Firmware is able to handle Broadcast primitives, but upstream driver does not have support for broadcast primitive handling. Now this patch is mainly to support broadcast primitives. Signed-off-by:

1. Handle integrated Raid device(Add/Delete) and error condition and check related to Raid device. is_logical_volume will represent logical volume device. 2. Raid device dual port support is added. Main functions to support this feature are mpt_raid_phys_disk_get_num_paths and mpt_raid_phys_disk_pg1. Signed-off-by:

Resending patch considering Grants G's code review. Main goal to submit this patch is code cleaup. 1. Better driver debug prints and code indentation. 2. fault_reset_work_lock is not used anywhere. driver is using taskmgmt_lock instead of fault_reset_work_lock. 3. setting pci_set_drvdata properly. 4. Ingore config request when IOC is in reset state.( ioc_reset_in_progress is set). 5. Init/clear managment frame proprely.(INITIALIZE_MGMT_STATUS and CLEAR_MGMT_STATUS) Signed-off-by:

1.) SAS topology Rescan is added. If Firmware is doing Reset and we get Device add interrupt from Firmware, we will not receive it as part of Reset is going ON. After Reset we will do special Rescan of SAS topology. 2.) Driver version changed from 3.04.08 to 3.04.09. Added proper lock/unlock in mptsas_not_responding_devices() as per James' comment.

1) rewrite of ioctl_cmds internal generated function that issue commands to firmware, porting them to be single threaded using the generic MPT_MGMT struct. All wait Queues are replace by completion Queue. 2) added seperate callback handler for ioctl task managment (mptctl_taskmgmt_reply), to handle command that timeout 3) rewrite mptctl_bus_reset Signed-off-by:

1.) Added taskmgmt_quiesce_io flag in IOC and removed resetPending from _MPT_SCSI_HOST struct. 2.) Reset from Scsi mid layer and internal Reset are seperate context. Adding DeviceResetCtx for internal Device reset frame. mptsas_taskmgmt_complete is optimized as part of implementation. Signed-off-by:

1.) rewrite taskmanagement request and completion routines, making them single threaded and using the generic MPT_MGMT struct, deleting mptscsih_TMHandler, replacing with single request TM handler mptscsih_IssueTaskMgmt, and killing the watchdog timer functions. 2.) cleanup ioc_reset callback handlers, introducing wrappers for synchronizing error recovery (mpt_set_taskmgmt_in_progress_flag, mpt_clear_taskmgmt_in_progress_flag), as the fusion firmware only handles one task management request at a time Signed-off-by:

1) Previously we had mutliple #defines to use same values. Now those #defines are optimized. MPT_IOCTL_STATUS_* is removed and MPT_MGMT_STATUS_* are new #defines. 2.) config path is optimized. Instead of wait Queue and timer, using completion Q. 3.) mpt_timer_expired is not used. [jejb: elide patch to eliminate mpt_timer_expired] Signed-off-by:

The reason for this change is there is a data corruption when four different physical memory regions in the 36GB to 37GB region are accessed. This is only affecting 1078. The solution is we need to use different addressing when filling in the scatter gather table for the effected memory regions. So instead of snooping on all four different memory holes, we treat any physical addresses in the 36GB address with the same algorithm. The fix is explained below 1) Ensure that the message frames are NOT located in the trouble region. There is no remapping available for message frames, they must be allocated outside the problem region. 2) Ensure that Sense buffers are NOT in the trouble region. There is no remapping available. 3) Walk through the SGE entries and if any are inside the trouble region then they need to be remapped as discussed below. 1) Set the Local Address bit in the SGE Flags field. MPI_SGE_FLAGS_LOCAL_ADDRESS 2) Ensure we are using 64-bit SGEs 3) Set MSb (Bit 63) of the 64-bit address, this will indicate buffer location is Host Memory. Signed-off-by:

The CNIC driver controls BNX2 hardware rings and resources used by iSCSI. Most hardware resources for iSCSI are separate from those used for ethernet networking. iSCSI uses a separate MAC address and IP address. The CNIC driver creates a UIO interface to handle the non-offloaded packets such as ARP, etc in userspace. Signed-off-by:

Add support to ibmvscsi for the capabilities MAD. This command gets sent to the Virtual I/O server prior to login in order to communicate client capabilities. Additionally it returns information regarding capabilities that the server supports. The two main capabilities communicated in this MAD are related to partition migration and client reserve. Client reserve allows for SCSI-2 reservations to be sent to virtual disks which are backed by physical LUNs and will result in the reservation being sent to the physical LUN. Signed-off-by:

A new mode of error reporting, fast fail, has been added to the VIOS which allows failover to happen more quickly. If this new fast fail mode is enabled on the VIOS and the vSCSI client supports the mode, the VIOS will not return MEDIUM error on path failures, but rather return VIOSRP_ADAPTER_FAIL in the crq response, which ibmvscsi will translate to DID_ERROR. This new mode can be enabled for single path configurations as well, so it is the new default error reporting mode. A module parameter is provided to disable this new behavior on the off chance it causes a problem on some old VIOS version. Signed-off-by:

The ibmvscsi driver currently sends the SRP Login before sending the Adapter Info MAD, which can result in commands getting sent to the virtual adapter before we are ready for them. This results in a slight window where the target devices may not behave as expected. Change the order and close the window. Signed-off-by:
