How do you read directly from physical memory?

Question

In C or C++ (windows), how do you read RAM by giving a physical (not virtual) address? That means without going trough virtual memory system (mmu tables), and being specific

Answer 1

I guess its not possible to access the physical address directly. Not even with administrative privilege.

Every address accessed by the the application is virtual address which is translated to physical address by hardware MMU.

One way is to configure MMU for one to one mapping the virtual address to physical address. This is usually done in embedded systems with no OS or before loading the OS.

With windows loaded. I believe your requirement is not possible.
