💅 igbvf_request_msix(9) 💅

okay so this is a page from the Kernel API Manual (yes, the big one, the iconic one) and we're talking about igbvf_request_msix today. Buckle up bestie 🎀

---

✨ NAME ✨

igbvf_request_msix — literally just Initializes MSI-X interrupts. that's the whole vibe. ✨

---

🌸 SYNOPSIS 🌸

int igbvf_request_msix (struct igbvf_adapter *adapter );

copy it exactly, no cap, not me being dramatic about the spacing — it's giving "paste it verbatim" energy 💅

---

🦋 ARGUMENTS 🦋

• adapter — the board private structure. that's it, that's the whole argument. she's low maintenance, we love her 🫶

---

💖 DESCRIPTION 💖

so igbvf_request_msix allocates MSI-X vectors and requests interrupts from the kernel. two jobs, one function, main character energy fr fr 👑

like, she goes and gets the vectors, then she asks the kernel super nicely for the interrupts. basically the wingman of the igbvf driver 😭✨

so yeah, that's the page 🧚 this little beauty is from ./drivers/net/ethernet/intel/i... (yes it's truncated in the footer, don't come for me, that's just how she was printed 😭) and it's dated October 2026, version and all. go read igbvf_request_msix(9), stay hydrated, and remember: MSI-X vectors don't allocate themselves, bestie. periodt. 💅👑⭐
