Subject: [PATCH v21 1/6] hw/arm/virt: Introduce a RAS machine option
Date: Mon, 4 Nov 2019 20:14:53 +0800	[thread overview]
Message-ID: <20191104121458.29208-2-zhengxiang9@huawei.com> (raw)
In-Reply-To: <20191104121458.29208-1-zhengxiang9@huawei.com>

From: Dongjiu Geng <gengdongjiu@huawei.com>

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