The patch moves all files under UefiCpuPkg/Include/Register/ to
MdePkg/Include/Register using following detailed approaches:
1. Move UefiCpuPkg/Include/Register/Amd/ to
MdePkg/Include/Register/Amd folder.
2. Move remaining in UefiCpuPkg/Include/Register/ to
MdePkg/Include/Register/Intel folder.
3. Create wrapper header files under UefiCpuPkg/Include/Register/
to include the accordingly files in MdePkg/Include/Register/Intel.
This is to avoid build break because code in other repos like
edk2-platform includes the file from UefiCpuPkg.
The wrapper header files will be removed after all consumers code
is updated.

Previously, when compiling NASM source files, BaseTools did not support
including files outside of the NASM source file directory. As a result, we
duplicated multiple copies of "StuffRsb.inc" files in UefiCpuPkg. Those
INC files contain the common logic to stuff the Return Stack Buffer and
are identical.
After the fix of BZ 1085:
https://bugzilla.tianocore.org/show_bug.cgi?id=1085
The above support was introduced.
Thus, this commit will merge all the StuffRsb.inc files in UefiCpuPkg into
one file. The merged file will be named 'StuffRsbNasm.inc' and be placed
under folder UefiCpuPkg/Include/.

v3 changes:
1. Move CPU_FEATURE_DEPENDENCE_TYPE definition here from RegisterCpuFeaturesLib.h file.
2. Add Invalid type for REGISTER_TYPE which will be used in code.
v2 changes:
1. Add more description about why we do this change.
2. Change structure field type from pointer to EFI_PHYSICAL_ADDRESS because it will
be share between PEI and DXE.
v1 Changes:
In order to support semaphore related logic, add new definition for it.
In a system which has multiple cores, current set register value task costs huge times.
After investigation, current set MSR task costs most of the times. Current logic uses
SpinLock to let set MSR task as an single thread task for all cores. Because MSR has
scope attribute which may cause GP fault if multiple APs set MSR at the same time,
current logic use an easiest solution (use SpinLock) to avoid this issue, but it will
cost huge times.
In order to fix this performance issue, new solution will set MSRs base on their scope
attribute. After this, the SpinLock will not needed. Without SpinLock, new issue raised
which is caused by MSR dependence. For example, MSR A depends on MSR B which means MSR A
must been set after MSR B has been set. Also MSR B is package scope level and MSR A is
thread scope level. If system has multiple threads, Thread 1 needs to set the thread level
MSRs and thread 2 needs to set thread and package level MSRs. Set MSRs task for thread 1
and thread 2 like below:
Thread 1 Thread 2
MSR B N Y
MSR A Y Y
If driver don't control execute MSR order, for thread 1, it will execute MSR A first, but
at this time, MSR B not been executed yet by thread 2. system may trig exception at this
time.
In order to fix the above issue, driver introduces semaphore logic to control the MSR
execute sequence. For the above case, a semaphore will be add between MSR A and B for
all threads. Semaphore has scope info for it. The possible scope value is core or package.
For each thread, when it meets a semaphore during it set registers, it will 1) release
semaphore (+1) for each threads in this core or package(based on the scope info for this
semaphore) 2) acquire semaphore (-1) for all the threads in this core or package(based
on the scope info for this semaphore). With these two steps, driver can control MSR
sequence. Sample code logic like below:
//
// First increase semaphore count by 1 for processors in this package.
//
for (ProcessorIndex = 0; ProcessorIndex < PackageThreadsCount ; ProcessorIndex ++) {
LibReleaseSemaphore ((UINT32 *) &SemaphorePtr[PackageOffset + ProcessorIndex]);
}
//
// Second, check whether the count has reach the check number.
//
for (ProcessorIndex = 0; ProcessorIndex < ValidApCount; ProcessorIndex ++) {
LibWaitForSemaphore (&SemaphorePtr[ApOffset]);
}
Platform Requirement:
1. This change requires register MSR setting base on MSR scope info. If still register MSR
for all threads, exception may raised.
Known limitation:
1. Current CpuFeatures driver supports DXE instance and PEI instance. But semaphore logic
requires Aps execute in async mode which is not supported by PEI driver. So CpuFeature
PEI instance not works after this change. We plan to support async mode for PEI in phase
2 for this task.

ACPI_CPU_DATA structure first introduced to save data in
normal boot phase. Also this data will be used in S3 phase
by one PEI driver. So in first phase, this data is been
defined to use ACPI NVS memory type and must below 4G.
Later in order to fix potential security issue,
PiSmmCpuDxeSmm driver added logic to copy ACPI_CPU_DATA
(except ResetVector and Stack buffer) to smram at smm
ready to lock point. ResetVector must below 1M and Stack
buffer is write only in S3 phase, so these two fields not
copy to smram. Also PiSmmCpuDxeSmm driver owned the task
to restore the CPU setting and it's a SMM driver.
After above change, the acpi nvs memory type and below 4G
limitation is no longer needed.
This change remove the limitation in the comments for

The new algorithm converts the problem calculating optimal
MTRR settings (using least MTRR registers) to the problem finding
the shortest path in a graph.
The memory required in extreme but rare case can be up to 256KB,
so using local stack buffer is impossible considering current
DxeIpl only allocates 128KB stack.
The patch changes existing MtrrSetMemoryAttributeInMtrrSettings() and
MtrrSetMemoryAttribute() to use the 4-page stack buffer for
calculation. The two APIs return BUFFER_TOO_SMALL when the buffer
is too small for calculation.
The patch adds a new API MtrrSetMemoryAttribute*s*InMtrrSettings() to
set multiple-range attributes in one function call.
Since every call to MtrrSetMemoryAttributeInMtrrSettings (without-s)
or MtrrSetMemoryAttribute() requires to calculate the MTRRs for the
whole physical memory, combining multiple calls in one API can
significantly reduce the calculation time.
In theory, if N times of call to without-s API costs N seconds,
the new API only costs 1 second.
The new API uses the buffer supplied from caller to calculate
MTRRs and returns BUFFER_TOO_SMALL when the buffer is too small for
calculation.
Test performed:
1. Random test
a. Generate random memory settings, use the new algorithm to
calculate the MTRRs.
b. Read back the MTRRs and check the memory settings match
the desired memory settings.
c. Repeat the above #1 and #2 100000 times.
2. OVMF 32PEI + 64DXE boot to shell.
