Loongson-3A R1 is the oldest and its ISA is the smallest, while Loongson-3A R4 is the newest and its ISA is almost the superset of all others. To reduce complexity, in QEMU we just define two CPU types: 1, "Loongson-3A1000" CPU which is corresponding to Loongson-3A R1. It is suitable for TCG because Loongson-3A R1 has fewest ASE. 2, "Loongson-3A4000" CPU which is corresponding to Loongson-3A R4. It is suitable for KVM because Loongson-3A R4 has the VZ ASE. Loongson-3 lacks English documents. I've tried to translated them with translate.google.com, and the machine translated documents (together with their original Chinese versions) are available here.

And human-translated documents (W.I.P) are available here now: https://github.com/loongson-community/docs/tree/master/English-translation-of-Loongson-manual Both KVM and TCG are available now! We now already have a full functional Linux kernel (based on Linux-5.4.x LTS, the kvm host side and guest side have both been upstream for Linux- 5.9, but Linux-5.9 has not been released yet) here: https://github.com/chenhuacai/linux Of course the upstream kernel is also usable (though it is "unstable" now): https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git How to use QEMU/Loongson-3? 1, Download kernel source from the above URL; 2, Build a kernel with arch/mips/configs/loongson3_{def,hpc}config; 3, Boot a Loongson-3A4000 host with this kernel (for KVM mode); 4, Build QEMU-master with this patchset; 5, modprobe kvm (only necessary for KVM mode); 6, Use QEMU with TCG: qemu-system-mips64el -M loongson3-virt,accel=tcg -cpu Loongson-3A1000 -kernel -append ... Use QEMU with KVM: qemu-system-mips64el -M loongson3-virt,accel=kvm -cpu Loongson-3A4000 -kernel -append ... The "-cpu" parameter is optional here and QEMU will use the correct type for TCG/KVM automatically. V1 -> V2: 1, Add a cover letter; 2, Improve CPU definitions; 3, Remove LS7A-related things (Use GPEX instead); 4, Add a description of how to run QEMU/Loongson-3. V2 -> V3: 1, Fix all possible checkpatch.pl errors and warnings. V3 -> V4: 1, Sync code with upstream; 2, Remove merged patches; 3, Fix build failure without CONFIG_KVM; 4, Add Reviewed-by: Aleksandar Markovic . V4 -> V5: 1, Improve coding style; 2, Remove merged patches; 3, Rename machine name from "loongson3" to "loongson3-virt"; 4, Rework the "loongson3-virt" machine to drop any ISA things; 5, Rework "hw/mips: Implement the kvm_type() hook in MachineClass"; 6, Add Jiaxun Yang as a reviewer of Loongson-3. V5 -> V6: 1, Fix license preamble; 2, Improve commit messages; 3, Add hw/intc/loongson_liointc.c to MAINTAINERS; 4, Fix all possible checkpatch.pl errors and warnings. V7 and V8 have only one patch (machine definition) with some minor improvements. V8 -> V9: 1, Update KVM type definition from kernel; 2, Fix PageMask with variable page size for TCG; 3, Add TCG support (add Loongson-EXT instructions). V9 -> V10: 1, Split fw_cfg to a separate patch; 2, Split boot parameters definition to a local header; 3, Update MIPS machine documentation; 4, Many other improvements suggested by Philippe Mathieu-Daudé. V10 -> V11: 1, Fix some typos; 2, Add Reviewed-by: Philippe Mathieu-Daudé . V11 -> V12: 1, Split boot parameter helpers to loongson3_bootp.c; 2, Support both BE and LE host (Loongson guests are always LE).
