💅 register_me...compute_node(9) 💅

okay bestie, this page is from the Kernel API Manual, and it's giving “kernel plumbing but make it cute” ✨

🎀 NAME 🎀

register_memory_node_under_compute_node — links a memory node to its compute node for a given access class 🫶

🌸 SYNOPSIS 🌸

int register_memory_node_under_compute_node (unsigned int mem_nid ,
       unsigned int cpu_nid , enum access_coordinate_class access );

🧚 ARGUMENTS 🧚

• mem_nid — memory node number 💖
• cpu_nid — Cpu node number 🌈
• access — access class to register ⭐

🔥 DESCRIPTION 🔥

This one is for platforms that may have separate memory and compute nodes — yes, they can be different, and that's literally the whole point 💀

The function exports node relationships: the link that says which memory initiator nodes can access memory targets at a given ranked access class. So it's basically matchmaking for nodes, but with access class rankings 👑
