Hello, I would like to create a kernel module that will somehow allow userspace to gain access to a physical memory map for the running system. Ideally it would show which physical memory regions (Some physical memory equivalent of a VMA?? I assume??) are in use by which processes. It would also show how fragmented physical memory is. I know where to find information on the Linux VMM, so that is not what I am after. My question is: Has anyone done (or seen) anything like this? If there is already something like this in the kernel (or somewhere out there) I would love to see it. Also, does it make sense to make this a separate loadable module? Thanks in advance for your time. :) ------------------------------------ Example output: (This is sort of like what I want to do) [0x00000000 - 0x00000D80] Process #1 [0x00000D81 - 0x0000F000] Process #2 ..... [0xnnnnnnnn - 0x_end_mem] Unallocated. ------------------------------------------ -- Jason J. Herne <hernejj@xxxxxxxxxxxx> -- Kernelnewbies: Help each other learn about the Linux kernel.
