Suppose from userland I want to access a chunk of physical ram directly..... I have a device that maps some ram at 0x40000000 through 0x40010000. I know I can talk to it directly through /dev/mem, but is there an easier way? (i.e. I'd like to be able to directly access that piece of ram, somehow) Can this be done? If so, what am I missing? (as a side note, would mmap'ing the appropriate section of /dev/mem even work?) Kevin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
