Subject: [PATCH 3/8] target/riscv: Remove check on RVH for riscv_cpu_virt_enabled
Date: Fri, 24 Mar 2023 20:38:04 +0800 [thread overview]
Message-ID: <20230324123809.107714-4-liweiwei@iscas.ac.cn> (raw)
In-Reply-To: <20230324123809.107714-1-liweiwei@iscas.ac.cn>
Since env->virt.VIRT_ONOFF is initialized as false, and will not be set
to true when RVH is disabled, so we can just return this bit(false) when
RVH is not disabled.
