This is a comprehensive patch for FC-FC4 provider. tcm_fc is a FC-FC4 provider which glues target core (TCM) with Fiber channel library (libfc). tcm_fc uses existing FC4 provider hooks from Fiber channel library. This Fiber channel library is used by FCoE (transport - FC over Ethernet) protocol driver as well. Combination of modules such as Fiber channel library, tcm_fc, TCM target core, and FCoE protocol driver enables functional FCoE target. This patch includes initial commit for tcm_fc plus additional enhancement, bug fixes. This tcm_fc module essentially contains 3 entry points such as "prli", "prlo", "recv". When process login request (ELS_PRLI) request is received, Fiber channel library (libfc) module calls passive providers (FC-FC4, tcm_fc) (if any registered) "prli" function. Likewise when LOGO request is received, "prlo" function of passive provider is invoked by libfc. For all other request (e.g. any read/write, task management, LUN inquiry commands), "recv" function of passiver provider is invoked by libfc. Those passive providers "prli, prlo, recv" functions interact with TCM target core for requested operation. This module was primarily developed by "Joe Eykholt" and there were significant contributions from the people listed under signed-off.

On systems with very large numbers (> 1600 or so) of SCSI devices, cat /proc/scsi/scsi ends up failing with -ENOMEM. This is due to the show routine simply iterating over all of the devices with bus_for_each_dev(), and trying to dump all of them into the buffer at the same time. On my test system (using scsi_debug with 4064 devices), the output ends up being ~ 632k, far more than kmalloc will typically allow. This patch defines its own seq_file opreations to iterate over the scsi devices.The result is that each show() operation only dumps ~ 180 bytes into the buffer at a time so we don't run out of memory. If the "Attached devices" header isn't required, we can dump the sfile->private bit completely. Signed-off-by: NJeff Mahoney <jeffm@suse.com> Signed-off-by: NJames Bottomley <James.Bottomley@suse.de>

This patch fixes an issue seen where an event occurs which causes the ibmvscsi driver to reset its CRQ. Upon re-registering its CRQ, it receives H_CLOSED, indicating the Virtual I/O Server is not yet ready to receive commands. This resulted in the ibmvscsi driver essentially offlining the adapter and not recovering. The fix is to re-enable our interrupt so that when the Virtual I/O server is ready and sends a CRQ init, we will be able to receive it and resume initialization of the VSCSI adapter.

During performance testing on P7 machines it was observed that the interrupt service routine was doing unnecessary MMIO operations. This patch rearranges the logic of the routine and moves some of the code out of the main routine. The result is that there are now fewer MMIO operations in the performance path of the code. As a result of the above change, an existing condition was exposed where the driver could get an "unexpected" hrrq interrupt. The original code would flag the interrupt as unexpected and then reset the adapter. After further analysis it was confirmed that this condition can occasionally occur and that the interrupt can safely be ignored. Additional code in this patch detects this condition, clears the interrupt and allows the driver to continue without resetting the adapter.

This patch has Support for the new solid state device product SSS6200 from LSI and relavent features w.r.t SSS6200. The major feature added in this driver is supporting Direct-I/O to the SSS6200 storage.There are some additional changes done to avoid exposing the RAID member disks to the OS and hiding/exposing drives based on the OEM Specific Flag in Manufacturing Page10 (this is required to handle specific changes in the SSS6200 firmware). Each and every changes are listed below. 1. Hiding IR related messages. For SSS6200, the driver is modified not to print IR related events. Even if the debugging is enabled the IR related messages will not be displayed. In some places if there is a need to display a message related to IR the string "IR" is replaced with string "DD" and the string "volume" is replaced with "direct drive". But the function names are not changed hence there are some places where the reference to volume can be seen if debug level is set. 2. Removed RAID transport support In Linux the user can retrieve RAID volume information from the sysfs directory. This support is removed for SSS6200. 3. Direct I/O support. The driver tries to enable direct I/O when a volume is reported to the driver by the firmware through IRCC events and the driver does this just before reporting to the OS, hence all the OS issued I/O can go through direct path if they can, The first validation is to see whether the manufacturing page10 flag is set to expose all drives always. If that is set, the driver will not enable direct I/O and displays the message "DDIO" is disabled globally as drives are exposed. The driver checks whether there is more than one volume in the controller, if so the direct I/O will be disabled globally for all volumes in the controller and the message displayed will be "DDIO is disabled globally as number of drives > 1. If retrieving number of PD is failed the driver will not enable direct I/O and displays the message Failure in computing number of drives DDIO disabled. If memory allocation for RAIDVolumePage0 is failed, the driver will not enable direct I/O and displays the message Memory allocation failure for RVPG0 DDIO disabled. If retrieving RAIDVolumePage0 is failed the driver will not enable direct I/O and displays the message Failure in retrieving RVPG0 DDIO disabled If the number of PD in a volume is greater than 8, then the direct I/O will be disabled. If any of individual drives handle retrieval is failed then the DD-IO will be disabled. If the volume is not RAID0 or if the block size is not 512 then the DD-IO will be disabled. If the volume size is greater than 2TB then the DD-IO will be disabled. If the driver is not able to find a valid stripe exponent using the configured stripe size then the DD-IO will be disabled When the DD-IO is enabled the driver will check every I/O request issued to the storage and checks whether the request is either READ6/WRITE6/READ10/WRITE10, if it is and if the complete I/O transfer is within a stripe size then the I/O is redirected to the drive directly instead of the volume. On completion of every I/O, if the completion is failure means if the reply is address reply with a reply frame associated with it, then the type of I/O will be checked, if the I/O is direct then the I/O will be retried to the volume once.
