AFAIK, no kernel since kprobes was introduced has ever stood up to that test. perf probe lacks the wildcarding powers of systemtap, so one needs to resort to something like: # cat /proc/kallsyms | grep ' [tT] ' | while read addr type symbol; do perf probe $symbol done then wait for a few hours for that to finish. Then, or while the loop is still running, run # perf record -e 'probe:*' -aR sleep 1 to take a kernel down. - FChE -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
