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 | |
