sdw_master_rt_config(9)

🎀 sdw_master_rt_config 🎀

okay so this is a page from the Kernel API Manual (yes, that Kernel API Manual 💅) and it's about one very specific little function, so let's get into it bestie ✨

---

✨ NAME ✨

sdw_master_rt_config — Configure Master runtime handle 🫶

---

🌸 SYNOPSIS 🌸

int sdw_master_rt_config (struct sdw_master_runtime *m_rt , struct
       sdw_stream_config *stream_config );

like, it returns an int, and it takes exactly those two things. no cap. 🔥

---

💖 ARGUMENTS 💖

• m_rt — the Master runtime handle 🌈 (this is the struct sdw_master_runtime * one, iykyk)
• stream_config — the stream configuration 🎀 (that's your struct sdw_stream_config *)

---

🦋 DESCRIPTION 🦋

so here's the whole vibe: this function is to be called with bus_lock held. that's it, that's the tea ☕

⚠️ bestie please read this one twice — you must be holding bus_lock when you call this. the manpage says it, so it's fr fr serious 😭🔒
