Hi, I am trying to enable Intel 82599 10GbE SR-IOV VFs on FreeBSD 12-CURRENT, and after enabled, the SR-IOV VFs can be seen by pciconf(1), but can not be seen by lspci(1), which is installed from ports/sysutils/pciutils: # pciconf -l | tail -2 ixv0@pci0:1:0:128: class=0x020000 card=0x002a1fc1 chip=0x10ed8086 rev=0x01 hdr=0x00 ixv1@pci0:1:0:130: class=0x020000 card=0x002a1fc1 chip=0x10ed8086 rev=0x01 hdr=0x00
# lspci | grep 82599 01:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01) 01:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01) After some debugging, I found that it is because of ARI. After ARI is enabled, the slot number is always 0 and the function number can be range between 0 and 255 when reading from /dev/pci, and this breaks lspci(1). Is it a behavior by design or not?
