lpfc_mq_create_fb_init(9)

📦 version 7.3.1, in nixpkgs unstable

💖 lpfc_mq_create_fb_init ✨

okay bestie, welcome to lpfc_mq_create_fb_init(9) — this is a page straight out of the Kernel API Manual and it's lowkey a tiny little icon. it does one job and it does it with zero drama. let's get into it 🎀

🌸 NAME 🌸

lpfc_mq_create_fb_init — send MCC_CREATE without the async events registration. that's the whole vibe. no cap. 💅

🦋 SYNOPSIS 🦋

void lpfc_mq_create_fb_init (struct lpfc_hba *phba , struct lpfc_queue
*mq , LPFC_MBOXQ_t *mbox , struct lpfc_queue *cq );

it returns void bestie, because (spoiler) it literally cannot fail 😭✨

🎀 ARGUMENTS 🎀

  • phba — the HBA structure, aka the thing that tells you which port we're making a queue on. it's giving "main character pointer energy" 👑
  • mq — the queue structure you use to create the mailbox queue. yes queen, build it 🫶
  • mbox — an allocated pointer to type LPFC_MBOXQ_t. allocated already, don't come in here with a raw uninitialized one 🙈
  • cq — the completion queue to associate with this cq. they're a package deal, fr fr 💜

⭐ DESCRIPTION ⭐

so here's the lore: this function is the failback function — that's the (fb) in the name, iykyk — and it kicks in when mq_create_ext fails on older FW generations. it's the backup dancer that ate and left no crumbs. 🔥

other than that one little detail, its purpose is identical to mq_create_ext. same mission, same energy, different generation of firmware. 🌈

and here's the slay part: this routine cannot fail, because all the attributes were previously accessed and initialized back in mq_create_ext. everything it needs was already prepped. it's just showing up and doing the thing 💅✨

ngl the "cannot fail" line is the most iconic thing on this whole page — the work was already done upstream, this is purely the failback path. 🧚

👑 SEE ALSO 👑

bestie. buckle up. 🍓 this list is long — like, "group chat has 300 unread messages" long — but every single one is here, no skipping, no cap:

Kernel file ./drivers/scsi/lpfc/lpfc_sli.c

like… that's the whole extended universe, bestie 🌌💀 every single one present and accounted for. mwah 😘

that's the page!! go create that mailbox queue without async event registration, you absolute queen 👑✨

and for the cute sign-off: this little beauty lives in ./drivers/scsi/lpfc, the page is dated October 2026, and it answers to the name lpfc_mq_create_fb_init(9) — remember it fondly 🫶💜🎀
