(

IN EFI_ACPI_TABLE_PROTOCOL *

AcpiProtocol

)

Get Xen Acpi tables from the RSDP structure. And installs Xen ACPI tables into the RSDT/XSDT using InstallAcpiTable. Some signature of the installed ACPI tables are: FACP, APIC, GTDT, DSDT.

Parameters

AcpiProtocol

Protocol instance pointer.

Returns

EFI_SUCCESS The table was successfully inserted.

EFI_INVALID_PARAMETER Either AcpiTableBuffer is NULL, TableHandle is NULL, or AcpiTableBufferSize and the size field embedded in the ACPI table pointed to by AcpiTableBuffer are not in sync.

EFI_OUT_OF_RESOURCES Insufficient resources exist to complete the request.
