STRUCT DRM_ASAHI_GEM_BIND_OBJECT(9)

💅 struct drm_asahi_gem_bind_object(9) — Kernel API Manual ✨

okay bestie, so this is a page straight out of the Kernel API Manual, and it's all about struct drm_asahi_gem_bind_object — the little argument bundle you hand over when you call DRM_IOCTL_ASAHI_GEM_BIND_OBJECT. it's giving "the paperwork you fill out before the kernel does something iconic" 🎀

---

🌸 NAME 🌸

struct drm_asahi_gem_bind_object — the arguments passed to DRM_IOCTL_ASAHI_GEM_BIND_OBJECT. that's it, that's the whole vibe. 🦋

---

✨ SYNOPSIS ✨

here's the whole struct, copied exactly, no cap:

struct drm_asahi_gem_bind_object {
    __u32 op;
    __u32 flags;
    __u32 handle;
    __u32 vm_id;
    __u64 offset;
    __u64 range;
    __u32 object_handle;
    __u32 pad;
 };

look at that layout. the __u32s up top, the __u64s in the middle, chef's kiss 🧚

🫶 Members 🫶

let's go through the members one by one, because every single one matters fr fr:

• op — the bind operation. it's an enum drm_asahi_bind_object_op, so it's telling the kernel what kind of move you're pulling. main character energy. 👑
• flags — a combination of drm_asahi_bind_object_flags flags. mix and match your little behavior modifiers here. 💅
• handle — the GEM object you're binding or unbinding. this one's for BIND. 🔥
• vm_id — the ID of the VM you're operating on. heads up: it's MBZ currently (that means "must be zero," so don't get cute and put a real value in there 🙈).
• offset — the offset into the object. BIND only, bestie, don't @ me otherwise. ⭐
• range — how many bytes to bind or unbind. also BIND only. 📏
• object_handle — the object handle! it's an out for BIND and an in for UNBIND. yes, it flips direction, she contains multitudes. 🌈
• pad — MBZ. must be zero. literally just sitting there being zero. 💀

lowkey important: vm_id and pad are both MBZ — if you shove garbage in them you're not slaying, you're just breaking things 😭
