idpf_vport_intr_req_irq(9)

💅 idpf_vport_intr_req_irq — kernel API manual, but make it make sense

okay so bestie, this one's from the Kernel API Manual (that's the manual name, iykyk), and it's about the idpf driver — Intel's virtual port situation. Buckle up, it's short and sweet, we love a low-effort icon ✨

---

🎀 NAME 🎀

idpf_vport_intr_req_irq — literally just: get MSI-X vectors from the OS for the vport. that's the whole job. girl is a middleman and she's thriving 💅

---

✨ SYNOPSIS ✨

int idpf_vport_intr_req_irq (struct idpf_vport *vport , struct
idpf_q_vec_rsrc *rsrc );

so she takes two things and hands you back an int. no cap, that's it 🫶

---

🌸 ARGUMENTS 🌸

• vport — the main vport structure. the leading lady, the main character, the whole point 👑
• rsrc — pointer to queue and vector resources. this is where the queues and vectors live, and yeah, we're passing a pointer to it 🦋

---

⭐ RETURN ⭐

• 0 on success — slay, the OS said yes 💖
• negative on failure — not slay, the OS said no, and it's giving error vibes 😭

🌈 SEE ALSO 🌈

okay this section is long, the original really said "here's the entire driver, go read it" and honestly? iconic. first off, the file herself:

Kernel file ./drivers/net/ethernet/intel/idpf/idpf_txrx.c
