amdgpu_dmabu...i_accessible(9)

💅 amdgpu_dmabu...i_accessible(9) — like, the Kernel API Manual page you didn't know you needed 🦋

okay so bestie, welcome to the Kernel API Manual entry for amdgpu_dmabu...i_accessible(9) — yes the header is literally truncated like that, no cap, that's just how it's printed and we're not gonna pretend otherwise 🙈. Buckle up, this one's a tiny lil boolean check and it's lowkey iconic.

✨ NAME ✨

amdgpu_dmabuf_is_xgmi_accessible — the vibe check that tells you if xgmi is available for P2P transfer 🔥

🌸 SYNOPSIS 🌸

bool amdgpu_dmabuf_is_xgmi_accessible (struct amdgpu_device *adev ,
struct amdgpu_bo *bo );

🎀 ARGUMENTS 🎀

• adev — the amdgpu_device pointer of the importer 👑 (i.e. the one doing the importing, main character energy)
• bo — the amdgpu buffer object 🧚

⭐ RETURN ⭐

True if the dmabuf is accessible over xgmi, false otherwise. That's it. That's the whole answer. Short king behavior fr fr 💀

Heads up bestie: it's a bool, so you're getting a yes-or-no, not a maybe. Don't @ me.
