In structure CPUArchState some struct elements are only used in TCG mode, and it is not used in KVM mode. Macro CONFIG_TCG is added to make it simpiler in KVM mode, also there is the same modification in c code when these structure elements are used. When VM runs in KVM mode, TLB entries are not used and do not need migrate. It is only useful when it runs in TCG mode.

- 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.
