ti_sci_cmd_rm_psil_pair(9)

✨ ti_sci_cmd_rm_psil_pair ✨

okay bestie, welcome to the Kernel API Manual 💖 this one's a lil kernel function called ti_sci_cmd_rm_psil_pair(9) and ngl it's giving "tiny signature, very specific job" energy. let's get into it 🎀

---

🌸 NAME 🌸

ti_sci_cmd_rm_psil_pair — literally pairs a PSI-L source thread to a destination thread 🦋 (yes, that's what the manpage says, and we are not editorializing, bestie, we report the facts 💅)

---

⭐ SYNOPSIS ⭐

int ti_sci_cmd_rm_psil_pair (const struct ti_sci_handle *handle , u32
nav_id , u32 src_thread , u32 dst_thread );

look at her. four args, one int back. clean. iconic. 👑

---

💜 ARGUMENTS 💜

• handle — a pointer to the TI SCI handle 🫶 like, the whole VIP pass for this call.
• nav_id — the device ID of the Navigator Subsystem that should be used for pairing ✨ this is the one doing the pairing, so be nice to it.
• src_thread — source PSI-L thread ID 🌈
• dst_thread — destination PSI-L thread ID 🌸

---

🔥 RETURN 🔥

returns 0 if everything went well, otherwise it hands you back the appropriate error value 😭 so like… check it. fr fr.
