hw/riscv: virt: Allow creating multiple NUMA sockets
We extend RISC-V virt machine to allow creating a multi-socket machine. Each RISC-V virt machine socket is a NUMA node having a set of HARTs, a memory instance, a CLINT instance, and a PLIC instance. Other devices are shared between all sockets. We also update the generated device tree accordingly. By default, NUMA multi-socket support is disabled for RISC-V virt machine. To enable it, users can use "-numa" command-line options of QEMU. Example1: For two NUMA nodes with 2 CPUs each, append following to command-line options: "-smp 4 -numa node -numa node" Example2: For two NUMA nodes with 1 and 3 CPUs, append following to command-line options: "-smp 4 -numa node -numa node -numa cpu,node-id=0,core-id=0 \ -numa cpu,node-id=1,core-id=1 -numa cpu,node-id=1,core-id=2 \ -numa cpu,node-id=1,core-id=3" The maximum number of sockets in a RISC-V virt machine is 8 but this limit can be changed in future.
