These are the last remining patches to enable dynamic allocation in gen8+. All credit to Ben's original design and Mika's extensive reviews. During stress testing, the light restore context corruption problem was observed in some systems (resubmission with HEAD==TAIL). The workaround to prevent to prevent this known problem should be in place as we also update the PDPx registers before the context is send to execution. The last patch is only of interest in systems with less than 4GB of memory. Now that the PPGTT table overhead is not that big, we can use the full virtual space address range in these systems.
