Systems and methods for translating cache hints between different protocols within a SoC. A requesting agent within the SoC generates a first cache hint for a transaction, and the first cache hint is compliant with a first protocol. The first cache hint can be set to a reserved encoding value as defined by the first protocol. Prior to the transaction being sent to the memory subsystem, the first cache hint is translated into a second cache hint. The memory subsystem recognizes cache hints which are compliant with a second protocol, and the second cache hint is compliant with the second protocol.
