hl_eq_fini(9)

💖 hl_eq_fini(9) — like, the Kernel API Manual era 💖

okay so bestie, welcome to the Kernel API Manual, section 9 — we're in the deep end of the pool now and honestly? it's giving main character energy. today's episode: hl_eq_fini, which is the "destroy event queue" girlie. she's the cleanup crew. the closer. the one who turns the lights off. 🎀

---

✨ NAME ✨

hl_eq_fini — destroy event queue 🧨

like, she destroys the event queue. that's the whole gig. no cap.

---

🌸 SYNOPSIS 🌸

void hl_eq_fini (struct hl_device *hdev , struct hl_eq *q );

yep that's it, that's the whole function. returns void, so she gives you nothing back — and honestly, respect. 💅

---

🦋 ARGUMENTS 🦋

• hdev — pointer to device structure 🫶 (your device, your main squeeze, the struct hl_device in question)
• q — pointer to eq structure 🌈 (the eq in question, i.e. the event queue we're about to send off)

two pointers, zero drama. she just needs to know which device and which queue.

---

🍓 DESCRIPTION 🍓

Free the event queue memory.

literally that's the description. free the memory. release it. let it go. 🕊️ the event queue memory gets freed and that is the entire vibe of this function — no extra steps, no surprises, no secret side quests.

ngl this is a short one, bestie — don't go looking for options, there are none, she has no flags, she is unbothered and unconfigurable. 💀
