💅 dmub_srv_create(9)

okay so this is a page from the Kernel API Manual, and honestly? we're starting at the very beginning, bestie — the birth of the whole DMUB service. 🎀

✨ NAME ✨

dmub_srv_create — creates the DMUB service.

like, it makes the thing. the origin story. the main character entrance. 🦋

---

🌸 SYNOPSIS 🌸

enum dmub_status dmub_srv_create (struct dmub_srv *dmub , const struct
       dmub_srv_create_params *params );

---

🫶 ARGUMENTS 🫶

• dmub — the dmub service 💖 (yes, the struct you're about to breathe life into)
• params — creation parameters for the service ✨ (all the setup deets it needs to be born correctly)

---

⭐ RETURN ⭐

• DMUB_STATUS_OK — success!! slay, it worked, we ate 🔥
• DMUB_STATUS_INVALID — unspecified error 😭 like, something went wrong but nobody's saying what. vague on purpose. not iconic of it tbh

💀 reminder bestie: you literally cannot do anything else in this list until dmub_srv_create has run. it's the vibe check the entire service has to pass first. no create, no service. periodt.
