From f982cf4e9c37b19478c7bc6e0484a43a7e78cf57 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Thu, 15 May 2014 10:03:25 +0100 Subject: KVM: ARM: vgic: revisit implementation of irqchip_in_kernel So far, irqchip_in_kernel() was implemented by testing the value of vctrl_base, which worked fine with GICv2. With GICv3, this field is useless, as we're using system registers instead of a emmory mapped interface. To solve this, add a boolean flag indicating if the we're using a vgic or not.
