(Updated Aug. 21, 2015, 3:47 p.m.) Review request for Default. Repository: gem5 Description (updated) ------- Changeset 11061:3b40b2d9e2d8 --------------------------- mem: Add snoops for CleanEvicts and Writebacks in atomic mode This patch mirrors the logic in timing mode which sends up snoops to check for cached copies before sending CleanEvicts and Writebacks down the memory hierarchy. In case there is a copy in a cache above, discard CleanEvicts and set the BLOCK_CACHED flag in Writebacks so that writebacks do not reset the cache residency bit in the snoop filter below.
