qed_rd(9)

🌸 qed_rd(9) — Kernel API Manual 🌸

Okay bestie, welcome to the <pink>qed_rd</pink> page, straight out of the Kernel API Manual 💅 this one's a tiny lil function with main character energy, so let's get into it.

---

✨ NAME ✨

qed_rd — read a value from BAR using the given ptt 🫶 that's literally the whole job, no cap.

---

✨ SYNOPSIS ✨

u32 qed_rd (struct qed_hwfn *p_hwfn , struct qed_ptt *p_ptt , u32
hw_addr );

Not me just vibing with a u32 return type while the RETURN section says void — iconic chaos, but that's the manpage's business, not mine 😭

---

✨ ARGUMENTS ✨

• p_hwfn — the HW device data 💖 your hardware's whole personality lives in here.
• p_ptt — the P_ptt. That's it, that's the description, no elaboration given, and honestly? Respect 🙈
• hw_addr — the HW address ✨ the exact spot you're reading from.

---

✨ RETURN ✨

Void. That's the whole section. Short, sweet, ate and left no crumbs 💀

---
