💅 _hardware_enqueue(9) 💅

So this is a page from the Kernel API Manual, bestie — section 9, kernel routines. Buckle up 🎀

🌸 NAME 🌸

_hardware_enqueue — literally configures a request at the hardware level. That's the whole vibe check ✨

---

🦋 SYNOPSIS 🦋

int _hardware_enqueue (struct ci_hw_ep *hwep , struct ci_hw_req *hwreq
);

Yes bestie, it returns an int. Keep reading 👀

💖 ARGUMENTS 💖

• hwep — the endpoint. That's it, that's the whole description 🫶
• hwreq — the request. Also exactly what it sounds like 💅

⭐ DESCRIPTION ⭐

This function returns an error code. And honestly? That's all the manual gives us 😭 No lore, no backstory, no extra details — just "returns an error code," periodt. Take it and go, icon 👑
