amdgpu_acpi_is_s3_active(9)

💖 amdgpu_acpi_is_s3_active(9) — the Kernel API Manual tea 🫖

okay bestie, so this is a page from the Kernel API Manual, and it's about one (1) tiny little function that answers one (1) tiny little question. lowkey iconic for that alone ✨

---

🌸 NAME 🌸

amdgpu_acpi_is_s3_active — and honestly? the manpage gives us nothing else here. no tagline, no subtitle, blank. it's giving mysterious main character energy 💅 (no cap, the NAME section really is just the function name and that's it)

---

🦋 SYNOPSIS 🦋

bool amdgpu_acpi_is_s3_active (struct amdgpu_device *adev);

that's the whole vibe check: it hands you back a bool, and it wants a struct amdgpu_device *adev to look at 🔥

---

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device_pointer. that's it, that's the whole argument. it's literally just pointing at your amdgpu device and saying "hey, look at this one" 🫶

---

✨ DESCRIPTION ✨

so what does it do? per the page: it returns true if supported, false if not. periodt. that's the entire description. no extra lore, no side quests, no "but wait there's more" 😭

like yes it's short but it ate and left no crumbs — you call it, you get a bool, you move on with your life 💀

ngl this is the kind of function you call once, nod at, and never think about again. and that's valid 🌈
