To do so, we define SD_WORKLOAD_CONSOLIDATION, and add some fields in sched_domain struct: 1) total_groups is the group number in total in this domain 2) group_number is this CPU's group sequence number 3) consolidating_coeff is the coefficient for consolidating CPUs, and is changeable via sysctl tool to make consolidation more aggressive or less 4) first_group is the pointer to this domain's first group ordered by CPU number This patchset enables SD_WORKLOAD_CONSOLIDATION in MC domain by default. But we need to come up with a better way to determine on which architecture this flag should be enabled or not. Thanks to PeterZ and Dietmar for pointing this out and help me finally understand it.
