STRUCT DRM_MSM_VM_BIND_OP(9)

🦋 struct drm_msm_vm_bind_op(9) 🦋

okay bestie, welcome to the Kernel API Manual — yes we're reading kernel headers for fun now, this is who we are 💅

✨ NAME ✨

struct drm_msm_vm_bind_op — literally the bind/unbind op to run 🎀

🌸 SYNOPSIS 🌸

struct drm_msm_vm_bind_op {
    __u32 op;
    __u32 handle;
    __u64 obj_offset;
    __u64 iova;
    __u64 range;
    __u32 flags;
    __u32 pad;
 };

look at her. seven fields. main character energy, no notes 👑

💖 Members 💖

• op — one of the MSM_VM_BIND_OP_x values. this is the "what are we even doing here" field 🫶
• handle — the GEM object handle. MBZ for UNMAP or MAP_NULL — so if you're unmapping, don't be cute, leave it at zero.
• obj_offset — offset into the GEM object. also MBZ for UNMAP or MAP_NULL. same vibe check as above ✨
• iova — the address to operate on. this is the "where" of it all 📍
• range — the number of bites to to map/unmap 😭 (the manpage really said "bites" and honestly? we're keeping her. it's how many of them to map/unmap).
• flags — a bitmask of MSM_VM_BIND_OP_FLAG_x. stack 'em, mask 'em, slay.
• pad — MBZ. must be zero. do not touch. do not decorate. zero. 🔥

ngl the recurring theme here is MBZ, so if you were looking for a place to be creative with your values… this is not it bestie 🙈
