You can enable ARM_PTDUMP when building the Linux kernel so the kernel page
tables can be dumped out, for user space you can check '/proc/pid/pagemap'.

Hi there,
I wanna try to categorize each memory references (physical address) to system
references, user references and shared-library references. System references
means that those references will access to OS code or data, shared-library
references means that those references will access to shared binary libraries,
and so on. However, I don't know how to distinguish them. Are there any files
that records how the virtual address of each process is mapped?
FYI, I found from google that the /proc/[pid]/maps file stored mapping
information for each process, but I only found from those files that 1) the
virtual pape distribution rather than VA->PA mapping; 2) some shared library,
and syscall mapping but no OS kernel code or data mapping.
Could anybody tell me how to find that kind of information from gem5, for
example, what should I do to find which physical pages are arranged to store OS
kernel or data, which pages are arranged for application code or data?
Thanks very much.
