2026-05-06T10:43:05+00:00

All debug prints should end in a newline character. Signed-off-by: Benjamin Doron

MdeModulePkg: Remove duplicate procotols guid in INF files

2026-04-29T09:18:10+00:00

In PciSioSerialDxe driver, gEfiDevicePathProtocolGuid appears twice in [Procotols] section. In PiSmmCore driver, gEfiSmmSxDispatch2ProtocolGuid appears twice in [Procotols] section. In PiSmmIpl driver, gEfiEventReadyToBootGuid appears twice in [Procotols] section. In DxeCapsuleLib driver, gEfiCapsuleVendorGuid appears twice in [Guids] section. The duplicate ones should be removed. Signed-off-by: Qihang Gao

MdeModulePkg: Don't Allow Guard Pages to Cross Bin Boundaries

2026-04-23T02:42:12+00:00

Currently, the DXE page allocator does not ensure that guard page allocations stay within the bin that it is attempting to allocate within. As a result, S4 resume is jeopardized by bins expanding due to guard pages, either into other bins or out of bins. This is caught by a new assert in CoreGetMemoryMap() to ensure the bins are correct. This fixes this by changing the internal heap guard API to return the adjusted size and start address of a proposed allocation. The page allocator then can ensure that the adjusted allocation still fits within the bin it is attempting to allocate within; if not, it will search for another descriptor.

MdeModulePkg/Core: Validate DXE event signature before usage

2026-03-23T18:43:11+00:00

fixes: #11112 Currently, function RegisterProtocolNotify() doesn't check the validity of event and it accepts any event pointer as long as pointer isn't NULL. However event could be closed and freed which could lead to use after free. Always check event signature before usage and return EFI_INVALID_PARAMTER for events with invalid signature.

MdeModulePkg/PeiCore: Accept MemoryDiscoveredPpi from SecCore

2026-03-19T02:02:47+00:00

PeiCore assumes that it runs initially from the temporary memory and switches to physical memory after PS::InstallPeiMemory() reports the physical memory range for PEI. This change enables PeiCore to run initially from the physical memory when MemoryDiscoveredPpi is passed from SEC. Signed-off-by: Ray Ni

MdeModulePkg: Update performance measurements to use new perf macros

2026-03-17T02:38:07+00:00

Updates BmBoot and dispatcher to use new perf macros. Signed-off-by: Sherry Fan

MdeModulePkg/Core: Increment handle key outside if block

2026-03-09T09:19:06+00:00

Fixes: #11113 Currently, the global handle key and key inside handle structure is incremented only when a new handle is allocated for protocol interface to be installed. However, when caller already supplies a handle gHandleDatabaseKey never get incremented. Move handle key incremental outside if block, just below the else statement which allows gHandleDatabaseKey to always incremented whether handle is supplied or not. Signed-off-by: Khalid Ali

MdeModulePkg: DxeIpl IA32: Use 256 IDT Entries

2026-03-07T03:58:40+00:00

When IA32 DxeIpl is setting up the IDT, it should populate 256 entries, the architectural size, so that exceptions are handled in a defined way, going to the common exception handler. This includes the stack cookie exception. Signed-off-by: Oliver Smith-Denny

MdeModulePkg: DxeMain: Check memory type overlap inside CoreGetMemoryMap

2026-02-28T04:20:00+00:00

This change adds validation to CoreGetMemoryMap to ensure that special memory bins are fully respected. Specifically, any memory map entry that falls within a special bin must be entirely contained within that bin, and its memory type must match the bin's designated type. This check helps preventing unintended changes that could cause the system memory map to cross bin boundaries unexpectedly. Signed-off-by: Kun Qin

MdeModulePkg/Core: Move SMI depth tracker below SMI presence check

2026-02-27T06:09:41+00:00

Fixes: #11764 Currently, mSmiManageCallingDepth is incremented always whether SMI handler is present or not. However get decremented only when SMI handler is found. This causes mSmiManageCallingDepth to grow infinitely as long as SMI handler isn't present. Increment mSmiManageCallingDepth only when SMI handler presence is confirmed. Signed-off-by: Khalid Ali
