Will you implement update_mba_bw() for AMD in future? > list_for_each_entry(crgrp, head, mon.crdtgrp_list) > mbm_update(d, crgrp->mon.rmid); > > - if (is_mba_sc(NULL)) > - update_mba_bw(prgrp, d); > + if (is_mba_sc(NULL)) { > + r_mba = &rdt_resources_all[RDT_RESOURCE_MBA]; > + if (r_mba->update_mba_bw) > + r_mba->update_mba_bw(prgrp, d); > + } Mount option "mba_MBps" is not implemented on AMD. Then don't call set_mba_sc(true) in parse_rdtgroupfs_options(). Thus, you don't need to change this code here because is_mba_sc(NULL) is false on AMD. Thanks. -Fenghua
