STRUCT DRM_INFO_NODE(9)

✨ struct drm_info_node(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a tiny little struct page from struct drm_info_node(9)</pink>, and it's honestly short but kind of iconic. Let's get into it 🎀

---

🌸 NAME 🌸

struct drm_info_node — the per-minor debugfs node structure, aka the little guy that knows which card you're looking at 🦋

---

✨ SYNOPSIS ✨

struct drm_info_node {
    struct drm_minor *minor;
    const struct drm_info_list *info_ent;
 };

---

💅 MEMBERS 💅

• minor — the struct drm_minor that this node belongs to. it's giving "which one is mine" energy 👑
• info_ent — the template for this node ✨ like, the blueprint it got built from.

---

🦋 DESCRIPTION 🦋

So this struct represents a debugfs file, and the way it works is it's basically an instantiation of a struct drm_info_list sitting on a struct drm_minor. two things, fused, one node 🫶

FIXME: 🚨 bestie listen — it genuinely does not make a hole lot of sense that we duplicate debugfs entries for both the render and the primary nodes. that's just how this has organically grown 🌱 it should probably be fixed, with a compatibility link, if needed. no cap, it's a known vibe 💀
