💖 sdw_stream_add_master(9) 💖

okay so first things first, bestie: we're in the Kernel API Manual today, and this little function is called sdw_stream_add_master — and yes, the (9) is part of the name, it's giving kernel-section energy, we love that for us. 🎀

✨ NAME ✨

sdw_stream_add_master — allocate and add a master runtime</> to a stream. that's it, that's the whole vibe. 💅

---

🌸 SYNOPSIS 🌸

int sdw_stream_add_master (struct sdw_bus *bus , struct
sdw_stream_config *stream_config , const struct sdw_port_config
*port_config , unsigned int num_ports , struct sdw_stream_runtime
*stream );

like, look at all those parameters. she's got range. 🔥

🦋 ARGUMENTS 🦋

• bus — your SDW Bus instance. the main character, the venue, the whole bus. 🚌
• stream_config — the stream configuration for the audio stream. the ~plan~, if you will.
• port_config — the port configuration for the audio stream. which ports are doing what, bestie.
• num_ports — number of ports. literally just the count, no cap. 🔢
• stream — the SoundWire stream itself. the actual stream. the moment. ✨
