Add a more compact display format for kern.tty_info_kstacks inspired by procstat -kk. Set it as a default one. # sysctl kern.tty_info_kstacks=1 kern.tty_info_kstacks: 0 -> 1 # sleep 2 ^T load: 0.17 cmd: sleep 623 [nanslp] 0.72r 0.00u 0.00s 0% 2124k #0 0xffffffff80c4443e at mi_switch+0xbe #1 0xffffffff80c98044 at sleepq_catch_signals+0x494 #2 0xffffffff80c982c2 at sleepq_timedwait_sig+0x12 #3 0xffffffff80c43af3 at _sleep+0x193 #4 0xffffffff80c50e31 at kern_clock_nanosleep+0x1a1 #5 0xffffffff80c5119b at sys_nanosleep+0x3b #6 0xffffffff810ffc69 at amd64_syscall+0x119 #7 0xffffffff810d5520 at fast_syscall_common+0x101 sleep: about 1 second(s) left out of the original 2 ^C # sysctl kern.tty_info_kstacks=2 kern.tty_info_kstacks: 1 -> 2 # sleep 2 ^T load: 0.24 cmd: sleep 625 [nanslp] 0.81r 0.00u 0.00s 0% 2124k mi_switch+0xbe sleepq_catch_signals+0x494 sleepq_timedwait_sig+0x12 sleep+0x193 kern_clock_nanosleep+0x1a1 sys_nanosleep+0x3b amd64_syscall+0x119 fast_syscall_common+0x101 sleep: about 1 second(s) left out of the original 2 ^C Suggested by: avg Reviewed by: mjg Relnotes: yes Sponsored by: Mysterious Code Ltd.
