MdeModulePkg: Add PcdDelayedDispatchMaxEntries

2025-09-23T01:02:04+00:00

The current fixed value of 8 for `DELAYED_DISPATCH_MAX_ENTRIES` is not large enough to accommodate platform usage. This change replaces the macro with a PCD that can be configured by platforms. In the case the default PCD value is too small, an error message explaining that the PCD should be updated will be printed followed by an assert. Signed-off-by: Michael Kubacki

MdeModulePkg/Library: fix memory leak Rx/Tx Buffer in ArmFfaPeiLib

2025-07-14T11:59:38+00:00

The commit e15fe066036da ("MdeModulePkg/Library: make ArmFfaPeiLib available early PEIM stage") uses ArmFfaPeiLib in the early PEIM stage. However, the Rx/Tx buffer allocated in the early PEIM stage uses temporary memory. This results in a memory leak when the temporary memory's heap is relocated to permanent memory. For example, if the Rx/Tx buffer memory is allocated at 0x20006000 in temporary memory, and if offset between temporary memory and permanent is 0x40000000, then: - Once permanent memory installed the temporary memory at 0x20006000 is migrated to 0x60006000. - However, ArmFfaPeiLib allocates new Rx/Tx buffer without freeing the migrated Rx/Tx buffers, i.e. the buffers at 0x60006000. This results in a memory leak as the migrated Rx/Tx buffer area is lost. To address this memory leak, use the MemoryAllocationHob's name, so that the migrated memory area will be reused as Rx/Tx buffer. This patch also includes rename ArmFfaRxTxStmm.c to ArmFfaStandaloneMmRxTxMap.c to keep the file name convention in ArmFfaLib with ArmFfa{Phase}{...}.c Fixes: e15fe066036da ("MdeModulePkg/Library: ...")

MdeModulePkg: VariableSmmRuntimeDxe: Use MM communicate v3

2025-06-26T21:43:56+00:00

As MM cores start to support MM communciate v3. This change moves the variable driver to use MM communicate v3 if it is available, otherwise the driver will fallback to v2 to keep the same functionality. Signed-off-by: Kun Qin

MdeModulePkg: Update MM buffer structs alignment

2025-04-14T08:44:05+00:00

In general, for all HOB related content, the HOB structures must be designed so that natural alignment across all execution modes and byte-packed alignment are the same. Ensure ReturnStatus is aligned on 64 bit to achieve the same. Signed-off-by: Dhaval Sharma

MdeModulePkg: ArmFfaLib: Move Rx/Tx hob definition to Include/Guid folder

2025-04-10T17:52:48+00:00

Currently, ArmFfaLib uses an internally defined Guided HOB to pass information about the Rx/Tx buffer set up by the first executing agent. However, the GUID definition is solely specified in the DEC file, which is inconsistent with other GUID definitions in MdeModulePkg. This change relocates the GUID definition to the Include/Guid folder to ensure consistency across the package. Signed-off-by: Kun Qin

MdeModulePkg: PeiMain: Introduce implementation of delayed dispatch

2024-10-17T08:51:15+00:00

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4496 This change adds the implementation that fits the needs and description of PI spec defined Delayed Dispatch PPI in Pei Core. The PPI would allow minimal delay for registered callbacks. As well as allowing other functions to wait for GUIDed delayed dispatch callbacks.

MdeModulePkg: Add MM Communication Buffer definition

2024-08-28T15:25:27+00:00

The MM communicate buffer facilitates data sharing between non-MM and MM code. The MM IPL code allocates a "fixed" runtime type memory as the MM communication buffer, and communicates its address and size to MM Core via MmCommBuffer GUIDed HOB. Here, "fixed" implies that the buffer's location remains constant throughout the boot process. Data is exchanged between the MM Communication PPI/Protocol and a software MMI handler using this fixed MM communication buffer.

MdeModulePkg: Optimize PEI Core Migration Algorithm

2024-07-30T13:51:41+00:00

REF : https://bugzilla.tianocore.org/show_bug.cgi?id=4750 Migrate the FV that doesn't contain the currently executing PEI Core when permanent memory is initialized but PEI Core is still potentially running from faster memory (Tepmorary RAM). This may reduce the time required to migrate FVs to permanent memory. The FV containing PEI Core is migrated after the PEI Core reentry when it is executed from permanent memory. This may or may not improve performance depending on the behavior of temporary RAM and the actual performance changes must be measured with the feature enabled and disabled. This migration algorithm is only used for FVs specified in the gEdkiiMigrationInfoGuid HOB and built with flag FLAGS_FV_MIGRATE_BEFORE_PEI_CORE_REENTRY. Signed-off-by: Awiral Shrivastava

MdeModulePkg: Add NVMe Long Delay Time Events

2024-07-27T01:32:21+00:00

Fire an event if a long delay occurs when starting an NVMe device. This can be used by platforms to draw pictures on the screen or take other actions to notify a user or move boot forward. Signed-off-by: Oliver Smith-Denny
