how can the gic600AE set interrupt router relationship by affility when the corresponded cores in DSU(such as A78AE) under lock step mode

I was building an interrupt system with GIC600AE for A78AE cpu, and i met a question that if i set the A78 cores in locked step mode, its affility attribute would changed, for example ,a cluster with...
