From 0919e84c0fc1fc73525fdcedefab89ea8460f697 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Thu, 26 Nov 2015 17:19:25 +0000 Subject: KVM: arm/arm64: vgic-new: Add IRQ sync/flush framework Implement the framework for syncing IRQs between our emulation and the list registers, which represent the guest's view of IRQs. This is done in kvm_vgic_flush_hwstate and kvm_vgic_sync_hwstate, which gets called on guest entry and exit. The code talking to the actual GICv2/v3 hardware is added in the following patches.
