IAdapterPnpManagement::GetSupportedRebalanceType method (portcls.h)
The GetSupportedRebalanceType method returns the type of rebalancing supported. Rebalancing is used in certain Thunderbolt USB scenario, where, when additional devices are added to the USB chain, the use of memory resources needs to be rearranged and consolidated.
Syntax
PC_REBALANCE_TYPE GetSupportedRebalanceType();
Return value
The GetSupportedRebalanceType method returns the type of rebalancing supported (RebalanceNotSupported or RebalanceRemoveSubdevices) as defined in the enum PC_REBALANCE_TYPE.
Remarks
GetSupportedRebalanceType is called by Portcls while processing the QueryStop. Miniport returns the supported rebalance type.
Note Portcls acquires the device global lock before making this call, thus the miniport must execute this call as fast as possible.
