For v3 hw, we support DIF operation for SAS, but not SATA. In addition, DIF CRC16 is supported. This patchset adds the SW support for the described features. The main components are as follows: - Get protection mask from module param - Fill PI fields - Fill related to DIF in DQ and protection iu memories Signed-off-by:

Certain older adapters such as the OneConnect OCe10100 may not have a valid wqpcnt value. In this case, do not set queue->page_count to 0 in lpfc_sli4_queue_alloc() as this will prevent the driver from initializing.

The same effects can be achieved by setting the dma_boundary to PAGE_SIZE - 1 and the max_segment_size to PAGE_SIZE, so shift those settings into the drivers. Note that in many cases the setting might be bogus, but this keeps the status quo. [mkp: fix myrs and myrb] Signed-off-by:

Most SCSI drivers want to enable "clustering", that is merging of segments so that they might span more than a single page. Remove the ENABLE_CLUSTERING define, and require drivers to explicitly set DISABLE_CLUSTERING to disable this feature. Signed-off-by:

A few drivers were not setting the use_clustering flag at all and thus default to disable. Fix them up to explicitly set this field in preparation for additional cleanups. Signed-off-by:

Commit b5b6e8c8 ("scsi: virtio_scsi: fix IO hang caused by automatic irq vector affinity") removed all virtio_scsi hostdata users.

-
Suganath Prabu authored
Sometimes Aero controllers appears to be returning bad data (0) for doorbell register read and if retries are performed immediately after the bad read, they return good data. Workaround is added to retry read from doorbell registers for maximum three times if driver get the zero. Added functions base_readl_aero for Aero IOC and base_readl for gen35 and other controllers.

Sht->sg_tablesize is set in the driver, and it will be assigned to shost->sg_tablesize in SCSI mid-layer. So it is not necessary to assign shost->sg_table one more time in the driver.

On driver termination, after the driver stops fw logging by writing a register on the chip, the driver immediately unmaps and frees the logging buffer, without confirming in any way that the chip has received the write and terminated the logging. As termination on the chip is not immediate, the chip may issue a dma request to the now unmapped dma buffer, resulting in a iommu fault. Change the driver to receive a confirmation that logging ahs been terminated. As the driver always issues an SLI reset with the device as part of shutdown, and as part of that is receiving confirmation that the reset is complete - the driver was modified to perform the write to disable fw logging prior to the SLI reset and only free the fw log buffer after the SLI reset is complete. That guarantees use of the fw log buffer is fully terminated when it is unmapped. Signed-off-by:

Driver is setting bits in word 10 of the SLI4 ABORT WQE (the wqid). The field was a carry over from a prior SLI revision. The field does not exist in SLI4, and the action may result in an overlap with future definition of the WQE. Remove the setting of WQID in the ABORT WQE. Also cleaned up WQE field settings - initialize to zero, don't bother to set fields to zero. Signed-off-by:

The current discovery state machine the driver treated FLOGI oddly. When point to point, an FLOGI is to be exchanged by the two ports, with the port with the most significant WWN then proceeding with PLOGI. The implementation in the driver was keyed to closely with "what have I sent", not with what has happened between the two endpoints. Thus, it blatantly would ACC an FLOGI, but reject PLOGI's until it had its FLOGI ACC'd. The problem is - the sending of FLOGI may be delayed for some reason, or the response to FLOGI held off by the other side. In the failing situation the other side sent an FLOGI, which was ACC'd, then sent PLOGIs which were then rjt'd until the retry count for the PLOGIs were exceeded and the port gave up. The FLOGI may have been very late in transmit, or the response held off until the PLOGIs failed. Given the other port had the higher WWN, no PLOGIs would occur and communication stopped. Correct the situation by changing the FLOGI handling. Defer any response to an FLOGI until the driver has sent its FLOGI as well. Then, upon either completion of the sent FLOGI, or upon sending an ACC to a received FLOGI (which may be received before or just after FLOGI was sent). the driver will act on who has the higher WWN. if the other port does, the driver will noop any handling of an FLOGI response (if outstanding) and wait for PLOGI. If the local port does, the driver will transition to sending PLOGI and will noop any action on responding to an FLOGI (if not yet received). Fortunately, to implement this, it only took another state flag and deferring any FLOGI response if the FLOGI has yet to be transmit. All subsequent actions were already in place. Signed-off-by:

In some link initialization sequences, the fw generates an erroneous FLOGI payload to the driver without an intervening link bounce. The driver, when it sees a 2nd FLOGI without an intervening link bounce, automatically performs a link bounce. In this, the link bounce causes the situate to repeat and in a nasty loop of link bounces. Resolve the issue by validating the FLOGI payload. The erroneous FLOGI will contain VVL signatures that are not normal. When the driver sees these, it will simply reject the flogi rather than bouncing the link. The reject is consumed within the firmware. Signed-off-by:

Two initiator ports were cable swapped and after swap both went down. The driver internally swaps the nlp nodes based on matching node wwn's but not the same nport id as before. After detecting a change in the nodes RPI, the driver sends an UNREG_RPI command and clears the NLP_RPI_REGISTERED flag, then swaps the node information with the other node. But the other node's NLP_RPI_REGISTERED flag is also cleared, but it is done so without an UNREG_RPI being sent, which causes the later REG_RPI for that other node to fail as the hardware believes its still registered. Additionally, if the node swap occurred while the two nodes had PLOGI's in flight, the fc4_types weren't properly getting swapped such that when the PLOGIs commpleted and PRLI's were then sent, the PRLI's acted on bad protocol types so the PRLI was for the wrong protocol. NVME devices saw SCSI FCP PRLIs and vice versa. Clean up the node swap so that the NLP_RPI_REGISTERED flag is handled properly. Fix the handling of the fc4_types when the nodes are swapped as well Signed-off-by:

Depending on the chipset, the number of NPIV vports may vary and be in excess of what most switches support (256). To avoid confusion with the users, limit the reported NPIV vports to 256.

Driver is hitting null pring pointers in lpfc_do_work(). Pointer assignment occurs based on SLI-revision. If recovering after an error, its possible the sli revision for the port was cleared, making the lpfc_phba_elsring() not return a ring pointer, thus the null pointer. Add SLI revision checking to lpfc_phba_elsring() and status checking to all callers. Signed-off-by:
