Hi, everyone

I have 2 memory nodes in my NUMA system.
I want to know the start (physical and virtual) address of each memory node. How can I do?

Please give me any hint...

Thanks in advance

My embedded system says no numa configuration information through kernel message.
Is there other methods?

If I trace the data structure "pg_data_t *pgdat = NODE_DATA(nid)", can I find out the information of start address in each nodes? Is there simple way rather than searching the kernel MM source code?

Thanks

Are you sure your hardware is in fact NUMA?

Did you build your kernel with NUMA support?

And are you just curious what the configuration is, or does it actually
make a difference for some reason?
