[PATCH 0/7] Xen transport for 9pfs frontend driver

From: Stefano Stabellini
Date: Mon Mar 06 2017 - 15:00:55 EST


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 frontend, which typically runs in
a regular unprivileged guest.

I'll follow up with another series that implements the backend in
userspace in QEMU, which typically runs in Dom0 (but could also run in
a another guest).

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

Stefano Stabellini (7):
xen: import new ring macros in ring.h
xen: introduce the header file for the Xen 9pfs transport protocol
xen/9pfs: introduce Xen 9pfs transport driver
xen/9pfs: connect to the backend
xen/9pfs: send requests to the backend
xen/9pfs: receive responses
xen/9pfs: build 9pfs Xen transport driver
