hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IA7L2U --------------------------- If the chip not having RDT function, resctrl_arch_system_num_rmid_idx() would return 0. rmid_ptrs points to an illegal buffer after kcalloc() allocation, which would cause illegal access fault when accessing. Consequently, when we found resctrl_arch_system_num_rmid_idx() return 0, just return EOPNOTSUPP immediatly and skip initializing the resctrl file system.
