From 9fedf146778e6d1c26319ebaf56131a4f3a6be03 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Thu, 13 Nov 2014 16:21:35 +0000 Subject: arm/arm64: KVM: add opaque private pointer to MMIO data For a GICv2 there is always only one (v)CPU involved: the one that does the access. On a GICv3 the access to a CPU redistributor is memory-mapped, but not banked, so the (v)CPU affected is determined by looking at the MMIO address region being accessed. To allow passing the affected CPU into the accessors later, extend struct kvm_exit_mmio to add an opaque private pointer parameter. The current GICv2 emulation just does not use it.
