In a nutshell: The implementation of dev_find_slot() traverses the linked list of all devices in the devicetree, regardless of the topology. Since PCI bus numbers are only assigned in early ramstage, this function is not a reliable API. Furthermore, referencing (dynamically) assigned PCI busses by

Hi Matt, thanks for bringing the topic up. Please also contact your Intel reps about this via commercial support channel as well. I believe Patrick G. once stated that he could act as a relay when it comes to disputes between commercial and community development 'strategies'. On Wed, Sep 25, 2019
