e1000_request_msix(9)

💖 e1000_request_msix 💖

okay so bestie, welcome to the e1000_request_msix(9) page — it's a Kernel API Manual situation, and honestly it's a short one but it's important, so let's get into it 🎀

---

✨ NAME ✨

e1000_request_msix — literally the function that initializes MSI-X interrupts, no cap 💅

---

🌸 SYNOPSIS 🌸

int e1000_request_msix (struct e1000_adapter *adapter );

like… that's the whole signature. she's simple. she's iconic. she takes one (1) argument and returns an int 🫶

---

🦋 ARGUMENTS 🦋

• adapter — the board private structure 💜 that's it, that's the whole description. it's giving "minimalist queen" but fr fr that's what the manpage says.

---

⭐ DESCRIPTION ⭐

so what does she do? e1000_request_msix allocates MSI-X vectors and then requests interrupts from the kernel. that's the whole vibe check. two jobs, both slaying 🔥

think of it as the moment the driver walks up to the kernel like "hi bestie, can I have some MSI-X vectors please, and also can you hook me up with interrupts" and the kernel is like "say less" ✨

no extra lore here, babe — the manpage keeps it short and so do we. everything above is all the description you're getting 🎀

👑 SEE ALSO 👑

okay this is the part where she lists everyone in her contacts 😭 like genuinely the whole friend group, plus the kernel file she lives in:
