Information needed to debug driver problems and firmware faults is stored in the IOC’s MPT3SAS_ADAPTER data structure. Parameters such as IOCFacts, IOC flags (related to sge, MSI-X, error recovery etc.), performance mode type, TMs, internal commands reply status, etc. are present. For debugging purposes, it is therefore helpful to be able to capture this information so that the fault can be analyzed. Export the MPT3SAS_ADAPTER data structure in debugfs. The data is available in: /sys/kernel/debug/mpt3sas/scsi_hostX/ioc_dump Link: https://lore.kernel.org/r/1588056322-29227-1-git-send-email-suganath-prabu.subramani@broadcom.com Signed-off-by: Suganath Prabu <suganath-prabu.subramani@broadcom.com> Signed-off-by: Martin K.
