Subject: [PATCH 0/3] target/arm: Add nested virtualization support
Date: Mon, 22 Mar 2021 10:07:23 +0000 [thread overview]
Message-ID: <cover.1616052889.git.haibo.xu@linaro.org> (raw)
This series add support for ARMv8.3/8.4 nested virtualization support
in KVM mode. It's based on Marc Zyngier's kernel KVM patches[1], and
has been tested on a FVP model to run a L2 guest with Qemu. Now the
feature can be enabled by "-M virt,accel=kvm,virtualization=on" when
starting a VM.
