simple, I have preexisting C++ code which we are currently using in userland and wish to push down into the kernel.
It would be ideal to keep the source bases the same without a rewrite to C. Admitting of course the possibility of having to modify to be compatible with both use modes.
At present I am attempting to see what we can and cannot do in the kernel with C++
FWIW, Darwin (the underpinnings for Mac OS X) uses C++ for its device drivers. This is done by hewing to a model roughly that of "Embedded C++", compiling statically, and having a separate library that differs from libstdc++ in significant ways. Getting this to work well was non-trivial, but it does work (sadly :-}).
If you are trying to get user-mode code to work in the kernel, you are in for an enjoyable year...
You can check Apple's Darwin site for available doc (http://developer.apple.com/darwin). The code is available under Apple's open source license (APSL 2.0).
