pci initialization with acpi

Hi,

I'm wondering if it's possible to retrieve device id, vendor id, etc using purely acpi/acpica commands instead of manually reading the pci conf headers? (I couldn't find it when I was skimming through the acpi/acpica documentations).

Thanks!

ACPI requires that you have a driver to access any PCI configuration space, so if your goal is simply to read pci id's it's easier to go through your own driver.
