iavf_acquire_msix_vectors(9)

🌸 iavf_acquire_msix_vectors(9) — a Kernel API Manual moment 🌸

okay so bestie, gather round, because this one is from the Kernel API Manual and it's about that interrupt-vector life. Yes, the whole page is literally called iavf_acquire_msix_vectors(9) — say it with your chest 💅

---

✨ NAME ✨

iavf_acquire_msix_vectors — Setup the MSIX capability 🎀

like, that's the whole vibe. it sets up the capability. that's it. slay.

---

🦋 SYNOPSIS 🦋

int iavf_acquire_msix_vectors (struct iavf_adapter *adapter , int
vectors );

not me writing out the whole signature with the line break exactly like the original did 😭 yes, the * hugs adapter, we don't question it, we respect it.

---

💜 ARGUMENTS 💜

• adapter — board private structure. this is your main character 💫 the struct the whole driver keeps its business in.
• vectors — number of vectors to request. like, how many you want. that's the number. go off 🔥

---

🌈 DESCRIPTION 🌈

Work with the OS to set up the MSIX vectors needed. 🫶

that's genuinely the whole description — you hang out with the OS, you two figure out the MSIX vectors, and everybody moves on. teamwork, baby ✨

Returns 0 on success, negative on failure ⭐ so like, zero is the good ending, anything negative is the "we don't talk about it" ending 💀

ngl the return value is the only drama here: 0 = slay, negative = not slay. no in-between.
