1 - Introduction 2 3 LoongArch is the general processor architecture of Loongson. 4 5 The following versions of the LoongArch core are supported 6 core: 3A5000 7 https://github.com/loongson/LoongArch-Documentation/releases/download/2021.08.17/LoongArch-Vol1-v1.00-EN.pdf 8 9 We can get the latest loongarch documents at https://github.com/loongson/LoongArch-Documentation/tags. 10 11 12 - System emulation 13 14 You can reference docs/system/loongarch/loongson3.rst to get the information about system emulation of LoongArch. 15 16 - Linux-user emulation 17 18 We already support Linux user emulation. We can use LoongArch cross-tools to build LoongArch executables on X86 machines, 19 and We can also use qemu-loongarch64 to run LoongArch executables. 20 21 1. Config cross-tools env. 22 23 see System emulation. 24 25 2. Test tests/tcg/multiarch. 26 27 ./configure --static --prefix=/usr --disable-werror --target-list="loongarch64-linux-user" --enable-debug 28 29 cd build 30 31 make && make check-tcg 32 33 3. Run LoongArch system basic command with loongarch-clfs-system. 34 35 - Config clfs env. 36 37 wget https://github.com/loongson/build-tools/releases/download/2022.05.29/loongarch64-clfs-system-5.0.tar.bz2 38 39 tar -vxf loongarch64-clfs-system-5.0.tar.bz2 -C /opt/clfs 40 41 cp /opt/clfs/lib64/ld-linux-loongarch-lp64d.so.1 /lib64 42 43 export LD_LIBRARY_PATH="/opt/clfs/lib64" 44 45 - Run LoongArch system basic command. 46 47 ./qemu-loongarch64 /opt/clfs/usr/bin/bash 48 ./qemu-loongarch64 /opt/clfs/usr/bin/ls 49 ./qemu-loongarch64 /opt/clfs/usr/bin/pwd 50 51 - Note. 52 We can get the latest LoongArch documents or LoongArch tools at https://github.com/loongson/
