lpfc_do_offline(9)

📦 version 7.3.1, in nixpkgs unstable

💅 lpfc_do_offline(9) — like, the Kernel API Manual page, bestie

okay so bestie, this is lpfc_do_offline, straight out of the Kernel API Manual — one function, it fires off a mailbox command and brings that link down. down bad. 🔥

✨ NAME ✨

lpfc_do_offline — issues a mailbox command to bring the link down. that's it. that's the whole vibe. 💅

🦋 SYNOPSIS 🦋

int lpfc_do_offline (struct lpfc_hba *phba , uint32_t type );

🎀 ARGUMENTS 🎀

  • phba — the lpfc_hba pointer. literally just a pointer to your lpfc_hba, no cap 🫶
  • type — one of LPFC_EVT_OFFLINE, LPFC_EVT_WARM_START, or LPFC_EVT_KILL. pick your fighter 💀

💜 NOTES 💜

okay so full transparency, this page has lore. 📖

  • it just goes ahead and assumes any error coming back from lpfc_do_offline will be negative. like, it's built on that assumption, periodt.
  • it can wait up to 5 seconds for the port ring buffers count to hit zero. and if it doesn't hit zero? it prints a warning and keeps going anyway. main character energy, honestly.
  • oh and lpfc_workq_post_event returns a non-zero return code if the call fails — so like, check it. 🙈

🌸 RETURN 🌸

  • -EIO — error posting the event 😭
  • zero — for success ✨ (slay)

and that's the whole page, bestie 🧚 she lives in ./drivers/scsi/lpfc, dated October 2026 — so go forth, bring that link down, and remember: negative errors, five seconds of ring-buffer patience, and a warning if it's not zero. iykyk 💖✨
