* lpfc: Add support for using block multi-queueJames Smart2015-06-131-1/+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.

* lpfc: Fix premature release of rpi bit in bitmaskJames Smart2015-04-101-2/+22
| | | | | | | | | | | | | | | | 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.

* lpfc: Fix host reset escalation killing all IOs.James Smart2015-04-101-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix host reset escalation killing all IOs. SLI-3 adapters will use a new host template. The template differs from SLI-4 adapters in that it does not have an eh_host_reset_handler. Lpfc has traditionally never had a host_reset. The host reset handler was added when we ran into a stuck hardware condition on a SLI-4 adapter. The host_reset will reset and reinit the pci function, clearing the hardware condition. Unfortunately, the host reset handler uses attach/detach code paths, which makes scsi_add_host() and scsi_remove_host() calls. Meaning, a host_reset will completely remove the scsi_host from the system. As a new call to scsi_add_host() is made, the shost# changes, which results in completely new scsi_devices and device names. All the older scsi devices on the old shost# are now orphaned and unrecoverable. We realize we need to re-implement the host_reset_handler so the scsi_host stays registered across the host_reset, but that will be a rather lengthy effort. In the short term, we had an immediate need to restore the SLI-3 devices to their working behavior, with the easiest path being to remove their host_reset handler.
