ENUM SDW_PORT_DATA_MODE(9)

🎀 enum sdw_port_data_mode(9) 🎀

okay bestie, welcome to the Kernel API Manual — this one's all about enum sdw_port_data_mode, which is literally the Data Port mode and honestly it's giving "small enum, big responsibilities" 💅

---

✨ NAME ✨

enum sdw_port_data_mode — Data Port mode 🦋

---

🌸 SYNOPSIS 🌸

enum sdw_port_data_mode {
    SDW_PORT_DATA_MODE_NORMAL ,
    SDW_PORT_DATA_MODE_PRBS ,
    SDW_PORT_DATA_MODE_STATIC_0 ,
    SDW_PORT_DATA_MODE_STATIC_1

};

like, that's the whole thing. four constants. short king energy 👑

---

💖 Constants 💖

• SDW_PORT_DATA_MODE_NORMAL — the normal data mode, where audio data is received and transmitted. the main character mode fr fr 🎧✨
• SDW_PORT_DATA_MODE_PRBS — test mode which uses a PRBS generator to produce a pseudo random data pattern that is transferred. chaos on purpose, we love to see it 🌀🔥
• SDW_PORT_DATA_MODE_STATIC_0 — simple test mode which uses static value of logic 0. the encoding will result in no signal transitions. flatline vibes, but make it intentional 💀
• SDW_PORT_DATA_MODE_STATIC_1 — simple test mode which uses static value of logic 1. the encoding will result in signal transitions at every bitslot owned by this Port. busy busy busy, every single bitslot is booked and busy 🌈⭐

ngl the PRBS and STATIC modes are test modes — the manpage says so, so don't come for me, i'm just the messenger 🙈

that's the whole page bestie, no cap ✨ this lil icon dropped straight out of ./include/linux/soundwire in October 2026, living under the Kernel API Manual banner — mwah, xoxo, go forth and configure your data ports 💅🎀🌟
