Dear All, The GPU_RfO and GPU_VIPER_Region protocol were part of the gem5 v20.1.0.5 <https://gem5.googlesource.com/public/gem5/+/refs/tags/v20.1.0.5/src/mem/ruby/protocol/> but were removed from v21.0.0.0 <https://gem5.googlesource.com/public/gem5/+/refs/tags/v21.0.0.0/src/mem/ruby/protocol/> onwards. The removal of these protocols is not mentioned in the release notes <https://gem5.googlesource.com/public/gem5/+/refs/tags/v21.0.0.0/RELEASE-NOTES.md> . I had a few queries: a) Are these protocols merged into other protocols or deprecated? b) Can we port the Ruby and SLICC state machine files for GPU_RfO and the Viper protocol to a newer version of Gem5? What engineering challenges need to be addressed?
Regards, Vipin
