STRUCT SMEM_GLOBAL_ENTRY(9)

💅 struct smem_global_entry(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ — today's main character is struct smem_global_entry, and honestly? she's the entry that lets you reference smem items on the heap 🎀

🌸 NAME 🌸

struct smem_global_entry — entry to reference smem items on the heap 🫶

✨ SYNOPSIS ✨

struct smem_global_entry {
    __le32 allocated;
    __le32 offset;
    __le32 size;
    __le32 aux_base;
 };

literally the whole struct, no cap 💅 four little __le32 fields and she's done.

🦋 Members 🦋

• allocated — a boolean vibe check 🔥 it says whether this entry is actually used or just sitting there being decorative.
• offset — the offset to the allocated space, i.e. where the good stuff starts 📍
• size — how big the allocated space is, and yes it's 8 byte aligned — she's organized like that 💖
• aux_base — the base address for the memory region this unit uses, or 0 for the default region 🌈 careful though: bits 0,1 are reserved 🙈 so don't be out here touching them.
