Hi, root@gw:~/RTBench-0.1/results #> sysctl debug.ktr debug.ktr.alq_enable: 1 debug.ktr.alq_file: /tmp/ktr.out debug.ktr.alq_depth: 32768 debug.ktr.alq_failed: 0 debug.ktr.alq_cnt: 0 debug.ktr.alq_max: 0 debug.ktr.clear: 0 debug.ktr.version: 2 debug.ktr.entries: 32768 debug.ktr.compile: 536870912 debug.ktr.mask: 536870912 debug.ktr.cpumask: -1 daffy@gw:~ %> ll /tmp/ktr.out -rw------- 1 root wheel 0B Jul 17 21:13 /tmp/ktr.out root@gw:~ #> ktrdump -ct index cpu timestamp trace ------ --- ---------------- ----- nothing... [FROM MY KERNCONF] options KTR options ALQ options KTR_ALQ options KTR_ENTRIES=32768 options KTR_COMPILE=KTR_SCHED options KTR_MASK=KTR_SCHED [EOF] While KTR_INTR works, it seems that KTR_SCHED does not or maybee there is a magic sause ?
