- Introduction LoongArch is the general processor architecture of Loongson. The following versions of the LoongArch core are supported core: 3A5000 https://github.com/loongson/LoongArch-Documentation/releases/download/2021.08.17/LoongArch-Vol1-v1.00-EN.pdf We can get the latest loongarch documents at https://github.com/loongson/LoongArch-Documentation/tags. - System emulation You can reference docs/system/loongarch/loongson3.rst to get the information about system emulation of LoongArch. - Linux-user emulation We already support Linux user emulation. We can use LoongArch cross-tools to build LoongArch executables on X86 machines, and We can also use qemu-loongarch64 to run LoongArch executables. 1. Config cross-tools env. see System emulation. 2. Test tests/tcg/multiarch. ./configure --static --prefix=/usr --disable-werror --target-list="loongarch64-linux-user" --enable-debug cd build make && make check-tcg 3. Run LoongArch system basic command with loongarch-clfs-system. - Config clfs env. wget https://github.com/loongson/build-tools/releases/download/2022.05.29/loongarch64-clfs-system-5.0.tar.bz2 tar -vxf loongarch64-clfs-system-5.0.tar.bz2 -C /opt/clfs cp /opt/clfs/lib64/ld-linux-loongarch-lp64d.so.1 /lib64 export LD_LIBRARY_PATH="/opt/clfs/lib64" - Run LoongArch system basic command. ./qemu-loongarch64 /opt/clfs/usr/bin/bash ./qemu-loongarch64 /opt/clfs/usr/bin/ls ./qemu-loongarch64 /opt/clfs/usr/bin/pwd - Note.
