(1) for the MPI2_EVENT_IR_OPERATION_STATUS event, add support to print "background init" or "make data consistent" for debugging purposes. If the RAIDOperation is set to a value not defined, then don't print anything (2) for the MPI2_EVENT_SAS_DEVICE_STATUS_CHANGE event, add support to print "expander reduced functionality" and "expander reduced functionality complete", which are new events.

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) Signed-off-by: NKashyap Desai <kashyap.desai@lsi.com> Signed-off-by: NEric Moore <Eric.moore@lsi.com> Signed-off-by: NJames Bottomley <James.Bottomley@suse.de>

Add support in the driver to check for valid response info in the scsi state, then check to see if the response code is MPI2_SCSITASKMGMT_RSP_INVALID_FRAME; when this condition occurrs, the driver will return DID_SOFT_ERROR. A return code of DID_SOFT_ERROR will result in a retry at the scsi-mid layer level. An additional change added to obtain the response code from the 1st byte of the response info instead of last.

This handles the case where driver receives a expander removal event while it is in the middle of processing an expander add event. The existing implementation will stop processing futher device adds when a expander delete arrives on top of add expander add. Due to a sanity check in the driver, the devices there were not added, were never handshaked to firmware with the device removal handshake protocal. Since the driver didnt' do the handshake, the controller never provide further add events. To fix this issue, the sanity check was removed so the driver will always do the device removal handshake protocal.

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 Signed-off-by: NKashyap Desai <kashyap.desai@lsi.com> Signed-off-by: NEric Moore <Eric.moore@lsi.com> Signed-off-by: NJames Bottomley <James.Bottomley@suse.de>

(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.

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.

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.

When a volume is activated, the driver will recieve a pair of ir config change events to remove the foreign volume, then add the native. In the process of the removal event, the hidden raid componet is removed from the parent.When the disks is added back, the adding of the port fails becuase there is no instance of the device in its parent. To fix this issue, the driver needs to call mpt2sas_transport_update_links() prior to calling _scsih_add_device. In addition, we added sanity checks on volume add and removal to ignore events for foreign volumes.
