HI, How do i map the virtual address returned by ioremap() call to user space? The device driver book says we can use remap_page_range on this address. But don't we need to pass a physical address as an argument rather than the address returned by ioremap? Any pointer on this? And one more thing, can we just derefernce the mapped address in the application space as normal *(Address + offset). Any inputs on this is greatly appreciated.
