I have a situation where I need to get an ACPI device. The PNP system
seems like the way to go for this, but I need some extra objects from
the ACPI namespace for this device (_IFT and _SRV to be specific,
supposidly added in ACPI 3.0). There doesn't seem to be a clean way to
do this right now. What would be the best way to get these?
Thanks,
-Corey

If your code knows about specific AML methods, then it is by-definition,
ACPI-aware, and can't be hidden (completely) behind PNP.
Either that, or some ACPI-aware code needs to exist to intervene to
allow your code to know know anything about ACPI.
So you could make it ACPI aware like 8250_acpi.c was, before it was
deleted...

True, but the PNP stuff does a lot of the work :)

I was thinking of some way to determine if it is ACPI and get the
handle, or a new call to get resources.

So just use ACPI directly. This will bypass the PNP port reservation
for that particular ACPI device, I assume.
