Subject: [PATCH 2/4] target/riscv: Remove check on mode for MPRV
Date: Mon, 29 May 2023 20:17:17 +0800 [thread overview]
Message-ID: <20230529121719.179507-3-liweiwei@iscas.ac.cn> (raw)
In-Reply-To: <20230529121719.179507-1-liweiwei@iscas.ac.cn>
Normally, MPRV can be set to 1 only in M mode (It will be cleared
when returning to lower-privilege mode by MRET/SRET).
