Re: Resources and ACPI

and when the device is kldload'ed you get :-

are these resources automagically allocated for me? Or do I have to
allocate them myself?

You have to allocate the resource.

Ok cool, but how do I get the resource list from acpi to allocated them then? Other than having an array of ioports and irqs, is there a way to get this information from acpi?

I've done an acpidump and indeed the are _CRS and _PRS ResourceTemplates that describe the io and irq requirements perfectly. How do I access this data? ACPI seems to have very little documentation and nothing else seems to get resource lists (except fdc_acpi.c and uart_bus_acpi.c which don't seem to be complete. ACPI_EVALUATE_OBJECT?!?)

Thanks,
Alan.
