Review request for Default. Repository: gem5 Description ------- Changeset 11291:a6168c5472d6 --------------------------- mem: Align how snoops are handled when hitting writebacks This patch unifies the snoop handling in case of hitting writebacks with how we handle snoops hitting in the tags. As a result, we end up using the same optimisation as the normal snoops, where we inform the downstream cache if we encounter a line in Modified (writable and dirty) state, which enables us to avoid sending out express snoops to invalidate any Shared copies of the line. A few regressions consequently change, as some transactions are sunk higher up in the cache hierarchy.
