lpfc_config_msi(9)

💅 lpfc_config_msi

okay so bestie, welcome to the Kernel API Manual ✨ — yes we're reading kernel docs together, this is our bonding era 🫶. Today's main character is lpfc_config_msi, and no cap, it's lowkey iconic in a super specific way.

---

✨ NAME ✨

lpfc_config_msi — prepare a mailbox command for configuring msi-x 🎀

---

🌸 SYNOPSIS 🌸

int lpfc_config_msi (struct lpfc_hba *phba , LPFC_MBOXQ_t *pmb );

like, that's the whole vibe right there 💫

---

🦋 ARGUMENTS 🦋

• phba — pointer to lpfc hba data structure 💖 (it's the HBA, it's giving main character energy)
• pmb — pointer to the driver internal queue element for mailbox command 📬 (the little envelope that carries your command, iykyk)

---

🔥 DESCRIPTION 🔥

So the configure MSI-X mailbox command is literally there to configure the HBA's SLI-3 MSI-X multi-message interrupt vector association to interrupt attention conditions ✨. That's the whole job. It ate and left no crumbs 💅.

Return codes:

• 0 — Success 👑
• -EINVAL — Failure 💀

fr fr, that's the entire success/failure situation — 0 good, -EINVAL bad. memorize it bestie 🧚
