/me looks a bit surprised.
This pretty much implies that any shpc bridge needs a second interface
to the hotplug functionality which can be driven via ACPI. Or the
firmware somehow handles this using smm (not sure this works for the IRQ
though).
Do you know how this is handled by real hardware?
cheers,
Gerd
