Hello everyone, I am working in gem5 version 22.0, I wan to design a cache replacement policy as a part of my research work, which evicts blocks based on the contents i.e. considering a number of zeros and ones. Is there a possibility to get the content of cache blok, in gem5? Thanks and Regards, Sadhana, Research Scholar-NITK, Dept. of Computer Science and Engineering .

Hey Sadhana, First of i'll i'd read over the replacement policy documentation: https://www.gem5.org/documentation/general_docs/memory_system/replacement_policies/. There are lot of options to get information on a cache blog. Generally I think this Stackoverflow gives the most comprehensive options on this: https://stackoverflow.com/questions/64954075/how-to-output-the-data-in-the-cache-set-when-the-cache-is-replaced. The most important thing to to keep in mind in the `CacheBlk->data` will always get you the data in the cache block (it's a `uint8_t*`). I don't know exactly what the options are here but they may be a debug flag that gets you what you want. For more information on using debug flags: https://www.gem5.org/documentation/learning_gem5/part2/debugging/. Kind regards, Bobby -- Dr. Bobby R.
