Why do you need that information?  What are the constraints in which
interrupt sharing would make a difference?

Also, go read about MSI/MSI-X, if you care about this stuff, you need to
know about message-signaled interrupts.

And SMI and SMM as well, ThinkPads likes to spend some time in
la-la-land quite ogten, and the OS only knows it happened because the
hardware timers advanced more than what it would expect while it was
frozen in a timestop and the CPU was in SMM running SMBIOS code.
