# D3 gate — test-driver-manager-hotplug.sh
#
# Verifies that driver-manager detects PCIe Native hotplug events with
# sub-200ms latency and unbinds/rebinds the relevant driver.
#
# Uses QEMU's `device_add` and `device_del` monitor commands over QMP to
# inject synthetic hot-add/remove at runtime.

echo "  2. Send 'device_add vfio-pci,...' over QMP after boot"
echo "  3. Poll /scheme/driver-manager:/bound until new driver name appears"
echo "  4. Assert poll latency < 200ms"
echo "  5. Send 'device_del' over QMP"
