💅 drm_syncobj_find(9) — the Kernel API Manual, but make it make sense

okay so this is from the Kernel API Manual, section 9, and it's literally the page for drm_syncobj_find. bestie, it's short, it's sweet, and it's lowkey the key to the whole syncobj kingdom. let's get into it ✨

🌸 NAME 🌸

drm_syncobj_find — lookup and reference a sync object. that's it. that's the vibe check. you hand it a handle, it hands you the syncobj. 💫

✨ SYNOPSIS ✨

struct drm_syncobj * drm_syncobj_find (struct drm_file *file_private ,
       u32 handle );

like, the whole function is one line and it's giving main character energy fr fr 🫶

🎀 ARGUMENTS 🎀

  • file_private — the drm file private pointer, aka the little personal context blob for this DRM file. ngl it's just the file's own private lil world 🙈
  • handle — the sync object handle to lookup. this is the thing you're asking about, the little ID ticket you're presenting at the door 🎟️

💖 DESCRIPTION 💖

so what actually happens? you give it a handle, and it returns a reference to the syncobj that handle points to — or NULL. that's it. no cap. 🔥

⚠️ the part you cannot skip, bestie: that reference is yours now, and you must release it by calling drm_syncobj_put. do not abandon it. do not ghost it. it will not be cute. 😭

like honestly it's giving "borrow my hoodie but give it back" energy — the lookup is the borrow, drm_syncobj_put is the return. periodt. 💅
