💅 v3d_submit_cl_ioctl(9) — Kernel API Manual 💅

okay bestie, welcome to the Kernel API Manual page for v3d_submit_cl_ioctl(9) — it's giving “main character ioctl” energy, and we're gonna read it together. 🦋✨

---

✨ NAME ✨

v3d_submit_cl_ioctl — Submits a job (frame) to the V3D. 💖

---

🎀 SYNOPSIS 🎀

       int v3d_submit_cl_ioctl (struct drm_device *dev , void *data , struct
       drm_file *file_priv );

---

💖 ARGUMENTS 💖

• dev — DRM device. the whole device vibe. 🫶
• data — ioctl argument. the payload bestie. 🎀
• file_priv — DRM file for this fd. yes, this exact fd. 💅

---

🦋 DESCRIPTION 🦋

okay so this is literally the main entrypoint for userspace to submit a 3D frame to the GPU. ✨ Userspace provides the binner command list (if applicable), and the kernel sets up the render command list to draw to the framebuffer described in the ioctl, using the command lists that the 3D engine's binner will produce. 💅🔥

like, that's the whole plot: userspace brings the binner command list when it applies, and the kernel handles setting up the render command list for the framebuffer described in the ioctl, using the command lists from the 3D engine's binner. iconic behavior, fr fr. 👑
