Apparently, Bullseye are dropping support for FreeBSD.
We are looking for an alternative for kernel module run time analysis.
Mostly interested in code coverage (for now).
Any suggestions that work for you?
Have you looked into /dev/kcov. This is used by SYZKALLER for getting
coverage information from the kernel.
Thanks.
Is there a man page for /dev/kcov?
Best regards

That's part of Matt Macy's gcov project, right?. However, while it
works for the kernel itself, it doesn't work for modules.
In worst case, I can build my module into the kernel, right?
