Hello, Is there a way in LB to hide a PCI device from the OS? I want to prevent linux from loading the device driver automatically for a particular PCI device. (Similar to a device behind a bridge). I don't want to do any tweaks in linux. I appreciate your time. -Baski

I have not tried this lately. But it used to be the case that if all the BARs were 0, Linux would assume the device was "not enabled".

OK, I may be out of date. Last time I tried to let the kernel do this it gave up, but that was a long time ago.
