STRUCT DRM_NOUVEAU_SYNC(9)

💅 struct drm_nouveau_sync(9) — the Kernel API Manual, bestie edition 🎀

okay so you're in the Kernel API Manual and the star of the show today is literally struct drm_nouveau_sync(9) — a whole sync object, iconic behavior only ✨

---

🌸 NAME 🌸

struct drm_nouveau_sync — it's a sync object, that's the whole vibe 🫶

---

⭐ SYNOPSIS ⭐

here's the struct in all her glory, copy it exactly please, no typos, we don't do that here 💅

struct drm_nouveau_sync {
    __u32 flags;
  #define DRM_NOUVEAU_SYNC_SYNCOBJ 0x0;
  #define DRM_NOUVEAU_SYNC_TIMELINE_SYNCOBJ 0x1;
  #define DRM_NOUVEAU_SYNC_TYPE_MASK 0xf;
    __u32 handle;
    __u64 timeline_value;
 };

like… look at her. the #defines are literally living inside the struct body. that's just how it is, don't question it 🧚

🦋 Members 🦋

• flags — the flags for a sync object 💖 and lowkey the important part: the first 8 bits are what determine the type of the sync object, so those bits are carrying the whole team ngl
• handle — the handle of the sync object, that's it, that's her 🎀
• timeline_value — the timeline point of the sync object, but only in case the syncobj is of type DRM_NOUVEAU_SYNC_TIMELINE_SYNCOBJ (iykyk) ⏱️✨

🌈 Description 🌈

fr fr, this structure serves as a synchronization mechanism for (potentially) asynchronous operations such as EXEC or VM_BIND 🔥

not me being the thing that keeps your async ops from vibing out of order 😭 that's main character energy right there 👑

okay that's the whole page, no cap 💜 this lil drop came from ./include/uapi/drm, dated October 2026, and it's filed under struct drm_nouveau_sync(9) — slay, go forth and sync responsibly 🍓✨
