172d7057b767b29f31 Signed-off-by: Chirantan Ekbote <chirantan@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/1065173 Commit-Ready: ChromeOS CL Exonerator Bot <chromiumos-cl-exonerator@appspot.gserviceaccount.com> Reviewed-by: Dylan Reid <dgreid@chromium.org>
