vmw_user_bo_synccpu_ioctl(9)

✨ NAME ✨

vmw_user_bo_synccpu_ioctl — okay bestie, this is the ioctl function that implements the synccpu functionality. iconic behavior honestly 💅

---

🦋 SYNOPSIS 🦋

int vmw_user_bo_synccpu_ioctl (struct drm_device *dev , void *data ,
       struct drm_file *file_priv );

---

🎀 ARGUMENTS 🎀

• dev — identifies the drm device, like the main character ofc 👑
• data — pointer to the ioctl argument, the lil payload bestie 🍓
• file_priv — identifies the caller, so we know who's asking 🙈

---

🌸 RETURN 🌸

Zero on success, negative error code on error. that's it that's the vibe check ✨

---

💖 DESCRIPTION 💖

This function checks the ioctl arguments for validity and calls the relevant synccpu functions. so it's like the bouncer at the club — makes sure your args are valid before letting them through to the actual work. no cap, that's literally the whole job 🫶
