Merge patch series "Update lpfc to revision 15.0.0.0"

2026-04-03T01:35:53+00:00

Justin Tee says: Update lpfc to revision 15.0.0.0 This patch set adds support for the G8 ASIC found on the LPe42100 series adapter models. Updates are made to irq affinity assignment, mailbox command handling related to initialization, SGL construction, firmware download diagnostics, and the removal of an outdated performance feature. We also add 128G link speed selection and support. The patches were cut against Martin's 7.1/scsi-queue tree.

scsi: lpfc: Introduce 128G link speed selection and support

2026-04-03T01:34:02+00:00

128G link speed selection and support is added for various mailbox commands, defines, and ACQE handling. The default behavior to autonegotiate supported link speed remains the same.

scsi: lpfc: Check ASIC_ID register to aid diagnostics during failed fw updates

2026-04-03T01:34:02+00:00

When WRITE_OBJECT mailbox command fails during firmware update, the lpfc_log_write_firmware_error() routine is used to log and parse commonly found error codes. Update this routine to also include ASIC_ID register checks for notifying users of incompatible images.

scsi: lpfc: Update construction of SGL when XPSGL is enabled

2026-04-03T01:34:02+00:00

The construction of SGLs is updated to safeguard ASIC boundary requirements when using XPSGL. The LSP type SGE is used to notify where a continuing SGL resides. Typically, this means that the LSP is the last SGE in an SGL because the current SGL has reached its maximum size and the LSP is used to refer to the next follow up SGL. Due to ASIC boundary requirements, there is a need to ensure a 4 KB boundary is not crossed. Thus, for a maximum size of 256 byte SGLs or 16 SGEs, this means restricting the LSP to being the 12th SGE for the very first SGL that is used for pre-registration. If additional SGEs are needed, the LSP will be the last SGE position within that follow up SGL as was previously implemented.

scsi: lpfc: Add REG_VFI mailbox cmd error handling

2026-04-03T01:34:01+00:00

If lpfc_issue_reg_vfi() returns an error in lpfc_rcv_plogi(), then execution of lpfc_rcv_plogi() continues and lpfc_reg_rpi() is called, which allocates an mbuf. When this REG_RPI mailbox is issued, it inevitably fails because the VFI is not registered. However, the REG_RPI failure does not free the mbuf that was allocated in lpfc_reg_rpi() because there is no check for mbox error status in lpfc_defer_plogi_acc(). Fix by adding a check in lpfc_rcv_plogi() if lpfc_reg_vfi() fails, then exit early. Also, add mailbox status check in lpfc_defer_plogi_acc to enter the REG_RPI mbox_cmpl functions and free the allocated mbuf.

scsi: lpfc: Log MCQE contents for mbox commands with no context

2026-04-03T01:34:01+00:00

Update log message to display the entirety of an MCQE for which there is no submission context. This log message is not expected to occur and hence is tagged as a LOG_TRACE_EVENT. As such, move the hbalock release to before this log message so that the trace event process does not hold the hbalock for too long.

scsi: lpfc: Select mailbox rq_create cmd version based on SLI4 if_type

2026-04-03T01:34:01+00:00

When specifying rq version, it is preferred to refer to SLI4 interface type instead of the get_sli4_parameters mailbox command response. If SLI4 if_type is 2 or above, then the newer version 1 is used for rq_create mailbox commands. Otherwise, version 0 is used and is meant for older adapters.
