Subject: [PATCH v22 1/9] hw/arm/virt: Introduce a RAS machine option
Date: Wed, 8 Jan 2020 19:32:15 +0800
Message-ID: <1578483143-14905-2-git-send-email-gengdongjiu@huawei.com> (raw)
In-Reply-To: <1578483143-14905-1-git-send-email-gengdongjiu@huawei.com>

RAS Virtualization feature is not supported now, so add a RAS machine
option and disable it by default.
