2017-02-23scsi: lpfc: NVME Initiator: Base modificationsJames Smart1-380/+1023
NVME Initiator: Base modifications This patch adds base modifications for NVME initiator support. The base modifications consist of: - Formal split of SLI3 rings from SLI-4 WQs (sometimes referred to as rings as well) as implementation now widely varies between the two. - Addition of configuration modes: SCSI initiator only; NVME initiator only; NVME target only; and SCSI and NVME initiator. The configuration mode drives overall adapter configuration, offloads enabled, and resource splits. NVME support is only available on SLI-4 devices and newer fw. - Implements the following based on configuration mode: - Exchange resources are split by protocol; Obviously, if only 1 mode, then no split occurs. Default is 50/50. module attribute allows tuning. - Pools and config parameters are separated per-protocol - Each protocol has it's own set of queues, but share interrupt vectors. SCSI: SLI3 devices have few queues and the original style of queue allocation remains. SLI4 devices piggy back on an "io-channel" concept that eventually needs to merge with scsi-mq/blk-mq support (it is underway). For now, the paradigm continues as it existed prior. io channel allocates N msix and N WQs (N=4 default) and either round robins or uses cpu # modulo N for scheduling. A bunch of module parameters allow the configuration to be tuned. NVME (initiator): Allocates an msix per cpu (or whatever pci_alloc_irq_vectors gets) Allocates a WQ per cpu, and maps the WQs to msix on a WQ # modulo msix vector count basis. Module parameters exist to cap/control the config if desired. - Each protocol has its own buffer and dma pools. I apologize for the size of the patch.

2016-11-25scsi: lpfc: fix oops/BUG in lpfc_sli_ringtxcmpl_put()Mauricio Faria de Oliveira1-6/+8
The BUG_ON() recently introduced in lpfc_sli_ringtxcmpl_put() is hit in the lpfc_els_abort() > lpfc_sli_issue_abort_iotag() > lpfc_sli_abort_iotag_issue() function path [similar names], due to 'piocb->vport == NULL': BUG_ON(!piocb || !piocb->vport); This happens because lpfc_sli_abort_iotag_issue() doesn't set the 'abtsiocbp->vport' pointer -- but this is not the problem. Previously, lpfc_sli_ringtxcmpl_put() accessed 'piocb->vport' only if 'piocb->iocb.ulpCommand' is neither CMD_ABORT_XRI_CN nor CMD_CLOSE_XRI_CN, which are the only possible values for lpfc_sli_abort_iotag_issue(): lpfc_sli_ringtxcmpl_put(): if ((unlikely(pring->ringno == LPFC_ELS_RING)) && (piocb->iocb.ulpCommand != CMD_ABORT_XRI_CN) && (piocb->iocb.ulpCommand != CMD_CLOSE_XRI_CN) && (!(piocb->vport->load_flag & FC_UNLOADING))) lpfc_sli_abort_iotag_issue(): if (phba->link_state >= LPFC_LINK_UP) iabt->ulpCommand = CMD_ABORT_XRI_CN; else iabt->ulpCommand = CMD_CLOSE_XRI_CN; So, this function path would not have hit this possible NULL pointer dereference before. In order to fix this regression, move the second part of the BUG_ON() check prior to the pointer dereference that it does check for. For reference, this is the stack trace observed. The problem happened because an unsolicited event was received - a PLOGI was received after our PLOGI was issued but not yet complete, so the discovery state machine goes on to sw-abort our PLOGI. kernel BUG at drivers/scsi/lpfc/lpfc_sli.c:1326!

2015-06-13lpfc: Fix to drop PLOGIs from fabric node till LOGO processing completesJames Smart1-1/+1
The domain controller PLOGI's concurrent with prior LOGO's/unreg_rpi's completing created a race condition where driver rpi ref count can inadvertantly hit 0 and the rpi attempted to be freed. This error sometimes resulted in Warning messages indicating kref.h via lfpc_nlp_get+0x128. Correct by dropping any new PLOGI until the prior nport state has settled.

2015-06-13lpfc: Add support for using block multi-queueJames Smart1-51/+23
With blk-mq support in the mid-layer, lpfc can do IO steering based on the information in the request tag. This patch allows lpfc to use blk-mq if enabled. If not enabled, we fall back into the emulex-internal affinity mappings. This feature can be turned on via CONFIG_SCSI_MQ_DEFAULT or passing scsi_mod.use_blk_mq=Y as a parameter to the kernel.

2015-04-10lpfc: Fix premature release of rpi bit in bitmaskJames Smart1-3/+46
Currently, the driver plays off the fact that older sli4 adapters have a different rpi access pattern that allowed for the rpi reference to be released earlier in the teardown sequence, allowing the driver to recycle the rpi value sooner. Newer sli4 adapters have a different access pattern that requires us to wait for a later mailbox completion. This changes the put call location on the newer sli4 adapters. Symptoms of the error are "0110 ELS" and the "0372 iotag" errors.
