💖 memblock_mark_hotplug 💖

okay bestie, welcome to the memblock_mark_hotplug(9) page — that's a section 9 kernel API manual entry, so get comfy because we're in kernel-nerd territory and honestly? it's giving main character energy 🌈

---

✨ NAME ✨

memblock_mark_hotplug — marks hotpluggable memory with the flag MEMBLOCK_HOTPLUG. that's it, that's the whole job, and she does it slayfully 💅

---

🦋 SYNOPSIS 🦋

int __init_memblock memblock_mark_hotplug (phys_addr_t base ,
phys_addr_t size );

look at her. int return, __init_memblock, takes a base and a size. iconic signature, no notes ✨

---

🎀 ARGUMENTS 🎀

• base — the base phys addr of the region 💖 so like, where the region starts, physically
• size — the size of the region 🌸 how much of it there is, starting from base

---

⭐ RETURN ⭐

• 0 on success 🫶 (we love a zero)
• -errno on failure 😭 (classic kernel move — negative errno, no cap)

---
