init_msix(9)

💅 init_msix(9) — kernel API manual, but make it make sense

okay so bestie, welcome to the init_msix page from the Kernel API Manual. she's short, she's sweet, she does exactly one (1) thing, and honestly? iconic behaviour. let's get into it 🎀

---

✨ NAME ✨

init_msix — enable the msix and save the entries 💖

like yes, that's literally the whole personality: turn the msix on, stash the entries somewhere safe. slay.

---

✨ SYNOPSIS ✨

int init_msix (struct hinic_hwdev *hwdev );

that's the whole signature, no cap. she takes one (1) pointer and hands you back an int. 🫶

---

✨ ARGUMENTS ✨

• hwdev — the NIC HW device 🌸

that's it. that's the only thing you're passing in. one arg, main character energy, we respect it 👑

---

✨ DESCRIPTION ✨

okay so this is where it gets spicy (it does not get spicy, the manpage is genuinely a single line and I'm obsessed with the restraint):

• Return 0 — Success 🎉✨
• negative — Failure 😭💀

that's literally it. if you get 0, you ate. if you get something negative, the vibe check failed and you should probably go look at the code, fr fr.

ngl the original page gives you zero extra lore here — no caveats, no warnings, no "don't do this at 3am" notes. so I'm not gonna invent any. we keep it honest 🙈

🌈 the cute sign-off 🌈

this little page came to you courtesy of ./drivers/net/ethernet/huawei/..., dropped in October 2026, and stamped at the bottom as init_msix(9) — so if you ever forget where you read all this, it's that file, that month, that page. go be a kernel girlie, bestie 💅✨🍓🧚
