Testing Drivers

To avoid data loss and other problems, you should take special care when testing a new device driver. This section discusses various testing strategies. For example, setting up a separate system that you control through a serial connection is the safest way to test a new driver. You can load test modules with various kernel variable settings to test performance under different kernel conditions. Should your system crash, you should be prepared to restore backup data, analyze any crash dumps, and rebuild the device directory.
