Well, what about just showing an example of kernel code in C++, which
you consider nice?
I don't have access to that code (which was closed source anyway).
But it executed C++ code within a few cycles of entering the reset
vector (no standard BIOS), including but not limited to: programming the
memory controller (430MX chipset), servicing interrupts, hardware
accelerated 2D graphics (C&T 65550), IDE driver, simple filesystem,
simple windowing GUI, network driver (Tulip) etc.
More recently I participated in writing a filesystem in C++. That's in
userspace, but many of the techniques used in writing kernel code are
necessary there (extreme robustness, can't assume infinite memory,
There are C++ embedded kernels in http://www.zipworld.com.au/~akpm/ and
http://ecos.sourceware.org/, but I haven't looked at them, so I can't
say whether I consider them nice or not.
