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/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.

MdeModulePkg/AcpiTableDxe: use pool allocation for RSDP if possible

2020-10-30T14:50:33+00:00

Use a pool allocation for the RSDP ACPI root pointer structure if no memory limit is in effect that forces us to use page based allocation, which may be wasteful if they get rounded up to 64 KB as is the case on AArch64. Signed-off-by: Ard Biesheuvel Reviewed-by: Liming Gao

MdeModulePkg/AcpiTableDxe: use pool allocation for RSDT/XSDT if possible

2020-10-30T14:50:33+00:00

If no memory allocation limit is in effect for ACPI tables, prefer pool allocations over page allocations, to avoid wasting memory on systems where page based allocations are rounded up to 64 KB, such as AArch64. Signed-off-by: Ard Biesheuvel Reviewed-by: Liming Gao

MdeModulePkg/AcpiTableDxe: use pool allocations when possible

2020-10-30T14:50:33+00:00

On AArch64 systems, page based allocations for memory types that are relevant to the OS are rounded up to 64 KB multiples. This wastes some space in the ACPI table memory allocator, since it uses page based allocations in order to be able to place the ACPI tables low in memory. Since the latter requirement does not exist on AArch64, switch to pool allocations for all ACPI tables except the root tables if the active allocation policy permits them to be anywhere in memory. The root tables will be handled in a subsequent patch. Signed-off-by: Ard Biesheuvel Reviewed-by: Liming Gao
