ibmvmc_ioctl_requestvmc(9)

💅 ibmvmc_ioctl_requestvmc — like, the IOCTL Request VMC one

okay so bestie, we're in the Kernel API Manual today, and the star of the show is ibmvmc_ioctl_requestvmc(9). Yes it's a mouthful. Yes it's iconic. Let's go ✨

---

🌸 NAME 🌸

ibmvmc_ioctl_requestvmc — literally IOCTL Request VMC. That's it, that's the whole name, no notes 💅

---

🦋 SYNOPSIS 🦋

long ibmvmc_ioctl_requestvmc (struct ibmvmc_file_session *session , u32
__user *ret_vmc_index );

look at that signature. so long. so long. main character energy fr fr 🎀

---

🎀 ARGUMENTS 🎀

• session — a ibmvmc_file_session struct, bestie. that's the vibe. that's what you pass in 👑
• ret_vmc_index — the VMC Index. that's the whole description, and honestly? it ate. keep it 🫶

ngl the argument docs are short and sweet here — don't come for me, I'm just the messenger 💀

---

⭐ RETURN ⭐

• 0 — Success 💖
• Non-zero — Failure 😭

that's the entire contract. zero and slay, or not-zero and cry. no in between 🔥

and that's the page!! this lil beauty lives in ./drivers/misc and the version stamp on it says October 2026 — and if you ever need to cite it, the name to drop is ibmvmc_ioctl_requestvmc(9) 🧚‍♀️ mwah, go read the kernel source, periodt 💖
