ENUM SDW_STREAM_STATE(9)

🌈 enum sdw_stream_state — the kernel API manual, but make it make sense 💅

okay bestie, so this is a page straight out of the Kernel API Manual, and it's literally just the glow-up journey of a SoundWire stream ✨ like, the whole entire lifecycle from "just born" to "gone" 🎀 and every single state along the way needs its moment.

The name of the thing? enum sdw_stream_state — the stream states, periodt. 👑

---

✨ NAME ✨

enum sdw_stream_state — stream states 💖 like... literally the states a stream can be in, no cap.

---

🦋 SYNOPSIS 🦋

okay so here's the whole squad, in order, one per line, exactly like this:

enum sdw_stream_state {
    SDW_STREAM_ALLOCATED ,
    SDW_STREAM_CONFIGURED ,
    SDW_STREAM_PREPARED ,
    SDW_STREAM_ENABLED ,
    SDW_STREAM_DISABLED ,
    SDW_STREAM_DEPREPARED ,
    SDW_STREAM_RELEASED

};

that's it, that's the enum 🫶 notice how there's a lil blank line before the closing brace — yeah, that's canon, don't come for me.

🧚 Constants 🧚

every single one of these is a whole main character, so let's do a vibe check on each:

• SDW_STREAM_ALLOCATED — new stream allocated 🌱 the fresh baby, just spawned into existence.
• SDW_STREAM_CONFIGURED — stream configured ⚙️ it's got its settings on now, look at it go.
• SDW_STREAM_PREPARED — stream prepared 🎀 prepped and ready, like when you've done your skincare and you're set for the day.
• SDW_STREAM_ENABLED — stream enabled 🔥 it's ON. living its truth. slaying.
• SDW_STREAM_DISABLED — stream disabled 💀 turned off, napping, not currently serving.
• SDW_STREAM_DEPREPARED — stream de-prepared 🙈 the un-prepping happened, it's undoing the prep era.
• SDW_STREAM_RELEASED — stream released 🦋 free, let go, off to the great beyond.

okay that's the whole page, no notes 💅 this came from ./include/linux/soundwire, dated October 2026, and it's filed under enum sdw_stream_state(9) — mwah, bye bestie, go forth and stream responsibly 🌸🫶
