lpfc_build_hbq_profile2(9)

💖 lpfc_build_hbq_profile2 — the lpfc_build_hbq_profile2(9) kernel API page, but make it make sense ✨

okay so bestie, we're in the kernel API manual today (yes, the Kernel API Manual one) and this little function is genuinely so specific and I love that for her 💅

---

🌸 NAME 🌸

lpfc_build_hbq_profile2 — set up the HBQ Selection Profile 2 🎀

---

✨ SYNOPSIS ✨

void lpfc_build_hbq_profile2 (struct config_hbq_var *hbqmb , struct
       lpfc_hbq_init *hbq_desc );

like, it returns void, it takes two pointers, and it's giving "I do one thing and I do it well" energy 👑

---

🦋 ARGUMENTS 🦋

• hbqmb — pointer to the HBQ configuration data structure in the mailbox command. think of it as the lil clipboard she's gonna write on 📋
• hbq_desc — pointer to the HBQ selection profile descriptor. the blueprint, the vibe reference, the inspo board 🎨

---

💜 DESCRIPTION 💜

so the Host Buffer Queue (HBQ) Selection Profile 2 works like this, bestie: it specifies that the HBA tests the incoming frames' R_CTL/TYPE fields with words 10:15, and then it performs the Sequence Length Test using the fields that live in the Selection Profile 2 extension in words 20:31. two little field-ranges, two very specific jobs, no cap 🫶

that's it. that's the whole personality. and honestly? iconic ⭐

okay that's the whole page, mwah 💋 this came from ./drivers/scsi/lpfc and the manual says October 2026, lpfc_build_hbq_profile2(9) — so like, future-dated and flawless, main character energy fr fr 👑💖
