What's Changed

MdeModulePkg/Variable: Move RT cache buffer allocation to DXE @makubacki (#1519)

Change Details

Description

Commit d8f513de3e3ef228af7e6facf0ad3e35c3224032 (an edk2 commit) added runtime memory allocation to VariablePei. That will cause runtime memory bucket fragmentation affecting hibernate stability as these runtime allocations are separate from the main runtime memory type bucket allocation made by the DXE Core.

To preserve the existing functionality but allow the runtime buffer to come from the DXE bucket, the allocations in PEI are changed to boot services data allocations and the contents are moved to the runtime memory buffers (and those pages unblocked to MM) in the DXE variable driver after the bucket has been allocated by the DXE core.

---

> Note: I will upstream this to edk2 but it is urgently needed in Project Mu.

Fix alignment of PE/COFF image address to section alignment @rohitkr89 (#1580)

Change Details

Description

With MSVC 14.44.35207, & operation for section alignment is causing compilation failure : MdeModulePkg\Core\Pei\Image\Image.c(405): '~': zero extending 'UINT32' to 'PHYSICAL_ADDRESS' of greater size. Use EFI_PHYSICAL_ADDRESS instead of UINTN for ImageAddress assignment to get proper masking address for section alignment.

[Rebase \& FF] Adding a communication buffer update protocol to save memory fragmentation @kuqin12 (#1571)

Change Details

Description

The current Standalone MM model does not coalesce the runtime memory when the unblock memory request in PEI allocate runtime memory. This will lead to fragmented memory map and potentially hibernation failure.

This change adds a protocol definition that allows an event to be signaled when all the PEI-allocated runtime memory migrate to permanent runtime memory.

This change also adds a byte in the communication buffer status to differentiate the target.
