2006-03-06[PATCH] lpfc 8.1.3: Protect NPL lists with host lockJamie Wellnitz
Protect NPL lists with host lock Symptoms: lpfc_findnode_rpi and lpfc_findnode_did can be called outside of the discovery thread context. We have to iterate through the NPL lists under the host lock and all add/del operations on those lists have to be done under host lock.

2006-03-06[PATCH] lpfc 8.1.3: Fix deadlock in lpfc_fdmi_tmo_handlerJamie Wellnitz
Fix deadlock in lpfc_fdmi_tmo_handler lpfc_fdmi_tmo_handler was calling lpfc_fdmi_cmd with the host_lock held. lpfc_fdmi_cmd assumes the host_lock is released as it calls functions that acquire the host_lock. lpfc_fdmi_tmo_handler acquired the host_lock to protect access to work_hba_events. This was already checked in the worker thread so we can remove that code completely and remove access to the host_lock.

2006-03-06[PATCH] lpfc 8.1.3: Fix performance when using multiple SLI ringsJamie Wellnitz
Fix performance when using multiple SLI rings Currently the driver allocates all of its SLI command and response ring entries to one primary ring. Other rings get little, or no, resources.

pci_read_config_byte() macro PCI hrd_type should be obtained with pci_read_config_byte() macro Driver keys off of this field to report the proper adapter type. The pci subsystem explicitly clears the multiport bit in the copy of the field given the driver. Thus, to properly name the card, obtain it from config space.

2006-03-06[PATCH] convert aic94xx over to using the sas transport end deviceJames Bottomley
Begin introducing the concept of sas remote devices that have an rphy embedded. The first one (this) is a simple end device. All that an end device really does is have port mode page parameters contained. The next and more complex piece will be expander remote devices.

2006-03-03[SCSI] make some sas class properties optionalJames Bottomley
aic94xx doesn't have a use for the bay or enclosure identifiers. Also, I think it's not going to need a get_linkerrors(), so wire up all of these exported properties as conditional on the underlying function support. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

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>

2006-02-27[SCSI] fix scsi process problems and clean up the target reap issuesJames Bottomley
In order to use the new execute_in_process_context() API, you have to provide it with the work storage, which I do in SCSI in scsi_device and scsi_target, but which also means that we can no longer queue up the target reaps, so instead I moved the target to a state model which allows target_alloc to detect if we've received a dying target and wait for it to be gone. Hopefully, this should also solve the target namespace race. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-02-27[SCSI] add execute_in_process_context() APIJames Bottomley
We have several points in the SCSI stack (primarily for our device functions) where we need to guarantee process context, but (given the place where the last reference was released) we cannot guarantee this. This API gets around the issue by executing the function directly if the caller has process context, but scheduling a workqueue to execute in process context if the caller doesn't have it.

2006-02-27[SCSI] don't call ips_eh_reset in ips_queue to avoid deadlockMike Christie
When the locking was changed in the eh code ips_eh_reset was changed so that it was a wraper around __ips_eh_reset and all ips_eh_reset does is grab the host lock and then calls __ips_eh_reset. In the queuecommand, ips_queue is called with the host_lock held so if it calls ips_eh_reset we will have a problem. This patch just has ips_queue call __ips_eh_reset. Patch is only compile tested.

2006-02-27[SCSI] Recognize missing LUNs for non-standard devicesAlan Stern
