Daniel Samson d26262bf56 pci-bus registers and reports what it scans (M19.2) ... Each function is registered under the bridge with the config-space slice and BARs sized by the same all-ones probe the kernel uses — byte-for-byte equal descriptors, so the idempotent register returns the kernel's existing node ids during coexistence instead of duplicating the tree. The bridge gained the 16-bit io_port aperture that functions' I/O BARs need to pass containment. Reports carry the registered device_id, and the pci-scan scenario drills a forced restart: kill the enumerator after its reports, watch the respawn re-scan, and assert the broker's PCI node count never grew. The usb-restart test trigger is pinned to the xHCI reporter (pci-bus racing it to two reports used to steal the kill). Harness hardening: failing cases preserve their serial logs; the heavy scenarios run at 150s.		2026-07-13 02:22:19 +01:00
