scmi_xfer_raw_get(9)

✨ NAME ✨

okay bestie, welcome to scmi_xfer_raw_get(9) from the Kernel API Manual — the page about grabbing a bare free xfer from the TX channel. This is your group-chat cheat sheet, but make no mistake: every pointer, argument, return value, and SEE ALSO reference is staying. 💅✨

scmi_xfer_raw_get — helper to get a bare free xfer from the TX channel. That’s the name, that’s the job, and yes it’s giving “bare minimum but make it firmware.” 🎀

---

🌸 SYNOPSIS 🌸

Here’s the exact signature, bestie — don’t let the line wrap scare you:

struct scmi_xfer * scmi_xfer_raw_get (const struct scmi_handle *handle
);

---

🎀 ARGUMENTS 🎀

Only one argument, and she’s important:

• handle — Pointer to SCMI entity handle. That’s it. That’s the whole argument. 🫶

---

💅 DESCRIPTION 💅

Note that xfer is taken from the TX channel structures. Lowkey the whole description is that one note, and we respect it. 💖

---

🦋 RETURN 🦋

A valid xfer on Success, or an error-pointer otherwise. So on success you get a valid xfer; otherwise it’s error-pointer o’clock. 😭💅
