ice_free_cq_ring(9)

💅 ice_free_cq_ring(9) 💅

okay so this is a page straight out of the Kernel API Manual, and honestly? it's a whole little icon. it's ice_free_cq_ring, bestie — say it with me — and it's about freeing a control queue ring. that's the whole vibe. let's get into it ✨

---

🌸 NAME 🌸

ice_free_cq_ring — literally just: Free control queue ring. that's it. that's the function. no notes. 🎀

---

🦋 SYNOPSIS 🦋

void ice_free_cq_ring (struct ice_hw *hw , struct ice_ctl_q_ring *ring
);

so it returns void (nothing comes back, it's giving no thoughts head empty but in a purposeful way 💀) and it takes two args. that's the whole signature, copy it exactly, don't be cute with it.

---

✨ ARGUMENTS ✨

• hw — pointer to the hardware structure. yeah. the big one. the main character. 👑
• ring — pointer to the specific control queue ring you're about to free. your ring. your problem. 🫶

---

💖 DESCRIPTION 💖

so here's the thing, and this is important — this function assumes the posted buffers have already been cleaned and de-allocated. like, already done. beforehand. by you. 😭

it's not going to do that for you, it's not going to check, it's just going to assume. so if you rolled up here with buffers still hanging around, that's on you, and it's gonna be a bad time. do the cleanup first, then call this. periodt. 💅

⚠️ fr fr: this is an assumption, not a guard rail. clean and de-allocate your posted buffers before you call this, mkay?

okay and the little sign-off at the bottom of the page says this lil guy lives in ./drivers/net/ethernet/intel/ice, and it's dated October 2026. so yeah — that's the tea, that's the page, mwah 💋🌸 go free that ring bestie, and clean your buffers first, i'm begging 🙈💜
