i40e_alloc_mapped_page(9)

✨ i40e_alloc_mapped_page — the Kernel API Manual tea 💅

okay so bestie, this one's from the Kernel API Manual and it's literally called i40e_alloc_mapped_page(9) — and yeah the whole vibe is "recycle or make a new page" 🎀 like it's a sustainable little king, periodt.

---

🌸 NAME 🌸

i40e_alloc_mapped_page — recycle or make a new page 🦋

---

✨ SYNOPSIS ✨

bool i40e_alloc_mapped_page (struct i40e_ring *rx_ring , struct
i40e_rx_buffer *bi );

no cap, that's the whole signature — she's short and she knows it 😭

---

🫶 ARGUMENTS 🫶

• rx_ring — the ring to use. that's your ring bestie, the one you're working in 💫
• bi — the rx_buffer struct to modify. you're editing her, respectfully 🙈

---

👑 DESCRIPTION 👑

Returns true if the page was successfully allocated or reused 💖

that's it, that's the tea — she either recycles or she makes a fresh one, and either way you get true when it works. iconic behavior ngl ⭐
