Hi,
I observed that the PCI Bus id's of the onboard network cards changed
after I added a PCIe Dual DVB-Card to my system.
The ID's changed from 02:00.0, 03:00.0 (see lspci_with_dvb.txt) to
03:00.0, 04:00.0 (see lspci_with_dvb.txt)
How is the ordering of PCI/PCIe devices determined in generally by the
linux PCI subsystem?
is the Bus ID for a specific PCI/PCIe Slot deterministic at every boot
if no hotplug (removing or adding PCI/PCie cards) is involved?
can I assume that the Bus ID's don't change if I don't add or remove any
PCI/PCie cards?
regards,
Andreas Besse
