4 v9fs: Plan 9 Resource Sharing for Linux
10 v9fs is a Unix implementation of the Plan 9 9p remote filesystem protocol.
19 the 9p client is available in the form of a USENIX paper:

31 * PROSE I/O: Using 9p to enable Application Partitions

41 mount -t 9p 10.10.1.2 /mnt/9
43 For Plan 9 From User Space applications (http://swtch.com/plan9)::
45 mount -t 9p `namespace`/acme /mnt/9 -o trans=unix,uname=$USER
49 mount -t 9p -o trans=virtio <mount_tag> /mnt/9
52 mount points. Each 9P export is seen by the client as a virtio device with an
54 seen by reading /sys/bus/virtio/drivers/9pnet_virtio/virtio<n>/mount_tag files.
59 To mount a 9p FS on a USB Host accessible via the gadget at runtime::
61 mount -t 9p -o trans=usbg,aname=/path/to/fs <device> /mnt/9
63 To mount a 9p FS on a USB Host accessible via the gadget as root filesystem::
65 …root=<device> rootfstype=9p rootflags=trans=usbg,cache=loose,uname=root,access=0,dfltuid=0,dfltgid…
76 Diod (9pfs server) and the forwarder are on the development host, where
81 In this case the 9p requests come from the device and are handled by the
89 Just start the 9pfs capable network server like diod/nfs-ganesha e.g.::
91 $ diod -f -n -d 0 -S -l 0.0.0.0:9999 -e $PWD

104 $ python $kernel_dir/tools/usb/p9_fwd.py --path 2-1.1.2 connect -p 9999

176 0x04 display 9p trace
192 msize=n the number of bytes to use for 9p packet payload
196 noextend force legacy mode (no 9p2000.u or 9p2000.L semantics)
198 version=name Select 9P protocol version. Valid options are:
201 9p2000 Legacy mode (same as noextend)
202 9p2000.u Use 9P2000.u protocol
203 9p2000.L Use 9P2000.L protocol
210 afid security channel - used by Plan 9 authentication protocols
212 nodevmap do not map special files - represent them as normal files.
