You did not say whether you were inside or outside of the kernel when you wanted this information. I do not believe there is any standard way of getting the information from user-space. >From within the kernel, simply call virt_to_phys(addr) on a pointer 'addr'. The pointer must point to directly allocated or kmalloc'ed memory - no I/O mapping. Robert Love -- Kernelnewbies: Help each other learn about the Linux kernel.
