[Intel-gfx] [PATCH] drm/i915/gt: Clear LOCAL_BIND from shared GGTT on resume

[Intel-gfx] [PATCH] drm/i915/gt: Clear LOCAL_BIND from shared GGTT on resume

[Chris Wilson]

We only restore GLOBAL binds upon resume as we expect these to be pinned
for use by HW, whereas the LOCAL binds can be recreated on demand once
userspace is resumed. For the LOCAL bind to be recreated in the global
GTT, we need to clear its presence flag on deciding not to restore the
mapping upon resume.
