Hi Yinghai,
I used custom_method module to make root port device 0000:00:07.0 support acpi hotplug (by adding _EJ0 method),
This root port device also connected to a slot which support hotplug. I tested to hot plug root port device 0000:00:07.0,
and test steps and info as bellow, if there are somethings missing during test, please let me know.
Thanks very much!
