I'm looking for a way to refresh/re-enumerate the pci device list. In Linux, you can remove a particular pci device, and then after preforming a "rescan" the device will appear again. In Linux it is done by: echo 1 > /sys/bus/pci/devices/.../remove echo 1 > /sys/bus/pci/rescan I'm looking for a similar functionality in freeBSD. *What do I want to achieve?* I'm using freeBSD and my pcie device can be reset from the host. But when it boots again, it's uncommunicative, so I want to rescan the pci devices in order to initiate a new connection between the host and the device. Any idea would be appreciated, even if it takes some coding effort. Thanks!help
