2008-01-11[SCSI] qla2xxx: Properly handle Vport state-change-notifications.Shyam Sundar
Drivers do SCRs for each Vport. When something changes in the fabric, firmware generates one interrupt for each RSCN. Based on the current implementation, in each case, we make recursive calls to handle RSCN for physical and each subsequent virtual ports. The fix is to also take into consideration the vp_idx, which is set by the firmware to indicate the vport the RSCN was meant for.

system-error. Callers of qla2x00_async_event() already populate the mb[] array upon invocation, doing so via the appropriate mailbox register accessors. The stale codes removed are leftover-bits kept during the FWI2 transition. Though relatively benign, the extra-reads are not valid for FWI2 boards (ISP24xx and above) and peek into the incorrect regions of registers.

2008-01-11[SCSI] ibmvscsi: requeue while CRQ closedRobert Jennings
CRQ send errors that return with H_CLOSED should return with SCSI_MLQUEUE_HOST_BUSY until firmware alerts the client of a CRQ transport event. The transport event will either reinitialize and requeue the requests or fail and return IO with DID_ERROR. To avoid failing the eh_* functions while re-attaching to the server adapter this will retry for a period of time while ibmvscsi_send_srp_event returns SCSI_MLQUEUE_HOST_BUSY. In ibmvscsi_eh_abort_handler() the loop includes the search of the event list. The lock on the hostdata is dropped while waiting to try again after failing ibmvscsi_send_srp_event. The event could have been purged if a login was in progress when the function was called. In ibmvscsi_eh_device_reset_handler() the loop includes the call to get_event_struct() because a failing call to ibmvscsi_send_srp_event() will have freed the event struct.

2008-01-11[SCSI] move single_lun flag from scsi_device to scsi_targetTony Battersby
Some SCSI tape medium changers that need the BLIST_SINGLELUN flag have the medium changer at one LUN and the tape drive at a different LUN. The inquiry string of the tape drive may be different from that of the medium changer. In order for single_lun to be effective, every scsi_device under a given scsi_target must have it set. This means that there needs to be a blacklist entry for BOTH the medium changer AND the tape drive, which is impractical because some medium changers may be paired with a variety of different tape drive models. It makes more sense to put the single_lun flag in scsi_target instead of scsi_device, which causes every device at a given target ID to inherit the single_lun flag from one LUN. This makes it possible to blacklist just the medium changer and not the tape drive.

2008-01-11[SCSI] megaraid_sas: support for poll_mode_io (reduced interrupt)bo yang
Added module parameter "poll_mode_io" to support for "polling" (reduced interrupt operation). In this mode, IO completion interrupts are delayed. At the end of initiating IOs, the driver schedules for cmd completion if there are pending cmds. A timer-based interrupt has also been added to prevent IO completion from being delayed indefinitely in the case that no new IOs are initiated. Some formatting issues in resume, suspend comment block also corrected Signed-off-by: Bo Yang <bo.yang@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

max_sectors_per_req 1. Setting the max_sectors_per_req based on max SGL supported by the FW. Prior versions calculated this value from controller info's max_sectors_1, max_sectors_2. For certain controllers/FW, this was resulting in a value greater than max SGL supported by the FW. Now we take the min of max sgl from FW and max_sectors calculation. 2. Increased MFI_POLL_TIMEOUT_SECS to 60 seconds from 10. FW may take a max of 60 seconds to respond to the INIT cmd.

2008-01-11[SCSI] 3w-9xxx: fix abysmal write performance on some motherboardsTony Battersby
The 3ware 9500S-8 SATA RAID controller exhibits terrible write performance when PCI memory-write-and-invalidate is disabled. This is easy to demonstrate by replacing pci_try_set_mwi() in the patch below with pci_clear_mwi(). My benchmarks show the following: MWI disabled: 15 MB/s write, 330 MB/s read MWI enabled: 240 MB/s write, 330 MB/s read Most motherboards will enable MWI without the driver having to set it explicitly, so most people probably wouldn't encounter this problem. For the few motherboards that don't enable it, this patch could give a 16x performance improvement for writing. This issue does not seem to affect the 9550SX controller, but the patch doesn't hurt it either. I haven't tested any of the other 3ware controllers.

2008-01-11[SCSI] aacraid: forced reset overrideSalyzyn, Mark
Some of our vendors have requested that our adapters ignore the hardware reset attempts during recovery and have enforced this with changes in Adapter Firmware. Some of our customers have requested the option to be able to reset the adapter under adverse adapter failure, we even had a few defects reported here considering it a regression that the Adapter could not be reset. This patch addresses this dichotomy. The user can force the adapter to be reset if it supports the IOP_RESET_ALWAYS command, in cases where the adapter has been programmed to ignore the reset, by setting the aacraid.check_reset parameter to a value of -1. The driver will not reset an Adapter that does not support the reset command(s). This patch also fixes and cleans up some of the logic associated with resetting the adapter.

2008-01-11[SCSI] add DID_REQUEUE string to scsi_show_result host tableMike Christie
I was working on patches which add new transport error values, when I noticed that DID_REQUEUE was not in the hostbyte_table. I do not think there is any way to hit the code path where scsi_show_result is called and where you return DID_REQUEUE, because DID_REQUEUE causes scsi-ml to always requeue the command. However, for completeness and because I want to one day send a patch that tries to add new host bytes values, I am sending this patch.
