STRUCT DRM_PVR_SYNC_OP(9)

🎀 struct drm_pvr_sync_op(9) 🎀

okay so bestie, welcome to the Kernel API Manual — we're doing a deep dive on struct drm_pvr_sync_op, and honestly? It's giving "small struct, big responsibilities." ✨

---

✨ NAME ✨

struct drm_pvr_sync_op — the object that describes, like, a whole sync operation. that's it, that's the vibe 💅

---

🌸 SYNOPSIS 🌸

here's the whole shape of it, copied exactly because we do not freestyle structs:

struct drm_pvr_sync_op {
    __u32 handle;
    __u32 flags;
    __u64 value;
 };

---

🦋 Members 🦋

okay so every field has lore, let's get into it 👑

• handle — the handle of the sync object. the little name-tag that says which sync object we're talking about 🪪
• flags — a combination of the DRM_PVR_SYNC_OP_FLAG_ flags. yes, combination — you can stack them, it's giving friendship bracelet 🌈
• value — the timeline value for this drm_syncobj. literally the number that says where you are on the timeline ⏱️ now here's the important bit: it's MBZ for a binary syncobj — MBZ means "must be zero," so don't go putting random numbers in there, bestie 🚫💀

fr fr, that's the entire page. tiny struct, immaculate energy 🫶
