STRUCT DRM_PANTHOR_VM_BIND_OP(9)

💖 struct drm_panthor_vm_bind_op(9) 💖

okay so bestie, welcome to the Kernel API Manual 🎀 — this one's from ./include/uapi/drm, dated October 2026, and it's all about the struct drm_panthor_vm_bind_op. it's giving VM bind operation, and honestly? iconic. let's get into it ✨

---

✨ NAME ✨

struct drm_panthor_vm_bind_op — VM bind operation 🦋

like, that's the whole vibe. one struct, one job, no cap.

---

🌸 SYNOPSIS 🌸

struct drm_panthor_vm_bind_op {
    __u32 flags;
    __u32 bo_handle;
    __u64 bo_offset;
    __u64 va;
    __u64 size;
    struct drm_panthor_obj_array syncs;
 };

look at her. six fields. flawless. main character energy fr fr 👑

💅 MEMBERS 💅

• flags — bestie this is a combination of drm_panthor_vm_bind_op_flags flags. that's it, that's the field 🌈
• bo_handle — the handle of the buffer object you wanna map. MBZ for unmap or sync-only operations 🫶 (MBZ = must be zero, and yes the kernel is literally checking 👀)
• bo_offset — buffer object offset. again, MBZ for unmap or sync-only operations 💖
• va — the virtual address to map/unmap. MBZ for sync-only operations ⭐
• size — how big the map/unmap is. MBZ for sync-only operations 🍓
• syncs — an array of struct drm_panthor_sync_op synchronization operations 🧚

⚠️ okay this part matters, so listen up: this array must be empty if DRM_PANTHOR_VM_BIND_ASYNC is not set on the drm_panthor_vm_bind object containing this VM bind operation. no exceptions, she's strict 😭

💀 and the flip side: this array shall not be empty for sync-only operations. so don't leave it empty there either. the vibes must be exactly right ✨
