In a computer with two CPUs, how can I get the physical address of local memory of each CPU?

My computer has the following specifications - 2 Intel CPU x86_64 - Total 8GB memory (4GB per CPU) - O/S is Rocky Linux 9 I want to reserve 1GB of memory per CPU using the memmap parameter in grub. I checked dmesg and /proc/meminfo and even used numaclt -H. But I couldn't find the physical address of the memory for each CPU. How can I get physical addresses of local memory of each CPU?
