💅 i915_gem_ob...unshrinkable(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for i915_gem_object_make_unshrinkable, and honestly the name is longer than my attention span but we're gonna get through it together 🫶

---

✨ NAME ✨

i915_gem_object_make_unshrinkable — literally hides the object from the shrinker 👀

ngl the deets matter here: by default, all object types that support shrinking (see IS_SHRINKABLE) will also make the object visible to the shrinker after allocating the system memory pages. so this function is the "not me, not today" button for that 💅

---

🎀 SYNOPSIS 🎀

void i915_gem_object_make_unshrinkable (struct drm_i915_gem_object *obj);

that's it. that's the whole vibe check. returns void because it's not here to give you answers 💀

---

🌸 ARGUMENTS 🌸

• obj — the GEM object 🦋 (yes, that's the whole description, she's lowkey mysterious like that)

---

🧚 DESCRIPTION 🧚

so like, this is typically used for special kernel internal objects that can't be easily processed by the shrinker — think objects that are perma-pinned 👑 they just live there, rent free, and the shrinker can't do anything with them, so we make them unshrinkable and everybody moves on. iconic behavior, no cap ✨
