To perform this, the slave ports of the coherent bus are wrapped in internal master ports that are passed as the source ports to the response layer in question. As a result of this patch, there is more contention for the response resources, and as such system performance will decrease slightly. A consequence of the mirrored internal port is that the port the bus tells to retry (the internal one) and the port actually retrying (the mirrored) one are not the same. Thus, the existing check in tryTiming is not longer correct. In fact, the test is redundant as the layer is only in the retry state while calling sendRetry on the waiting port, and if the latter does not immediately call the bus then the retry state is left. Consequently the check is removed. |
