[Xen-devel] [PATCH v2 0/9] xen/9pfs: introduce the Xen 9pfs backend

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Hi all,

This patch series implements a new transport for 9pfs, aimed at Xen
systems.

The transport is based on a traditional Xen frontend and backend drivers
pair. This patch series implements the backend, which typically runs in
Dom0. I sent another series to implement the frontend in Linux
(http://marc.info/?l=linux-kernel&m=148883047125960&w=2).

The backend complies to the Xen transport for 9pfs specification
version 1, available here:

http://xenbits.xen.org/gitweb/?p=xen.git;a=blob_plain;f=docs/misc/9pfs.markdown;hb=HEAD


Changes in v2:
- fix coding style
- compile xen-9p-backend.c if CONFIG_XEN_BACKEND
- add patch to set CONFIG_XEN_BACKEND only for the right targets
- add review-bys

Stefano Stabellini (9):
      configure: change CONFIG_XEN_BACKEND to be a target property
      xen: import ring.h from xen
      xen: introduce the header file for the Xen 9pfs transport protocol
      xen/9pfs: introduce Xen 9pfs backend
      xen/9pfs: connect to the frontend
      xen/9pfs: receive requests from the frontend
      xen/9pfs: implement in/out_iov_from_pdu and vmarshal/vunmarshal
      xen/9pfs: send responses back to the frontend
      xen/9pfs: build and register Xen 9pfs backend
