[PATCH OLK-6.6] arm64/mpam: Fix L2 MBWU monitor multiplexing issue
by Zeng Heng 27 Oct '25

27 Oct '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID29QH -------------------------------- The MBWU monitor performs long-term cumulative statistics on bandwidth for a specified PARTID. However, the number of L2 physical monitors is very limited. To support the expanded quantities of PARTIDs and PMGs, the MBWU monitors need to multiplex. Therefore, when a monitor tracks a new PARTID or PMG, which means a change in monitor configuration is detected, the accumulated correction should set to zero.
