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. Maciej
