💅 drm_syncobj_open(9)

okay bestie, welcome to the Kernel API Manual — this one's about drm_syncobj_open(9) and it's literally the setup queen of the syncobj world. buckle up 🎀

✨ NAME ✨

drm_syncobj_open — initializes syncobj file-private structures at devnode open time 🦋

🌸 SYNOPSIS 🌸

void drm_syncobj_open (struct drm_file *file_private );

🎀 ARGUMENTS 🎀

• file_private — the drm file-private structure we're gonna set up. that's the one, that's the whole assignment 💅

💖 DESCRIPTION 💖

So here's the vibe: this gets called at device open time, and what it does is set up the structure for handling refcounting of sync objects. that's it, that's the job. it's giving "quiet but essential" — no cap, the whole sync object refcount situation lowkey depends on this happening at open time. iconic. ✨
