Well done! -- something I have meant to do for years, but never come to.
Out of curiousity -- does your kernel side support MIPS architecture style
watchpoints only or does it work with the R4000-style watch registers as
well? I recall having a discussion with Daniel about how to support both
in a reasonably abstract way long ago. Either way thanks a lot, and I
have an R4k machine handy, so I can see if I find some time to give it a
shot.
