scsi: lpfc: NVME Initiator: Base modifications

2017-02-22T23:41:43Z

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.

scsi: lpfc: minor code cleanups

2017-02-22T23:41:42Z

This contains code cleanups that were in the prior patch set. This allows better review of real changes later. minor code cleanups: fix indentation, punctuation, line length addition/reduction of whitespace remove unneeded parens, braces lpfc_debugfs_nodelist_data: print as u64 rather than byte by byte covert printk(KERN_ERR to pr_err small print string deltas use num_present_cpus() rather than count them comment updates rctl/type names moved to module variable, not on stack Signed-off-by: Dick Kennedy Signed-off-by: James Smart Reviewed-by: Johannes Thumshirn Reviewed-by: Hannes Reinecke Signed-off-by: Martin K.

lpfc: Add support for using block multi-queue

2015-06-13T15:20:59Z

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.

[SCSI] lpfc 8.3.43: Fixed not processing task management IOCB response status

2013-10-25T08:58:18Z

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. Signed-off-by: James Smart Signed-off-by: James Bottomley
