C++ has lots of issues which are not dealt with in the kernel.
-
Problems in linking.
-
Exception handling that needs to be turned off.
-
Memory management functions (like new and delete) which need to be implemented.
-
The kernel headers are not suitable for inclusion for a C++ compiler since they conflict with many C++ constructs ('class' for instance and more).
-
The kernel build system does not compile C++ correctly, or even at all.
-
separate the "top part" - the one that is getting called by Linux, like driver entry and exit points, interrupt functions, tasklets, whatever and handle them in a C layer. expose APIs for all of these facilities and other low level facilities (printk, hardware access and more) via C functions.
-
write a top part that only accesses these services by well controlled C functions which do not include the kernel headers and are C++ friendly. In the top part write a framework for device driver writing based on OO concepts (inherit from Device and implement the relevant methods).
-
Add ability to include header files directly in C++ code. Progress: have 'copy_headers' target in makefile which also applies patch but headers are still hard to work with... This is to be developed as a patch to the linux kernel (big project - watch out! may never happen...)
-
add a framework for writing char drivers
-
http://code.google.com/p/kernelcpp/ They do not have a buffer layer but instead do "extern C" before kernel headers. Try to see if this works for a big example. They have all kinds of other ideas about constructors for global object and so on.
