vmw_cotable_unbind(9)

💅 vmw_cotable_unbind(9) — your girl's guide to the cotable unbind callback

okay so this is from the Kernel API Manual bestie, and it's genuinely such a tiny little function but she does exactly what she says on the tin. no notes. 💖

---

✨ NAME ✨

vmw_cotable_unbind — the cotable resource unbind callback. that's it, that's her whole job description 🎀

---

🌸 SYNOPSIS 🌸

int vmw_cotable_unbind (struct vmw_resource *res , bool readback ,
       struct ttm_validate_buffer *val_buf );

like look at that signature, so clean, so iconic ✨

---

🦋 ARGUMENTS 🦋

• res — pointer to the cotable resource. the main character of this whole situation, tbh 👑
• readback — a bool that says whether to read back the cotable data into the backup buffer. yes or no bestie, that's the whole vibe check 🙈
• val_buf — pointer to a struct ttm_validate_buffer that the caller prepared, literally just for convenience / fencing. the caller already did the homework and this is the handout 🫶

---

💜 DESCRIPTION 💜

so what does she actually do? she unbinds the cotable from the device, and she fences the backup buffer. that's the whole plot. no cap. 🔥

lowkey a short one but that's a slay, not everything needs to be a whole saga 💀
