qed_init_pf_wfq(9)

💅 qed_init_pf_wfq — a Kernel API Manual moment (section 9, bestie)

Okay so picture this: you're deep in the kernel API manual, section 9, and you stumble onto qed_init_pf_wfq. That's the whole vibe. This little icon does exactly one thing and does it slay: it initializes the WFQ weight of the specified PF. That's it. That's the function. 🎀

---

✨ SYNOPSIS ✨

int qed_init_pf_wfq (struct qed_hwfn *p_hwfn , struct qed_ptt *p_ptt ,
u8 pf_id , u16 pf_wfq );

No cap, that's the signature, copied character for character because I respect you. 🫶

🌸 ARGUMENTS 🌸

• p_hwfn — the HW device data. Like, the whole hardware situation, wrapped up in a struct. Main character energy honestly.
• p_ptt — the Ptt window used for writing the registers. That's your little doorway into register-land, iykyk. 🚪✨
• pf_id — the PF ID. Which PF? This one. 💅
• pf_wfq — the WFQ weight. Must be non-zero. Not "should be", not "ideally" — must. Zero is not invited to this party. 🙈

---

⭐ RETURN ⭐

• 0 on success — slay, you ate, periodt. 👑
• -1 on error — it's giving struggle, but at least it's honest. 😭

🫶 Real talk though: pf_wfq being non-zero isn't a suggestion, it's a requirement. Respect the constraint, bestie. 💖
