The number of memory banks in QEMU is not bounded by 1. In this example we have two banks: qemu-system-riscv64 \ -machine virt \ -nographic \ -m 8192 \ -smp 8,sockets=2,cores=4,threads=1 \ -numa node,cpus=0-3,mem=4096 \ -numa node,cpus=4-7,mem=4096 \ -kernel u-boot As we will see RISC-V NUMA systems using U-Boot we should be able to emulate these. Use the default value defined in /Kconfig as 4.
