struct ACPI::RSDP

Root System Description Pointer (RSDP)

The first step to using ACPI is finding the RSDP that is used to find the RSDT / XSDT, which themselves contain pointers to even more tables.

On UEFI systems, the RSDP can be found in the EFI_SYSTEM_TABLE; for non-UEFI systems we have to search for the signature 'RSD PTR ' in the EBDA (Extended Bios Data Area) or in the memory area up to FFFFFh.

struct ACPI::Address

ACPI address format.

The ACPI standard defines its own address format that is able to handle addresses both in memory address space, as well as IO-port address space.
