execmem_arch_setup(9)

✨ execmem_arch_setup(9) ✨

okay so bestie, welcome to the Kernel API Manual, section 9 👑 this one's a tiny little hook with main character energy — it's literally called execmem_arch_setup, and it's all about executable memory. iykyk 💅

---

🌸 NAME 🌸

execmem_arch_setup — define parameters for allocations of executable memory

---

🎀 SYNOPSIS 🎀

struct execmem_info * execmem_arch_setup (void );

---

🦋 ARGUMENTS 🦋

• void — no arguments. nothing. zero. the void is voiding 🙈

---

💖 DESCRIPTION 💖

So basically ✨ this is a hook for architectures to define their own parameters for allocations of executable memory. think of it like each architecture getting to set up its own little vibe board of rules 🎨

These parameters should be filled into the execmem_info structure — that's the whole assignment, no cap 📋

And for architectures that do not implement this method? a default set of parameters will be used 🫶 so nobody's left out, the kernel's got you.

---

🔥 RETURN 🔥

It returns a structure defining architecture parameters and restrictions for allocations of executable memory 🌈 — like, the full rundown of what's allowed and what's not for your arch's executable memory. iconic tbh 👑
