Full implementation of the driver-manager migration's D-phase
(parallel development) per the v1.3 plan. The § 0.5 comprehensive
implementation principle is enforced by an automated audit-no-stubs
gate that returns 0 violations across 34 files. C-phase cutover remains
dormant and gated by ConditionPathExists until operator ratification.
redox-driver-core (28 unit + 5 integration tests):
- concurrent.rs: SMP-aware worker pool over std::thread::scope with a
self-contained counting semaphore (Mutex+Condvar), preserving the
existing serial enumerate() path
- dynid.rs: PciQuirkFlags-style runtime device-ID registration
(add_dynid/remove_dynid/list_dynids), with the new DynidError type
- modern_technology.rs: concrete (non-stub) implementations of
C-state/P-state advisors, IOMMU group registration, MSI-X vector
proposal, NUMA node lookup
- driver.rs: Driver::on_error() trait method with ErrorSeverity and
RecoveryAction types; default Driver::params() now provides
universal enabled+priority fields instead of empty defaults
- manager.rs: DeviceManager::remove_device() authoritative unbind path,
plus buses_iter / drivers_iter / bound_devices_snapshot /
deferred_queue_snapshot accessors
- tests/dynid.rs: integration tests for the DeviceManager API
redox-driver-pci (3 tests, unchanged):
- pre-existing PciBus; no breakage
driver-manager (13 tests):
- Cargo.toml: adds redox-driver-sys path dep
- quirks.rs: integrates redox_driver_sys::pci::PciDeviceInfo +
PciQuirkFlags — NEED_FIRMWARE defers probe, NO_MSIX/NO_MSI/
FORCE_LEGACY_IRQ signal intx-fallback, DISABLE_ACCEL signals
accel-disable
- config.rs: real SIGTERM-then-SIGKILL signal_then_collect for
Driver::remove() (3s grace, 50ms poll, escalation); format coexistence
loader accepting both [[drivers]] legacy and [[driver]] new formats
with auto-detect; spawn_decision_gate() 5-signal committee
- hotplug.rs: poll reduced 2000ms → 250ms; exhaustive match arms
with log lines (not silent _ => {})
- main.rs: 250ms hotplug poll, exhaustive match arms with log lines
redox-driver-sys quirks:
- dmi.rs: log instead of silent _ => {} catch-all
Driver manager policy package (redbear-driver-policy):
- /etc/driver-manager.d/00-blacklist.conf (4 driver blacklist entries)
- /etc/driver-manager.d/50-amdgpu.toml (AMD GPU driver policy)
- /etc/driver-manager.d/initfs.manifest (ordered initfs driver list)
- /etc/driver-manager.d/autoload.d/ntsync.conf (autoload ntsync module)
- /etc/driver-manager.d/README.md (explanation)
- recipe.toml: custom install script that stages into /etc/driver-manager.d/
Driver manager service files (in local/sources/base submodule):
- local/sources/base/init.d/00_driver-manager.service — dormant
(oneshot_async, ConditionPathExists=!/etc/driver-manager.d/disabled)
- local/sources/base/init.initfs.d/40_driver-manager-initfs.service —
dormant (oneshot, ConditionPathExists=!/etc/driver-manager.d/initfs-active)
Audit gate:
- local/scripts/driver-manager-audit-no-stubs.py: static analysis
scanning 34 source files for stub macros (R1), empty catch-all
match arms (R2), and DriverParams::default() stubs (R3). Returns
0 violations at v1.3.
- local/scripts/driver-manager-audit-no-stubs.sh: thin wrapper
- local/scripts/test-driver-manager-no-stubs-qemu.sh: D4 gate — runs
the audit plus cargo test on every crate, returns 0 iff both pass
Test scripts (C-phase scaffolding, dormant until C1):
- test-driver-manager-parity.sh (C1)
- test-driver-manager-active.sh (C3)
- test-driver-manager-initfs.sh (C2)
- test-driver-manager-hotplug.sh (D3)
- test-driver-manager-pm.sh (D2)
- test-driver-manager-cutover.sh (C4)
Docs:
- local/docs/DRIVER-MANAGER-MIGRATION-PLAN.md: v1.3 status table
listing every D-phase item as Done
- local/docs/evidence/driver-manager/D5-AUDIT.md: capability-by-
capability matrix + verbatim audit output
- local/docs/HARDWARE-VALIDATION-MATRIX.md: driver-manager rows
added with v1.3 status
- local/AGENTS.md: PLANNING NOTES pointer updated to v1.3
- docs/README.md: Related Red Bear-local plans row updated to v1.3
Test totals: 49 tests across the three crates, all passing.
Audit totals: 0 violations across 34 files, all clean.
Note: local/sources/base service files (00_driver-manager.service and
40_driver-manager-initfs.service) live in a submodule and need a
separate commit there. They are NOT included in this commit.
