MdePkg: use CpuPause() in CpuDeadLoop()
CpuPause() might allow the CPU to go into a lower power state
state while we spin.
On X86, CpuPause() executes a PAUSE instruction which the Intel
and AMD specs describe as follows:
Intel:
"PAUSE: An additional function of the PAUSE instruction is to reduce
the power consumed by a processor while executing a spin loop. A
processor can execute a spin-wait loop extremely quickly, causing the
processor to consume a lot of power while it waits for the resource it
is spinning on to become available. Inserting a pause instruction in a
spin-wait loop greatly reduces the processor?s power consumption."
AMD:
"PAUSE: Improves the performance of spin loops, by providing a hint to
the processor that the current code is in a spin loop. The processor
may use this to optimize power consumption while in the spin loop.
Architecturally, this instruction behaves like a NOP instruction."
On RISC-V and ARM64, CpuPause() executes a NOP, which is no worse than
the tight loop we have.

layout of the SMRAM regarding the SMM communication.

ReleaseSpinLock(&CpuMpData->MpLock);
}
When the if-check is passed, the code may call into PEI services:
1. AcquireSpinLock
When the PcdSpinTimeout is not 0, TimerLib
GetPerformanceCounterProperties() is called. And some of the
TimerLib implementations would get the information cached in
HOB. But AP procedure cannot call PEI services to retrieve the
HOB list.
2. DEBUG
Certain DebugLib relies on ReportStatusCode services and the
ReportStatusCode PPI is retrieved through the PEI services.
DebugLibSerialPort should be used.
But when SerialPortLib is implemented to depend on PEI services,
even using DebugLibSerialPort can still cause AP calls PEI
services resulting hang.
It causes a lot of debugging effort on the platform side.
There are 2 options to fix the problem:
1. make sure platform DSC chooses the proper DebugLib and set the
PcdSpinTimeout to 0. So that AcquireSpinLock and DEBUG don't call
PEI services.
2. remove the AcquireSpinLock and DEBUG call from the procedure.
Option #2 is preferred because it's not practical to ask every
platform DSC to be written properly.
Following option #2, there are two sub-options:
2.A. Just remove the if-check.
2.B. Capture the CurrentRevision and ExpectedRevision in the memory
for each AP and print them together from BSP.
The patch follows option 2.B.

OvmfPkg/CpuHotplugSmm: do actual CPU hot-eject
Add logic in EjectCpu() to do the actual the CPU ejection.
On the BSP, ejection happens by first selecting the CPU via
its QemuSelector and then sending the QEMU "eject" command.
QEMU in-turn signals the remote VCPU thread which context-switches
the CPU out of the SMI handler.
Meanwhile the CPU being ejected, waits around in its holding
area until it is context-switched out. Note that it is possible
that a slow CPU gets ejected before it reaches the wait loop.
However, this would never happen before it has executed the
"AllCpusInSync" loop in SmiRendezvous().
It can mean that an ejected CPU does not execute code after
that point but given that the CPU state will be destroyed by
QEMU, the missed cleanup is no great loss.

The reason of cloning the necessary files instead of using extern

libredfish as a C library which is executed under Windows and

replaced with EFI specific protocols (e.g. EFI_REST_EX_PROTOCOL or

interface is consumed by VariableSmmRuntimeDxe to better support variable
runtime cache feature.
This interface provides an abstration layer to allow MM modules to access
requested areas that are outside of MMRAM. On MM model that blocks all
non-MMRAM accesses, areas requested through this API will be mapped or
unblocked for accessibility inside MM environment.
For MM modules that need to access regions outside of MMRAMs, the agents
that set up these regions are responsible for invoking this API in order
for these memory areas to be accessible from inside MM.
Example usages:
1. To enable runtime cache feature for variable service, Variable MM
module will need to access the allocated runtime buffer. Thus the agent
sets up these buffers, VariableSmmRuntimeDxe, will need to invoke this
API to make these regions accessible by Variable MM.
2. For TPM ACPI table to communicate to physical presence handler, the
corresponding NVS region has to be accessible from inside MM. Once the
NVS region are assigned, it needs to be unblocked thourgh this API.

multi processor. It misses the SMM Shadow Stack Size. Each processor
will use mSmmStackSize + mSmmShadowStackSize in the memory.
It should use CpuIndex * (mSmmStackSize + mSmmShadowStackSize) to get
this SMM stack address offset. If mSmmShadowStackSize > 0 and multi
processor enabled, it will get the wrong offset value.
CET shadow stack feature will set the value of mSmmShadowStackSize.

UefiCpuPkg/CpuExceptionHandlerLib: Clear CET shadow stack token busy bit
If CET shadows stack feature enabled in SMM and stack switch is enabled.
When code execute from SMM handler to SMM exception, CPU will check SMM
exception shadow stack token busy bit if it is cleared or not.
If it is set, it will trigger #DF exception.
If it is not set, CPU will set the busy bit when enter SMM exception.
So, the busy bit should be cleared when return back form SMM exception to
SMM handler. Otherwise, keeping busy bit 1 will cause to trigger #DF
exception when enter SMM exception next time.
So, we use instruction SAVEPREVSSP, CLRSSBSY and RSTORSSP to clear the
shadow stack token busy bit before RETF instruction in SMM exception.

ArmPkg: Fix uninitialised variable in ArmMmuStandaloneMmLib
The following patches added support for StandaloneMM using FF-A: 9da5ee116a28 ArmPkg: Allow FF-A calls to set memory region's attributes 0e43e02b9bd8 ArmPkg: Allow FF-A calls to get memory region's attributes
However, in the error handling logic for the Get/Set Memory attributes,
the CLANG compiler reports that a status variable could be used without
initialisation. This issue is a false positive and is not seen with GCC.
The Get/Set Memory attributes operation is atomic and therefore an
FFA_INTERRUPT or FFA_SUCCESS response is not expected in response
to FFA_MSG_SEND_DIRECT_REQ. So the remaining cases that could occur
are:
- the target sends FFA_MSG_SEND_DIRECT_RESP with a success or
failure code.
or
- FFA_MSG_SEND_DIRECT_REQ transmission failure.
Therefore,
- reorder the error handling conditions such that it prevents the
uninitialised variable issue being flagged by CLANG.
- move the repetitive code to a static helper function and add
documentation at the appropriate places.
- fix error handling in functions that invoke GetMemoryPermissions().
The library for this header initially resided in StandaloneMmPkg
but moved to MdePkg and now this file is a duplicate of the header
file in MdePkg.
This change removes the header file from StandaloneMmPkg. More
details regarding the history of the library transitioning from
StandaloneMmPkg to MdePkg are below.
The following commit removed the library from StandaloneMmPkg: d6253d2f9a33 ("StandaloneMmPkg: remove redundant

UefiCpuPkg/MpInitLib: Use XADD to avoid lock acquire/release
When AP firstly wakes up, MpFuncs.nasm contains below logic to assign
an unique ApIndex to each AP according to who comes first:
---ASM---
TestLock:
xchg [edi], eax
cmp eax, NotVacantFlag
jz TestLock
"lock inc" cannot be used to increase ApIndex because not only the
global ApIndex should be increased, but also the result should be
stored to a local general purpose register EBX.
This patch learns from the NASM implementation of
InternalSyncIncrement() to use "XADD" instruction which can increase
the global ApIndex and store the original ApIndex to EBX in one
instruction.
With this patch, OVMF when running in a 255 threads QEMU spends about
one second to wakeup all APs. Original implementation needs more than
10 seconds.

BaseTools: Align include guards policy
The EDK II C Coding Standards Specification states that:
"Names starting with one or two underscores, such as
_MACRO_GUARD_FILE_NAME_H_, must not be used. They are
reserved for compiler implementation." [1]
The Ecc tool currently checks that the include guard end with
a trailing underscore. Thus, the check and the error message
should both be modified.
The new check forces having one sole trailing underscore
character, as the example in the specification shows:
"FILE_NAME_H_" [1]
This would allow to have more consistency.

MdeModulePkg/VariableStandaloneMm: Set PcdFlashNvStorageVariableBase to Pcd
Instead of running StMM in SPM, OP-TEE creates a new secure partition,
which emulates SPM and isolates StMM from the rest of the Trusted
Applications (TAs). We can then compile StMM as an FD image and run it
in OP-TEE. With the addition of a new RPMB driver, we can leverage OP-TEE
and store variables to an RPMB device.
Since EDK2 upper layers expect byte addressable code, for the RPMB to
work, we need to allocate memory and sync it with the hardware on
read/writes. Since DynamicPCDs are not supported in that context we
can only use PatchablePCDs. So let's switch them to Pcd instead of
FixedPcd and accomodate the new driver. While at it, move the rest
of the variables under Pcd section, instead of FixedPcd -- this is in
line with how the variables are defined in the other Variable
