| | | | | | | | | | | | | and ISP82XX. Allow for the capture of a firmware dump but have a sysfs node (allow_cna_fw_dump) to allow the feature to be enabled/disabled dynamically. The default is off.

* [SCSI] qla2xxx: Disable adapter when we encounter a PCI disconnect.Chad Dupuis2013-12-191-2/+16
| | | | | | | | | | | | | If we become disconnected from the PCI bus/PCIe fabric, there can be long delays in register reads which can cause erroneous decisions to be made and cause a soft lockup if a lock is held too long. As a preventative measure, check for a disconnection (register reads that return -1) and then disable the board if we find ourselves in this condition. For now, check in our interrupt handlers and the per adapter one second timer.

* [SCSI] qla2xxx: Fix for locking issue between driver ISR and mailbox routinesgurinder.shergill@hp.com2013-05-121-16/+10
| | | | | | | | | | | | | | | The driver uses ha->mbx_cmd_flags variable to pass information between its ISR and mailbox routines, however, it does so without the protection of any locks. Under certain conditions, this can lead to multiple mailbox command completions being signaled, which, in turn, leads to a false mailbox timeout error for the subsequently issued mailbox command. The issue occurs frequently but intermittenly with the Qlogic 8GFC mezz card during card initialization, resulting in card initialization failure.
