Add a DMA thread tester to the Ruby GPU tester to test the DMA state
machine in the protocol. Currently creates a dummy DMA device to pass
through Ruby.py and scans for the DMA sequencers due to opaqueness of
Ruby.py.
DMA atomics not yet supported as there is no protocol that implements
atomic transitions in the DMA state machine file.
Example run command:
build/GCN3_X86/gem5.opt configs/example/ruby_gpu_random_test.py \
--test-length=1000

This patch adds the GPU protocol tester that uses data-race-free
operation to discover bugs in GPU protocols including GPU_VIPER. For
