qed_mcp_reset(9)

💅 qed_mcp_reset(9) — a Kernel API Manual moment 🎀

okay so this is a page from the Kernel API Manual and bestie it's short but it slaps. it's about qed_mcp_reset, which — spoiler — resets the MCP using a mailbox command. that's it. that's the whole vibe. ✨

---

🌸 NAME 🌸

qed_mcp_reset — reset the MCP using a mailbox command, no cap.

---

✨ SYNOPSIS ✨

int qed_mcp_reset (struct qed_hwfn *p_hwfn , struct qed_ptt *p_ptt );

literally just call it like that. two args, one int back. clean. 🫶

---

🦋 ARGUMENTS 🦋

• p_hwfn — HW device data. it's the hardware function handle, the main character of the struct world 👑
• p_ptt — P_ptt. yes that's the whole description, i'm not making this up 😭

---

💜 RETURN 💜

0 upon success. that's the only documented outcome on this page, so if you get a 0 you ate, periodt. 🔥

ngl this page is basically a one-liner with a huge friend list, and honestly? iconic. reset the MCP, get a 0, go touch some grass. 💖
