Most machiens I see today have almost no chance of having PCI devices
without shared IRQs. This probably means any implementation will only
work on a small set of machines with very specific setup in terms of
which PCI slots they install cards in, and only as long as you don't
allow any type of hotplugging of devices (or ever changing hardware at
all). May not be worth implementing if it has such a limited use case.
The MSI setup on the other hand does sound like it might have potential
for working in general.
Looking at two random servers here and a desktop, interrupts are
unshared except for usb. A laptop was not so lucky. So "no chance" is
a bit extreme.
I agree it's far from optimal, but it is less limited than you imply.
