[win-pv-devel] [PATCH 00/14 v2] Support multiple consoles

[<owen.smith@xxxxxxxxxx>]

From: Owen Smith <owen.smith@xxxxxxxxxx>

Converts the xencons Fdo into a bus driver that enumerates 1 or more
Pdos. The first Pdo manages the static "default" console exposed by
the XENBUS_CONSOLE interface. Subsiquent Pdos manage the dynamic
non-default consoles that can be added to a VM. All consoles expose
several properties to differentiate their useage ("name", "instance",
and "protocol"). The monitor service is modified to manage multiple
consoles and create a named pipe for each, with the pipe's name being
based on the "name" property of the console (i.e. \\.\pipe\xencons\<name>)
Users of a particular console can directly connect to the well-known
name of the correct named pipe.

Currently, the default console (\\.\pipe\xencons\default) is used by
xencons_tty to expose a command line interface to the backend.
Additional uses should be defined in accordance with
https://xenbits.xen.org/docs/unstable/man/xen-pv-channel.7.html

Owen Smith (14):
  chmod 777 msbuild.bat
  Move console handlers to console.c
  Add boilerplate Pdo
  Move console handler to static Pdo
  Add IOCTLs to query instance, name and protocol
  Make monitor service multi-console aware
  Enumerate non-default consoles
  Hide console access behind an interface
  Add boilerplate frontend
  Respond to non-default console IOCTLs
  Add EVTCHN and GNTTAB interfaces
  Implement ring protocol
  Ensure D0 <-> D3 transitions occur from the correct state only.
  Fail FrontendPrepare if backend doesn't reinitialize
