panfrost_copy_in_sync(9)

💖 panfrost_copy_in_sync 💖

okay so bestie, welcome to the Kernel API Manual — yes, we're in kernel land now, and yes, this page is gonna be cute and correct ✨

---

🌸 NAME 🌸

panfrost_copy_in_sync — sets up job->deps with the sync objects that the job references 🫶

---

🎀 SYNOPSIS 🎀

int panfrost_copy_in_sync (struct drm_device *dev , struct drm_file
*file_priv , struct drm_panfrost_submit *args , struct panfrost_job *job
);

literally that's the whole signature, no cap 💅

---

🦋 ARGUMENTS 🦋

• dev — the DRM device, the main character of this whole thing 👑
• file_priv — the DRM file for this fd, iykyk 🌈
• args — the IOCTL args, coming in hot from userspace 🔥
• job — the job being set up, our little project 🎀

---

⭐ DESCRIPTION ⭐

So what this icon actually does: it resolves the syncobjs coming from userspace into fences, and then attaches them to job. Obsessed with the efficiency honestly ✨

💀 heads up: this function does not need to unreference the fences on failure — that cleanup happens later, at panfrost_job_cleanup time. so like, don't stress about that here, it's handled 🙈
