STRUCT TI_SCI_XFER(9)

📦 version 7.3.1, in nixpkgs unstable

💅 struct ti_sci_xfer(9) — Kernel API Manual, bestie 🎀

okay so this page is straight out of the Kernel API Manual, section 9, and it's all about one lil struct. yes it's a whole manual page for a struct. that's the vibe. let's get into it ✨

🌸 NAME 🌸

struct ti_sci_xfer — ngl, this one's literally the Structure representing a message flow. that's the whole job. that's what it does 💫

🦋 SYNOPSIS 🦋

here's the whole thing, character for character, no cap:

struct ti_sci_xfer {
    struct ti_msgmgr_message tx_message;
    u8 rx_len;
    u8 *xfer_buf;
    struct completion done;
 };

four members. four. it's giving "small but mighty" energy and honestly? obsessed 🫶

👑 Members 👑

okay so let's meet the cast 💖

  • tx_message — the Transmit message. this is the actual thing going out the door, she's the main character here ✨
  • rx_len — the Receive message length. how much came back. a u8. tiny but load-bearing 🧚
  • xfer_buf — a Preallocated buffer to store receive message. and here's the cute part, bestie: since we work with the request-ACK protocol, we can reuse the same buffer for the rx path as we use for the tx path. one buffer, two jobs. iconic efficiency behavior 💅🔥
  • done — the completion event. it's the little "we're so back" notification when the flow finishes ⭐
lowkey the xfer_buf thing is the whole personality of this struct — request-ACK means the buffer pulls double duty and saves everybody a malloc. slay 🎀

🌈 SEE ALSO 🌈

okay this is the part where the page goes absolutely feral with cross-references, but every single one is a real one and i'm listing them all fr fr 💀

like i said. feral. but complete 🌸💀

and that's the page, bestie!! 🎀 this lil cutie lives in ./drivers/firmware and the page itself is dated October 2026 — so yeah, she's from the future, we stan a forward-looking struct 👑✨ bye bye 🦋💖
