STRUCT DRM_PANTHOR_BO_SYNC_OP(9)

✨ NAME ✨

struct drm_panthor_bo_sync_op — the BO map sync op, bestie 💅

okay so this is from the Kernel API Manual, and it's literally the little struct that tells the kernel "hey, sync this chunk of my buffer object for me" 🫶

---

🌸 SYNOPSIS 🌸

struct drm_panthor_bo_sync_op {
    __u32 handle;
    __u32 type;
    __u64 offset;
    __u64 size;
 };

that's the whole vibe. four fields, zero drama ✨

🎀 MEMBERS 🎀

• handle — the handle of the buffer object you wanna sync. that's your BO's little ID badge 🪪
• type — what kind of operation this is, iykyk 👑
• offset — where into the BO your sync range starts.

lowkey important: this gets rounded down to the nearest cache line as needed 🧚 nothing you can do about it, it's just the rules

• size — how big the range you're syncing is.

and size + offset gets rounded up to the nearest cache line as needed 🌈 so your range might come out a lil bigger than you asked for, not smaller, no cap
