Detect failure of controller reset by noticing if the 32 bytes of "driver version" we store on the hardware in the config table fail to get zeroed out. Previously we noticed if the controller did not transition to "simple mode", but this did not detect reset failure if the controller was already in simple mode prior to the reset attempt (e.g. due to module parameter hpsa_simple_mode=1).

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. Signed-off-by:

The code currently computes an offset into a dma_alloc_coherent() area on the assumption that the alignment is imprecise. In fact, the API guarantees PAGE_SIZE alignment, so the offset calculation is always zero: remove it. [jejb: make description actually descriptive] Signed-off-by:

I removed outer loops in ...wait_msgint_ready the sleeptime and retrycount are in fact never changed so I changed them into defines. In arcmsr_flush_hba_cache is a loop removed, which printed the same printk 100 times, one line in log is enough I think. The arcmsr_sleep_for_bus_reset has lost a functionality with the latest patches, The only thing the function does is a long sleep, so it's replaced with a ssleep.

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:

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. Signed-off-by:

Currently the size of the dump generated by the driver is limited in 4MB, which is insufficient to gather much useful data from the new 64 bit adapters. This patch makes the needed changes to increase the dump limit for the 64 bit adapters to 32MB, or even to a bigger value in the future, but keeping the current limitations for the legacy 32 bit adapters.

The SCSI ALUA handler currently fails to attach to devices reporting an UNAVAILABLE/OFFLINE AAS. But given that an UNAVAILABLE/OFFLINE AAS can transition to other states like ACTIVE/OPTIMIZED, ACTIVE/NON-OPTIMIZED, etc. as per SPC4, this ALUA handler behavior should be rectified so as to attach to devices which also report an UNAVAILABLE/OFFLINE AAS.

The first work doesnt complete, because it is waiting for async layer to complete the IOs. The async layer cannot complete the IO as the terminate_rport_io for the second work was not called, which will be called only when the first work completes. Hence the deadlock. To resolve this deadlock, the workqueue allocation has been modified from create_singlethread_workqueue() to alloc_workqueue(). In addition, fc_terminate_rport_io() should be called before the scsi_flush_work() to avoid the similar deadlock as above. scsi fc alloc queue. move terminate rport io before flush Signed-off-by:

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. Signed-off-by:
