Currently the driver doesn't take into consideraion of possible sg chaining when it walks through the sg list. This is fixed by using the sg_next() which automatically handles the chaining case. Obosolete code is removed as a result of this change. Signed-off-by:

This patch (as1358) fixes a bug in the error pathway of scsi_target_add(). If registration fails, the target should not be reaped.

Current design of mptsas is as follow. MPTSAS will do probe() if pci id matches for available card in system, irrespective of mode of controller. If controller is I/T mode or I mode, things are fine. If controller is only in T mode, mptsas is not doing complete process of mptsas_probe(). It will only make sure IOC structure is created and IOC reference is available for mptstm driver. Now While removing module we should take care case of Target mode only mptsas. If we are removing IOC which is only in Target mode, We should only detach IOC instead of following rest of the cleanup process which is only required for T mode controller. Now For T mode controller, only part clean up is done instead of complete cleanup. mpt_detach will call early in case of Target mode only controller. Signed-off-by:

Behavior changes only for IOCTLs that time out. Current behavior of Bus Reset remains the same for RAID Passthru Timeouts Current behavior of Diagnostic reset for any other type of IOCTL remains the same CHANGE: For IOCTL SCSI IOs that timeout, a Target Reset TM is sent, instead of Bus Reset. All error handing from that point is the same as what the driver currently does, which is to say that if the Device Reset TM fails it escalates do diagnostic reset. Signed-off-by:

Message Unit Reset - instructs the IOC to reset the Reply Post and Free FIFO's. All the Message Frames on Reply Free FIFO are discarded. All posted buffers are freed, and event notification is turned off. IOC doesnt reply to any outstanding request. This will transfer IOC to READY state. Message unit ready is less expensive operations than Hard Reset. soft reset will not force Firmware to reload again, it only do clean up of Message units. mpt_Soft_Hard_ResetHandler will first try for Soft Reset,if it fails then go for big hammer reset which is Hard Reset.

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. Signed-off-by:

bug fix in the handling of the internal device reset event The reason code check in scsih_sas_device_status_change_event never evaluates as true for internal device reset, hence driver never quiesce s IO when firmware is sending a device reset. The fix is to change the evaluate to: if (event_data->ReasonCode != MPI2_EVENT_SAS_DEV_STAT_RC_INTERNAL_DEVICE_RESET && event_data->ReasonCode != MPI2_EVENT_SAS_DEV_STAT_RC_CMP_INTERNAL_DEV_RESET) return; Signed-off-by:

incorrect timestamp on 32 bit platforms: The upper 32 bit of the timestamp was getting truncated when converting seconds to milliseconds, which was due to the variable being long. To fix the problem, the variable needs to be u64. Also the microseconds conversion to milliseconds was incorrect; it should be divide by 1000 instead of divide by 8. Signed-off-by:
