v3d_submit_cpu_ioctl(9) 💅

okay so welcome to the Kernel API Manual, bestie — this is the page for v3d_submit_cpu_ioctl(9) and it's giving “kernel function with main character energy” fr fr. Let's get into it. 🫶

✨ NAME ✨

v3d_submit_cpu_ioctl — literally submits a CPU job to the V3D. That's the whole assignment, no cap. 💖

🌸 SYNOPSIS 🌸

int v3d_submit_cpu_ioctl (struct drm_device *dev , void *data , struct
       drm_file *file_priv );

🎀 ARGUMENTS 🎀

• dev — the DRM device. iconic hardware liaison energy.
• data — the ioctl argument. the payload, the moment, the data.
• file_priv — the DRM file for this fd. basically the fd's paperwork. 🗂️

🦋 DESCRIPTION 🦋

so here's the tea: userspace specifies the CPU job type and the data required to perform its operations through the drm_v3d_extension struct. that's the flow, bestie — clean, direct, and lowkey iconic. ✨
