Using PIN to get physical memory address

[morca]

Is it possible to get physical address accesses of a program with the help of PIN? I didn't see related things in the document

Can someone shed a light on that?

Assume there is a memory instruction and it is going to load something. An address is generated and I want to record that. At application level, the address is virtual, but the at the end of the day, there should be a physical address for cache/memory lookup.

I found this topic, but didn't found anything more than that.

In Linux systems there is an interface that a user process can use to convert from Virtual to Physical addresses:  /proc/self/pagemap

Use of the interface is documented at https://www.kernel.org/doc/Documentation/vm/pagemap.txt

Additional information about the page's translation is available using /proc/kpageflags, but that requires root access.

Thank  you very much. I am working on that will come back if there is any issue...
