This trivial module just binds the pci device on the host to a stub driver so that a real host driver can't bind to the device. It has no pci id table, it supports only dynamic ids. # echo "8086 10f5" > /sys/bus/pci/drivers/pci-stub/new_id # echo -n 0000:00:19.0 > /sys/bus/pci/drivers/e1000e/unbind # echo -n 0000:00:19.0 > /sys/bus/pci/drivers/pci-stub/bind # ls -l /sys/bus/pci/devices/0000:00:19.0/driver lrwxrwxrwx 1 root root 0 2008-11-25 19:10 /sys/bus/pci/devices/0000:00:19.0/driver -> ../../../bus/pci/drivers/pci-stub Cc: "Kay, Allen M" Cc: "Nakajima, Jun" Signed-off-by: Chris Wright Acked-by: Greg Kroah-Hartman Signed-off-by: Jesse Barnes --- Reading git-diff-tree failed
