1. Add the source file somewhere below hw/.
2. Add a make rule to build the object file in Makefile.objs in the
same directory as the source file.
3. Compile QEMU and run with -device testpci.

Reading the source code is necessary to understand how things work.
You can find many examples of devices in the hw/ directory.  Using
git-log(1) can be helpful because it shows how new devices were
introduced.
