Song Gao227e73c2022-06-24 11:10:49 +080016- 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
