Song Gao | 227e73c | 2022-06-24 11:10:49 +0800 | [diff] [blame] | 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 |
