pmem: A Utility for Accessing Physical Memory

This module provides User Space applications with read access ot their page tables. This module should not be installed with full permissions on a production system because of security and safety. A User Space application can use mmap() and ioctl() on the module's created character device to resolve what physical memory is associated with the application's virtual addresses. The module can also request specific pages only if that page is not being used and is on the kernel's list of free pages.

Note: This module hasn't been updated since early 2.4 kernels and isn't currently supported.
