ACPI based PCI/PCIe bridge hotplug

Hi all,

we had a discussion about ACPI hotplug today at work. Someone claimed that ACPI
would not support PCI/PCIe bridge hotplug.

I don't know much about ACPI, but that seemed like a surprising limitation
to me. After a little research, I found that the ACPI hotplug code seems to
support it, and Microsoft was talking about adding it to Vista back in 2003.

So ... just for my education, I have a couple of questions: Does ACPI support
PCI/PCIe bridge hotplug or not ? And if it does, are there any limitations ?

Thanks,
Guenter
