I'm using 2.6 Kernel. I'm having a (Hot-pluggable) Qlogic HBA plugged into a PCI Express Slot. I want to fake an hot-unplug event for this HBA, without physically removing it from the slot. Basically what I want is that while the HBA is still physically present at the slot, I want to fire a command / program that would fake the hot-unplug event for this slot, and thus will deregister the HBA from Linux. Ideally, I want to do this from userspace. But if it is not possible, then I can go for a kernel module as well. I think that this feature was made available by "Fake PCI Hot plug controller Driver", but I believe that can only be used if my system does not have REAL hot-plugging slots. Can "Fake PCI Hot-plug Controller Driver (fakephp.ko)" and "PCI Express Hot-plug Controller Driver (pciehp.ko)" Co-exist ??? (So that I can manually give fake unplug event and THEN remove the device; While hot-plugging, I want PCI Express HPC driver to take care of every thing) Is it possible to do what I am trying to do?
