How to compile and load the device driver

1. Make a device driver and test programs.

   % make clean
   % make
   

2. Make the device files. Major number is 70 as default. You can change the value for your Linux system.

   % su
   # make devices
   

3. Load the device driver in Linux kernel.

   # /sbin/insmod ppci.o
   

4. Make sure if it is successfully loaded.

   % dmesg
   

   If you can find, a message "PPCI has been installed.", it's OK.
