qed_mcp_resume(9)

💅 qed_mcp_resume — the manual page, but make it make sense

Okay so bestie, you found a section 9 page — that's the Kernel API Manual corner of the world, where the kernel devs document their functions for each other. This one is called qed_mcp_resume and honestly? The whole job is in the name. Let's get into it. ✨

---

🌸 NAME 🌸

qed_mcp_resume — wake up the MCP. That's it. That's the whole vibe. It's giving "rise and grind" but for hardware. 💅

---

🎀 SYNOPSIS 🎀

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

Two pointers in, one int out. Clean. Minimal. Iconic. 👑

---

🦋 ARGUMENTS 🦋

• p_hwfn — HW device data. Like, the hardware function struct — the whole device situation lives in here. 🫶
• p_ptt — P_ptt. That's literally what the page says, and I'm not gonna gaslight you by making stuff up — the docs keep it short and sweet on this one. 🙈

---

⭐ RETURN ⭐

0 upon success. That's the whole return contract, no cap. 🎯
