[Xen-devel] [PATCH RFC 00/18] Introducing Xen PV block driver to OVMF

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

Hi all,

This patch series is implementing the necessary in order to access a PV block
device. For that, one need a XenStore client, a XenBus client, and the PV block
driver.

There are two new drivers, XenbusDxe and XenPvBlkDxe. The first one implement a
bus drivers, and the second is a block drivers.

There are still a bit of work to be done on this series, especially the comment
in the code, but I'd like your comment on this patch series.

Anthony PERARD (18):
  OvmfPkg: Add public headers from Xen Project.
  OvmfPkg: Add basic skeleton for the Xenbus driver.
  OvmfPkg/XenbusDxe: Add device state struct and create an ExitBoot
    services event.
  OvmfPkg/XenbusDxe: Add support to make Xen Hypercalls.
  OvmfPkg/XenbusDxe: Open PciIo protocol.
  OvmfPkg: Introduce Xenbus Protocol.
  OvmfPkg/XenbusDxe: Add InterlockedCompareExchange16.
  OvmfPkg/XenbusDxe: Add Grant Table functions.
  OvmfPkg/XenbusDxe: Add Event Channel Notify.
  OvmfPkg/XenbusDxe: Add TestAndClearBit.
  OvmfPkg/XenbusDxe: Add XenStore client implementation
  OvmfPkg/XenbusDxe: Add an helper AsciiStrDup.
  OvmfPkg/XenbusDxe: Add Xenstore function into the Xenbus protocol
  OvmfPkg/XenbusDxe: Indroduce XenBus support itself.
  OvmfPkg/XenbusDxe: Add Event Channel into XenBus protocol.
  OvmfPkg/XenPvBlkDxe: Xen PV Block device, initial skeleton
  OvmfPkg/XenPvBlkDxe: Add BlockFront client.
  OvmfPkg/XenPvBlkDxe: Add BlockIo.
