What If Our Driver Is Not Compiled?

• Some Drivers might come as part of our Kernel's sources, but still not be compiled in the distribution's default Kernel.
• We can see this by looking for the Driver in the Kernel source tree...
• ... Or by reading about its existence on the web, or in the Kernel source documentation (/usr/src/linux/Documentation).
• To compile this Driver, we will need to perform a full Kernel compilation and then compile the Driver.
• Usually, the second time around, we will not need to re-compile the entire Kernel - just the 2nd Driver.
