lpfc_sli_hbqbuf_fill_hbqs(9)

💖 lpfc_sli_hbqbuf_fill_hbqs 💖

okay so bestie, we're in the Kernel API Manual today and this page is about lpfc_sli_hbqbuf_fill_hbqs(9) — yes that's a mouthful, no I will not be pronouncing it out loud. it's giving "driver internals" and honestly? we love her for it. ✨

---

🎀 NAME 🎀

lpfc_sli_hbqbuf_fill_hbqs — post more hbq buffers to HBQ. that's the whole vibe. more buffers, into the HBQ. slay.

---

🌸 SYNOPSIS 🌸

int lpfc_sli_hbqbuf_fill_hbqs (struct lpfc_hba *phba , uint32_t hbqno ,
uint32_t count );

---

🦋 ARGUMENTS 🦋

• phba — pointer to the HBA context object. your whole world lives in here tbh.
• hbqno — the HBQ number. which queue are we feeding, bestie?
• count — how many HBQ buffers you wanna post. the number. the amount. the quantity. 💅

---

✨ DESCRIPTION ✨

so this function gets called with no lock held — like, zero locks, none, we're free 💀 — and its whole job is to post more hbq buffers to the given HBQ.

and then it tells you how it went: the function returns the number of HBQ buffers successfully posted. no cap, that's the return value. if you posted some but not all, you get the number that actually made it. main character behavior fr fr.
