Hi, I'm trying DTrace syscall provider (systrace) patch provided by riz some years ago(*) to complete the work. (I'm already ack-ed the handover by him.)
(*) https://mail-index.netbsd.org/tech-kern/2013/06/24/msg015296.html I needed some tweaks to make it work with -current, but it works (on amd64) anyway. Noticeable changes from the riz's patch are - Move systrace_probe_func definition to sys/kern/kern_dtrace.c from sys/arch/amd64/amd64/trap.c to support architectures other than amd64 - Make it buildable for i386 and arm (some fixes to dtrace itself are already committed) A known todo is to support syscall emulations, although it can be done later. I think only native syscall support is still worthwhile to merge. Here is a patch: http://www.netbsd.org/~ozaki-r/systrace-full.diff Er...the patch is too big to look at because it includes mechanically generated *sysent.c and *systrace_args.c. So I prepare another patch that excludes them: http://www.netbsd.org/~ozaki-r/systrace.diff And here is a git branch. Please use it if you want to see the changes as individual commits: https://github.com/ozaki-r/netbsd-src/commits/dtrace-syscall-provider Regards, ozaki-r
