Loongson-3 CPU family include Loongson-3A R1/R2/R3/R4 and Loongson-3B
R1/R2. 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.

User Manual Part 2:
I'm sorry that it is unavailable now.
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 <path_to_kernel> -append ...
Use QEMU with KVM:
qemu-system-mips64el -M loongson3-virt,accel=kvm -cpu Loongson-3A4000 -kernel <path_to_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 <aleksandar.qemu.devel@gmail.com>.
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).
Huacai Chen and Jiaxun Yang (6):
linux-headers: Update MIPS KVM type defintition
target/mips: Fix PageMask with variable page size
target/mips: Add loongson-ext lswc2 group of instructions (Part 1)
target/mips: Add loongson-ext lswc2 group of instructions (Part 2)
target/mips: Add loongson-ext lsdc2 group of instructions
hw/mips: Add Loongson-3 machine support

Can you add a KVM-only build CI job?
Simply building, not running test, as there is no MIPS CI.
See for example commit 41e1f0e2256 (".travis.yml: Add a KVM-only
s390x job"), but add it to GitLab instead.
Thanks!
Phil.
