Hi, I'm looking for a way to refresh the pci device list. In Linux, we can remove a particular pci device, and then after preforming = a "rescan" the device will appear again. For example, disable/rescind PCI (such as VF) : echo 1 > /sys/bus/pci/devices/0001\:00\:02.0/remove # Get the device back echo 1 > /sys/bus/pci/rescan I'm looking for a similar way in FreeBSD. Does the FreeBSD support the hotp= lug of a PCI device? Thanks in advance! Thanks, Hongxiong
