STRUCT XE_GGTT_PT_OPS(9)

✨ struct xe_ggtt_pt_ops(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 — we're literally about to talk about struct xe_ggtt_pt_ops, which is the GGTT Page table operations struct, and the whole point is that these ops can vary from platform to platform. iykyk 🦋

🎀 NAME 🎀

struct xe_ggtt_pt_ops — GGTT Page table operations Which can vary from platform to platform. no cap, that's literally the whole vibe 💅

---

🌸 SYNOPSIS 🌸

struct xe_ggtt_pt_ops {
    u64 (*pte_encode_flags)(struct xe_bo *bo, u16 pat_index);
    xe_ggtt_set_pte_fn ggtt_set_pte;
    u64 (*ggtt_get_pte)(struct xe_ggtt *ggtt, u64 addr);
 };

like, that's the whole struct, she's short and iconic 👑

⭐ Members ⭐

• pte_encode_flags — Encode PTE flags for a given BO 🫶 this one does exactly what it says on the tin
• ggtt_set_pte — Directly write into GGTT's PTE ✍️ straight in, no middleman
• ggtt_get_pte — Directly read from GGTT's PTE 👀 again, direct, we love a direct queen
