drv-acpi

drv-acpi is the ACPI platform discovery daemon in EriX hardware mediation.

It discovers a deterministic set of ACPI platform classes and reports them to deviced using typed IPC contracts.

Responsibilities

  • read ACPI bootstrap ingress through kernel-control operations:
    • IPC_KERNEL_CONTROL_OP_GET_ACPI_RSDP (20)
    • IPC_KERNEL_CONTROL_OP_READ_ACPI_QWORDS (21)
  • classify and normalize platform classes:
    • battery
    • AC adapter
    • TPM
    • thermal
  • map classes to seeded synthetic device IDs defined in lib-device
  • report discovery metadata to deviced via IPC_PHASE2_DEVICED_OP_REPORT_DEVICE
  • serve typed discovery RPCs:
    • IPC_PHASE2_DRV_ACPI_OP_DISCOVER (0x590)
    • IPC_PHASE2_DRV_ACPI_OP_READ_LAST_SCAN (0x591)

Non-Responsibilities

  • it does not own driver lifecycle policy (deviced owns start/stop/restart)
  • it does not implement full platform-specific ACPI table walking in v1
  • it does not manage dynamic hotplug policy

Build

cargo build --release --target x86_64-unknown-none \
  --features drv-acpi-integration-smoke,drv-acpi-integration-phase2-acpi

Test

cargo fmt --all -- --check
cargo clippy --all-targets --all-features -- -D warnings

VM/system validation is executed through the integration repository scenarios.
