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.

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.

Added logic to separate RQE buffers from IO op resources
(sgl/iocbq/context). During initialization, the driver will determine
how many SGLs it will allocate for NVMET (based on what the firmware

Now that hdr/data buffers are immediately reposted back to the RQ, 512
RQEs for each MRQ is sufficient. Also, since NVMET data buffers are now

BUG: unable to handle kernel NULL pointer dereference at 0000000000000018

Cause: As the initiator driver completes discovery at different stages,
it call lpfc_nvme_update_localport to hint that the DID and role may have
changed. In the implementation of lpfc_nvme_update_localport, the driver
was not validating the localport or the lport during the execution
of the update_localport routine. With the recent upstream additions to
the driver, the create_localport routine didn't run and so the localport
was NULL causing the page-fault Oops.
Fix: Add the CONFIG_LPFC_NVME_INITIATOR preprocessor inclusions to
lpfc_nvme_update_localport to turn off all routine processing when
the running kernel does not have NVME configured. Add NULL pointer
checks on the localport and lport in lpfc_nvme_update_localport and
dump messages if they are NULL and just exit.

Reviewing the result of what was just added for Kconfig, we made a poor
choice. It worked well for full kernel builds, but not so much for how
it would be deployed on a distro.
Here's the final result:
- lpfc will compile in NVME initiator and/or NVME target support based
on whether the kernel has the corresponding subsystem support.
Kconfig is not used to drive this specifically for lpfc.
- There is a module parameter, lpfc_enable_fc4_type, that indicates
whether the ports will do FCP-only or FCP & NVME (NVME-only not yet
possible due to dependency on fc transport). As FCP & NVME divvys up
exchange resources, and given NVME will not be often initially, the
default is changed to FCP only.

A previous change unilaterally removed the hba reset entry point
from the sli3 host template. This was done to allow tape devices
being used for back up from being removed. Why was this done ?
When there was non-responding device on the fabric, the error
escalation policy would escalate to the reset handler. When the
reset handler was called, it would reset the adapter, dropping
link, thus logging out and terminating all i/o's - on any target.
If there was a tape device on the same adapter that wasn't in
error, it would kill the tape i/o's, effectively killing the
tape device state. With the reset point removed, the adapter
reset avoided the fabric logout, allowing the other devices to
continue to operate unaffected. A hack - yes. Hint: we really
need a transport I_T nexus reset callback added to the eh process
(in between the SCSI target reset and hba reset points), so a
fc logout could occur to the one bad target only and stop the error
escalation process.
This patch commonizes the approach so it can be used for sli3 and sli4
adapters, but mandates the admin, via module parameter, specifically
identify which adapters the resets are to be removed for. Additionally,
bus_reset, which sends Target Reset TMFs to all targets, is also removed
from the template as it too has the same effect as the adapter reset.

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.

When building with -Wextra, we get a lot of warnings for the lpfc driver
concerning expressions that are always true, starting with:
drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_enable_npiv_init':
drivers/scsi/lpfc/lpfc_attr.c:2786:77: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_enable_rrq_init':
drivers/scsi/lpfc/lpfc_attr.c:2802:76: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_suppress_link_up_init':
drivers/scsi/lpfc/lpfc_attr.c:2812:2050: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
drivers/scsi/lpfc/lpfc_attr.c: In function 'lpfc_log_verbose_init':
drivers/scsi/lpfc/lpfc_attr.c:3064:1930: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
The code works as intended, but it would be nice to shut up the warning
so we don't clutter up build logs with this. Using a separate inline
function for it makes it clear to the compiler that the comparison is
necessary in the caller but still lets it do the constant-folding.
