memory_group...ister_static(9)

💖 NAME 💖

okay so bestie, this is the Kernel API Manual page for memory_group_register_static — the function that registers a static memory group. That’s literally the whole vibe: register a static memory group. Slay. ✨

🎀 SYNOPSIS 🎀

int memory_group_register_static (int nid , unsigned long max_pages );

💜 ARGUMENTS 💜

• nid — the node id, bestie. That’s the whole argument. No cap. 🫶
• max_pages — the maximum number of pages we’ll have in this static memory group. Iconic limit behavior. 💅

🌸 DESCRIPTION 🌸

Register a new static memory group and return the memory group id. All memory in the group belongs to a single unit, such as a DIMM. 🧚

All memory belonging to a static memory group is added in one go to be removed in one go — it’s static, periodt. 💀

It returns an error if it’s out of memory, if the node id is invalid, if no new memory groups can be registered, or if max_pages is invalid (0). Otherwise, it returns the new memory group id. Literally that simple. 🌈
