When running networks of multiple machines, Simics assigns different disk IDs
to each disk created.
this change the boot priority and can't boot from SATA HDD directly.
Clear boot priority in NVRAM can fix this issue.

XenStoreWaitForEvent is going to be called when the ExitBootServices
is signaled, but both CreateEvent and WaitForEvent can't be used.
CreateEvent allocate some memory and WaitForEvent can only be used
when TPL is TPL_APPLICATION.
When ExitBootServices has been called, simply return immediately

This patch fix the EVT_SIGNAL_EXIT_BOOT_SERVICES handler to avoid
using the Memory Allocation Services.
This comes with a new interface named RegisterExitCallback so that PV
drivers can disconnect from the backend before XenBusDxe is teared
down.
Instead of using Disconnect() to tear down the
In order to be able to reset the backend before handing it to the next
operating system, it should be reset properly. This patch register a
callback function to be called by XenBusDxe during the
ExitBootServices event.

This patch rework the reception of xenstore watch event to avoid
allocation.
Instead of queuing watch events, we simply mark a XENSTORE_WATCH as
"triggered". We don't need to know how many time we received the
event, only that it happened. That avoid to allocate a
XENSTORE_MESSAGE for every watch
This patch rework XenStoreProcessMessage in order to avoid memory
allocation when a reply is expected. Instead of allocating a buffer
for this reply, we are going to copy to a buffer passed by the caller.
For messages that aren't fully received, they will be stored in a
buffer that have been
XsRead and XsBackendRead of the XENBUS_PROTOCOL return allocated
memory but this isn't allowed during the ExitBootServices call. We
need XsRead and XsBackendRead to disconnect from the device so
XENBUS_PROTOCOL is changed to use a buffer supplied by a child driver.

Hi,

We will use a buffer on the stack instead of allocating memory for

The external interface XENBUS_PROTOCOL isn't changed yet, so

Hi, Siva
The 10ms interval was chosen just by experience. This background polling
intends to pick up the coming request (e.g. ARP request) when there is no
active polling from upper layer. The ARP time out is 1 second, so using 10ms
background polling make the network stack able to receive ARP
The StandaloneMmPkg .DSC file went out of sync with the changes
applied to the package when I enabled this code on the Synquacer
platform in edk2-platforms. So apply the necessary changes to make
this package build in isolation.

MinPlatform PKG now use gEfiSmmSmramMemoryGuid instead of
gEfiSmmPeiSmramMemoryReserveGuid
to build memory HOB. SimicsOpenBoardPkg need to update for it accordingly.

These tests require using the "edk2-pytool" stuff but are easy to integrate
with the github PR or CI flow. Example of it running the code compliance tests
is here:

A test run takes about 3 minutes.

This change makes the following updates:
1. Add SimicsOpenBoardPkg details.
2. Update Python instructions to Python 3.x and mention
Python 2.x deprecation.
3. Add Linux build environment set up instructions.
4. Update supported compiler and tool versions to newer versions tested.

because split lock inside CpuExceptionHandlerLib.
