dmub_srv_get_preos_info(9)

💅 dmub_srv_get_preos_info — a whole kernel page, but make it cute

okay so bestie, welcome to the dmub_srv_get_preos_info(9) page from the Kernel API Manual ✨ — yes it's a kernel function, yes it's giving "graphics driver internals", and yes we're gonna get through it together 🫶

---

🌸 NAME 🌸

dmub_srv_get_preos_info — retrieves preos fw info</p> 💖

---

🎀 SYNOPSIS 🎀

bool dmub_srv_get_preos_info (struct dmub_srv *dmub );

that's it. one function, one return type, one argument. clean, minimal, iconic 🌈

---

🦋 ARGUMENTS 🦋

• dmub — the dmub service. that's the whole vibe. it's the dmub service and it's the main character here 👑

---

⭐ RETURN ⭐

• true — preos fw info retrieved successfully 🎉 ate and left no crumbs
• false — preos fw info not retrieved successfully 😭 not slaying, not today

like bestie it's a bool, there's literally two options, and one of them is a sad one 💀

ngl bestie, this is a kernel API page, so keep your struct dmub_srv * close and your bool closer 🧚

and that's the whole thing, no crumbs left 🍓 the source lives over at ./drivers/gpu/drm/amd/display/... and it's dated October 2026, footer signed off in true dmub_srv_get_preos_info(9) fashion — mwah, go read some structs 💜✨
