Red Bear OS 6571df7802 acpi-rs: eliminate all AML stubs (resource descriptors, ConnectionField, Match, Index ref)
resource.rs — implement all ~20 stubbed resource descriptor parsers:
  - QWord/DWord/Word AddressSpace, IRQ, DMA, I/O, FixedI/O, FixedDMA
  - StartDependentFunctions, VendorDefined (small+large)
  - GPIOConnection, GenericSerialBus (I2C/SPI/UART subtypes)
  - PinFunction, PinConfiguration, PinGroup, PinGroupFunction, PinGroupConfiguration
  - ExtendedAddressSpace, GenericRegister
  - Both large/small dispatch tables now call real parsers
  - ACPI 6.5 §6.4 coverage complete, cross-referenced with ACPICA amlresrc.h

mod.rs — eliminate 3 remaining stubs:
  - ConnectionField in parse_field_list: namestring + inline buffer forms
  - Opcode::Match: full opcode handler with ResolveBehaviour::ByteData intercept,
    10-arg OpInFlight, do_match executor with 7 match operators
  - ReferenceKind::Index in do_copy_object: merged with Named/Local path

virtio-core: replace arch stubs (aarch64, riscv64) with real Error::Probe returns

usbscsid/uas: full UAS transport implementation (1006 lines) replacing
stub-heavy version — IUs, pipe detection, stream/non-stream modes,
task tag management, cross-referenced with Linux 7.1 uas.c

initnsmgr: Rc<RefCell<>> -> Arc<Mutex<>> for namespace concurrency safety

xhcid/quirks: fix comment (3 hci_version-dependent entries, not 2)

cargo check -p acpi: clean (3 pre-existing warnings only)
cargo test -p acpi --lib: 5/5 pass

Acpi

Build Status Version

Documentation

acpi is a Rust library for interacting with the Advanced Configuration and Power Interface, a complex framework for power management and device discovery and configuration. ACPI is used on modern x64, as well as some ARM and RISC-V platforms. An operating system needs to interact with ACPI to correctly set up a platform's interrupt controllers, perform power management, and fully support many other platform capabilities.

This crate provides a limited API that can be used without an allocator, for example for use from a bootloader. This API will allow you to search for the RSDP, enumerate over the available tables, and interact with the tables using their raw structures. All other functionality is behind an alloc feature (enabled by default) and requires an allocator.

With an allocator, this crate provides a richer higher-level interfaces to the static tables, as well as a dynamic interpreter for AML - the bytecode format encoded in the DSDT and SSDT tables.

See the library documentation for example usage. You will almost certainly need to read portions of the ACPI Specification too (however, be aware that firmware often ships with ACPI tables that are not spec-compliant).
