amdtp_stream..._max_payload(9)

✨ amdtp_stream..._max_payload(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a lil function page and it's short but it matters, so let's get into it 🫶

---

🎀 NAME 🎀

amdtp_stream_get_max_payload — literally just "get the stream's packet size" 💖 that's the whole vibe, no cap.

---

🌸 SYNOPSIS 🌸

unsigned int amdtp_stream_get_max_payload (struct amdtp_stream *s );

yeah that's it. one arg, one unsigned int coming back at you ✨

---

🦋 ARGUMENTS 🦋

• s — the AMDTP stream 🎀 like, the actual stream object you're curious about. nothing else, just her 👑

---

💜 DESCRIPTION 💜

okay so here's the ONE thing you absolutely cannot fumble, bestie:

⚠️ This function must not be called before the stream has been configured with amdtp_stream_set_parameters.

like fr fr, do not call this before that. set your parameters first, then come ask about the packet size. it's giving "read the prerequisites before you run the code" energy 😭🙈
