Am I correct? /dev/mem yes HOWEVER, there is a much nicer way to mmap a PCI device's resources, and that is sysfs. /sys/bus/pci/devices/0000:00:02.0/resource0 for example is the first resource of a PCI device on my system. No need to muck about with the dangerous /dev/mem; this one is at least well defined and portable across systems, including virtualization etc etc -- Kernelnewbies: Help each other learn about the Linux kernel.
