Interest among UFS users in HPB has reduced significantly. I am not aware of any current users of the HPB functionality. Hence remove HPB support from the kernel. A note: the work in JEDEC on a successor for HPB is nearing completion. Zoned storage for UFS or ZUFS combines the UFS standard with ZBC-2. Acked-by:

Because scsi_finish_command() subtracts the residual from the buffer length, residual overflows must not be reported. Reflect this in the SCSI documentation.

Devfreq uses the default DEVFREQ_TIMER_DEFERRABLE mode which uses the deferred timer for scheduling the devfreq load monitor function. This causes the load monitoring to be done only with non-idle CPUs and not making use of the idle CPUs. Hence, use the DEVFREQ_TIMER_DELAYED mode which uses the delayed timer thereby making use of idle CPUs as well for load monitoring. Co-developed-by:

Different behavior were experienced of session being torn down vs not when TMF is timed out. When FW detects the time out, the session is torn down. When driver detects the time out, the session is not torn down. Allow TMF error to return to upper layer without session tear down. Cc: stable@vger.kernel.org Signed-off-by:

Task management can retry up to 5 times when FW resource becomes bottle neck. Between the retries, there is a short sleep. Current code assumes the chip has not reset or session has not changed.

Connection does not resume after a host reset / chip reset. The cause of the blockage is due to the FCF_ASYNC_ACTIVE left on. The gnl command was interrupted by the chip reset. On exiting the command, this flag should be turn off to allow relogin to reoccur. Clear this flag to prevent blockage.

Link up failure occurred where driver failed to see certain events from FW indicating link up (AEN 8011) and fabric login completion (AEN 8014). Without these 2 events, driver would not proceed forward to scan the fabric. The cause of this is due to delay in the receive of interrupt for Mailbox 60 that causes qla to set the fw_started flag late. The late setting of this flag causes other interrupts to be dropped. These dropped interrupts happen to be the link up (AEN 8011) and fabric login completion (AEN 8014). Set fw_started flag early to prevent interrupts being dropped.

For each TMF request, driver iterates through each qpair and flushes commands associated to the TMF. At the end of the qpair flush, a Marker is used to complete the flush transaction. This process was repeated for each qpair. The multiple flush and marker for this TMF request seems to cause confusion for FW. Instead, 1 flush is sent to FW. Driver would wait for FW to go through all the I/Os on each qpair to be read then return. Driver then closes out the transaction with a Marker.

During NVMe queue creation, a new qpair is created. FW resource limit needs to be re-adjusted to take into account the new qpair. Otherwise, NVMe command can not go through. This issue was discovered while testing/forcing FW execution to fail at load time. Add call to readjust IOCB and exchange limit. In addition, get FW state command and require FW to be running. Otherwise, error is generated. Cc: stable@vger.kernel.org Signed-off-by:

Currently, we have dated logic to work around the differences between SLI-4 and SLI-3 resource reporting through sysfs. Leave the SLI-3 path untouched, but for SLI4 path, retrieve resource values from the phba->sli4_hba->max_cfg_param structure. Max values are populated during ACQE events right after READ_CONFIG mbox cmd is sent. Instead of the dated subtraction logic, used resource calculation is directly fed into sysfs for display.

A mailbox timeout error usually indicates something has gone wrong, and a follow up reset of the HBA is a typical recovery mechanism. Introduce a MBX_TMO_ERR flag to detect such cases and have lpfc_els_flush_cmd abort ELS commands if the MBX_TMO_ERR flag condition was set. This ensures all of the registered SGL resources meant for ELS traffic are not leaked after an HBA reset. Signed-off-by:

This patch provides better target rport recovery when a target rport is running in initiator mode to discover the fabric. Such a target will issue a LOGO before switching back to strict target mode and changes are made to recover the login. Log messages are also updated accordingly. Signed-off-by:

Previously, Establish Image Pair was set in all PRLI_ACC responses regardless if the received PRLI was from an initiator or target function. Specific target vendors that can operate in both initiator and target mode, may view the PRLI_ACC with Establish Image Pair set as an invalid service parameter when operating in initiator only mode. This causes discovery issues later when the target switches on its target mode function. Revise logic that determines an rport's role as an initiator or target and set the Establish Image Pair service parameter bit only if the Target Function bit is set. Signed-off-by:

The ndlp kref count implementation in lpfc_dev_loss_tmo_callbk() removes the initial node reference when a vport is unloading. When lpfc_cleanup() sends a DEVICE_RM event and is in NPR state, the driver calls lpfc_drop_node(). Subsequently, lpfc_drop_node() also removes an ndlp kref thinking it is the initial reference. This unintentionally introduces an extra kref decrement on the ndlp object. Fix by using the NLP_DROPPED node flag in lpfc_dev_loss_tmo_callbk() and lpfc_drop_node() to coordinate the removal of the initial node reference. In lpfc_dev_loss_tmo_callbk(), remove the SCSI transport reference provided the node is registered in the dev_loss context because the driver cannot call the SCSI transport in dev_loss context or afterwards. And, have lpfc_drop_node() not remove a reference if another thread is acting or has already acted on it. Signed-off-by:

Conditionalize when to put an ndlp into recovery mode when processing RSCNs. As long as an ndlp state is beyond a PLOGI issue and has been mapped to a transport layer before, the ndlp qualifies to be put into recovery mode. Otherwise, treat the ndlp rport normally through the discovery engine. Signed-off-by:

In lpfc_cmpl_els_flogi(), the return out: label decrements the ndlp kref signaling that FLOGI processing on the ndlp is complete. In loop topology path, there is an unnecessary ndlp put because it also branches to the out: label. This also signals ndlp usage completion too soon. As such, remove the extra lpfc_nlp_put() when in loop topology. Signed-off-by:

The driver is reaching into a nvme_fc_cmd_iu ptr that belongs to the transport during an abort. This could cause an unintentional ptr dereference into memory that the driver does not own. Since the nvme_fc_cmd_iu ptr was for logging purposes only, simplify the log message such that the nvme_fc_cmd_iu reference is no longer needed. Signed-off-by:

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes. Signed-off-by:

Currently spinlock hisi_hba->lock is used by both interrupts and threads which requires the use of spin_lock_irqsave()/spin_unlock_irqrestore(). However, some places still use spin_lock()/spin_unlock(). Reviewing the code revealed that it is unnecessary to use hisi_hba->lock in the function hisi_sas_port_notify_formed() which is the only place that uses the spinlock in interrupt context. So delete unused lock in hisi_sas_port_notify_formed(). Signed-off-by:

When FIO and debugfs snapshot occur concurrently, some SATA I/Os are failed to return to the upper layer due to the setting of HISI_SAS_REJECT_CMD_BIT. Then the SCSI layer invokes the error processing thread. However, sas_ata_hard_reset() in EH also fails to be reset due to the setting of HISI_SAS_REJECT_CMD_BIT. As a result, the device is disabled.
