STRUCT DRM_PANTHOR_SYNC_OP(9)

💖 struct drm_panthor_sync_op(9) — the Kernel API Manual glow-up 💖

okay so bestie, we're in the Kernel API Manual today and this one's a whole little struct — it's struct drm_panthor_sync_op, and it's literally just a synchronization operation. that's the vibe. it's giving "small but mighty". 🎀

---

✨ NAME ✨

struct drm_panthor_sync_op — a Synchronization operation. periodt. 💅

---

🌸 SYNOPSIS 🌸

here's the shape of it, copy it exactly bestie, don't freestyle:

struct drm_panthor_sync_op {
    __u32 flags;
    __u32 handle;
    __u64 timeline_value;
 };

---

🦋 Members 🦋

okay so this struct has exactly three members and we're gonna meet all three, no skipping, i promise 🫶

• flags — the Synchronization operation flags. it's a combination of the DRM_PANTHOR_SYNC_OP values. mix and match, icon behavior. ⭐
• handle — the Sync handle. that's it. that's the whole member. short king. 👑
• timeline_value — this one's conditional and you have to respect it: it's MBZ if (flags & DRM_PANTHOR_SYNC_OP_HANDLE_TYPE_MASK) != DRM_PANTHOR_SYNC_OP_HANDLE_TYPE_TIMELINE_SYNCOBJ. so like… read the flags first, then fill this in. don't come for me. 🙈
