Hello, cxx_class is the C++ class name that will be created when ValuePredictorParams::create() is called (the return value of that function). Usually, it's exactly the same as the Python class name.
Again, http://learning.gem5.org/book/part2/ explains many of these details. If you think something is missing from the book, please open an issue on the book's github (https://github.com/powerjg/learning_gem5/issues).
