qed_ptt_acquire(9)

🦋 qed_ptt_acquire(9) — the kernel API manual, but make it make sense

okay bestie, so this is qed_ptt_acquire from the kernel API manual (man section 9, kernel devs only, we love that for us) — and honestly? it's a short one. we're gonna get through it together, no cap 💅

---

✨ NAME ✨

qed_ptt_acquire — Allocate a PTT window. that's the whole vibe. it gets you a PTT window, periodt 🎀

---

✨ SYNOPSIS ✨

struct qed_ptt * qed_ptt_acquire (struct qed_hwfn *p_hwfn );

literally one argument, one return, in and out, main character energy 🦋

---

✨ ARGUMENTS ✨

• p_hwfn — HW device data. that's your hardware function struct, the whole hardware situation, hand it over and let the function cook 🔥

---

✨ RETURN ✨

Returns a struct qed_ptt. that's it, that's the return, a struct qed_ptt and nothing else — no cap 🙈

---

✨ DESCRIPTION ✨

so the actual tea: you should be calling this at the entry point to the driver — like, specifically at the beginning of an exported function. that's the spot. that's where it goes. front of the line, first thing, before anything else gets to be cute 🌸

ngl this is the entire description. it's a two-sentence queen and she said what she said 👑
