Summary:In one embodiment, a conflict detection logic is configured to receive a plurality of memory requests from an arbiter of a coherent fabric of a system on a chip (SoC). The conflict detection logic includes snoop filter logic to downgrade a first snooped memory request for a first address to an unsnooped memory request when an indicator associated with the first address indicates that the coherent fabric has control of the first address. Other embodiments are described and claimed.
