> This series is adding minimal support to use 9pfs in Mini-OS. It is
> adding a PV 9pfs frontend and the ability to open, close, read and
> write files.
>
> The series has been tested with qemu as 9pfs backend in a PVH Mini-OS
> guest (I've used a slightly modified Xenstore-stubdom for that purpose
> in order to reuse the build runes).
>
> This series is meant to setup the stage for adding file based logging
> support to Xenstore-stubdom and later to add live update support (being
> able to save the LU data stream in a dom0 file makes this a _lot_
> easier).

> In order to keep Mini-OS's license I have only used the protocol docs

> backend implementation (especially for supporting the 9P2000.u variant,
> as qemu doesn't support the basic 9P2000 protocol).
>
> The needed fixed values of the protocol have been taken from [2].
