Simple question about mmap() system call

Physical memory access from kld

Hello! I'm trying to add Intel 875P chipset support for ecc.ko module. Basically this module outputs whether chipset supports and utilizes ECC, how much memory does it have, and whether there were memory errors. Well, this chipset has a very confusing architecture. Instead of having all relevan
