From 6277579778d63125671509e2502597fdf6a56c00 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Fri, 27 Oct 2017 15:28:50 +0100 Subject: KVM: arm/arm64: GICv4: Hook vPE scheduling into vgic flush/sync The redistributor needs to be told which vPE is about to be run, and tells us whether there is any pending VLPI on exit. Let's add the scheduling calls to the vgic flush/sync functions, allowing the VLPIs to be delivered to the guest.
