STRUCT KOBJ_ECLASS(9)

💅 struct kobj_eclass(9) — from the Kernel API Manual, bestie

okay so picture this: it's a manual page, it's section 9, and it's literally called struct kobj_eclass. welcome to the group chat 🫶

---

✨ NAME ✨

struct kobj_eclass — an eclass's kobject struct, and its whole entire job is connecting the kobject and the eclass together. like a little matchmaker 🎀

---

🦋 SYNOPSIS 🦋

struct kobj_eclass {
    struct kobject base;
    struct xe_hw_engine_class_intf *eclass;
    struct xe_device *xe;
 };

she's compact, she's iconic, she's three fields and a dream ✨

---

🌸 Members 🌸

• base — the actual kobject. that's her. the real one. no cap 💅
• eclass — a pointer to the hw engine class interface 👑
• xe — a pointer to the xe device 🦋

---

💖 Description 💖

so when you're dealing with multiple eclass (plural! a whole squad!), this struct is the one that helps you figure out which eclass needs to be addressed on a given sysfs call. it's giving main character energy in a crowd of eclasses, fr fr 😭

and that's the whole page, bestie, go off 💜
