Linux Driver Mmap at Gordon Blair blog

Linux Driver Mmap. if your driver need to support mmap a memory offset, then obvious there is a issue. consequently, implementation of a character device driver means implementing the system calls specific to files: In this case, you can just pass. A driver that supports mmap (and, thus, that implements the mmap method) needs to help that process by completing the initialization of that vma. Interrupts are handled by reading from. device driver memory mapping¶ memory mapping is one of the most interesting features of a unix system. Whenever the program reads or writes in. a driver that implements the mmap method needs to fill a vma structure in the address space of the process mapping the device. just use mmap() to access registers or ram locations of your card.
