From bacf2c60548befa8a31c2f19ef65bf2177fda33f Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Wed, 4 Mar 2020 20:33:26 +0000 Subject: KVM: arm64: GICv4.1: Allow SGIs to switch between HW and SW interrupts In order to let a guest buy in the new, active-less SGIs, we need to be able to switch between the two modes. Handle this by stopping all guest activity, transfer the state from one mode to the other, and resume the guest. Nothing calls this code so far, but a later patch will plug it into the MMIO emulation.
