dc_process_d...config_async(9)

🌸 dc_process_dmub_set_config_async(9) 🌸

okay so bestie, welcome to the Kernel API Manual — this is a lil kernel function page and honestly it's giving "one job, does it well" energy 💅 let's get into it.

---

✨ NAME ✨

dc_process_dmub_set_config_async — literally just submits a set_config command 🎀

---

🦋 SYNOPSIS 🦋

bool dc_process_dmub_set_config_async (struct dc *dc , uint32_t
link_index , struct set_config_cmd_payload *payload , struct
dmub_notification *notify );

no cap, that's the whole signature 💖

---

💜 ARGUMENTS 💜

• dc [in] — the dc structure, aka the whole vibe source. it's an input, you're handing it over 🫶
• link_index [in] — link_index: the link index. yes bestie, that's the label and the description, they really said "redundant but make it official" 😭 still an input tho.
• payload [in] — the aux payload. input, incoming, the goods 🍓
• notify [out] — the set_config immediate reply. this one's an output, so it's what comes back to you, not what you send ✨

---

🌈 DESCRIPTION 🌈

So what does it actually do? It submits a set_config command to dmub, and it does it via an inbox message 💌 that's it, that's the tea. short and iconic, honestly.

---

⭐ RETURN ⭐

Returns True if it worked out, False if it didn't 💀 simple as that.

Heads up bestie: this page doesn't say what to do about the False case, it literally just tells you it's a failure. so like… vibe check your own error handling 🙈
