Subject: [PATCH v3 0/6] Add loongarch32 mode for loongarch64-softmmu
Date: Mon, 7 Aug 2023 17:44:59 +0800 [thread overview]
Message-ID: <20230807094505.2030603-1-c@jia.je> (raw)
This patch series allow qemu-system-loongarch64 to emulate a LoongArch32
machine. A mode enum is added to CPUArchState to select LA32 or LA64 at
runtime. A new CPU model is added for loongarch32. Initial GDB support
is added.
Changes since v2:
- Fix typo in previous commit
- Fix VPPN width in TLBEHI/TLBREHI
Changes since v1:
- No longer create a separate qemu-system-loongarch32 executable, but
allow user to run loongarch32 emulation using qemu-system-loongarch64
- Add loongarch32 cpu support for virt machine
