Hi,
I am trying to memory-map I/O-physical memory to a user process which does a mmap call.(It is my small custom driver.) However, I am not able to find sufficient documentation on memory mapping physical memory to vm_object inside mmap_single.
I have implemented d_mmap and it works without any issues. But I don't want mmap to be called for every page two times. So, I am trying to explore mmap_single. Can someone direct me to some documentation?
Thanks.
