STRUCT SDW_PORT_PARAMS(9)

💅 struct sdw_port_params(9) — like, the Data Port parameters struct, bestie ✨

okay so real talk, this is a page out of the Kernel API Manual, and it's all about struct sdw_port_params — no cap, it's the little struct that tells a SoundWire Data Port how to behave 🎀

---

🌸 NAME 🌸

struct sdw_port_params — Data Port parameters. that's it, that's the vibe 🦋

---

✨ SYNOPSIS ✨

here's the struct in all its glory, copied exactly, don't touch a single character:

struct sdw_port_params {
    unsigned int num;
    unsigned int bps;
    unsigned int flow_mode;
    unsigned int data_mode;
 };

---

🫶 Members 🫶

• num — the Port number. which port are we talking about, queen 👑
• bps — the Word length of the Port. yes bestie, the word length 📏
• flow_mode — the Port Data flow mode. how the data flows, periodt 🌊
• data_mode — Test modes or normal mode. pick your fighter 💀

---

💖 Description 💖

so this struct is literally used to program the Data Port based on Data Port stream parameters. that's the whole job. it's giving "small but crucial" main character energy ✨🔥

💜 ngl this one's a short read, so go read the rest of the SoundWire girlies too, iykyk

okay bye bestie, mwah 🍓 — this iconic little page lives in ./include/linux/soundwire and it's dated October 2026, so yeah, it's from the future and still slaying 💅🌈⭐
