"SPDX-License-Identifier: MIT" (which refers to

that depend on it should use the same Xen interface version, so

This is the code that will do the actual communication between OVMF and
a PV block backend, where the block device lives. The protocol used is
describe in the blkif.h header.
This implementation originally comes from Mini-OS, a part of the Xen
Project.
Change in V4:
- add file header to BlockFront.h (license, copyright, brief desc)
Change in V3:
- Improve comment of XenBusReadUint64.
- Moving blkif.h to this patch
with the necessary #pragma pack(4) applied for Ia32.
- Add a note about the license in the commit message
- Add "The protocol used is describe in the blkif.h header." in the
commit message
- Have a mandatory sector-size multiple of 512 or fail to initialize.
- use Sector instead of Offset for IO request.
with Sector been 512-byte unit.
- print something if EventChannelNotify return an error.
Change in V2:
- trigger CoW is probably not needed on OVMF (as opposed to Mini-OS),
removed the test.
- comments
- renamed XenbusReadInteger to XenBusReadUint64
- remove callback from IoData, use simple status instead
- return a status from the synchronus io
- Close protocol if blockfront init fail.
- fix few debug print
- Rename XenbusIo to XenBusIo
- XenPvBlkWaitForBackendState will return an error if the new backend
states is not the expected state.
- Add the license

XenStore is a key/value database, which is running on another virtual
machine. It can be accessed through shared memory. This is a client
implementation.
Change in V3:
- moving xs_wire.h from patch #1 to this patch
- fix return value of XenStoreListDirectory
- Use a timeout to print a debug message if the other side of the
xenstore ring does not notify through the event channel.
This is done with the new XenStoreWaitForEvent function.
- Have XenStoreReadReply check status of XenStoreProcessMessage and
return an error if needed.
- Have XenStoreTalkv return the status of XenStoreReadReply.
- Have a loop to check for the quiescent of the response ring in the
XenStoreInitComms function. (with a timeout of 5 seconds)
- use the recently introduced XenStore 'closing' feature.
Change in V2:
- Change comment style, from freebsd to ovmf
- Fix type of EventChannel
- Fix debug print, no more cast
- Implement XenStoreDeinit.
- Clean up comments
- Fix few codding style issue
- Add FAIL xenstore status value.

This patch imports publics headers in order to use features from Xen
like XenStore, PV Block... There is only the necessary header files and
there are only a few modifications in order to facilitate future merge of
more recent header (that would be necessary to access new features).
There is little modification compared to the original files:
- Removed most of the unused part of the headers
- Use of ZeroMem() instead of memset()
- using #pragma pack(4) for IA32 compilation.
- Replace types to be more UEFI compliant using a script.
OVMF, when built for IA32 arch, uses the gcc switch -malign-double. This
change the alignment of fields in some struct compare to what is
espected by Xen and any backends. To fix the alignment, the #pragma pack(4)
directive is used around the struct that need it.
Command to run to change types:
find OvmfPkg/Include/IndustryStandard/Xen -type f -name '*.h' -exec sed
--regexp-extended --file=fix_type_in_xen_includes.sed --in-place {} \;
Avoid changing the 'long' that is not a type (with the first line).
$ cat fix_type_in_xen_includes.sed

Change in V4:
- Add a README in Xen headers directory to explain what have been done
to it. It is mostly a copy/past from the commit description with some
rewording.
- replace unsigned char by UINT8 as there is no unsigned char in UEFI
types.
Change in V3:
- Remove unused header sched.h
- moving xs_wire.h in a later patch, where it's first needed
- moving io/blkif.h in a later patch (XenPvBlkDxe: Add BlockFront client)
- moving event_channel.h in a later patch (XenBusDxe: Add Event Channel Notify)
- using #pragma pack(4) for IA32
- headers trimed down, removed most of the unused struct/define/...
