2006-05-19[SCSI] mptspi: reset handler shouldn't be called for other bus protocolsJames Bottomley
All registered reset callback handlers are called during reset processing. The mptspi modules has its own reset callback handler, just recently added for issuing domain validation after host reset. If either the mptsas or mptfc driver are loaded, this callback could be called. Thus resulting in domain validation being issued for sas or fibre end devices. Fix this by having mptbase.c check the bus type against the driver type and only call the reset handler if they match (or if it's a non-bus specific reset handler).

2006-05-10[SCSI] mptfc: race between mptfc_register_dev and mptfc_target_allocmdr@sgi.com
A race condition exists in mptfc between the thread registering a device with the fc transport and the scan work generated by the transport. This race existed prior to the application of the mptfc bug fix patch. mptfc_register_dev() calls fc_remote_port_add() with the FC_RPORT_ROLE_TARGET bit set in the rport ids passed to the function. Having this bit set causes fc_remote_port_add() to schedule a scan of the device. This scan can execute before mptfc_register_dev() can fill in the dd_data in the rport structure. When this happens, mptfc_target_alloc() will fail because dd_data is null. Attached is a patch which fixes the problem. The patch changes the rport ids passed to fc_remote_port_add() to not have the TARGET bit set. This prevents the scan from being scheduled. After mptfc_register_dev() fills in the rport dd_data field, fc_remote_port_rolechg() is called, changing the role of the rport to TARGET. Thus, the scan is scheduled after dd_data is filled in which prevents the failure in mptfc_target_alloc().

2006-04-25[SCSI] - fusion - mptfc bug fix's to prevent deadlock situationsMoore, Eric
mptbase.h bump version number to 3.03.09 remove unneeded flags define workq and remove old fc specific locks mptbase.c initialize new lock and don't initialize two removed locks mptscsih.c when firmware reports target is no longer there, return DID_REQUEUE for fc hosts so that i/o doesn't get killed until the transport has an opportunity to manage the loss via its dev loss timer when the "eh_abort" routine is called, check to see if the driver has the command or not before looking to see if a reset is pending. James Smart and I talked about this and believe that the API for this routine is: if driver doesn't have command, return SUCCESS. This change helps prevent a target from being taken offline. SUCCESS is returned because it's likely that the command completed after error recovery timed it out but before it could be aborted. provide a routine to queue work to newly created workq, and use it. remove "ioc" from mptscsih_abort() it was only used one time. the other references were via hd->ioc, so I just moved it.... net change in references to ioc via hd->ioc is zero move hd->resetPending test and hd->timeouts increment to after the test for whether the command to be aborted remains known to the driver Make certain that the workq exists before queuing work to it. mptfc.c no longer need to lock rport data structures as I was able to single thread the code! I fixed up the debug code to eliminate compilation messages due to type mismatch in the printk. Got rid of some no longer needed rport flags. Initialize and destroy the workq used for the rescan work. simplify the logic regarding the increment of fc_rescan_work_count. use post increment and test for zero vs. pre increment and test for one; eliminate work_count variable: queue_work can be called with the work_lock held as it doesn't sleep Signed-off-by: Michael Reed <mdr@sgi.com> Signed-off-by: Eric Moore <Eric.Moore@lsil.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-04-14[SCSI] mptfusion - fix panic in mptsas_slave_configureMoore, Eric
Driver panic when RAID logical volume was present when driver loaded, or when a RAID logical volume was created on the fly. This issue was created in due to recent scsi_transport_sas change, when sas_read_port_mode_page was added into the mptsas drivers slave_config entry point. This new API expects that all sdev's to be assocated to an rphy, however that is not the case for logical volumes, as they are created using scsi_add_device, instead of sas_rphy_add().

2006-03-14[SCSI] fusion - expander hotplug suport in mptsas moduleMoore, Eric
This adds support for hot adding and removing expanders, and its associated attached devices. When there is a change in topology, the fusion firmware sends the MPI_EVENT_SAS_DISCOVERY event to the driver. The driver will read firmware config pages to determine what changes took place, and refresh drivers view of the world stored in ioc->sas_topology. Here is the details of the action the driver does: (1) Expander Added : The mptsas_discovery_work workqueue is called. Config pages read, and ioc->sas_topology is refreshed. The sas_phy_add() is called for each phy of the expander. The expanders attached devices are added via sas_rphy_add(). Added end devices are handled within the MPT_ADD_DEVICE logic in mptsas_hotplug_work workqueue. (2) Expander Delete : The sas_rphy_delete() will be called for the top most compenent of the parent that the expander is attached to. The sas_rphy_delete call will delete all the children phys, rphys, and end devices. This is handled from mptsas_discovery_work workqueue.

2006-03-01[SCSI] mptspi: Add transport class Domain ValidationJames Bottomley
This is the first half of a patch to add the generic domain validation to mptspi. It also creates a secondary "virtual" channel for raid component devices since these are now exported with no_uld_attach. What Eric and I would have really liked is to export all physical components on channel 0 and all raid components on channel 1. Unfortunately, this would result in device renumbering on platforms with mixed RAID/Physical devices which was considered unacceptable for userland stability reasons. Still to be done is to plug back the extra parameter setting and DV pieces on reset and hotplug. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
