💅 dc_dmub_srv_...s_dmcub_info(9)

okay bestie, welcome to the Kernel API Manual ✨ — yes this is a kernel API manual page, yes it's from the Kernel API Manual section, and yes we're gonna read it together like it's the most iconic thing ever. (it lowkey is 🫶)

---

🌸 NAME 🌸

dc_dmub_srv_log_preos_dmcub_info — it logs preos dmcub fw info. that's the whole vibe. it logs it. preos. dmcub. fw. info. 🎀

---

✨ SYNOPSIS ✨

void dc_dmub_srv_log_preos_dmcub_info (struct dc_dmub_srv *dc_dmub_srv
);

so it's a void function, meaning it gives you nothing back, it just does the thing and leaves 💅 and it takes exactly one argument, a struct dc_dmub_srv * named dc_dmub_srv. that's it. that's the whole signature. ate.

---

🦋 ARGUMENTS 🦋

• dc_dmub_srv — okay so the manpage literally just says -- undescribed -- 😭 no cap, the docs did NOT show up for this one. it's the struct dc_dmub_srv * from above, that's all we're officially told. the manpage is being mysterious and honestly? main character energy.

---

👑 DESCRIPTION 👑

• dc — pointer to DC object 🌈

that's it. that's the description. one line. one little pointer. it's giving minimalism, it's giving "the intern wrote the docs", and we respect it fr fr 🎀

no cap bestie — that single line about dc is literally all the description this page gives you. don't go inventing extra behaviour for it, because the manual doesn't say 💀
