amdgpu_devic...s_dc_support(9)

🌸 amdgpu_devic...s_dc_support 💅

okay bestie so this is a page from the Kernel API Manual (yes, the kernel, we're being fancy today ✨) and it's about one tiny little function that answers one tiny little question. it's giving "small but important." let's go 🫶

---

✨ NAME ✨

amdgpu_device_has_dc_support — literally just checks if dc is supported 💖 that's the whole job. that's the assignment. she ate and left no crumbs 🍓

---

🦋 SYNOPSIS 🦋

bool amdgpu_device_has_dc_support (struct amdgpu_device *adev );

it takes one thing and gives you back a bool, no cap. true or false, that's it, that's the vibe check ⭐

---

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer 🌈 that's your device, bestie, the lil handle to the thing we're asking about. this is the only thing you have to hand her.

---

💜 DESCRIPTION 💜

so here's the tea ☕: this function returns true for supported, and false for not supported. that's it. that's the whole description. no hidden lore, no extra behaviour, no secret third option — genuinely just a yes/no girlie 🙈

like, it's not doing anything sneaky. true = supported, false = not supported. periodt 💅

okay this is the part where we do the group chat roll call 📣 because pretty much the entire amdgpu_device friend group shows up here.

first up, the actual kernel file this lives in — it's ./drivers/gpu/drm/amd/amdgpu/amdgpu_device.c 💖 (aka where the source is, iykyk).

like... that is a lot of friends 😭 and yes, amdgpu_device_asic_has_dc_support(9) is in there too — the cousin with the similar name. don't confuse them bestie, they are different girlies 💀
