Currently hisi_hba.lock is locked to deliver and receive a command to/from any hw queue. This causes much contention at high data-rates. To boost performance, lock on a per queue basis for sending and receiving commands to/from hw. Certain critical regions still need to be locked in the delivery and completion stages with hisi_hba.lock. New element hisi_sas_device.dq is added to store the delivery queue for a device, so it does not need to be needlessly re-calculated for every task.

Currently hisi_sas_device.device_id is a u64. This can create a problem in selecting the queue for a device, in that this code does a 64b division on device id. For some 32b systems, 64b division is slow and the lib reference must be explicitly included. The device id does not need to be 64b in size, so, as a solution, just make as an int. Also, struct hisi_sas_device elements are re-ordered to improve packing efficiency. Signed-off-by: NJohn Garry <john.garry@huawei.com> Signed-off-by: NMartin K. Petersen <martin.petersen@oracle.com>

Administrator intervention is currently required to get good numbers when switching from running latency tests to IOPS tests. The configured interrupt coalescing values will greatly effect the results of these tests. Currently, the driver has a single coalescing value set by values of the module attribute. This patch changes the driver to support auto-configuration of the coalescing value based on the total number of outstanding IOs and average number of CQEs processed per interrupt for an EQ. Values are checked every 5 seconds. The driver defaults to the automatic selection. Automatic selection can be disabled by the new lpfc_auto_imax module_parameter. Older hardware can only change interrupt coalescing by mailbox command. Newer hardware supports change via a register. The patch support both.

vports cannot login to target. For vports, lpfc_nodelist is allocated for targets only on completion of GFF_ID command. Driver checks if lpfc_nodelist exists for target before sending GFF_ID. So, GFF_ID and PLOGI are not sent. As mentioned by the comment in lpfc_prep_node_fc4type() routine, do not send GFF_ID only if this NPortID is previously identified as FCP target. Send GFF_ID if it is a newly identified remote port from GID_FT response.

The nvmet driver was rejecting the initiator's PRLI because its reg_rpi for the PLOGI was still outstanding. The initiator would resend the PRLI without delay and get the same answer. The PRLI retries would exhaust causing the nvme initiator to set the nvmet ndlp to UNMAPPED. The driver's lpfc_els_retry handler did not have a policy for an LS_RJT with explanation CMD_IN_PROGRESS for PRLI or NVME_PRLI. This caused the delay to remain at 0 but retry set 1. Fix: When the ELS response is LS_RJT, TPC and the command was PRLI or NVME_PRLI, just set the delay to 1000 mS to get a 1 second delay on the PRLI retry. This was enough to allow the REG_RPI to complete at the target.

When unloading the driver, the NVMET driver would wait the full 30 seconds for its UNMAPPED initiator node to get removed before continuing with the unload process. NVMEI worked correctly. For each rport put into UNMAPPED or MAPPED state by NVMET, the driver puts a reference on the NDLP. The difference is that NVMEI has a unregister call for its rports and the extra reference is removed in the unregister process. For NVMET, the driver has to remove the reference explicitly when dropping out of UNMAPPED or MAPPED because there is no unregister call. Add a call to lpfc_nlp_put on the ndlp when NVMET and the old state was UNMAPPED or MAPPED.

As the devloss API was implemented in the nvmei driver, an evaluation of the nvme transport and the lpfc driver showed dual management of the rports. This creates a bug possibility when the thread count and SAN size increases. The nvmei driver code was based on a very early transport and was not revisited until the devloss API was introduced. Remove the listhead in the driver's rport data structure and the listhead in the driver's lport data structure. Remove all rport_list traversal. Convert the driver to use the nrport (nvme rport) pointer that is now NULL or nonNULL depending on a devloss action. Convert debugfs and nvme_info in sysfs to use the fc_nodes list in the vport.

Add nvme initiator devloss support The existing implementation was based on no devloss behavior in the transport (e.g. immediate teardown) so code didn't properly handle delayed nvme rport device unregister calls. In addition, the driver was not correctly cycling the rport port role for each register-unregister-reregister process. This patch does the following: Rework the code to properly handle rport device unregister calls and potential re-allocation of the remoteport structure if the port comes back in under dev_loss_tmo. Correct code that was incorrectly cycling the rport port role for each register-unregister-reregister process. Prep the code to enable calling the nvme_fc transport api to dynamically update dev_loss_tmo when the scsi sysfs interface changes it. Memset the rpinfo structure in the registration call to enforce "accept nvme transport defaults" in the registration call. Driver parameters do influence the dev_loss_tmo transport setting dynamically. Simplifies the register function: the driver was incorrectly searching its local rport list to determine resume or new semantics, which is not valid as the transport already handles this. The rport was resumed if the rport handed back matches the ndlp->nrport pointer. Otherwise, devloss fired and the ndlp's nrport is NULL.
