* [SCSI] qla2xxx: Support for asynchronous TM and Marker IOCBs.Madhuranath Iyengar2010-05-168-4/+366
| | | | | | | | | | | | | | Currently we can only issue the task management (TM) commands via the mailbox mechanism. This is a limitation, since only one mailbox command can be issued at a time. The purpose of this effort is to provide support for issuing and processing the respose to TM and Marker IOCBs asynchronously. Towards achieving this, the consolidated srb architecture that is currently used for BSG and IOCB/Logio commands has been enhanced and used.

* [SCSI] qla2xxx: Provide common framework for BSG and IOCB commands.Madhuranath Iyengar2010-05-167-142/+162
| | | | | | | | | | Currently, BSG and IOCB/Logio commands have a different framework (srb structs). The purpose of this effort is to consolidate them into a generalized framework for these as well as other asynchronous operations in the future.

* [SCSI] qla2xxx: Cleanup FCP-command-status processing debug statements.Andrew Vasquez2010-05-161-129/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Migrate to a consistent set of debug entries during status-IOCB handling: * group CS_TIMEOUT handling with CS_PORT_UNAVAILABLE and the like (more regrouping of common behaviour). * drop CS_DATA_OVERRUN handling as it now falls into the 'default' case (still returns DID_ERROR). * consolidate CS_RESET and CS_ABORTED handling, as we the only functional difference was a printk() (still returns DID_RESET). * dropped all the earlier inconsistent [qla_]printk()s sprinkled throught the needlessly large case-statement. Failure case I/Os are now logged with a 'standard' format: <command failure details> <command generic details> so, for example a dropped-frame is logged as: qla2xxx 0000:13:00.0: scsi(16:0:0) Dropped frame(s) detected (4000 of 4000 bytes). qla2xxx 0000:13:00.0: scsi(16:0:0) FCP command status: 0x15-0x18 (70018) \ oxid=78 ser=76 cdb=280000 len=4000 rsp_info=0 resid=0 fw_resid=4000 which should now convey all relevant information.

| | | | | | | | | | | | Currently error status is cleared only after the uncorrectable fatal errors in the qla2xxx_pci_slot_reset. This fix is added to clear the error status in qla2xxx_pci_resume.

* [SCSI] ibmvfc: Fix command completion handlingBrian King2010-05-021-0/+6
| | | | | | | | | | | | | | | Commands which are completed by the VIOS are placed on a CRQ in kernel memory for the ibmvfc driver to process. Each CRQ entry is 16 bytes. The ibmvfc driver reads the first 8 bytes to check if the entry is valid, then reads the next 8 bytes to get the handle, which is a pointer the completed command. This fixes an issue seen on Power 7 where the processor reordered the loads from memory, resulting in processing command completion with a stale handle. This could result in command timeouts, and also early completion of commands. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
