From e62cca19a9bbfc72c62632d95a7c01cd6476708c Mon Sep 17 00:00:00 2001 From: "kashyap.desai@lsi.com" Date: Thu, 4 Aug 2011 16:42:15 +0530 Subject: [SCSI] mptfusion: Better handling of DEAD IOC PCI-E Link down error condition Find Non-Operation IOC and remove it from OS: Detecting dead(non-functional) ioc will be done reading doorbell register value from fault reset thread, which has been called from work thread context after each specific interval. If doorbell value is 0xFFFFFFFF, it will be considered as IOC is non-operational and marked as dead ioc. Once Dead IOC has been detected, it will be removed at pci layer using "pci_remove_bus_device" API.
