ishtp_cl_connect_to_fw(9)

💖 ishtp_cl_connect_to_fw 💖

okay so bestie, welcome to the ishtp_cl_connect_to_fw page — it lives in section 9 of the Kernel API Manual, and it's genuinely one of the most "let me just text the firmware real quick" functions in the whole Intel ISH-TP client family. ✨

---

🌸 NAME 🌸

ishtp_cl_connect_to_fw — literally just sends a connect request to the firmware. that's it. that's the whole vibe. 🎀

---

🦋 SYNOPSIS 🦋

int ishtp_cl_connect_to_fw (struct ishtp_cl *cl );

---

✨ ARGUMENTS ✨

• cl — the client device instance 👑 (your little main character struct, the one we're sending the connect request for)

---

💅 DESCRIPTION 💅

so here's what's happening, no cap: you send a connect request to the firmware, and then you wait for the firmware to respond. like, you're not just yeeting it into the void and walking away — you're sitting there with your phone on loud, refreshing, waiting for that reply. 😭

and if the firmware comes back with a successful connection response? oh it's over, it slays: the client state gets changed to ISHTP_CL_CONNECTED 💖, and the client gets bound to the related firmware client_id. iconic. periodt.

---

🔥 RETURN 🔥

• 0 means success, bestie 🫶
• anything else is an error code, so like... vibe check failed, something went wrong 💀
