MdeModulePkg: Add platform limit for size in Resizable BAR

2026-02-25T03:40:14+00:00

Resizable BAR driver selects max available BAR size to configure for use. It may happen that some PCIe device declare support for size that exceeds processor address width. Platform needs a way to define the max size it can accept. This change introduce PCD called PcdPcieResizableBarMaxSize. It is dynamic PCD where platform can provide its limit for BAR size. Such PCD can be also controlled with a configuration knob. Signed-off-by: Jacek Kolakowski

MdeModulePkg: Remove UGA support

2025-07-08T15:42:03+00:00

The Universal Graphics Adapter (UGA) is a graphic abstraction. The UGA I/O and Draw protocols are deprecated since UEFI 2.0 was introduced. Cf. the UEFI spec v2.9: "Appendix L - EFI 1.10 Protocol Changes and Deprecation List" section L.2 "Deprecated Protocols" Remove the UGA support. Signed-off-by: GuoMinJ Signed-off-by: Pierre Gondois

MdeModulePkg/AcpiTableDxe: PCD switch to avoid using ACPI reclaim memory

2024-04-09T07:03:08+00:00

UEFI spec defined ACPI Tables at boot time can be contained in memory of type EfiACPIReclaimMemory or EfiAcpiMemoryNVS, although InstallAcpiTable with AcpiTableProtocol will only allocate memory with type EfiACPIReclaimMemory (Except FACS). This patch provides an optional method controlled by PCD to avoid using EfiACPIReclaimMemory, by setting the PCD PcdNoACPIReclaimMemory to TRUE, all ACPI allocated memory will use EfiAcpiMemoryNVS instead.

MdeModulePkg: Use configurable PCD for AHCI command retries

2022-09-13T02:51:27+00:00

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4011 AHCI commands are retried internally which prevents platform feature like drive password to process correctly entered password on subsequent attempts. PCD allows the platform to determine the number of retries. Signed-off-by: Baraneedharan Anbazhagan Reviewed-by: Hao A Wu

MdeModulePkg/Core/Dxe: limit FwVol encapsulation section recursion

2020-11-21T01:40:53+00:00

The DXE Core sets up a protocol notify function in its entry point, for instances of the Firmware Volume Block2 Protocol: DxeMain() [DxeMain/DxeMain.c] FwVolDriverInit() [FwVol/FwVol.c] Assume that a 3rd party UEFI driver or application installs an FVB instance, with crafted contents. The notification function runs: NotifyFwVolBlock() [FwVol/FwVol.c] installing an instance of the Firmware Volume 2 Protocol on the handle. (Alternatively, assume that a 3rd party application calls gDS->ProcessFirmwareVolume(), which may also produce a Firmware Volume 2 Protocol instance.) The EFI_FIRMWARE_VOLUME2_PROTOCOL.ReadSection() member performs "a depth-first, left-to-right search algorithm through all sections found in the specified file" (quoting the PI spec), as follows: FvReadFileSection() [FwVol/FwVolRead.c] GetSection() [SectionExtraction/CoreSectionExtraction.c] FindChildNode() [SectionExtraction/CoreSectionExtraction.c] FindChildNode() // recursive call FindChildNode() is called recursively for encapsulation sections. Currently this recursion is not limited. Introduce a new PCD (fixed-at-build, or patchable-in-module), and make FindChildNode() track the section nesting depth against that PCD.
