REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4677 Attacker able to modify physical memory and ResumeCount. System will crash/DoS when ResumeCount reaches its MAX_UINT32. Cc: Zhiguang Liu Cc: Dandan Bi Cc: Liming Gao Signed-off-by: Pakkirisamy ShanmugavelX Reviewed-by: Liming Gao

MdeModulePkg/AcpiTableDxe: Prefer xDSDT over DSDT when installing tables

2024-04-11T08:04:45+00:00

As per ACPI Spec 6.5+ Table 5-9 if xDSDT is available, it should be used first. Handle required flow when xDSDT is absent or present. Test: Tested on RISCV64 Qemu platform with xDSDT and booted to linux kernel.

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/FPDT: Lock boot performance table address variable at EndOfDxe

2021-11-12T07:36:23+00:00

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2957 1. Allocate performance data table at EndOfDxe and then lock the varible which store the table address at EndOfDxe. 2. Enlarge PCD gEfiMdeModulePkgTokenSpaceGuid.PcdExtFpdtBootRecordPadSize from 0x20000 to 0x30000 in order to hold the Delta performance data between EndOfDxe and ReadyToBoot. 3. SMM performance data is collected by DXE modules through SMM communication at ReadyToBoot before. Now to do SMM communication twice, one for allocating the performance size at EndOfDxe, another is at ReadyToBoot to get SMM performance data. 4. Make SmmCorePerformanceLib rather than FirmwarePerformanceSmm to communicate with DxeCorePerformanceLib for SMM performance data and size.

MdeModulePkg/ACPI: Install ACPI table from HOB.

2021-06-16T05:20:19+00:00

If HOB contains APCI table information, entry point of AcpiTableDxe.inf should parse the APCI table from HOB, and install these tables. We assume the whole ACPI table (starting with EFI_ACPI_2_0_ROOT_SYSTEM_DESCRIPTION_POINTER) is contained by a single gEfiAcpiTableGuid HOB. If error happens when installing ACPI table, stop installing and removing all the tables that are already added.
