Linux Driver Read Physical Memory at Ernest Barber blog

Linux Driver Read Physical Memory. learn how to use mmap, get_user_pages, and dma i/o operations to map device memory into user or kernel space. uio is a system that allows some devices to be controlled by user space applications, with minimal kernel support. to access real physical memory you should use phys_to_virt function. Like its windows counterpart, winpmem, this is. In case it is io memory (e.g. See how to use mmap for memory. to use /dev/mem to view and modify regular ram on kernel v4.9, you must fist: learn about the memory mapping mechanisms and structures in the linux kernel, such as struct page, struct vm_area_struct and struct mm_struct. learn how to use memory mapped io for device drivers on linux, with functions such as readb_relaxed() and writel_relaxed(). learn how mmap works in linux, from process address space and vma to memory mapping principle and flags.
