wx_set_ivar(9)

🌸 wx_set_ivar 🌸

okay bestie, welcome to the Kernel API Manual, section 9 — this one's wx_set_ivar(9), and it's literally the little function that tells your IVAR registers which interrupt cause goes to which vector. matchmaking, but for interrupts 💅

---

✨ NAME ✨

wx_set_ivar — set the IVAR registers, mapping interrupt causes to vectors

like... it's a matchmaker. interrupt cause goes here, vector goes there, and wx_set_ivar makes the introduction 🫶

---

✨ SYNOPSIS ✨

void wx_set_ivar (struct wx *wx , s8 direction , u16 queue , u16 msix_vector );

no cap, that's the whole signature. keep it exactly like that ✨

---

✨ ARGUMENTS ✨

• wx — pointer to wx struct. yes bestie, the struct itself, hand it over 🎀
• direction — 0 for Rx, 1 for Tx, -1 for other causes. three moods, pick one 🌈
• queue — queue to map the corresponding interrupt to. this is the queue getting its little interrupt bestie assigned 💖
• msix_vector — the vector to map to the corresponding queue. the other half of the pairing 👑
