That's a userspace bug.

I915_GEM_GET_APERTURE ioctl is used to probe aperture size from userspace.
Some applications like OpenCL use this information to know how much GM
resource can it use. In gvt environment, each vm only use the ballooned
part of aperture, so we should return the actual aperture size exclude
the
