Cache Corruption by Gem5

      I need to access data in cache and manipulate it for injecting fault into application. I am working on the research project about fault tolerance in hpc and need to observe cache level data . I would like to get your help and your suggestion about it. I will be grateful if you can help me?

You can start by looking at the cache code in src/mem/cache. It should be pretty obvious where the data is stored (e.g., see line 77 in cache.hh). If you wanted to randomly corrupt some data, you could add a new event that fires at a random interval and chooses a block to corrupt, as an example.

Hopefully this gets you started on the right path.
