I've posted details on how to set up test configurations using injected HMAT and SRAT tables here: https://github.com/rzwisler/hmat_examples So far I've got two different sample configs, and we can add more as they are useful. Having the sample configs in github is also nice because if someone finds a config that causes a kernel issue it can be reported then added to this list of example configs for future testing. Please let me know if you have trouble getting this working.
