Hi Domagoj, A couple of recent projects which may be of interest are kinst, a new kernel provider which enables tracing of arbitrary kernel instructions on amd64, and CTFv3, which removes a number of limits in the previous version which were biting people. A description of the former, along with some future project ideas, is here: https://www.freebsd.org/status/report-2022-07-2022-09/#_dtrace_instruction_level_dynamic_tracing
