amdgpu_pasi...fpriv_locked(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual page for amdgpu_pasi...fpriv_locked(9) — and the function at the center of it all is amdgpu_pasid_get_fpriv_locked, which is literally here to get the DRM owner of a PASID. that's the whole assignment. iconic. ✨

---

🦋 SYNOPSIS 🦋

struct amdgpu_fpriv * amdgpu_pasid_get_fpriv_locked (u32 pasid );

---

🌸 ARGUMENTS 🌸

• pasid — the PASID to resolve. that's it, that's the argument, and it's doing its little main-character job 💅

---

🎀 DESCRIPTION 🎀

okay so listen closely, because this part is important: the caller must hold the PASID XArray lock. no cap, that's a requirement, not a suggestion. 🔒

🚨 bestie, the returned pointer is only valid while the PASID lock remains held and must not be retained after calling amdgpu_pasid_unlock. like, do not keep it around after unlock. that's the rule. periodt. 💀

---

⭐ RETURN ⭐

it returns a pointer to the owning DRM file private, or NULL if the PASID has no current owner. simple, clean, very demure. 🫶
