💖 vmw_gb_surfa...ce_ext_ioctl(9) 💖

okay bestie, welcome to the Kernel API Manual page for vmw_gb_surfa...ce_ext_ioctl(9). This is the cute-but-accurate rundown, no cap 💅

🌸 NAME 🌸

vmw_gb_surface_reference_ext_ioctl — the ioctl function implementing the user surface reference functionality. That's the whole NAME vibe: it's the ioctl that does the user surface reference thing ✨

🦋 SYNOPSIS 🦋

here's the exact signature, bestie, copied with love and zero edits:

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

It returns int, and it takes those three pointers. Periodt.

🎀 ARGUMENTS 🎀

• dev — pointer to a struct drm_device. literally that device pointer energy 🫶
• data — pointer to data copied from / to user-space. the from / to slash stays, iykyk 💫
• file_priv — pointer to a drm file private structure. private-structure bestie 🌸
