Below is the lspci output when the cards are connected at booting. $ lspci ... 02:00.0 PCI bridge: PLX Technology, Inc.

With the above setup, If I hotplug card c1 and/or c2, will my driver probe get invoked. 2. I dont have to add any rules for in /etc/udev/rules.d/*.rules for my driver to work. 3. The standard hotplug controller driver would get the hotplug event from the switch and handle it. 4. The standard hotplug controller driver will be responsible for invoking .probe and .remove functions of my driver. --- Thanks Anand > Date: Fri, 9 Dec 2011 12:45:25 +0000 > From: mjg59@xxxxxxxxxxxxx > To: anand_dk@xxxxxxxxxxx > CC: bhelgaas@xxxxxxxxxx; greg@xxxxxxxxx; linux-pci@xxxxxxxxxxxxxxx; linux-kernel@xxxxxxxxxxxxxxx; linux-hotplug@xxxxxxxxxxxxxxx > Subject: Re: PCIe Hotplugging not working > > Do you have anything in /sys/class/pci/slots ?
