IMO this is a bug. The patch enables the ACPI PCI interrupt every time
it is asserted. If this is really needed, this implies that the guest
OS detects some sort of inconsistency and keeps turning the ACPI
interrupt off.
The bug should be addressed instead of worked-around in this way.

Igor, could you clarify what happens there?

[Igor Lvovsky] Yes sure. I rechecked it and it seems like reasonable conclusion.
As I mentioned before, enable bit of PIRQRCA should be 0, but somehow
Windows set it all the time. One of the reasons can be some sort
of inconsistency.
My last patch can be temporary workaround and now we can get the ACPI
interrupts without disrupt anything else, but I'll try to find full solution for this issue.

Interestingly, Linux doesn't receive any interrupts from ACPI, too.
There must be something wrong with the hardware emulation.
At [1] you can find a question I sent to this list, but didn't get a
response. Just yesterday I started working on it again and it still
doesn't work, even with your patch. Before I start going through all the
ACPI specs and the Linux driver's code, do you have an idea what might
be the problem?
Thanks,
Michael

[Igor Lvovsky] Probably, I will go over the spec again.

[Igor Lvovsky] My patch fixes it for windows guest. I tried it for LID open/close events on my laptop. According to the spec OS should care these events through ACPI.
Now I have it works on windows guests via ACPI events, but on Linux guest it
work without ACPI (weird).

[Igor Lvovsky] Not yet, but I'll inform you if I'll find something
