vmw_context_bind_dx_query(9)

💅 NAME 💅

vmw_context_bind_dx_query — okay so this is the girl that sets the query MOB for the context 💖. And bestie, listen: if mob is NULL, she doesn't just sit there — she removes the association between the MOB and the context. Not me writing the breakup arc for a buffer object 😭. Also, tiny but important: this function assumes the binding_mutex is held. Like, that's the prerequisite, she's not locking it for you, iykyk 🔒✨

✨ SYNOPSIS ✨

int vmw_context_bind_dx_query (struct vmw_resource *ctx_res , struct
vmw_bo *mob );

---

🎀 ARGUMENTS 🎀

• ctx_res — the context resource, the main character in this whole situation 👑
• mob — a reference to the query MOB 🫶

---

🦋 DESCRIPTION 🦋

So here's the vibe check: she returns -EINVAL if a MOB has already been set and it does not match the one you passed in the parameter 🙈 (like, conflicting commitments? not on her watch). Otherwise — 0. Slay, we love a clean return 💀✨

Heads up bestie: binding_mutex must already be held when you call this. That's not optional, that's the whole assignment 😤
