Definitions for the ACPI table

RSDT is the Root System Descriptor Table, whereas XSDT is the Extended System Descriptor Table. They are identical except that the XSDT uses 64-bit physical addresses to point to other ACPI SDTs, while the RSDT uses 32-bit physical addresses.

Structs

  • AcpiTables
    The struct holding all ACPI tables and records of where they exist in memory. All ACPI tables are covered by a single large MappedPages object, which is necessary because they may span multiple pages/frames, and generally should not be multiply aliased/accessed due to potential race conditions. As more ACPI tables are discovered, the single MappedPages object is extended to cover them.
  • TableLocation
    A record that tracks where an ACPI Table exists in memory, given in terms of offsets into the AcpiTables’s MappedPages.

Type Aliases

  • AcpiSignature
    All ACPI tables are identified by a 4-byte signature, typically an ASCII string like “APIC” or “RSDT”.
