✨ amdtp_stream_set_parameters(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this is the page for amdtp_stream_set_parameters, and it's literally the "get your stream set up before you press play" function. no notes, it does one job and it ate. 🎀

---

🌸 NAME 🌸

amdtp_stream_set_parameters — set stream parameters, periodt. that's the whole vibe.

---

🦋 SYNOPSIS 🦋

int amdtp_stream_set_parameters (struct amdtp_stream *s , unsigned int
rate , unsigned int data_block_quadlets , unsigned int
pcm_frame_multiplier );

like look at her. four arguments, one int coming back at you. main character energy fr fr 🔥

---

💖 ARGUMENTS 💖

• s — the AMDTP stream you're configuring. this is the stream, the one you're about to glow up ✨
• rate — the sample rate. yes, the actual sample rate, no cap 🎵
• data_block_quadlets — the size of a data block, measured in quadlet units. quadlets!! iconic unit name ngl 🧚
• pcm_frame_multiplier — the multiplier used to compute the number of PCM frames from the number of AMDTP events. it's giving "math but make it cute" 🍓

---

👑 DESCRIPTION 👑

okay this is the important bit, so listen up bestie 🫶

the parameters must be set before the stream is started, and they must not be changed while the stream is running.

⚠️ like, do not try to swap these mid-flight. set them up first, then start the stream. that's the order. no exceptions, no vibe check needed 💀
