lpfc_fcp_cpu_map_init(9)

💅 lpfc_fcp_cpu_map_init(9) — Kernel API Manual 🎀

okay so bestie, we're in the kernel API manual today and the star of the show is lpfc_fcp_cpu_map_init(9) ✨ (that's a section 9 page, kernel-API girlie, not your regular command-line situation). Buckle up, it's giving very specific and very slay.

---

🌸 NAME 🌸

lpfc_fcp_cpu_map_init — set the initial sr-iov virtual function enable 👑

no cap, that's literally what it does. it sets up the initial sr-iov virtual function enable situation. that's the whole vibe.

---

🦋 SYNOPSIS 🦋

int lpfc_fcp_cpu_map_init (struct lpfc_hba *phba , int val );

so it takes two things and it hands you back an int. simple. iconic. we love a clean signature 💖

---

✨ ARGUMENTS ✨

• phba — an lpfc_hba pointer. yes bestie, a pointer, it's pointing at your hba struct and it's the main character of this function 🫶
• val — the link speed value. that's it, that's the value, it's lowkey just a link speed value 🌈

---

💜 DESCRIPTION 💜

okay so here's the tea 🍓: if val is in a valid range [0-2], then it affinitizes the adapter's MSIX vectors. that's the whole story. no more, no less, don't @ me.

fr fr though — the range is [0-2]. if val is in there, MSIX vectors get affinitized. that's the deal 💅

---

🔥 RETURN 🔥

• zero if val saved 🎀
• -EINVAL — val out of range 😭💀

like, it's either "yay saved it" (zero) or "girl that value is not in [0-2]" (-EINVAL). binary queen behavior.
