Here's an updated patch to sys/amd64/amd64/db_trace.c (it's a diff against revision 1.81). It changes "register rbp" to be "register_t rbp" and fixes the extra "W" in TD_IS_SWAPPED. The kernel built fine after these changes. I'll test it out tomorrow.

I've gone ahead and applied that change in Perforce, and look forward to hearing back on the testing.

I think procstat(1) is getting a lot closer to commitable state for 8-CURRENT, but further feedback would be most welcome (including reports of success on non-i386 architectures, and possibly patches to fix them). For FreeBSD developers with P4 access, you can also check out

Thank you for this.  I think procstat(1) is going to be very useful.

If you can think of other process-inspection related things it could be doing, let me know. The one thing I currently have in mind that I haven't made progress on is dumping the kernel signal state for the process (i.e., what signals have handlers, etc), which may be useful when debugging signal problems for an application.
