STRUCT ESTACK_PAGES(9)

okay so bestie, welcome to the struct estack_pages(9) page in the Kernel API Manual — we're talking page descriptors for exception stacks, and it's honestly iconic 💖

🎀 NAME 🎀

struct estack_pages — page descriptor for exception stacks. that's the whole vibe: it's the descriptor for exception stack pages, slay ✨

✨ SYNOPSIS ✨

struct estack_pages {
    u32 offs;
    u16 size;
    u16 type;
 };

💅 Members 💅

okay so the struct has exactly three members, and yes they all matter:

• offs (u32) — offset from the start of the exception stack area. literally the starting point 📍
• size (u16) — size of the exception stack. it's giving "how big is this stack" energy 📏
• type (u16) — type to store in the stack_info struct. that's the type that goes into stack_info, no cap 🏷️

🌈 SEE ALSO 🌈

• Kernel file ./arch/x86/kernel/dumpstack_64.c — this is the spot the page points you to, bestie 🫶
