From: Tvrtko Ursulin <tvrtko.ursu...@intel.com>
Currently only normal views were accounted which under-accounts
the usage as reported in debugfs.
Introduce new helper, i915_gem_obj_total_ggtt_size, and use it
from call sites which want to know how much GGTT space are
objects using.
v2: Single loop in i915_gem_get_aperture_ioctl. (Chris Wilson)
v3: Walk GGTT active/inactive lists in i915_gem_get_aperture_ioctl
for better efficiency. (Chris Wilson, Daniel Vetter)
v4: Make i915_gem_obj_total_ggtt_size private to debugfs. (Chris Wilson)
