This file is a required input to the simulator for GPUFS. There seems to be confusion from several users who are not providing this input. This usually results in the amdgpu driver failing to load, leading to the application under test exiting along with it. This changeset adds a simple md5 hashsum check to compare against the known good MMIO trace located in the gem5-resources repository.
