STRUCT SDW_STREAM_CONFIG(9)

✨ struct sdw_stream_config(9) ✨

okay so bestie, welcome to the <struct sdw_stream_config> glow-up 💅 this lil cutie lives in the Kernel API Manual and it's literally the master-or-slave stream configuration struct — like the outfit plan for your audio stream, no cap 🎀

---

🌸 NAME 🌸

struct sdw_stream_config — Master or Slave stream configuration 🦋

---

✨ SYNOPSIS ✨

struct sdw_stream_config {
    unsigned int frame_rate;
    unsigned int ch_count;
    unsigned int bps;
    enum sdw_data_direction direction;
    enum sdw_stream_type type;
 };

like, that's the whole fit. five fields. iconic. 👑

okay so let's meet the squad, one by one, fr fr:

• frame_rate — the audio frame rate of the stream, measured in Hz 🎵 (yes, Hz. she's precise.)
• ch_count — the channel count of the stream, aka how many channels are invited to the party 🌈
• bps — number of bits per audio sample, the literal bit budget per sample 💀
• direction — the data direction, aka which way the audio is flowing 🦋
• type — the stream type: PCM, PDM or BPT 👑 (three whole vibes, pick one)
