From d3eb47a2a18f850c2ebd20e50d164251ad321128 Mon Sep 17 00:00:00 2001 From: Cédric Le Goater Date: Mon, 25 Nov 2019 07:58:08 +0100 Subject: ppc/xive: Introduce a XiveFabric interface The XiveFabric QOM interface acts as the PowerBUS interface between the interrupt controller and the system and should be implemented by the QEMU machine. On HW, the XIVE sub-engine is responsible for the communication with the other chip is the Common Queue (CQ) bridge unit. This interface offers a 'match_nvt' handler to perform the CAM line matching when looking for a XIVE Presenter with a dispatched NVT.
