* Added support for translating the SGLs associated with incoming
commands either to IEE SGL or NVMe PRPs for NVMe devices.

* The hardware translation of IEEE SGL to NVMe PRPs has limitations
and if a command cannot be translated by hardware then it will go to
firmware and the firmware needs to translate it. This will have a
performance impact. To avoid that, the driver proactively checks
whether the translation will be done in hardware or not. If not, then
driver translates.

1) Added support for probing pcie device and adding NVMe drives to SML
and driver's internal list pcie_device_list.

2) Added support for determing NVMe as boot device.

3) Added nvme device support for call back functions scan_finished
target_alloc,slave_alloc,target destroy and slave destroy.

 a) During scan, pcie devices are probed and added to SML to drivers
internal list.

 b) target_alloc & slave alloc API's allocates resources for
(MPT3SAS_TARGET & MPT3SAS_DEVICE) private datas and holds information
like handle, target_id etc.

 c) slave_destroy & target_destroy are called when driver unregisters
or removes device. Also frees allocated resources and info.

Kees Cook e4dca7b7aa treewide: Fix function prototypes for module_param_call()
Several function prototypes for the set/get functions defined by

following semantic patch:

more time and hence I/Os were failing.

Bart Van Assche 8893cf6cb1 scsi: mpt3sas: Avoid sleeping in interrupt context
Commit 669f044170 ("scsi: srp_transport: Move queuecommand() wait code
to SCSI core") can make scsi_internal_device_block() sleep.  However,
the mpt3sas driver can call this function from an interrupt
handler. Hence add a second argument to scsi_internal_device_block()
that restores the old behavior of this function for the mpt3sas handler.

The call chain that triggered an "IRQ handler enabled interrupts"
complaint is as follows:

_base_interrupt()
-> _base_async_event()
   -> mpt3sas_scsih_event_callback()
      -> _scsih_check_topo_delete_events()
         -> _scsih_block_io_to_children_attached_directly()
            -> _scsih_block_io_device()
               -> _scsih_internal_device_block()

logical block size units (e.g. REQ_OP_ZONE_REPORT and its 64B aligned
partial replies). In this case, forcing alignment of resid to the device
logical block size can break the command result, e.g. in the case of
REQ_OP_ZONE_REPORT, the exact number of zone reported by the device.

Move the partial completion alignement check of mpt3sas to a generic
implementation in sd_done(). The check is added within the default
section of the initial req_op() switch case so that the report and reset
zone commands are ignored. In addition, as sd_done() is not called for
passthrough requests, resid corrections are not done as intended by the
initial mpt3sas patch.

Ram Pai f2e767bb5d scsi: mpt3sas: Force request partial completion alignment
The firmware or device, possibly under a heavy I/O load, can return on a
partial unaligned boundary. Scsi-ml expects these requests to be
completed on an alignment boundary. Scsi-ml blindly requeues the I/O
without checking the alignment boundary of the I/O request for the
remaining bytes. This leads to errors, since devices cannot perform
non-aligned read/write operations.

This patch fixes the issue in the driver. It aligns unaligned
completions of FS requests, by truncating them to the nearest alignment
boundary.

James Bottomley ffb5845658 scsi: mpt3sas: fix hang on ata passthrough commands
mpt3sas has a firmware failure where it can only handle one pass through
ATA command at a time.  If another comes in, contrary to the SAT
standard, it will hang until the first one completes (causing long
commands like secure erase to timeout).  The original fix was to block
the device when an ATA command came in, but this caused a regression
with

So fix the original fix of the secure erase timeout by properly
returning SAM_STAT_BUSY like the SAT recommends.  The original patch
also had a concurrency problem since scsih_qcmd is lockless at that
point (this is fixed by using atomic bitops to set and test the flag).

Suganath Prabu S 7ff723ad0f scsi: mpt3sas: Unblock device after controller reset
While issuing any ATA passthrough command to firmware the driver will
block the device. But it will unblock the device only if the I/O
completes through the ISR path. If a controller reset occurs before
command completion the device will remain in blocked state.

Make sure we unblock the device following a controller reset if an ATA
passthrough command was queued.

This is a work around for a bug with LSI Fusion MPT SAS2 when perfoming
secure erase. Due to the very long time the operation takes, commands
issued during the erase will time out and will trigger execution of the
abort hook. Even though the abort hook is called for the specific
command which timed out, this leads to entire device halt
(scsi_state terminated) and premature termination of the secure erase.

Set device state to busy while ATA passthrough commands are in progress.

That check should be for the line sas_target_priv_data->raid_device =
raid_device;

Due to above hunk, we are not initializing raid_device's starget for
raid volumes, and so during raid disk deletion driver is not calling
scsi_remove_target() API as driver observes starget field of
raid_device's structure as NULL.

messages. This unfortunately is the wrong way around.

Note, the actual bug is older than af0094115 but this commit removed the
CONFIG_SCSI_MPT3SAS_LOGGING Kconfig option which hid the bug.

Calvin Owens 8bbb1cf63f mpt3sas: Fix warnings exposed by W=1
Trivial non-functional changes for a couple annoying things:

  1) Functions local to files are not declared static, which is
  frustrating when reading the code because it's non-obvious at first
  glance what's actually called from other files.

  2) Set-but-unused variables abound, presumably to mask -Wunused-result
  errors in the past. None of these are flagged today though (with one
  exception noted below), so remove them.

Fixing (2) exposed the fact that we improperly ignore the return value
of scsi_device_reprobe() in _scsih_reprobe_lun(). Fixing the calling
code to deal with the potential error is non-trivial, so for now just
WARN().

Calvin Owens 98c56ad32c mpt3sas: Eliminate dead sleep_flag code
With the exception of a single call to wait_for_doorbell_int(), all this
conditional sleeping code is dead. So delete it.
