✨ vmw_resource_do_validate(9) ✨

💖 NAME 💖

vmw_resource_do_validate — Make a resource up-to-date and visible to the device. no cap, that’s the whole vibe. ✨

---

🎀 SYNOPSIS 🎀

int vmw_resource_do_validate (struct vmw_resource *res , struct ttm_validate_buffer *val_buf , bool dirtying );

---

🦋 ARGUMENTS 🦋

• res — the resource you’re making visible to the device. main character resource energy. 👑
• val_buf — information about a buffer possibly containing backup data if a bind operation is needed. like the group-chat context for the bind, bestie. 💬
• dirtying — transfer dirty regions. literally that. 🫶

---

🌸 DESCRIPTION 🌸

okay so if there’s a hardware resource shortage, this function returns -EBUSY and should be retried once resources have been freed up. that’s the whole note — don’t panic, just free stuff up and try again. 💀✨
