Hello, I m trying to find out whether the kernel represents somehow the organization of the main memory in finer granularity than memory nodes, e.g. DIMMS, DRAM devices, etc. I understand that information about physical memory in architectures like ARM64 might be provided as part of the DTS and overriden by the bootloader but I couldn't find if/how that level of information is kept in the kernel after booting. Also, I took a look in the code related to memory hotplugging, assuming that there would be some information there regarding whether a DIMM is online or offline, but this didn't help either. Any directions on where to look? Babis
