qed_hw_err_notify(9)

💅 qed_hw_err_notify(9) — the Kernel API Manual, bestie edition

okay so real talk, this page is from the Kernel API Manual, section 9, and it's about qed_hw_err_notify. It's short, it's sweet, it's giving "one job and it does it." Let's get into it 🫶

---

✨ NAME ✨

qed_hw_err_notify — the function that tells the upper layer driver and the management FW that a HW error happened. Like, "hey besties, hardware said no 💀" — that's the whole vibe.

---

🌸 SYNOPSIS 🌸

void  __cold qed_hw_err_notify (struct qed_hwfn *p_hwfn , struct qed_ptt
*p_ptt , enum qed_hw_err_type err_type , const char *fmt , ... );

---

🎀 ARGUMENTS 🎀

• p_hwfn — the HW device data. The main character's profile, basically 👑
• p_ptt — P_ptt. That's it, that's the description, no notes 💀
• err_type — the error type. Which flavor of oops we're dealing with.
• fmt — the debug data buffer that gets sent to the MFW. Lowkey the receipts 📩
• ... — the buffer format args. The little extras that go with fmt.

---

🦋 DESCRIPTION 🦋

Returns void. That's the entire description, no cap. Nothing to return, nothing to stress about, it just does the notify thing and dips ✨
