(Updated June 24, 2014, 11:26 p.m.) Review request for Default. Repository: gem5 Description ------- Changeset 10243:8f4099f6b9a2 --------------------------- mem: re-factor LRU code and add random replacement cache tags this patch implements a new tags class that uses a random replacement policy. these tags prefer to evict invalid blocks first, if none are available a replacement candidate is chosen at random. this patch factors out the common code in the LRU class and creates a new abstract class: the BaseLRU class. any LRU tag or derivative of LRU must implement the methods related to the actual replacement policy. these are the following methods, which are pure virtual methods in BaseLRU: accessBlock() findVictim() insertBlock() invalidate() Diffs ----- src/mem/cache/base.cc cb4e86c177672fde6be7a409793c944e36353fc0 src/mem/cache/cache.cc cb4e86c177672fde6be7a409793c944e36353fc0 src/mem/cache/tags/SConscript cb4e86c177672fde6be7a409793c944e36353fc0 src/mem/cache/tags/Tags.py cb4e86c177672fde6be7a409793c944e36353fc0 src/mem/cache/tags/base_lru.hh PRE-CREATION src/mem/cache/tags/base_lru.cc PRE-CREATION src/mem/cache/tags/lru.hh cb4e86c177672fde6be7a409793c944e36353fc0 src/mem/cache/tags/lru.cc cb4e86c177672fde6be7a409793c944e36353fc0 src/mem/cache/tags/pseudo_lru.hh PRE-CREATION src/mem/cache/tags/pseudo_lru.cc PRE-CREATION Diff: http://reviews.gem5.org/r/2167/diff/ Testing (updated) ------- Regressions pass Thanks, Anthony Gutierrez _______________________________________________ gem5-dev mailing list [email protected] http://m5sim.org/mailman/listinfo/gem5-dev
