Module acpi 

ACPI table parser for x86_64.

Parses ACPI tables from UEFI firmware to discover hardware topology:

• MADT (Multiple APIC Description Table): CPU enumeration, I/O APIC, ISA overrides
• MCFG (PCI Express config space base addresses)

Not in scope: Full AML interpreter, ACPI namespace, runtime ACPI methods.

Structs

AcpiInfo

Parsed ACPI information, populated by init().

MadtIoApic

I/O APIC entry from the MADT.

MadtIso

Interrupt Source Override entry from the MADT.

MadtLocalApic

Local APIC entry from the MADT.

McfgEntry

PCIe Enhanced Configuration Mechanism entry from MCFG.

Functions

dump

Dump parsed ACPI information to the console (for the acpi shell command).

find_madt_cpus

Find MADT CPU topology data.

find_slit

Find SLIT table data. Returns a slice of the raw SLIT table if present.

find_srat

Find SRAT table data. Returns a slice of the raw SRAT table if present.

init

Initialize the ACPI subsystem by parsing tables from the RSDP address provided by the UEFI bootloader.

is_initialized

Check whether ACPI tables have been parsed.

with_acpi_info

Access the parsed ACPI info. Returns None if not initialized.
