i915_gem_ob...e_shrinkable(9)

🦋 i915_gem_ob...e_shrinkable(9) 🦋

okay bestie, welcome to the Kernel API Manual ✨ this one's a lil page about a function with a name so long the header literally had to abbreviate it — i915_gem_ob...e_shrinkable(9) — and honestly? iconic of it 💅

---

🌸 NAME 🌸

i915_gem_object_make_shrinkable — so what it does is, it moves the object to the tail of the shrinkable list 🎀 and like, heads up: objects on this list might be swapped out 😭 it's used with WILLNEED objects, iykyk.

---

✨ SYNOPSIS ✨

void i915_gem_object_make_shrinkable (struct drm_i915_gem_object *obj );

that's it, that's the whole vibe — returns void, takes one pointer, no cap 🫶

---

🧚 ARGUMENTS 🧚

• obj — the GEM object. yes. that's the whole description. she's brief, she's mysterious, she's a GEM object 💖

---

👑 DESCRIPTION 👑

ok so this is where the rules live, and they're lowkey strict, so listen up 🔥

MUST only be called on objects which have backing pages. like, fr fr. no pages, no call. 🚫

and it MUST be balanced with a previous call to i915_gem_object_make_unshrinkable — you can't just make it shrinkable and dip, bestie, that's not how this works 😤 it's giving "every action has an equal and opposite reaction" but for kernel objects ✨
