✨ vmw_query_move_notify ✨

okay so bestie, welcome to the vmw_query_move_notify(9) page 💅 it lives in the Kernel API Manual and it's genuinely one of those tiny-but-iconic little helpers, iykyk.

🌸 NAME 🌸

vmw_query_move_notify — read back cached query states 🎀

---

🦋 SYNOPSIS 🦋

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

no cap, that's the whole signature. three args, void return, very demure ✨

---

💜 ARGUMENTS 💜

• bo — the TTM buffer object that's about to move. like it's packing its bags fr.
• old_mem — the memory region bo is moving from. the ex, basically 😭
• new_mem — the memory region bo is moving to. the new main character 👑

---

💖 DESCRIPTION 💖

so this one gets called before the query MOB is swapped out, and its whole job is to read back the cached query states from the device. that's it. that's the vibe. it's giving "responsible friend who screenshots the group chat before it disappears" 🫶
