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.
