Although Linux does not (yet) support this binary format, the good news is that you can learn how to write kernel modules by implementing COM support for the Linux kernel.

Then, these objects are used to generate the modules and the Linux kernel image. Putting It All Together: Adding the Coin Driver. Now that you know more about kbuild system basics, let's consider a ...

Modules are stilluseful when testing a new driver. You don’t need to build a new kernelimage every time you find and fix a problem in your driver code. Justload it as a module and try it. Keep in mind ...
