I need to allocate physically contiguous pages from user space and get back the physical address. How can I do so? I need it physically contiguous because I'm working in-conjunction with hardware that needs that. get_free_pages as I understood is Kernel function and returns virtual address

I assume you mean "Physically contiguous PAGE FRAMES." – user3344003 Jan 07 '16 at 15:50
