that's it. that's the whole vibe. returns nothing (void), takes one pointer, gates closed 💅

okay so here's the tea ☕ — this function selects the proper CPU, and then runs qman_delete_cgr there. on that CPU. the correct one. because doing it on the wrong CPU would be a whole mess and we don't do mess 💀

no cap, that's the entire description. she's short and sweet and knows exactly what she's about 🦋
