Add Loongson-3 based machine support, it use liointc as the interrupt controler and use GPEX as the pci controller. Currently it can work with both TCG and KVM. As the machine model is not based on any exiting physical hardware, the name of the machine is "loongson3-virt". It may be superseded in future by a real machine model. If this happens, then a regular deprecation procedure shall occur for "loongson3-virt" machine. We now already have a full functional Linux kernel (based on Linux-5.4.x LTS) here: https://github.com/chenhuacai/linux Of course the upstream kernel is also usable (the kvm host side and guest side have both been upstream in Linux-5.9): 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_defconfig; 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.
