💅 vmw_move_notify — a Kernel API Manual moment 🎀

okay so bestie, welcome to vmw_move_notify(9), straight out of the Kernel API Manual ✨ this one is short, sweet, and honestly kind of a vibe.

🌸 NAME 🌸

vmw_move_notify — literally the TTM move_notify_callback. that's it, that's the whole name. iykyk 💅

---

✨ SYNOPSIS ✨

void vmw_move_notify (struct ttm_buffer_object *bo , struct ttm_resource
*old_mem , struct ttm_resource *new_mem );

three pointers, no return value, no drama. she's a void. iconic. 🫶

🦋 ARGUMENTS 🦋

• bo — the TTM buffer object that is about to move. yes bestie she's packing her bags 😭
• old_mem — the old memory, aka the place we're moving from. the ex. the previous address. 💀
• new_mem — the struct ttm_resource that tells you which memory region the move is actually taking place into. the glow-up destination ✨

---

💖 DESCRIPTION 💖

so what does she do? she calls move_notify for every subsystem that needs it. that's the whole job. and currently? that's only resources. lowkey a short guest list but we respect it 👑

no cap, the entire function is a notification girlie. she moves, she notifies, she leaves. main character energy fr fr 🌈
