amdgpu_ttm_tt_pde_flags(9)

💅 amdgpu_ttm_tt_pde_flags(9) — from the Kernel API Manual, bestie

Okay so this is a page straight out of the Kernel API Manual (amdgpu_ttm_tt_pde_flags(9)), and it is exactly what it sounds like: a tiny little helper that works out your PDE flags. Let's get into it ✨

---

🌸 NAME 🌸

amdgpu_ttm_tt_pde_flags — compute PDE flags for a ttm_tt object 🎀

---

🦋 SYNOPSIS 🦋

uint64_t amdgpu_ttm_tt_pde_flags (struct ttm_tt *ttm , struct
       ttm_resource *mem );

Look at her. Returns a uint64_t, takes two args, minding her own business. Iconic behavior honestly 👑

---

💖 ARGUMENTS 💖

• ttm — the ttm_tt object you're computing the flags for 🫶 she's the main character here
• mem — the memory registry backing this ttm_tt object 🌈 aka the stuff behind the scenes making it all work

---

🧚 DESCRIPTION 🧚

So the whole vibe of this function is: figure out the flags to use for a VM PDE (Page Directory Entry). That's it. That's the gig. No cap, that's literally what it does 💅
