💅 scmi_xfer_raw_wait_for_message_response — Kernel API Manual 🎀

okay so bestie, welcome to the scmi_xfer_r...age_response(9) page ✨ (yes the title got abbreviated by the manpage machinery, we don't question it, we accept her 💀). This is a Kernel API Manual moment and honestly? it's giving "small helper, huge responsibility" energy. Let's get into it 🫶

---

🌸 NAME 🌸

scmi_xfer_raw_wait_for_message_response — an helper to wait for a message reply to an xfer raw request on a specific channel for the required timeout 💖

Like literally that's her whole job. She waits. On a specific channel. For the required timeout. Iconic behavior, no notes 👑

---

✨ SYNOPSIS ✨

int scmi_xfer_raw_wait_for_message_response (struct scmi_chan_info
*cinfo , struct scmi_xfer *xfer , unsigned int timeout_ms );

three args, one int coming back at you, that's the whole vibe check 🦋

---

💜 ARGUMENTS 💜

• cinfo — SCMI channel info 💫 this is the channel bestie, the one she's specifically waiting on, keep your eyes on her
• xfer — Reference to the transfer being waited for 🌈 like, the actual thing you're sitting around hoping replies to you
• timeout_ms — The maximum timeout in milliseconds ⏰ and yeah — maximum. she will not wait forever, she has boundaries

---

🎀 RETURN 🎀

0 on Success, error otherwise 🙈

that's it. that's the whole return section. zero means slay, anything else means something went sideways and you should go look at it fr fr

ngl that's a whole ecosystem of functions right there — read a couple, they all hang out in the same driver file, it's giving one big friend group 💀
