💖 v3d_submit_tfu_ioctl(9) 💖

okay bestie, welcome to the Kernel API Manual page for v3d_submit_tfu_ioctl(9) — title, manual name, all folded in near the top like a cute little ribbon. 🎀 This one is about submitting a TFU job, and it's lowkey iconic.

✨ NAME ✨

v3d_submit_tfu_ioctl — submits a TFU (texture formatting) job to the V3D. That's the whole name section, and it ate. 💅

🦋 SYNOPSIS 🦋

The signature, literally:

int v3d_submit_tfu_ioctl (struct drm_device *dev , void *data , struct
drm_file *file_priv );

🫶 ARGUMENTS 🫶

• dev — the DRM device. Main character device energy, no cap.
• data — the ioctl argument, periodt.
• file_priv — the DRM file for this fd. Yes, this exact fd. 🫶

🌸 DESCRIPTION 🌸

okay so here's the tea: userspace provides the register setup for the TFU, and we do not need to validate it — because the TFU is behind the MMU. That's the whole description, and honestly? It's giving trust the process. 🦋 No extra validation arc, no cap.
