Subject: [PATCH 0/2] Let AcpiTableDxe driver install Acpi table from Hob
Date: Tue, 23 Mar 2021 10:49:32 +0800 [thread overview]
Message-ID: <20210323024934.853-1-zhiguang.liu@intel.com> (raw)
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.
This way, for UefiPayloadPkg, there is no need to specially hanle acpi table.
