debug_register_static(9)

💅 debug_register_static(9)

okay so this is a page straight out of the Kernel API Manual and honestly? she's a short one but she matters 💖 bestie, if you're messing with static debug areas on s390, this is your girl.

---

✨ NAME ✨

debug_register_static — literally just registers a static debug area. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int debug_register_static (debug_info_t *id , int pages_per_area , int
nr_areas );

three args, one int back. no cap, that's it. 🦋

---

🎀 ARGUMENTS 🎀

• id — the handle for your static debug area. your little main-character pointer, a debug_info_t *. 👑
• pages_per_area — how many pages per area. yes, exactly what it sounds like. 🔥
• nr_areas — the number of debug areas. the more the merrier, i guess. ✨

---

💜 DESCRIPTION 💜

so what she does is register a debug_info_t that you defined using DEFINE_STATIC_DEBUG_INFO. that's the tea. 🍓

---

🦋 NOTE 🦋

lowkey important: you don't even have to call this yourself — it's called automatically via an initcall that DEFINE_STATIC_DEBUG_INFO generates for you. she's got main character energy and shows up on her own. 💅

---

⭐ RETURN ⭐

• 0 on success — slay, it worked 🎉
• a negative error code on failure — not slay, something went wrong 😭
