STRUCT AMDXDNA_DRM_SYNC_BO(9)

💅 struct amdxdna_drm_sync_bo(9) — the Kernel API Manual ✨

okay so bestie, welcome to the struct amdxdna_drm_sync_bo(9) page from the Kernel API Manual — this is literally the little struct that tells everyone "hey, sync THIS buffer object, in THIS direction, right HERE, and it's THIS big" 🎀

---

🌸 NAME 🌸

struct amdxdna_drm_sync_bo — the sync buffer object. that's it, that's the vibe 💖

---

✨ SYNOPSIS ✨

here's the whole thing, character for character, no cap:

struct amdxdna_drm_sync_bo {
    __u32 handle;
  #define SYNC_DIRECT_TO_DEVICE   0U;
  #define SYNC_DIRECT_FROM_DEVICE 1U;
    __u32 direction;
    __u64 offset;
    __u64 size;
 };

like... look at her. so structured. so organized. main character energy fr 👑

🦋 Members 🦋

• handle — the buffer object handle. this is the little name-tag that says which buffer object we're talking about 🫶
• direction — the direction of the sync, and lowkey the whole point: it can go from the device or to the device. the two #defines up there in the synopsis are SYNC_DIRECT_TO_DEVICE (0U) and SYNC_DIRECT_FROM_DEVICE (1U), so you literally cannot get confused about which way the data is flowing 💅
• offset — the offset in the buffer where the syncing happens. not the whole thing, just the spot 📍
• size — the size, in bytes. how many of them. the amount. iconic 🌈

ngl this page is short but she ate. read the SEE ALSO list if you wanna go deeper, bestie — that's where the lore is 🧚

and that's a wrap!! this page came out of ./include/uapi/drm and it's dated October 2026 — ty for coming to my TED talk, mwah 💋🍓 periodt.
