Add interrupt-enable recursion depth tracking using
mInterruptEnableNestDepth and a bounded assertion in
CoreSetInterruptState().
This provides early detection for unintended recursive
interrupt-enable loops.

Refactor the CoreSetInterruptState(TRUE) flow so EnableInterrupt() is
invoked through a single call site.
Behavior is unchanged: interrupts remain disabled in SMM and are enabled
outside SMM.

MdeModulePkg: MemoryBins: make GoogleTest page-granularity aware2026-07-31T15:16:47+00:00Jeff Brasenjbrasen@nvidia.com2026-07-20T20:54:49+00:00urn:sha1:ca8de19382c668cf8770ee788478edcd8a22d0e7
MemoryBinGoogleTest.PopulatesFromValidHob asserted fixed page counts for
each memory type. PopulateMemoryTypeInformation, however, rounds the
runtime memory types (EfiReservedMemoryType, EfiACPIMemoryNVS,
EfiRuntimeServicesCode, EfiRuntimeServicesData) up to
RUNTIME_PAGE_ALLOCATION_GRANULARITY. That granularity equals EFI_PAGE_SIZE
on IA32/X64, so the hard-coded values happened to match, but it is 64 KiB
on AArch64, where the same inputs round up to different page counts and the
test failed.
Compute the expected page counts with the same granularity rounding the
production code uses, so the test passes on all host architectures instead
of only x86.

MdeModulePkg: Dxe Core: Correct gMemoryTypeInformation Definition2026-07-09T12:46:51+00:00Oliver Smith-Dennyosde@microsoft.com2026-06-22T14:05:40+00:00urn:sha1:c38340a0c198e8e5c07a3820796c624109060b96
Commit 43e306806e3c1ed3ad7e9913492732e893cafa0f added support
to DXE Core for EfiUnacceptedMemoryType. However, it incorrectly
added EFI_GCD_MEMORY_TYPE_UNACCEPTED to gMemoryTypeInformation,
which is the GCD memory type that is associated with
EfiUnacceptedMemoryType. All other changes from that PR
appear correct.
This is corrected to the EFI memory type.
The Memory Bin Google Test copied this incorrect definition,
so it is updated as well.

MdeModulePkg: DxeCore: Update Memory Statistics from PEI2026-06-24T15:53:58+00:00Oliver Smith-Dennyosde@microsoft.com2026-01-29T17:51:48+00:00urn:sha1:cf1a2a541e1fa19a0117a952fece30de1928caae
If memory bins are enabled for PEI, PEI will produce
Memory Allocation HOBs marked with gEfiMemoryTypeInformationGuid.
If these exist, DXE core will now process the stats from them
to have accurate numbers.

MdeModulePkg: Dxe Core: Split Memory Bin Logic Into Separate File2026-06-24T15:53:58+00:00Oliver Smith-Dennyosde@microsoft.com2026-06-18T16:32:27+00:00urn:sha1:eab3300622876b674cf22c5c56f899b0a6df1087
This commits splits out logic currently contained in
Gcd.c and Page.c to a new file called
MemoryBin.c. This is set up in preparation to
add support to PEI for memory bins (an S4 resume stability
feature).
MemoryBin.c takes all global state in as parameters so that
DXE core can use globals and PEI core can use HOBs.
There is no logic change here, just consolidating the
functionality to share with PEI.
This was requested not to be a library.

This commit adds a parameter to the memory bin allocation function
to tell it whether it should create the Resource Descriptor HOB
owned by gMemoryTypeInformationGuid. This will be used by PEI to
tell DXE where the memory bins are.

This adds a helper function to initialize the
memory bin statistics as the same logic is

MdeModulePkg: Dxe Core: Prep CoreSetMemoryTypeInformationRange for PEI2026-06-24T15:53:58+00:00Oliver Smith-Dennyosde@microsoft.com2026-05-12T21:27:09+00:00urn:sha1:81bec6f0fbf686fa94b193eb16cba4729dfbc98b
Migrate CoreSetMemoryTypeInformationRange() to not use globals so
it can be used in PEI as well.
This temporarily moves the EFI_MEMORY_STATISTICS structure to
DxeMain.h so that it can be used in Gcd.c as well as Page.c.
This will migrate to a different private header once that is included.
