Hi all:
I got the IO memory emulation information from the http://user-mode-linux.sourceforge.net/iomem.html.
CONFIG_MMAPPER is turn on in the config.But I don't know how to
" assign a file to it by putting
on the command line. "
I started the uml as follow :
./linux ubd0=$HOME/$USER-$3\_COW,$3 ubd1=/dev/shm/swap_fs eth0=tuntap,,,192.168.0.
98 umid=$2\_$3 mem=64M dsp=/dev/dsp iomem=mmapper,/home/pwu/io_file
But I found the "iomem" only get the first one parameter,that  is "iomem=mmapper".The second parameter is lost.
what is the problem?Is the way that I set the iomem  right?
Thanks a lot!!!
Best regards.
