| DSDT (Differentiated System Description Table) | Parsed by `acpi` crate AML interpreter | Working | Platform-specific device config via AML bytecode |
| SSDT (Secondary System Description Table) | Parsed by `acpi` crate AML interpreter | Working | Secondary AML tables (hotplug, etc.) |

IVRS was previously listed as "implemented" but the stub was broken. It has been removed
from acpid. IVRS needs a real AMD IOMMU driver (P5+ scope). MCFG is now handled by
pcid's /config endpoint (P1 complete) which provides direct PCI config space access.
