STRUCT NE_PHYS_CONTIG_MEM_REGIONS(9)

💖 struct ne_phys_contig_mem_regions(9) 💖

okay so this is a page straight out of the Kernel API Manual, and it's all about one lil struct that keeps track of contiguous physical memory regions 🎀 that's it, that's the vibe.

---

✨ NAME ✨

struct ne_phys_contig_mem_regions — Contiguous physical memory regions. 💅

---

🦋 SYNOPSIS 🦋

bestie, here's the whole struct, look at her 👑

struct ne_phys_contig_mem_regions {
    unsigned long num;
    struct range  *regions;
 };

---

🌸 Members 🌸

• num — the number of regions that currently has. yep, that's the count, she's literally counting 🧮
• regions — the array of physical memory regions. the actual lineup, the whole squad of them 🫶
