Now we can't create a VZ guest in QEMU because it lacks the kvm_type() hook in MachineClass. Besides, libvirt uses a null-machine to detect the kvm capability, so by default it will return "KVM not supported" on a VZ platform. Thus, null-machine also need the kvm_type() hook.

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, 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-3A has CONFIG6 and CONFIG7, so add their bit-fields as well.

Currently it can only work with KVM, but we will add TCG support in future. We already have a full functional Linux kernel (based on Linux-5.4.x LTS but not upstream yet) here: https://github.com/chenhuacai/linux 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 the a Loongson-3A4000 host with this kernel; 4, Build QEMU-5.0.0 with this patchset; 5, modprobe kvm; 6, Use QEMU with TCG (available in future): qemu-system-mips64el -M loongson3,accel=tcg -cpu Loongson-3A1000 -kernel -append ... Use QEMU with KVM (available at present): qemu-system-mips64el -M loongson3,accel=kvm -cpu Loongson-3A4000 -kernel -append ... The "-cpu" parameter can be omitted here and QEMU will use the correct type for TCG/KVM automatically.
