💖 ti_sci_rx_callback (9) — Kernel API Manual 💖

okay so bestie, you found the man page for ti_sci_rx_callback — it's the mailbox client callback that handles incoming messages, and honestly it's giving "small function, big job" energy 🎀

✨ NAME ✨

ti_sci_rx_callback — the mailbox client callback for receive messages 🦋

🌸 SYNOPSIS 🌸

void ti_sci_rx_callback (struct mbox_client *cl , void *m );

yeah, that's the whole signature. two args, no return value, very demure, very mindful 💅

🎀 ARGUMENTS 🎀

  • cl — the client pointer 🫶
  • m — the mailbox message itself, like the actual payload that just showed up

👑 DESCRIPTION 👑

So what it does: it takes one received message and processes it into the appropriate transfer information, then signals that the transfer is complete ✨ that's it, that's the whole vibe. a message comes in, it gets sorted into the right xfer, and the completion gets signalled. lowkey iconic for how much it does with so little 😌

⚠️ NOTE ⚠️

bestie listen to me. this function gets invoked in IRQ context — interrupt context, okay?? so it needs to be as optimal as possible. no cap. do NOT be doing slow, sleepy, heavy lifting in here 💀 keep it lean, keep it fast, keep it interrupt-friendly 🔥

🌈 SEE ALSO 🌈

everything else hanging out in the kernel file ./drivers/firmware/ti_sci.c and its whole friend group 🧚:

that's the whole page bestie, go be optimal in IRQ context 💜

sign-off szn ✨ this lil beauty lives under ./drivers/firmware and the date on it is October 2026 — yeah, future-coded, we know 🦋
