ti_sci_put_one_xfer(9)

💅 ti_sci_put_one_xfer(9) — the Kernel API Manual, bestie edition

okay so you're in the kernel API manual, section 9, and today's main character is ti_sci_put_one_xfer — the "give the message back" girlie. Let's get into it 🎀

---

✨ NAME ✨

ti_sci_put_one_xfer — release a message. that's it, that's the whole job. she hands it back 🫶

---

🌸 SYNOPSIS 🌸

void ti_sci_put_one_xfer (struct ti_sci_xfers_info *minfo , struct ti_sci_xfer *xfer );

no return value, no drama, void and done ✨

---

🦋 ARGUMENTS 🦋

• minfo — the transfer info pointer. yep, the transfer-info situation, she needs it 💫
• xfer — the message that was reserved by ti_sci_get_one_xfer. like, the exact one you grabbed earlier. you can't just return a random one bestie 😭 it has to be the one you reserved 💅

---

👑 DESCRIPTION 👑

so what's actually happening under the hood? this function holds a spinlock so the internal data structures stay intact and nobody's stepping on anybody's toes. integrity is the vibe check here 🔥 no cap, the spinlock is the whole point — she locks, she does her thing, she keeps the internals safe 🧚

💖 SEE ALSO 💖

okay this list is long — like, main-character-long — but every single one of these sweeties belongs here, so here we go, no skipping 🙈
