qed_mcp_halt(9)

💅 qed_mcp_halt(9) — bestie, we're halting the MCP ✨

okay so real talk, this one is from the Kernel API Manual, section 9 of the man pages, and it's short and sweet — literally one job. Let's get into it 🫶

---

🌸 NAME 🌸

qed_mcp_halt — halt the MCP. that's it. that's the whole vibe. no cap 💀

---

✨ SYNOPSIS ✨

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

she takes two pointers and returns an int, periodt 👑

---

🎀 ARGUMENTS 🎀

• p_hwfn — the HW device data. this is the hardware function struct, the main character of this whole operation 🌈
• p_ptt — P_ptt. yeah, that's literally what the docs say. P_ptt. iykyk 🙈

---

⭐ RETURN ⭐

0 upon success. that's the whole return contract — zero means we ate and left no crumbs 🔥

🦋 SEE ALSO 🦋

first up, the kernel file, like the actual source of truth: ./drivers/net/ethernet/qlogic/qed/qed_mcp.h 💖

and then the whole friend group, all of these are also (9) man pages so go say hi:

lowkey that's a whole friend group but every single one of them is a (9) man page, so the link is: they're all siblings in the same kernel section. slay 💅
