@whitequark this is sadly normal, everything on bus ff: is Intel having engorged body parts for unnecessary PCI devices 

(To be fair, "look good" is not a criteria for PCI bus/interface design)

@equinox pretty sure it's a debug interface that's not meant to be exposed on motherboards shipped to customers

@whitequark @equinox Na this is just how they expose the uncore performance counters. Quite cool how much you can debug/ trace with those. https://builders.intel.com/docs/networkbuilders/4th-gen-intel-xeon-scalable-processor-xcc-codename-sapphire-rapids-uncore-performance-1746785301.pdf for example for a somewhat modern platform
