2017-02-23scsi: lpfc: NVME Initiator: Base modificationsJames Smart1-0/+6
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.

2015-06-13lpfc: Add support for using block multi-queueJames Smart1-0/+3
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.

This patch implements the changes requested by Jeremy Linton: http://marc.info/?l=linux-scsi&m=136242124409687&w=2 The patch revises the command issuing behavior, detecting cases where the Task Mgmt command may have completed but with a non-successful status, which it previously treated as a successful TMF. The patch also corrects a flushing of I/O that was done which should only be done on successful TMF completion.

2007-06-18[SCSI] lpfc: NPIV: split portsJames Smart1-2/+1
The driver is reorganized to separate the handling of the adapter from the handling of the FC port. Adapter handling includes submissions of command requests, receiving responses, and managing adapter resources. The FC port includes the discovery engine, login handling, and the mapping of a Scsi_Host on the "port". Although not a large functional change, as it touches core structures and functions, resulting in a large text delta.
