There was a bug exposed by a recent PR [1] where until recently the O3 CPU was executing an instruction even if it did not have the required functional unit in the FU pool. We are adding the crypto descriptors to the Default FU pool in the O3 cpu so that no panic is encountered upon executing of a crypto instruction [1]: https://github.com/gem5/gem5/pull/1516 Change-Id: Ifaf2f8e4780dfb8ba825a99a02dd587f011dbd23 Reviewed-by: Richard Cooper <richard.cooper@arm.com> Signed-off-by: Giacomo Travaglini <giacomo.travaglini@arm.com>
