Currently, the mpt3sas driver sets the default queue depth based on the
physical interface of the attached device:
- SAS : 254
- SATA: 32
- NVMe: 128
The IOC firmware provides a recommended queue depth for each device through
SAS IO Unit Page1 for SAS/SATA and PCIe IO Unit Page 1 for NVMe devices.
If the host sets the queue depth greater than the firmware recommended
value, then the IOC places the I/Os above the recommended queue depth in an
internal pending queue. This consumes outstanding host-credit/resources,
thereby leading to potential starvation of other devices.
To avoid this, use the device depth recommended by the IOC firmware.

During first half of IOC initialization (i.e. before going for device

initialization operation.
Modify the driver to issue a diag reset operation to recover IOC from fault

The user can set trigger values in order to collect the IOC's host trace
buffer automatically upon detecting certain conditions. However, the
trigger values that the user sets are not persistent across system reboot
or reload of the driver.
In order to make the user trigger settings persistent, these trigger values
need to be saved in the IOC's NVRAM pages:
- Driver Persistent Trigger Page 0:
This page is used to store list of trigger types that are enabled
- Driver Persistent Trigger Page 1:
This page stores the list of Master triggers that are enabled
- Driver Persistent Trigger Page 2:
This page stores the list of MPI Event Triggers that are enabled
- Driver Persistent Trigger Page 3:
This page stores the list of SCSI Sense Triggers that are enabled
- Driver Persistent Trigger Page 4:
This page stores the list of IOCStatus-LogInfo Triggers that are
enabled.
Whenever user configures triggers, the driver persists the values in the
corresponding trigger pages. When the driver is subsequently reloaded, the
driver reads the values from the trigger pages and configures the triggers
accordingly.
During firmware upload operation, if the newer firmware supports the
trigger page feature, then driver persists the configured diag trigger
values to NVRAM.

Currently config_cmds.reply buffer is not memset to zero before posting
config page request message. In some cases, for the current config
request, the previous config reply is getting processed and we will observe
PageType mismatch between request to reply buffer. It will be difficult to
debug this type of issue and it confuses by thinking that HBA Firmware
itself posted the wrong config reply. So it is better to memset the
config_cmds.reply buffer with zeros before issuing the config request.

Enable interrupt coalescing only on high iops queues.
In ioc config page 1, offset 0x14 (ProductSpecific field) is used to
determine interrupt coalescing enabled/disabled on per reply descriptor
post queue group(8) basis. If 31st bit is zero, then interrupt coalescing
is enabled for all reply descriptor post queues. If 31st bit is set to one,
then user can enable/disable interrupt coalescing on per reply descriptor
post queue group(8) basis. So to enable interrupt coalescing only on first
reply descriptor post queue group (i.e. on high iops queues), set bit 0 and
31.
This configuration should reset during driver unload or shutdown to the
default settings. For this, the driver takes copy of default ioc page 1 and
copies back the default or unmodified ioc page1 during unload and
shutdown. This means that on next driver load (e.g. if older version driver
is loaded by user), current modified changes on ioc page1 won't take
effect.

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

Modified the mpt3sas driver to have a single driver module which
supports both SAS 2.0 & SAS 3.0 HBA devices.
* Added SAS 2.0 HBA device IDs to the mpt3sas_pci_table pci table.
* Created two separate SCSI host templates for SAS2 and SAS3 HBAs so
that, during the driver load time driver can use corresponding host
template(based the pci device ID) while registering a scsi host
adapter instance for that pci device.
* Registered two IOCTL devices, mpt2ctl is for SAS2 HBAs & mpt3ctl for
SAS3 HBAs. Also updated the code to make sure that mpt2ctl device
processes only those ioctl cmds issued for the SAS2 HBAs and mpt3ctl
device processes only those ioctl cmds issued for the SAS3 HBAs.
* Added separate indexing for SAS2 and SAS3 HBAs.
* Replaced compile time check 'MPT2SAS_SCSI' to run time check
'hba_mpi_version_belonged' whereever needed.
* Aliased this merged driver to mpt2sas using MODULE_ALIAS.
* Moved global varaible 'driver_name' to per adapter instance variable.
* Created two raid function template and used corresponding raid
function templates based on the run time check
'hba_mpi_version_belonged'.
* Moved mpt2sas_warpdrive.c file from mpt2sas to mpt3sas folder and
renamed it as mpt3sas_warpdrive.c.
* Also renamed the functions in mpt3sas_warpdrive.c file to follow
current driver function name convention.
* Updated the Makefile to build mpt3sas_warpdrive.o file for these
WarpDrive-specific functions.
* Also in function mpt3sas_setup_direct_io(), used sector_div() API
instead of division operator (which gives compilation errors on 32 bit
machines).
* Removed mpt2sas files, mpt2sas directory & mpt3sas_module.c file.
* Added module parameter 'hbas_to_enumerate' which permits using this
merged driver as a legacy mpt2sas driver or as a legacy mpt3sas
driver.
Here are the available options for this module parameter:
0 - Merged driver which enumerates both SAS 2.0 & SAS 3.0 HBAs
1 - Acts as legacy mpt2sas driver, which enumerates only SAS 2.0 HBAs
2 - Acts as legacy mpt3sas driver, which enumerates only SAS 3.0 HBAs
* Removed mpt2sas entries from SCSI's Kconfig and Makefile files.

When reading this adapter attribute, the driver will output the state of
GPIO[24]. It returns "0" if BMR is healthy and "1" for failure.
If it returns an empty string then it means that there was an error

As we are merging the both drivers we can no longer provide this
