💅 lpfc_nvmet_unsol_fcp_buffer(9) — Kernel API Manual

okay so bestie, welcome to the kernel API manual section 9, and today's main character is lpfc_nvmet_unsol_fcp_buffer 🌸 she's a kernel function, she's in the SCSI lpfc driver, and she is literally here to process an unsolicited event data buffer. no cap. let's get into it ✨

🎀 NAME 🎀

lpfc_nvmet_unsol_fcp_buffer — Process an unsolicited event data buffer 💖

✨ SYNOPSIS ✨

void lpfc_nvmet_unsol_fcp_buffer (struct lpfc_hba *phba , uint32_t idx ,
struct rqb_dmabuf *nvmebuf , uint64_t isr_timestamp , uint8_t cqflag );

like, she returns void — no return value, she just does the thing and leaves 💅 periodt.

🫶 ARGUMENTS 🫶

  • phba — pointer to lpfc hba data structure. your hba, your business 🦋
  • idx — relative index of MRQ vector. it's a relative index bestie, not absolute, don't come for me 🙈
  • nvmebuf — pointer to lpfc nvme command HBQ data structure. it's giving "the buffer in question" energy ✨
  • isr_timestamp — in jiffies. yes, jiffies — that's the tick unit, not a snack 😭
  • cqflag — cq processing information regarding workload. it's the little flag that tells you about the workload, iykyk 🔥

🌈 DESCRIPTION 🌈

okay so, the way that this routine works: she's used for processing the WQE associated with a unsolicited event. that's her whole vibe.

first things first, she determines whether there's an existing ndlp that matches the DID from the unsolicited WQE 👀 — like a little vibe check on the DID. and if there isn't one? not me creating a whole new ndlp from the DID in the unsolicited WQE 💅 slay.

then the ELS command from the unsolicited WQE gets used to invoke the proper routine, and to set up the proper state of the discovery state machine 🧚. so she's out here doing matchmaking and state machine setup. main character energy fr fr 👑

the kernel file is right here bestie, go read it:

and the whole friend group 🫶 — all of these are section 9, all iconic:

that's the whole page, bestie, you ate that 🍓 and before you go — this little beauty lives in ./drivers/scsi/lpfc, she was documented in October 2026 ⭐, and yeah she's a section 9 kernel API manual page. mwah 💜 🎀 🦋
