qed_get_igu_free_sb(9)

🎀 qed_get_igu_free_sb(9) 🎀

okay bestie, welcome to the Kernel API Manual page for qed_get_igu_free_sb(9). This one is short, sweet, and honestly kind of iconic: it's all about grabbing an unused valid SB pointer. Let's get into it 💅✨

---

🌸 NAME 🌸

qed_get_igu_free_sb — the goal is literally to return a pointer to an unused valid SB. That's the whole assignment, no cap. 🫶

---

✨ SYNOPSIS ✨

struct qed_igu_block * qed_get_igu_free_sb (struct qed_hwfn *p_hwfn ,
       bool b_is_pf );

---

💖 ARGUMENTS 💖

• p_hwfn — HW device data. That's the hardware bestie being passed in. 🛠️
• b_is_pf — True iff we want a SB belonging to a PF. Yes, iff — it's giving precise technical language, we respect it. 💅

---

🦋 RETURN 🦋

It points to an igu_block, or NULL if none is available. Short, clear, and lowkey dramatic if you get that NULL 😭✨
