CDP extends CAT and provides the capacity to control L3 code & data cache. With CDP, one COS correspond to two CMBs(code & data). cbm_type is added to support distinguish different CBM operation. Besides, new domctl cmds are introdunced to support set/get CDP CBM. Some CAT functions to operation CB
