Jiewen Yao 10e4e4f627 MdeModulePkg/PiSmmCore: Replace BASE_4GB with MAX_ADDRESS check.
PI specification Vol 4 - SMM does not have any limitation of BASE_4GB for SMM.
So we should replace BASE_4GB check with MAX_ADDRESS check to make sure
the SMM memory is accessible by SMM Core.

DxeSmmReadyToLock protocol installation. This update is ASSERT if EndOfDxe
Event is not signaled when DxeSmmReadyToLock protocol installed. And do

Star Zeng c03beb762a MdeModulePkg PiSmmCore: Remove a hidden assumption of SMRAM reservation
that assumes the SMRAM reserved range is only at the end of the SMRAM descriptor.

          //
          // This range has reserved area, calculate the left free size
          //
          gSmmCorePrivate->SmramRanges[Index].PhysicalSize = SmramResRegion->SmramReservedStart - gSmmCorePrivate->SmramRanges[Index].CpuStart;

Imagine the following scenario where we just reserve the first page of the SMRAM range:

SMRAM Descriptor:
  Start: 0x80000000
  Size: 0x02000000

Reserved Range:
  Start: 0x80000000
  Size: 0x00001000

In this case the adjustment to the SMRAM range size yields zero: ReservedStart - SMRAM Start is 0x80000000 - 0x80000000 = 0.
So even though most of the range is still free the IPL code decides its unusable.

The problem comes from the email thread: [edk2] PiSmmIpl SMRAM Reservation Logic.
http://thread.gmane.org/gmane.comp.bios.tianocore.devel/15268

Also to follow the idea in the email thread, the patch is to
1. Keep only one copy of full SMRAM ranges in gSmmCorePrivate->SmramRanges,
split record for SmmConfiguration->SmramReservedRegions and SMM Core that
will be marked to be EFI_ALLOCATED in gSmmCorePrivate->SmramRanges.
2. Handle SmmConfiguration->SmramReservedRegions at beginning of, at end of,
in the middle of, or cross multiple SmramRanges.

Star Zeng 53ec4d7f98 MdeModulePkg PiSmmCore: Introduce SMM Exit Boot Services and Legacy Boot.
And also SMM Ready To Boot.

The SMM Exit Boot Service protocol is to be published by the SMM
Foundation code to associate with EFI_EVENT_GROUP_EXIT_BOOT_SERVICES
to notify SMM driver that system enter exit boot services.

The SMM Legacy Boot protocol is to be published by the SMM
Foundation code to associate with EFI_EVENT_LEGACY_BOOT_GUID
to notify SMM driver that system enter legacy boot.

The SMM Ready To Boot protocol is to be published by the SMM
Foundation code to associate with EFI_EVENT_GROUP_READY_TO_BOOT
to notify SMM driver that system enter ready to boot.

After them, any SMM drivers can get protocol notify on what happened
in DXE phase, then there is no need to let each individual SMM driver
to register SMM Communication Handler for that.

2. Move pool and page management definitions and structures

PiSmmCorePrivateData.h should be only used to share SMM_CORE_PRIVATE_DATA

and structures were moved from Pool.c and Page.c to PiSmmCorePrivateData.h

Laszlo Ersek b07ea4c198 MdeModulePkg: SmmIplEntry(): don't suppress SMM core startup failure
When the ExecuteSmmCoreFromSmram() function fails, SmmIplEntry()
restores the SMRAM range to EFI_MEMORY_UC. However, it saves the
return value of gDS->SetMemorySpaceAttributes() in the same Status
variable that gDS->contains the return value of ExecuteSmmCoreFromSmram().

Therefore, if gDS->SetMemorySpaceAttributes() succeeds, the failure
of ExecuteSmmCoreFromSmram() is masked, and Bad Things Happen (TM).

Introduce a temporary variable just for the return value of
gDS->SetMemorySpaceAttributes().
