Subject: [kvm-unit-tests PATCH] arm/run: Use TCG with qemu-system-arm on arm64 systems
Date: Thu, 17 Mar 2022 16:56:01 +0000	[thread overview]
Message-ID: <20220317165601.356466-1-alexandru.elisei@arm.com> (raw)

From: Andrew Jones <drjones@redhat.com>

If the user sets QEMU=qemu-system-arm on arm64 systems, the tests can only
be run by using the TCG accelerator. In this case use TCG instead of KVM.
