lpfc_sli_hbq_to_firmware_s3(9)

💖 lpfc_sli_hbq_to_firmware_s3(9) 💖

bestie, welcome to the Kernel API Manual ✨ this little page is all about one function that ships an HBQ buffer over to SLI3 firmware, and honestly? it's giving "small but crucial middle-manager" energy. let's get into it 🫶

---

🌸 NAME 🌸

lpfc_sli_hbq_to_firmware_s3 — post the hbq buffer to SLI3 firmware 💅

---

⭐ SYNOPSIS ⭐

int lpfc_sli_hbq_to_firmware_s3 (struct lpfc_hba *phba , uint32_t hbqno
, struct hbq_dmabuf *hbq_buf );

---

🎀 ARGUMENTS 🎀

• phba — pointer to the HBA context object. the whole context situation, iykyk.
• hbqno — the HBQ number. just the number, that's it.
• hbq_buf — pointer to the HBQ buffer. the star of the show 🦋

---

✨ DESCRIPTION ✨

okay so here's the vibe: this function gets called with the hbalock held (hbalock stays exactly that, don't @ me) and its whole job is posting an hbq buffer to the firmware.

the way it works is, if it finds an empty slot in the HBQ, it posts the buffer AND drops it onto the hbq_buffer_list. cute, efficient, no notes 💅

return value tea ☕: it returns zero if it successfully posted the buffer, otherwise it returns an error. so like, zero = slay, anything else = check yourself 🫶

note bestie: it says if it finds an empty slot — so that empty-slot situation is a real condition to think about, fr fr.

okay that's the whole page, bestie, go forth and post those buffers 💅✨

this cutie came to you straight out of ./drivers/scsi/lpfc, dated October 2026, and it lives at lpfc_sli_hbq_to_firmware_s3(9) — periodt 🎀🦋💖
