drm_gem_obj...memory_stats(9)

💅 drm_gem_obj...memory_stats(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes, the whole entire manual, and today's main character is this one tiny little boolean function that's honestly kind of a vibe. pull up a chair 🎀

---

✨ NAME ✨

drm_gem_object_is_shared_for_memory_stats — the helper for shared memory stats, that's literally her job description, no cap 💖

---

🌸 SYNOPSIS 🌸

bool drm_gem_object_is_shared_for_memory_stats (struct drm_gem_object
*obj );

it returns a bool, she takes a struct drm_gem_object *obj, and the call is drm_gem_object_is_shared_for_memory_stats. that's it. that's the whole synopsis. slay 💅

---

🦋 ARGUMENTS 🦋

• obj — the obj in question 👀 like, the actual struct drm_gem_object * you're asking about. that's the one. she's the subject of the investigation, periodt.

---

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ — this helper should only be used for fdinfo shared memory stats. only. exclusively. that's her whole lane and she is not leaving it 🫶

her entire purpose is to determine if a GEM object is shared. is it shared? is it not shared? she returns a bool and lets you know. that's the function. iconic behaviour, honestly.

bestie pls don't repurpose her for something else 😭 she is specifically the fdinfo shared memory stats helper, and the manpage is very clear about that. respect her boundaries fr fr.
