ufshcd_get_pwr_dev_param defines an interface for power mode management currently used by both ufs-qcom and ufs-hisi. Move the interface to ufs core so every driver can take advantage of it. Signed-off-by:

devm_reset_control_get could fail, so the fix checks its return value and passes the error code upstream in case it fails. Signed-off-by:

All code from which the OSD include files were included has been removed. Hence also remove the include files themselves. See also commit 19fcae3d ("scsi: remove the SCSI OSD library"). Cc: Christoph Hellwig <hch@lst.de> Cc: Jens Axboe <axboe@kernel.dk> Signed-off-by:

Change the SLI4 queue creation code to use NUMA node based memory allocation based on the cpu the queues will be related to. Signed-off-by:
-
James Smart authored
Currently the driver maintains a sideband structure which has a pointer for each queue element. However, at 8 bytes per pointer, and up to 4k elements per queue, and 100s of queues, this can take up a lot of memory. Convert the driver to using an access routine that calculates the element address based on its index rather than using the pointer table. Signed-off-by:

If all the trunk links drop and a single link resumes, the link_state is not properly reported. When trunked, the driver receives two async cqes. One acqe reports the trunk link states, which the driver records. The other cqe reports the overall state of the trunk. In the failing case, the trunk link state acqe preceeds the overall trunk link state acqe. The trunk link state acqe, as it's an "up" transition, calls a code path which ensures a down transition before moving to the up state. The down transition had a side effect of clearing the just-saved trunk link states. Fix by not clearing the trunk link states if we've already transitioned to a down state. Signed-off-by:

Invalid test is allowing Loop to be a supported topology on G6 and G7 adapters. The chips do not support loop as their link speeds prohibit loop per standard. Correct the conditional so that loop is not reported. Signed-off-by:

If the driver undergoes repeated host resets it starts losing exchange structures and eventually returns SCSI_MLQUEUE_HOST_BUSY and does not recover. The offline path is not reclaiming the outstanding ios on the fcp pring txcmplq before calling lpfc_destroy_multixripool, which causes the txmcplq to be reinit and the resources lost. Flush the fcp rings before destroying the multixripools. Signed-off-by:

The adapter initialization sequence enables interrupts, initializes the adapter link_state to LINK_DOWN, then issues commands to initialize the adapter. The interrupt handler on the adapter validates the link_state (has to be at least LINK_DOWN) and if invalid, will discard the interrupting event. In most cases, there is not a command completion, thus an interrupt until the initialization commands have been sent which is post the setting of state to LINK_DOWN. However, in cases of firmware reset, the reset will modify the link_state to an invalid value (indicating a reset of the adapter) and there occasionally are cases where the adapter will generate an asynchronous event which shares the eq/cq used for mailbox commands. In the failure case, an interrupt is generated immediately after enabling them due to the async event. As link_state is invalid, the eq is list and the CQ not serviced. At this point link_state is initialized and the mailbox command sent. As the CQ has not been serviced, it is not armed, so no interrupt event is generated when the mailbox command completes. Modify the initialization sequence so that interrupts are enabled after link_state is properly initialized, which avoids the race condition with the async event. Signed-off-by:

It's possible for the scsi error handler to fire and call the target reset handler simultaneously to the driver logging out and relogging into the system. If hit just right, the re-login may not have fully re-established the remote port and the rdata->pnod structure may be null. Check for NULL in the reset handler and return failure if NULL.

Current code is using msleep when polling for hw ready. Unfortunately the msleep routine isn't very accurate on rescheduling. In fact, on a busy systems which reset the adapter, it became 10s of seconds before it was rescheduled. Fix by busy waiting using udelay. As we're now busy waiting, significantly reduce the wait time so that we can exit the pool loop as soon as possible. Signed-off-by:

The driver periodically checks for adapter error in a background thread. If the thread detects an error, the adapter will be reset including the deletion and reallocation of workqueues on the adapter. Simultaneously, there may be a user-space request to offline the adapter which may try to do many of the same steps, in parallel, on a different thread. As memory was deallocated while unexpected, the parallel offline request hit a bad pointer. Add coordination between the two threads. The error recovery thread has precedence. So, when an error is detected, a flag is set on the adapter to indicate the error thread is terminating the adapter. But, before doing that work, it will look for a flag that is set by the offline flow, and if set, will wait for it to complete before then processing the error handling path. Similarly, in the offline thread, it first checks for whether the error thread is resetting the adapter, and if so, will then wait for the error thread to finish. Only after it has finished, will it set its flag and offline the adapter. Signed-off-by:

In a couple of cases, the driver detected a pci error (via pci device state or via failed register reads) but didn't take any action to disable the device. Additionally, the driver is ignoring the status of pci configuration space reads. Having the driver take the adapter offline whenever the pci error is detected. Pay attention to pci_config_space_read status and return failure if an error is seen. Signed-off-by:

If an adapter fails, causing a board reset, the board reset routine lpfc_hba_down_s4() takes the hbalock out then calls lpfc_nvmet_ctxbuf_post() who then tries to take out the same lock. As the context lists are now protected under the buf_list_locks, there is no need for the hbalock to be held by the board reset routine. Fix by no longer taking the hbalock in the board reset routine. Signed-off-by:
