Subject: [PATCH v5 0/7] target/riscv: Expose RV32 cpu to RV64 QEMU
Date: Wed, 10 Jul 2024 10:24:23 +0800 [thread overview]
Message-ID: <20240710022430.1306-1-zhiwei_liu@linux.alibaba.com> (raw)
From: 甲一 <lzw194868@alibaba-inc.com>
This patch set aims to expose 32-bit RISC-V cpu to RV64 QEMU. Thus
qemu-system-riscv64 can directly boot a RV32 Linux.
This patch set has been tested with 6.9.0 Linux Image.
And add an avocado test in tests/avocado.
