Jiaxin Wu d480f106a6 UefiCpuPkg/PiSmmCpuDxeSmm: Get SmmCpuSyncConfig data from func
MM can not use the dynamic PCD (PcdCpuSmmSyncMode &
PcdCpuSmmApSyncTimeout & PcdCpuSmmApSyncTimeout2), so, move to
DxeSmm code and implement in GetSmmCpuSyncConfigData function.

Jiaxin Wu cd29383f77 UefiCpuPkg/PiSmmCpuDxeSmm: Rename PiSmmCpuDxeSmm.h to PiSmmCpuCommon.h
Rename the file PiSmmCpuDxeSmm.h to PiSmmCpuCommon.h to facilitate
common usage in both SMM and MM. The renamed file PiSmmCpuCommon.h
will be utilized for both modes in subsequent patches.

No function impact.

Yanbo Huang f8bf46be59 UefiCpuPkg/PiSmmCpuDxeSmm: Consume PcdCpuSmmApSyncTimeout2
This patch is to consume the PcdCpuSmmApSyncTimeout2 to
enhance the flexibility of timeout configuration.
In some cases, certain processors may not be able to enter
SMI, and prolonged waiting could lead to kernel soft/hard
lockup. We have now defined two timeouts. The first timeout
can be set to a smaller value to reduce the waiting period.
Processors that are unable to enter SMI will be woken up
through SMIIPL to enter SMI, followed by a second waiting
period. The second timeout can be set to a larger value to
prevent delays in processors entering SMI case due to the
long instruction execution.

This patch adjust the location of PcdCpuSmmApSyncTimeout2
to avoid conflict.

Yanbo Huang 4efcd654ec Revert "UefiCpuPkg/PiSmmCpuDxeSmm: Consume PcdCpuSmmApSyncTimeout2"
This reverts commit cb3134612d.
Intel server platform sync this commit will hit conflict since our code base is old.
We don't want to cherry-pick the dependent patches to avoid potential issue.
We need to revert this commit first and then fix the conflict and reapply the change.
Sorry for the incovenience.

Michael Kinney 529a5a8609 UefiCpuPkg: Add PiSmmCpuDxeSmm module no IA32/X64 files
Add module that initializes a CPU for the SMM environment and
installs the first level SMI handler.  This module along with the
SMM IPL and SMM Core provide the services required for
DXE_SMM_DRIVERS to register hardware and software SMI handlers.

CPU specific features are abstracted through the SmmCpuFeaturesLib

Platform specific features are abstracted through the
SmmCpuPlatformHookLib

Several PCDs are added to enable/disable features and configure
settings for the PiSmmCpuDxeSmm module

Changes between [PATCH v1] and [PATCH v2]:
1) Swap PTE init order for QEMU compatibility.
   Current PTE initialization algorithm works on HW but breaks QEMU
   emulator.  Update the PTE initialization order to be compatible
   with both.
2) Update comment block that describes 32KB SMBASE alignment requirement
   to match contents of Intel(R) 64 and IA-32 Architectures Software
   Developer's Manual
3) Remove BUGBUG comment and call to ClearSmi() that is not required.
   SMI should be cleared by root SMI handler.
