[PATCH for-5.0 v5 08/23] ppc/xive: Introduce a XivePresenter interface

2019-11-15 Thread Cédric Le Goater
When the XIVE IVRE sub-engine (XiveRouter) looks for a Notification Virtual Target (NVT) to notify, it broadcasts a message on the PowerBUS to find an XIVE IVPE sub-engine (Presenter) with the NVT dispatched on one of its HW threads, and then forwards the notification if any response was received.
