2024-05-06scsi: lpfc: Add support for 32 byte CDBsJustin Tee1-0/+8
The driver's I/O path is updated to support 32 byte CDBs. Changes to accommodate 32 byte CDBs include: - Updating various size fields to allow for the larger 32 byte CDB. - Starting the FCP command payload at an earlier offset in WQE submission to fit the 32 byte CDB. - Redefining relevant structs to __le32/__be32 data types for proper cpu endianness macro usage.

2022-04-18scsi: lpfc: Change FA-PWWN detection methodologyJames Smart1-0/+3
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.

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.

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.

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.

MIB support is currently limited to detecting support in the adapter and ensuring FDMI support is enabled if present. For the new framework MIB support also requires active enablement of support via the SET_FEATURES command with the firmware. Rework the MIB detection and enablement for the following: - Move detection away from the get_sli4_parameters routine, and into the hba_setup path. get_sli4_parameters is only called once at attachment while hba_setup is called as part of any SLI port reset path. 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.

2021-04-13scsi: lpfc: Remove unsupported mbox PORT_CAPABILITIES logicJames Smart1-173/+1
SLI-4 does not contain a PORT_CAPABILITIES mailbox command (only SLI-3 does, and SLI-3 doesn't use it), yet there are SLI-4 code paths that have code to issue the command. The command will always fail. Remove the code for the mailbox command and leave only the resulting "failure path" logic.

2020-11-17scsi: lpfc: Refactor WQE structure definitions for common useJames Smart1-3/+7
In preparation of reworking the driver to use a native SLI-4 WQE interface for the SCSI and NVMe I/O paths, start by commonizing the WQE exchange type and command type attributes. While adjusting these options also noted the variance in the pbde field. Fix this by setting templates to 0 and in NVMe, which explicitly uses this option, setting the value.

2020-10-26scsi: lpfc: Add FDMI Vendor MIB supportJames Smart1-2/+8
Created new attribute lpfc_enable_mi, which by default is enabled. Add command definition bits for SLI-4 parameters that recognize whether the adapter has MIB information support and what revision of MIB data. Using the adapter information, register vendor-specific MIB support with FDMI. The registration will be done every link up. During FDMI registration, encountered a couple of errors when reverting to FDMI rev1. Code needed to exist once reverting. Fixed these.

2020-02-18scsi: lpfc: add RDF registration and Link Integrity FPIN loggingJames Smart1-0/+19
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.

When the WriteObject mailbox response has change_status set to is 0x2 (Firmware Reset) or 0x04 (Port Migration Reset), the CSF field should also be checked to see if a fw reset is sufficient to enable all new features in the updated firmware image. If not, a fw reset would start the new firmware, but with a feature level equal to existing firmware. To enable the new features, a chip reset/pci slot reset would be required. Check the CSF bit when change_status is 0x2 or 0x4 to know whether to perform a pci bus reset or fw reset.

2019-10-24scsi: lpfc: Add FC-AL support to lpe32000 modelsJames Smart1-0/+12
In the past, the lpe32000 models, based their main support being for 32G, and as FC-AL is not supported in the FC standards past 8G, did not support FC-AL operation. 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. The patch: - Adds a pls attribute indicating whether the adapter properly supports FC-AL. - Adds support for the adapter to indicate that topology should be fixed and the topology types to be configured. - Adds a pt attribute to report the persistent topology if present.

2019-10-24scsi: lpfc: Revise interrupt coalescing for missing scenariosJames Smart1-1/+0
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.
