How far > can the amount of memory on the unevictable list and the amount > displayed in this "bound objects" value diverge? Those non-shmemfs objects would not show up on the unevictable list. On typical use case, The size of gtt bounded objects (in unevictable list) is very close to the bound size in i915_gem_objects. E.g. on my laptop: i915_gem_object shows 110075904 bytes bounded objects, and there are 109760512 bytes gtt bounded objects, the difference is about 0.3%.
