lpfc_config_async(9)

💖 lpfc_config_async(9) — the girlies' guide to the Kernel API Manual ✨

okay so welcome to lpfc_config_async, bestie!! this one lives in the Kernel API Manual and it's lowkey a little setup goblin — it doesn't do the thing, it just gets the mailbox command ready to do the thing. we love a prep queen 🎀

---

✨ NAME ✨

lpfc_config_async — prepare a mailbox command for enabling HBA async event. that's it, that's the whole vibe 💅

---

🦋 SYNOPSIS 🦋

void lpfc_config_async (struct lpfc_hba * phba , LPFC_MBOXQ_t * pmb ,
uint32_t ring );

literally three args, no return value (it's void, so don't go looking for one, she's not giving 🙈)

---

🌸 ARGUMENTS 🌸

• phba — pointer to lpfc hba data structure. your HBA's whole personality lives here 💜
• pmb — pointer to the driver internal queue element for mailbox command. this is the little envelope we're stuffing 📬
• ring — ring number for the asynchronous event to be configured. pick your ring, bestie, that's where the events are gonna get posted ✨

---

💀 DESCRIPTION 💀

so the asynchronous event enable mailbox command is the one that enables the asynchronous event posting via the ASYNC_STATUS_CN IOCB response — and it also specifies the default ring to which events are posted. iykyk 👑

this routine prepares the mailbox command for enabling HBA asynchronous event support on a IOCB ring. no cap, that's the whole job — she preps, she doesn't fire 🫶

ngl, if you're enabling async events, make sure your ring is actually a ring you meant to pick — she takes the number at face value, no vibe check on your behalf 💀

alright bestie, that's the page!! this one came from <pink>./drivers/scsi/lpfc</pink>, dated October 2026, and it's filed under lpfc_config_async(9) — stan a kernel manpage that knows exactly what she is ✨👑💅
