PCI IRQ checker: MSI-X capability detection, spurious IRQ accounting, interrupt affinity probe using redox-driver-sys IrqHandle IOMMU checker: vendor detection (AMD-Vi/Intel VT-d), control-scheme unit initialization probe, event drain probe, wire-format tests Unified harness: test-irq-runtime.sh (guest + QEMU modes) following Phase 1-5 pattern — exit-code-based, explicit binary checks Zero warnings, all tests pass.

# IRQ and low-level controller runtime validation — automated QEMU test harness.
|
|
#
|
|
# Boots a Red Bear OS image in QEMU, logs in, and runs all IRQ runtime check
|
|
# binaries to validate that each low-level controller surface is present and
|
|
# actually functional at runtime, not just installed.
|
|
#
|
|
# Modes:
|
|
# --guest Run inside a Red Bear OS guest
|
|
# --qemu [CONFIG] Boot CONFIG in QEMU and run the same checks automatically
|
|
#
|
|
# Exit codes:
|
|
# 0 — all checks passed
|
|
# 1 — one or more checks failed
|
|
# 2 — QEMU boot or login failure

Usage:

./local/scripts/test-irq-runtime.sh --guest
|
|
./local/scripts/test-irq-runtime.sh --qemu [redbear-full]
|
|
|
|
This script validates the IRQ and low-level controller runtime substrate by
|
|
running the guest-side check binaries and using their exit codes as the
|
|
authoritative pass/fail signal.
|
|
|
|
Guest mode runs inside a Red Bear OS instance.
|
|
QEMU mode boots an image and runs checks automatically.
|
|
|
|
Required binaries (must be in PATH inside the guest):
|
|
redbear-phase-pci-irq-check — PCI IRQ runtime reports, MSI/MSI-X capability, affinity, spurious IRQs
|
|
redbear-phase-iommu-check — IOMMU runtime self-test + scheme control probes
|
|
redbear-phase-dma-check — DMA buffer allocation/runtime proof
|
|
redbear-phase-ps2-check — PS/2 + serio runtime proof
|
|
redbear-phase-timer-check — monotonic timer runtime proof
