xe_ggtt_encode_pte_flags(9)

✨ xe_ggtt_encode_pte_flags(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a lil function called xe_ggtt_encode_pte_flags, and it's lowkey iconic in a very specific way. let's get into it 🫶

---

🌸 NAME 🌸

xe_ggtt_encode_pte_flags — get those PTE encoding flags for a BO, fr fr 💅

---

🦋 SYNOPSIS 🦋

u64 xe_ggtt_encode_pte_flags (struct xe_ggtt *ggtt , struct xe_bo *bo ,
u16 pat_index );

like, it returns a u64, takes a struct xe_ggtt *, a struct xe_bo *, and a u16. cute, clean, to the point ✨

---

🎀 ARGUMENTS 🎀

• ggtt — a xe_ggtt. that's the one. the whole GGTT vibe 💫
• bo — a xe_bo, obvi. the buffer object in question 🧚
• pat_index — the pat_index for the PTE. yes, exactly that one, no cap 👑

---

🌈 DESCRIPTION 🌈

so what does it actually do? it returns the pte_flags for a given BO — without the address. not me emphasizing that but it matters, okay 😭

it's used for DPT, to fill a GGTT mapped BO with a linear lookup table. that's the whole thing, and it ate 🔥
