There are few special cases which needs to be handled deleting old port.
CASE1: In topology you need cascaded expanders. Through sysfs just make sure
topology is up. Erase the manufacturing image of the cascaded expander and
reset the board. In some cases Adapter will receive Exapnder Add event
before expander delete. In such a case, driver needs to delete duplicate
port before adding new port.
CASE2: Enable Device Missing delay of HBA through lsiutils. If expander or
end device is hotswapped with different device before DMD timer expires,
driver will get device add for new device first and then device deletion
event for the original devices will arrive later at DMD timer expires. In
this case also driver need to delete duplicate port before adding port for
new device.
Added new function which will make sure when new port is
added, that its not claiming the same phy resources already in use by
another port. If it does, then it will delete the other port before adding
the new port.

Removed all the mutex's for ioc->tm_cmds.mutex, then created one
single mutex inside the function mpt2sas_scsih_issue_tm. This is the
single function used when sending task management. Also the sanity
checks required for scsi mid layer escalation were moved to inside the
same function because these checks need to be done while the mutex is
held. The ioc->tm_cmds.mutex inside the IOCTL branch is really not
required since there is another mutex in this code called for ctl_cmds
handling this sync.

external host not connecting after controller reboot: The
problem is : devices are not coming back after having the cable
disconnected then reconnected. The problem is because the
driver/firmware device removal handshake is failing. Due to this failure,
the controller firmware is not sending out device add events when the target
is reconnected. This is root caused to a race in the driver/firmware device
removal algorithm. There is duplicate code in both interrupt and user
context; where target reset is being issue from user context path while
sas_iounit_control(OP_REMOVE) is being sent from interrupt context. An
active target_reset will fail the OP_REMOVE. To fix this problem, the
duplicate code has been removed from user context path.

Add the cancel_pending_work flag from the fw_event_work structure, and then to
set the flag during host reset, check the flag later from work threads
context and if cancel_pending_work_flag is set ingore those events.
Now Rescan after host reset is changed.
Added special task MPT2SAS_RESCAN_AFTER_HOST_RESET. This task will be queued
at the time of HBA reset. this task is treated as barrier. All work after
MPT2SAS_RESCAN_AFTER_HOST_RESET will be treated as new work and will be
server by callback handle. If host_recovery is going on while running RESCAN
task, it will wait for shos_recovery_done completion which will be called
from HBA reset DONE context.

Added new callbacks phy_enable and set_phy_speed in the
mpt2sas_transport_functions template. This will allow end user to
enable/disable phys and change links rates using the SysFS interface.
Current implementation only supports direct attached phys, but we
could in the future add support for expander based phys.
A new subroutine mpt2sas_config_set_sas_iounit_pg1 was added;
this wrapper function used to send request to controller firmware to modify
the phys and link rates. A new subroutine _transport_find_local_phy was added;
a function for easly obtaining the local phy object for direct attached.
Example to disable a phy
echo 0 > /sys/class/phy3:0/enable
Example to enable the same phy
echo 1 > /sys/class/phy3:0/enable
Example to change the link rate to 1.5
#echo "1.5 Gbit" > /sys/class/phy3:0/maximum_linkrate
#cat /sys/class/phy3:0/negotiated_linkrate
1.5 Gbit
Example to change the link rate to 3.0
#echo "3.0 Gbit" > /sys/class/phy3:0/maximum_linkrate
#cat /sys/class/phy3:0/negotiated_linkrate
3.0 Gbit
Example to change the link rate to 6.0
#echo "6.0 Gbit" > /sys/class/phy3:0/maximum_linkrate
#cat /sys/class/phy3:0/negotiated_linkrate
6.0 Gbit

Use resource_size_t to define the type resource for the system interface
register set.
The existing implementation was using "unsigned long" which would be 32 bit
in 32 bit OS. If 32 bit OS is using 64 bit physical
address space for the system interface register set, we need to shift to
using resource_size_t which takes care of physical address space.

shutdown
(1) Added new function _scsih_ir_shutdown. This function will issue the
MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED request via
MPI2_FUNCTION_RAID_ACTION. The function will wait 10 seconds for reply
message frame, then print out the ioc status and loginfo. This function is
only called when there are raid volumes present.
(2) Add shutdown callback in the struct pci_driver object scsih_driver. This
will be called only when the system is shutting down. From this function, we
will call _scsih_ir_shutdown mentioned above.
(3) Add support in _scsih_remove to call _scsih_ir_shutdown. The function
_scsih_remove will be called when the driver is unloaded (and system is
still running).
scsih internal command contex is added to send internal message frames
from mpt2sas_scsih.c.

Added command line option diag_buffer_enable. When the command line option is
set, the driver will automatically post diag buffers at driver load time.
The command line option diag_buffer_enable is bitwise, so it's possible to
enable both and/or snapshot + trace buffers. For trace, the driver will
allocate 1MB buffer, whereas for snapshot its 2MB. The purpose for this is
so the enduser doesn't have to manually use an application to setup diag
buffers for debugging firmware related issues.
Here is some examples
trace:
# insmod mpt2sas.ko diag_buffer_enable=1
snapshot:
# insmod mpt2sas.ko diag_buffer_enable=2
both trace and snapshot:
# insmod mpt2sas.ko diag_buffer_enable=3

Added command line option and shost sysfs attribute called
mpt2sas_fwfault_debug. When enduser writes a "1" to this parameter, this
will enable support in the driver for debugging firmware timeout related
issues. This handling was added in three areas (a) scsi error handling
callback called task_abort, (b) IOCTL interface, and (c) other timeouts that
result in diag resets, such as manufacturing config pages. When this
support is enabled, the driver will provide dump_stack to console, halt
controller firmware, and panic driver. The end user probably would want to
setup serial console redirection so the dump stack can be seen.
Here are the three methods for enable this support:
(a) # insmod mpt2sas.ko mpt2sas_fwfault_debug=1
(b) # echo 1 > /sys/module/mpt2sas/parameters/mpt2sas_fwfault_debug
(c) # echo 1 > /sys/class/scsi_host/host#/fwfault_debug (where # is
the host number)

The device driver was not handling updating device handles in all cases
across diag resets. To fix this issue, the driver is converted to using sas
address instead of handle as a lookup reference to the parent expander or
sas_host. Also, for both expanders and sas host, the phy handle will be one
unique handle. In the sas host case, the phy handle can be different for
every phy, so the change is to set the handle to the handle of the first
phy; every phy will be one single sas address(phy 0) instead of a different
sas address for every phy(previous implementation). So making one consistent
sas address for all the direct attachedports to the sas host, will make it
better user experience when using udev /dev/disk/by-path dev nodes

(1) Added three new functions to handle sending target resest and OP_REMOVE
from interrupt time, they are _scsih_tm_tr_send, _scsih_tm_tr_complete, and
_scsih_sas_control_complete. This code will create a link list of pending
target resets if there is no more available request in the hipriority
request queue. The list is stored in ioc->delayed_tr_list.
(2) All callback handler return type is changed from void to u8.
Now _base_interrupt will check for return type of callback handlers to
take decision of message frame is already freed or not.
In genral,
Return 1 meaning mf should be freed from _base_interrupt
0 means the mf is freed from function.

support multiple TM
1) create a pool of high priority message frames in the region of memory
between message frames and chains. The modifications are in
_base_allocate_memory_pools. Also create a seperate pool of memory for
internal commands located near the same region of memory. The pool of high
priority message frames is restriced by the facts->HighPriorityCredit.
2) Create additional API for accessing request message frames. New function
mpt2sas_base_get_smid_hpr is for highpriority request. New function
mpt2sas_base_get_smid_scsiio for SCSI_IO, passing in the scsi command
pointer. The mpt2sas_base_get_smid function is for requesting internal
commands.
3) Added new function _base_get_cb_idx to obtain the callback
index from one of the three pools of request message frames.
4) Removed wrapper functions _scsih_scsi_lookup_set and
_scsih_scsi_lookup_getclear. These were removed because this handling was
moved into mpt2sas_base_get_smid_scsiio and mpt2sas_base_free_smid.
5) The function mpt2sas_base_free_smid is modified so the request message
frames are put back on one of the three pools of request message frames.

This patch modifies the slave_configure callback so the messages that get sent
to system log for RAID1E volumes contain the string "RAID10" instead of
"RAID1E". These messages contain information regarding what kind of scsi device
is being added. Certain OEMS can enable displaying the RAID10 string instead of
RAID1E via manufacturing page 10. The driver will read this config page at
driver load time, then determine from the GenericFlags0 bits whether display
the RAID10 or RAID1E string, also even drive count is taken into consideration.

Changing SDEV Running state from interrupt context. Previously It was
handle in work queue thread. With this change It will not wait for work
queue thread to execute scsih_ublock_io_device to put SDEV into Running

This patch renames the flag for indicating host reset from
ioc_reset_in_progress to shost_recovery. It also removes the spin locks
surrounding the setting of this flag, which are unnecessary. Sanity checks on
the shost_recovery flag were added thru out the code so as to prevent sending
firmware commands during host reset. Also, the setting of the shost state to
SHOST_RECOVERY was removed to prevent deadlocks, this is actually better
handled by the shost_recovery flag.

Following host reset its possible that the controller firmware could
assign new handles for devices, as well as adding or deleting devices. There is
code in the driver that will rescan the topology folowing host reset; updating
device handles, and remove devices that are no longer responding. This patch
will improve the responsivness by moving this rescaning from the delayed hotplug
worker thread to immediately following the host reset.
