ice_set_q_vector_intrl(9)

💖 ice_set_q_vector_intrl(9) — the kernel API manual, but make it cute 🎀

okay so bestie, welcome to the ice_set_q_vector_intrl(9) page from the Kernel API Manual ✨ this one's all about setting up interrupt rate limiting, and honestly? it's giving "small function, big responsibilities" energy. let's get into it 💅

---

🌸 NAME 🌸

ice_set_q_vector_intrl — set up interrupt rate limiting ⏱️✨

---

🦋 SYNOPSIS 🦋

void ice_set_q_vector_intrl (struct ice_q_vector *q_vector );

like, that's the whole signature. short king 👑 no cap.

---

🍓 ARGUMENTS 🍓

• q_vector — the vector to be configured 💖 this is the one getting the glow-up, so be nice to it.

---

✨ DESCRIPTION ✨

okay so here's the tea ☕ — interrupt rate limiting is local to the vector, not per-queue. which means we literally have to detect if either ring container has dynamic moderation enabled, because that's what decides what we set the interrupt rate limit to via the INTRL settings. iykyk 🧚

and in the case that dynamic moderation is disabled on both of them? we write the value with the cached setting, so the INTRL register matches the user visible value. periodt. that's the whole vibe check 💀✅
