If IOC Doorbell is 0xFFFFFFFF, it will be detected as non-operation/DEAD IOC. When a DEAD IOC is detected, the code is modified to remove that IOC and all its attached devices from OS. The PCI layer API pci_remove_bus_device() is called to remove the dead IOC. Signed-off-by: Nagalakshmi Nandigama Signed-off-by: James Bottomley --- Reading git-diff-tree failed
