Print map for total physical and virtual memory

Print map for total physical and virtual memory

[Pankaj Suryawanshi]

Hello,

1. Is there any way to print whole physical and virtual memory map in kernel/user space ?

2. Is there any way to print map of cma area reserved memory and movable pages of cma area.

3. Is there any way to know who pinned the pages from cma reserved area ?


Regards,
Pankaj

... you should probably use gmail or something.  Whatever broken email
system your employer provides makes it really hard for you to participate
in any meaningful way.

> Can you please elaborate about tools/vm/page-types.c ?

cd tools/vm/
make
sudo ./page-types

If that doesn't do exactly what you need, you can use the source code to
make a program which does.
