scsi: lpfc: Change FA-PWWN detection methodology Do not rely on vendor version field of the CSPs to determine if we are in a FA-PWWN environment. Instead, use the following procedure: First, during HBA initialization, driver does a READ_CONFIG to determine if FA-PWWN is configured on the HBA. A LPFC_FAWWPN_CONFIG hba_flag is set accordingly. Next, when the link comes up before the driver gets a link up event, the firmware logs into the fabric with FA-PWWN. If the fabric port does not support FA-PWWN, the driver will get a Misconfigured FA-WWN async event before the link up. A LPFC_FAWWPN_FABRIC hba_flag will be set accordingly. Finally, if the fabric supports FA-PWWN, the firmware will replace its CSPs WWN with the Fabric Assigned ones. Then after link up, the driver will retrieve the Fabric Assigned WWN when it does a READ_SPARAM mbox command.

scsi: lpfc: SLI path split: Refactor base ELS paths and the FLOGI path The patch refactors the general ELS handling paths to migrate to SLI-4 structures or common element abstractions. The fabric login paths are revised as part of this patch: - New generic lpfc_sli_prep_els_req_rsp jump table routine - Introduce ls_rjt_error_be and ulp_bde64_le unions to correct legacy endianness assignments - Conversion away from using SLI-3 iocb structures to set/access fields in common routines. Use the new generic get/set routines that were added. This move changes code from indirect structure references to using local variables with the generic routines. - Refactor routines when setting non-generic fields, to have both SLI3 and SLI4 specific sections. This replaces the set-as-SLI3 then translate to SLI4 behavior of the past. - Clean up poor indentation on some of the ELS paths Link: https://lore.kernel.org/r/20220225022308.16486-5-jsmart2021@gmail.com Co-developed-by: Justin Tee <justin.tee@broadcom.com> Signed-off-by: Justin Tee <justin.tee@broadcom.com> Signed-off-by: James Smart <jsmart2021@gmail.com> Signed-off-by: Martin K.

scsi: lpfc: Fix CPU to/from endian warnings introduced by ELS processing The kernel test robot reported the following sparse warning: ".../lpfc_els.c:3984:25: sparse: sparse: cast from restricted __be16" For the error being flagged, using be32_to_cpu() on a be16 data type, it was simple enough. But a review of other elements and warnings were also evaluated. This patch corrected several items in the original patch: - Using be32_to_cpu() on a be16 data type - cpu_to_le32() used on a std uint32_t (CPU) data type. Note: This is a byte array, but stored in LE layout by hardware at 32-bit boundaries. So it possibly needed conversion. - Using cpu_to_le32() on a std uint16_t and assigned to a char typeA - Using le32_to_cpu() on a le16 type - Missing cpu_to_le16() on an assignment Link: https://lore.kernel.org/r/20210830231243.6227-1-jsmart2021@gmail.com Fixes: 9064aeb2df8e ("scsi: lpfc: Add EDC ELS support") Reported-by: kernel test robot <lkp@intel.com> Co-developed-by: Justin Tee <justin.tee@broadcom.com> Signed-off-by: Justin Tee <justin.tee@broadcom.com> Signed-off-by: James Smart <jsmart2021@gmail.com> Signed-off-by: Martin K.

For the new framework MIB support also requires active enablement of support via the SET_FEATURES command with the firmware.

This ensures detection after firmware download. - Update SET_FEATURES mbx command for the MIB enablement feature and add support for the feature. - Create the cmf_setup routine to encapsulate the detection of MIB support and perform the enablement of the MIB support feature.

scsi: lpfc: add RDF registration and Link Integrity FPIN logging This patch modifies lpfc to register for Link Integrity events via the use of an RDF ELS and to perform Link Integrity FPIN logging. Specifically, the driver was modified to: - Format and issue the RDF ELS immediately following SCR registration. This registers the ability of the driver to receive FPIN ELS. - Adds decoding of the FPIN els into the received descriptors, with logging of the Link Integrity event information. After decoding, the ELS is delivered to the scsi fc transport to be delivered to any user-space applications. - To aid in logging, simple helpers were added to create enum to name string lookup functions that utilize the initialization helpers from the fc_els.h header. - Note: base header definitions for the ELS's don't populate the descriptor payloads. As such, lpfc creates it's own version of the structures, using the base definitions (mostly headers) and additionally declaring the descriptors that will complete the population of the ELS.

This patch adds private-loop FC-AL support for the LPE32000 adapters when a link is 8G or below. To avoid conditions where link rate may change, which would cause non-connectivity to the AL device, FC-AL mode must become a persistent setting and the link kept at a speed supporting FC-AL.

scsi: lpfc: Revise interrupt coalescing for missing scenarios The existing "auto eq delay" mechanism was sometimes skipping over an EQ, not ramping the coalescing down under light load fast enough, and in other cases never kicked in as cpu sharing by multiple vectors didn't quite add up right. Tweak the interrupt mechanism such that: - Add a flag to the EQ to force checking for colaescing values when being serviced in the interrupt handler. The flag will be set by any CQ bound to the EQ whenever the number of CQ elements process in a single scan meets or exceeds the hardware queue notify level. E.g. there's a significant number of completions happening. - In the heartbeat work item that checks coalescing: - Replace the structure that was counting the number of EQs that interrupted on a single cpu with a new structure that looks at the EQ to see whether EQ currently has a coalescing value (thus it should be re-evaluate) or was marked by the new flag indicating heavy completions. - When a cpu, which may be servicing multiple vectors, had at least 1 EQ that should be checked, a new coalescing delay is calculated based on the number of interrupts that occurred on the cpu. - The new coalescing value is then applied to the EQs that had interrupted on the cpu.

scsi: lpfc: Fix NVMe ABTS in response to receiving an ABTS When the port, running as a nvme target, receives an ABTS, it submits commands to the adapter to Abort i/o outstanding in the adapter. The Abort command formatting routine left a command field set to zero, which instructs the adapter to generate an ABTS on the wire as part of cleaning up the I/O. This is common operation for an initiator, but not for a target. Fix the driver to check whether an ABTS had been received for the I/O, and if so, change the Abort command formatting so that the ABTS generation is disabled (IA=1). No need to ABTS it when the other side already has. Also refactored the code such that there is a single routine being used for nvme or nvmet ABORT requests, and IA is an argument.

scsi: lpfc: Support dynamic unbounded SGL lists on G7 hardware. Typical SLI-4 hardware supports up to 2 4KB pages to be registered per XRI to contain the exchanges Scatter/Gather List. This caps the number of SGL elements that can be in the SGL. There are not extensions to extend the list out of the 2 pages. The G7 hardware adds a SGE type that allows the SGL to be vectored to a different scatter/gather list segment. And that segment can contain a SGE to go to another segment and so on. The initial segment must still be pre-registered for the XRI, but it can be a much smaller amount (256Bytes) as it can now be dynamically grown. This much smaller allocation can handle the SG list for most normal I/O, and the dynamic aspect allows it to support many MB's if needed. The implementation creates a pool which contains "segments" and which is initially sized to hold the initial small segment per xri. If an I/O requires additional segments, they are allocated from the pool. If the pool has no more segments, the pool is grown based on what is now needed. After the I/O completes, the additional segments are returned to the pool for use by other I/Os. Once allocated, the additional segments are not released under the assumption of "if needed once, it will be needed again". Pools are kept on a per-hardware queue basis, which is typically 1:1 per cpu, but may be shared by multiple cpus. The switch to the smaller initial allocation significantly reduces the memory footprint of the driver (which only grows if large ios are issued). Based on the several K of XRIs for the adapter, the 8KB->256B reduction can conserve 32MBs or more. It has been observed with per-cpu resource pools that allocating a resource on CPU A, may be put back on CPU B. While the get routines are distributed evenly, only a limited subset of CPUs may be handling the put routines. This can put a strain on the lpfc_put_cmd_rsp_buf_per_cpu routine because all the resources are being put on a limited subset of CPUs.

scsi: lpfc: Rework EQ/CQ processing to address interrupt coalescing When driving high iop counts, auto_imax coalescing kicks in and drives the performance to extremely small iops levels. There are two issues: 1) auto_imax is enabled by default. The auto algorithm, when iops gets high, divides the iops by the hdwq count and uses that value to calculate EQ_Delay. The EQ_Delay is set uniformly on all EQs whether they have load or not. The EQ_delay is only manipulated every 5s (a long time). Thus there were large 5s swings of no interrupt delay followed by large/maximum delay, before repeating. 2) When processing a CQ, the driver got mixed up on the rate of when to ring the doorbell to keep the chip appraised of the eqe or cqe consumption as well as how how long to sit in the thread and process queue entries. Currently, the driver capped its work at 64 entries (very small) and exited/rearmed the CQ. Thus, on heavy loads, additional overheads were taken to exit and re-enter the interrupt handler. Worse, if in the large/maximum coalescing windows,k it could be a while before getting back to servicing. The issues are corrected by the following: - A change in defaults. Auto_imax is turned OFF and fcp_imax is set to 0. Thus all interrupts are immediate. - Cleanup of field names and their meanings. Existing names were non-intuitive or used for duplicate things. - Added max_proc_limit field, to control the length of time the handlers would service completions. - Reworked EQ handling: Added common routine that walks eq, applying notify interval and max processing limits. Use queue_claimed to claim ownership of the queue while processing. Always rearm the queue whenever the common routine is called. Rework queue element processing, namely to eliminate hba_index vs host_index. Only one index is necessary. The queue entry can be marked invalid and the host_index updated immediately after eqe processing. After rework, xx_release routines are now DB write functions. Renamed the routines as such. Moved lpfc_sli4_eq_flush(), which does similar action, to same area. Replaced the 2 individual loops that walk an eq with a call to the common routine. Slightly revised lpfc_sli4_hba_handle_eqe() calling syntax. Added per-cpu counters to detect interrupt rates and scale interrupt coalescing values. - Reworked CQ handling: Added common routine that walks cq, applying notify interval and max processing limits. Use queue_claimed to claim ownership of the queue while processing. Always rearm the queue whenever the common routine is called. Rework queue element processing, namely to eliminate hba_index vs host_index. Only one index is necessary. The queue entry can be marked invalid and the host_index updated immediately after cqe processing. After rework, xx_release routines are now DB write functions. Renamed the routines as such. Replaced the 3 individual loops that walk a cq with a call to the common routine. Redefined lpfc_sli4_sp_handle_mcqe() to commong handler definition with queue reference. Add increment for mbox completion to handler. - Added a new module/sysfs attribute: lpfc_cq_max_proc_limit To allow dynamic changing of the CQ max_proc_limit value being used. Although this leaves an EQ as an immediate interrupt, that interrupt will only occur if a CQ bound to it is in an armed state and has cqe's to process. By staying in the cq processing routine longer, high loads will avoid generating more interrupts as they will only rearm as the processing thread exits. The immediately interrupt is also beneficial to idle or lower-processing CQ's as they get serviced immediately without being penalized by sharing an EQ with a more loaded CQ.

scsi: lpfc: Support non-uniform allocation of MSIX vectors to hardware queues So far MSIX vector allocation assumed it would be 1:1 with hardware queues. However, there are several reasons why fewer MSIX vectors may be allocated than hardware queues such as the platform being out of vectors or adapter limits being less than cpu count. This patch reworks the MSIX/EQ relationships with the per-cpu hardware queues so they can function independently. MSIX vectors will be equitably split been cpu sockets/cores and then the per-cpu hardware queues will be mapped to the vectors most efficient for them.

scsi: lpfc: Allow override of hardware queue selection policies Default behavior is to use the information from the upper IO stacks to select the hardware queue to use for IO submission. Which typically has good cpu affinity. However, the driver, when used on some variants of the upstream kernel, has found queuing information to be suboptimal for FCP or IO completion locked on particular cpus. For command submission situations, the lpfc_fcp_io_sched module parameter can be set to specify a hardware queue selection policy that overrides the os stack information. For IO completion situations, rather than queing cq processing based on the cpu servicing the interrupting event, schedule the cq processing on the cpu associated with the hardware queue's cq.

scsi: lpfc: Adding ability to reset chip via pci bus reset This patch adds a "pci_bus_reset" option to the board_mode sysfs attribute. This option uses the pci_reset_bus() api to reset the PCIe link the adapter is on, which will reset the chip/adapter. Prior to issuing this option, all functions on the same chip must be placed in the offline state by the admin. After the reset, all of the instances may be brought online again. The primary purpose of this functionality is to support cases where firmware update required a chip reset but the admin did not want to reboot the machine in order to instantiate the firmware update. Sanity checks take place prior to the reset to ensure the adapter is the sole entity on the PCIe bus and that all functions are in the offline state.

scsi: lpfc: add Trunking support Add trunking support to the driver. Trunking is found on more recent asics. In general, trunking appears as a single "port" to the driver and overall behavior doesn't differ. Link speed is reported as an aggregate value, while link speed control is done on a per-physical link basis with all links in the trunk symmetrical. Some commands returning port information are updated to additionally provide trunking information. And new ACQEs are generated to report physical link events relative to the trunk. This patch contains the following modifications: - Added link speed settings of 128GB and 256GB. - Added handling of trunk-related ACQEs, mainly logging and trapping of physical link statuses. - Added additional bsg interface to query trunk state by applications. - Augment link_state sysfs attribtute to display trunk link status Signed-off-by: Dick Kennedy <dick.kennedy@broadcom.com> Signed-off-by: James Smart <jsmart2021@gmail.com> Reviewed-by: Hannes Reinecke <hare@suse.com> Signed-off-by: Martin K.

scsi: lpfc: add support to retrieve firmware logs This patch adds the ability to read firmware logs from the adapter. The driver registers a buffer with the adapter that is then written to by the adapter. The adapter posts CQEs to indicate content updates in the buffer. While the adapter is writing to the buffer in a circular fashion, an application will poll the driver to read the next amount of log data from the buffer. Driver log buffer size is configurable via the ras_fwlog_buffsize sysfs attribute. Verbosity to be used by firmware when logging to host memory is controlled through the ras_fwlog_level attribute. The ras_fwlog_func attribute enables or disables loggy by firmware.

scsi: lpfc: Work around NVME cmd iu SGL type The hardware offload for NVME commands was created when the FC-NVME standard was setting SGL Descriptor Type to SGL Data Block Descriptor (0h) and SGL Descriptor Sub Type to Address (0h). A late change in NVMe-over-Fabrics obsoleted these values, creating a transport SGL descriptor type with new values to go into these fields. For initial hardware support, in order to be compliant to the spec, use host-supplied cmd IU buffers instead of the adapter generated values. Later hardware will correct this. Add a module parameter to override this offload disablement if looking for lowest latency. This is reasonable as nothing in FC-NVME uses the SQE SGL values.

WQ creation differs slightly to ask for a WQ to be DPP-ized. When submitting a WQE to a DPP WQ, it is submitted to the host memory for the WQ normally, but is also written by the host cpu directly to a BAR aperture. Write buffer coalescing in hardware is (hopefully) turned on, enabling single pci write operation support. The doorbell is thing rung to indicate the WQE is available and was pushed to the aperture.

However, under heavy io load, the host cpu is pushing commands faster than the drain rate of the adapter causing the driver to resource busy commands. Enlarge the hardware queue (wq & cq) to support a larger number of queue entries (4x the prior size) before backpressure. Enlarging the queue requires larger contiguous buffers (16k) per logical page for the hardware. This changed calling sequences that were expecting 4K page sizes that now must pass a parameter with the page sizes. It also required use of a new version of an adapter command that can vary the page size values.

Update ABORT processing for NVMET. The driver with nvme had this routine stubbed. Right now XRI_ABORTED_CQE is not handled and the FC NVMET Transport has a new API for the driver. Missing code path, new NVME abort API Update ABORT processing for NVMET There are 3 new FC NVMET Transport API/ template routines for NVMET: lpfc_nvmet_xmt_fcp_release This NVMET template callback routine called to release context associated with an IO This routine is ALWAYS called last, even if the IO was aborted or completed in error. lpfc_nvmet_xmt_fcp_abort This NVMET template callback routine called to abort an exchange that has an IO in progress nvmet_fc_rcv_fcp_req When the lpfc driver receives an ABTS, this NVME FC transport layer callback routine is called. For this case there are 2 paths thru the driver: the driver either has an outstanding exchange / context for the XRI to be aborted or not. If not, a BA_RJT is issued otherwise a BA_ACC NVMET Driver abort paths: There are 2 paths for aborting an IO. The first one is we receive an IO and decide not to process it because of lack of resources. An unsolicated ABTS is immediately sent back to the initiator as a response. lpfc_nvmet_unsol_fcp_buffer lpfc_nvmet_unsol_issue_abort (XMIT_SEQUENCE_WQE) The second one is we sent the IO up to the NVMET transport layer to process, and for some reason the NVME Transport layer decided to abort the IO before it completes all its phases. For this case there are 2 paths thru the driver: the driver either has an outstanding TSEND/TRECEIVE/TRSP WQE or no outstanding WQEs are present for the exchange / context. lpfc_nvmet_xmt_fcp_abort if (LPFC_NVMET_IO_INP) lpfc_nvmet_sol_fcp_issue_abort (ABORT_WQE) lpfc_nvmet_sol_fcp_abort_cmp else lpfc_nvmet_unsol_fcp_issue_abort lpfc_nvmet_unsol_issue_abort (XMIT_SEQUENCE_WQE) lpfc_nvmet_unsol_fcp_abort_cmp Context flags: LPFC_NVMET_IOP - his flag signifies an IO is in progress on the exchange. LPFC_NVMET_XBUSY - this flag indicates the IO completed but the firmware is still busy with the corresponding exchange. The exchange should not be reused until after a XRI_ABORTED_CQE is received for that exchange. LPFC_NVMET_ABORT_OP - this flag signifies an ABORT_WQE was issued on the exchange. LPFC_NVMET_CTX_RLS - this flag signifies a context free was requested, but we are deferring it due to an XBUSY or ABORT in progress. A ctxlock is added to the context structure that is used whenever these flags are set/read within the context of an IO. The LPFC_NVMET_CTX_RLS flag is only set in the defer_relase routine when the transport has resolved all IO associated with the buffer. The flag is cleared when the CTX is associated with a new IO. An exchange can has both an LPFC_NVMET_XBUSY and a LPFC_NVMET_ABORT_OP condition active simultaneously. Both conditions must complete before the exchange is freed. When the abort callback (lpfc_nvmet_xmt_fcp_abort) is envoked: If there is an outstanding IO, the driver will issue an ABORT_WQE. This should result in 3 completions for the exchange: 1) IO cmpl with XB bit set 2) Abort WQE cmpl 3) XRI_ABORTED_CQE cmpl For this scenerio, after completion #1, the NVMET Transport IO rsp callback is called. After completion #2, no action is taken with respect to the exchange / context. After completion #3, the exchange context is free for re-use on another IO. If there is no outstanding activity on the exchange, the driver will send a ABTS to the Initiator. Upon completion of this WQE, the exchange / context is freed for re-use on another IO.

On link up driver gets updated service parameter with FAWWN assigned port name. Driver sends 2nd FLOGI with updated fawwpn and modifies the vport->fc_portname in driver. Note: Soft wwpn will not be allowed when fawwpn is enabled.

scsi: lpfc: NVME Initiator: Base modifications NVME Initiator: Base modifications This patch adds base modifications for NVME initiator support. The base modifications consist of: - Formal split of SLI3 rings from SLI-4 WQs (sometimes referred to as rings as well) as implementation now widely varies between the two. - Addition of configuration modes: SCSI initiator only; NVME initiator only; NVME target only; and SCSI and NVME initiator. The configuration mode drives overall adapter configuration, offloads enabled, and resource splits. NVME support is only available on SLI-4 devices and newer fw. - Implements the following based on configuration mode: - Exchange resources are split by protocol; Obviously, if only 1 mode, then no split occurs. Default is 50/50. module attribute allows tuning. - Pools and config parameters are separated per-protocol - Each protocol has it's own set of queues, but share interrupt vectors. SCSI: SLI3 devices have few queues and the original style of queue allocation remains. SLI4 devices piggy back on an "io-channel" concept that eventually needs to merge with scsi-mq/blk-mq support (it is underway). For now, the paradigm continues as it existed prior. io channel allocates N msix and N WQs (N=4 default) and either round robins or uses cpu # modulo N for scheduling. A bunch of module parameters allow the configuration to be tuned. NVME (initiator): Allocates an msix per cpu (or whatever pci_alloc_irq_vectors gets) Allocates a WQ per cpu, and maps the WQs to msix on a WQ # modulo msix vector count basis. Module parameters exist to cap/control the config if desired. - Each protocol has its own buffer and dma pools. I apologize for the size of the patch.

[SCSI] lpfc 8.3.26: Fix HBA initialization issues Fix HBA initialization issues - Swap all values that come from the firmware image on little endian systems. Created a new bf_get_be macro that does the same as the bf_get_le macro but for big endian data instead of little endian data. - Moved the incrementing of temp_offset after the copy fixed the write object loop to use temp_offset to figure out where the end of the image is instead of offset. - Added the necessary codes for properly bringing the driver instance offline and then trying to bring the port back online with the PCI function IP reset. If it fails to bring the SLI port back online, it will fall through to bringing the SLI port to HBA error offline. - Add a call in the probe_one_s3 and probe_one_s4 routines to get the Modeldesc - Change OCe50100 to OCe15100 - Made the error log also include the PCI BAR bitmap returned from kernel call pci_select_bars().
