From 5e91b9e03f6cbb0f8333e60422ef44c15b4775c7 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 23 Dec 2022 10:01:07 +0100 Subject: [PATCH] hw/arm/virt: Make accels in GIC finalize logic explicit MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Let's explicitly list out all accelerators that we support when trying to determine the supported set of GIC versions. KVM was already separate, so the only missing one is HVF which simply reuses all of TCG's emulation code and thus has the same compatibility matrix.
