       drm_xe_engine_class_instance eci );

no cap, that's the whole signature. she takes two things and hands you back a pointer (or doesn't — we'll get there, don't rush her 😭).

💖 DESCRIPTION 💖

👑 SEE ALSO 👑

like, the whole friend group fr fr 🫶 go say hi to all of them.

ngl bestie, if you get a NULL back, that's not a bug in your code — that's just her telling you that class:instance combo does not exist 💀 check your eci before you spiral 🙈
