STRUCT NODE_ACCESS_NODES(9)

💅 struct node_access_nodes(9) ✨

okay so bestie, welcome to the Kernel API Manual 🫶 — this one's a lil struct that's basically the group chat link between a memory access class and all the other nodes it's connected to. Let's get into it. 🦋

---

🌸 NAME

struct node_access_nodes — bestie it's an Access class device whose whole job is holding the user-visible relationships to other nodes. that's it, that's the vibe. 💖

---

✨ SYNOPSIS

struct node_access_nodes {
    struct device           dev;
    struct list_head        list_node;
    unsigned int            access;
  #ifdef CONFIG_HMEM_REPORTING;
    struct access_coordinate        coord;
  #endif;
 };

like, look at her. iconic. 👑

🎀 Members

• dev — the Device for this memory access class, the main character energy of the whole struct fr fr 💫
• list_node — a List element hanging out in the node's access list, just vibing in the chain 🔗
• access — The access class rank, aka the popularity ranking, the who's-who of access classes ⭐
• coord — the Heterogeneous memory performance coordinates, and ngl she's lowkey gatekept behind CONFIG_HMEM_REPORTING so don't come for her if she's not there 🙈

heads up bestie: coord only exists when CONFIG_HMEM_REPORTING is defined, so if you built without it, that member said "not me being absent" 💀

that's the whole page babes, no notes. 🌈

mwah 💋 — this came from ./drivers/base, dated October 2026, and yes she's serving struct node_access_nodes(9) realness till the very last line. slay 🎀✨
