From 5a2ae2350e78cfdc7ca9885b8c3d62137115a494 Mon Sep 17 00:00:00 2001 From: LIU Zhiwei Date: Thu, 20 Jan 2022 20:20:48 +0800 Subject: [PATCH] target/riscv: Set default XLEN for hypervisor When swap regs for hypervisor, the value of vsstatus or mstatus_hs should have the right XLEN. Otherwise, it will propagate to mstatus.
