2015-10-02 Thread martin
Hello, I'm working with a kernel module that, through hardware events, gets a list of physical and linear memory addresses accessed by a program. I would like to convert these to the virtual addresses, as seen from the user space. I saw there's phys_to_virt(), but as I understood it's only
