fusion: remove dead MTRR code If and when this gets enabled the driver could should split up IO memory space properly and that is quite a bit of work. Just remove the uncommented dead MTRR code then. There are a few motivations for this: a) Take advantage of PAT when available b) Help bury MTRR code away, MTRR is architecture specific and on x86 its replaced by PAT c) Help with the goal of eventually using _PAGE_CACHE_UC over _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit de33c442e titled "x86 PAT: fix performance drop for glx, use UC minus for ioremap(), ioremap_nocache() and pci_mmap_page_range()") Signed-off-by: Luis R.

[SCSI] mptfusion: Fix for device offline while doing aggressive HBA reset [Resend patch as per Bernd Schubert comment ] Issue: Device goes offline while doing aggressive HBA reset along with IO using some utility. Root cause: FW goes into bad state due to aggressive reset. Softreset does not help to recover FW. And also aggressive reset open up the window for Error handling thread to kicked off at the same time HBA will be in constant RESET loop as part of aggressive reset test case can lead Device to goes offline. Changes: 1. Added extra check as below inside eh_timed_out call back as below. if(ioc->ioc_reset_in_progress) Rc = EH_TIMER_RESET 2. Removed " DOORBELL_ACTIVE" check for SAS controller from task management context. Since SAS controller uses high priority queue for task management. This check is not required for SAS controller. 3.

[SCSI] mptfusion: Block Error handling for deleting devices or Device in DMD Issue description: In multipath topology, when device deletion is in transient state, multipath driver can call blk_flush_queue() as part of path failure. Before device get deleted from OS, Device may go OFFLINE as part of error handling kicked off triggered from multipathing driver. Above condition hits more frequently if device missing delay timer (which is LSI specific firmware parameter) is non zero value. root cause of this issue is Error handling thread is getting kicked off for device which is not really present(in transient state of deleting). This patch has solution for this issue. driver is now using eh_timed_out callback. See below. mptsas_transport_template->eh_timed_out = mptsas_eh_timed_out Using mptsas_eh_timed_out function, driver can decide weather vdevice is under Device missing delay or deleting state. for either of those cases, there is BLK_EH_RESET_TIMER return to scsi mid and error handling thread will not be kicked off for that particular scsi command.

[SCSI] mpt fusion: Fixing 1078 data corruption issue for 36GB memory region 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.

[SCSI] mptsas: do not use ioc->handle to locate hba portinfo structure While performing hardware raid reset testing via the raid's client, I noticed that sometimes, following the reset, that there would be more raid targets in the lsscsi output than there actually were raid targets. I tracked this down to the following issue. Fusion cannot always find the mptsas_portinfo structure for the hba because it uses the handle stored in ioc->handle to locate it. The problem is that the firmware can change the handle associated with the hba when h/w raid is reset (via the raid client). When this happens, the driver will allocate another mptsas_portinfo structure and link it into the chain of said structures. This ultimately causes confusion within the driver resulting in targets not being removed when they should be. Eric Moore pointed out that the hba's portinfo structure is always the first structure on the sas_topology list. This patch modifies mptsas.c to access the hba's portinfo structure by taking the first structure on said list.

[SCSI] mptsas: eliminate ghost devices One of the current problems the mptsas driver has is that of "ghost" devices (these are devices the firmware reports as existing, but what they actually represent are the parents of a lower device), so for example in my dual expander configuration, three expanders actually show up, two for the real expanders but a third is created because the firmware reports that the lower expander also has another expander connected (which is simply the port going back to the upper expander). The attached patch eliminates all these ghosts by not allocating any devices for them if the SAS address is the SAS address of the parent.

[SCSI] mptfc: fix fibre channel infinite request/response loop While doing board reset testing I was able to put the system in an infinite request/response loop between the scsi layer and mptscsih_qcmd() by aborting the reset. This patch installs a "SETUP RESET" handler which calls fc_remote_port_delete() for all registered rports. This blocks the target which prevents the loop. Additionally, should the reset fail to complete, the transport will now terminate i/o to the target.

[SCSI] mptfc: set fibre channel fw target missing timers to one second The fibre channel firmware provides a timer which is similar in purpose to the fibre channel transport's device loss timer. The effect of this timer is to extend the total time that a target will be missing beyond the value associated with the transport's timer. This patch changes the firmware timer to a default of one second which significantly reduces the lag between when a target goes missing and the notification of the fibre channel transport.

[SCSI] - fusion - mptfc bug fix's to prevent deadlock situations mptbase.h bump version number to 3.03.09 remove unneeded flags define workq and remove old fc specific locks mptbase.c initialize new lock and don't initialize two removed locks mptscsih.c when firmware reports target is no longer there, return DID_REQUEUE for fc hosts so that i/o doesn't get killed until the transport has an opportunity to manage the loss via its dev loss timer when the "eh_abort" routine is called, check to see if the driver has the command or not before looking to see if a reset is pending. James Smart and I talked about this and believe that the API for this routine is: if driver doesn't have command, return SUCCESS. This change helps prevent a target from being taken offline. SUCCESS is returned because it's likely that the command completed after error recovery timed it out but before it could be aborted. provide a routine to queue work to newly created workq, and use it. remove "ioc" from mptscsih_abort() it was only used one time. the other references were via hd->ioc, so I just moved it.... net change in references to ioc via hd->ioc is zero move hd->resetPending test and hd->timeouts increment to after the test for whether the command to be aborted remains known to the driver Make certain that the workq exists before queuing work to it. mptfc.c no longer need to lock rport data structures as I was able to single thread the code! I fixed up the debug code to eliminate compilation messages due to type mismatch in the printk. Got rid of some no longer needed rport flags. Initialize and destroy the workq used for the rescan work. simplify the logic regarding the increment of fc_rescan_work_count. use post increment and test for zero vs. pre increment and test for one; eliminate work_count variable: queue_work can be called with the work_lock held as it doesn't sleep Signed-off-by: Michael Reed <mdr@sgi.com> Signed-off-by: Eric Moore <Eric.Moore@lsil.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

[SCSI] fusion - expander hotplug suport in mptsas module This adds support for hot adding and removing expanders, and its associated attached devices. When there is a change in topology, the fusion firmware sends the MPI_EVENT_SAS_DISCOVERY event to the driver. The driver will read firmware config pages to determine what changes took place, and refresh drivers view of the world stored in ioc->sas_topology. Here is the details of the action the driver does: (1) Expander Added : The mptsas_discovery_work workqueue is called. Config pages read, and ioc->sas_topology is refreshed. The sas_phy_add() is called for each phy of the expander. The expanders attached devices are added via sas_rphy_add(). Added end devices are handled within the MPT_ADD_DEVICE logic in mptsas_hotplug_work workqueue. (2) Expander Delete : The sas_rphy_delete() will be called for the top most compenent of the parent that the expander is attached to. The sas_rphy_delete call will delete all the children phys, rphys, and end devices. This is handled from mptsas_discovery_work workqueue.

[SCSI] mptspi: Add transport class Domain Validation This is the first half of a patch to add the generic domain validation to mptspi. It also creates a secondary "virtual" channel for raid component devices since these are now exported with no_uld_attach. What Eric and I would have really liked is to export all physical components on channel 0 and all raid components on channel 1. Unfortunately, this would result in device renumbering on platforms with mixed RAID/Physical devices which was considered unacceptable for userland stability reasons. Still to be done is to plug back the extra parameter setting and DV pieces on reset and hotplug. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched.

[SCSI] fusion SAS support (mptsas driver) updates Summary of Changes: * splitting mpt_interrupt per Christophs suggestion about a month ago * rename ScsiCfgData to SpiCfgData structure, then move all the raid related info into new structure called RaidCfgData. This is done because SAS supports RAID, as well as SPI, so the raid stuff should be seperate. * incorrect timeout calculation for cntdn inside WaitForDoorbellAck and WaitForDoortbellInt * add support for interpreting SAS Log Info * Increase Event Log Size from 0xA to 0x32 * Fix bug in mptsas/mptfc/mptspi - when controller has Initiator Mode Disabled, and only running in TargetMode, the mptctl would panic when loading. The fix is to return 0, instead of -ENODEV, in SCSI LLD respective probe routines * Fix bug in mptlan.c - driver will panic if there is host reset, due to dev being set to zero in mpt_lan_ioc_reset * Fix's for SPI - Echo Buffer * Several fix's in mptscsih_io_done - FCP Response info, RESIDUAL_MISMATCH, Data Underrun, etc. * Cleanup Error Handling - EH handlers, mptscsih_flush_cmds, and zeroing out ScsiLookup from mptscsih_qcmd * Cleanup asyn event handling from mptscsih -> mptscsih_event_process. Also added support for SAS Persistent Table Full, an asyn event Signed-off-by: Eric Moore <Eric.Moore@lsil.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
