2019-08-08perf db-export: Fix thread__exec_comm()Adrian Hunter1-1/+11
Threads synthesized from /proc have comms with a start time of zero, and not marked as "exec". Currently, there can be 2 such comms. The first is created by processing a synthesized fork event and is set to the parent's comm string, and the second by processing a synthesized comm event set to the thread's current comm string. In the absence of an "exec" comm, thread__exec_comm() picks the last (oldest) comm, which, in the case above, is the parent's comm string. For a main thread, that is very probably wrong. Use the second-to-last in that case. This affects only db-export because it is the only user of thread__exec_comm(). Example: $ sudo perf record -a -o pt-a-sleep-1 -e intel_pt//u -- sleep 1 $ sudo chown ahunter pt-a-sleep-1 Before: $ perf script -i pt-a-sleep-1 --itrace=bep -s tools/perf/scripts/python/export-to-sqlite.py pt-a-sleep-1.db branches calls $ sqlite3 -header -column pt-a-sleep-1.db 'select * from comm_threads_view' comm_id command thread_id pid tid ---------- ---------- ---------- ---------- ---------- 1 swapper 1 0 0 2 rcu_sched 2 10 10 3 kthreadd 3 78 78 5 sudo 4 15180 15180 5 sudo 5 15180 15182 7 kworker/4: 6 10335 10335 8 kthreadd 7 55 55 10 systemd 8 865 865 10 systemd 9 865 875 13 perf 10 15181 15181 15 sleep 10 15181 15181 16 kworker/3: 11 14179 14179 17 kthreadd 12 29376 29376 19 systemd 13 746 746 21 systemd 14 401 401 23 systemd 15 879 879 23 systemd 16 879 945 25 kthreadd 17 556 556 27 kworker/u1 18 14136 14136 28 kworker/u1 19 15021 15021 29 kthreadd 20 509 509 31 systemd 21 836 836 31 systemd 22 836 967 33 systemd 23 1148 1148 33 systemd 24 1148 1163 35 kworker/2: 25 17988 17988 36 kworker/0: 26 13478 13478 After: $ perf script -i pt-a-sleep-1 --itrace=bep -s tools/perf/scripts/python/export-to-sqlite.py pt-a-sleep-1b.db branches calls $ sqlite3 -header -column pt-a-sleep-1b.db 'select * from comm_threads_view' comm_id command thread_id pid tid ---------- ---------- ---------- ---------- ---------- 1 swapper 1 0 0 2 rcu_sched 2 10 10 3 kswapd0 3 78 78 4 perf 4 15180 15180 4 perf 5 15180 15182 6 kworker/4: 6 10335 10335 7 kcompactd0 7 55 55 8 accounts-d 8 865 865 8 accounts-d 9 865 875 10 perf 10 15181 15181 12 sleep 10 15181 15181 13 kworker/3: 11 14179 14179 14 kworker/1: 12 29376 29376 15 haveged 13 746 746 16 systemd-jo 14 401 401 17 NetworkMan 15 879 879 17 NetworkMan 16 879 945 19 irq/131-iw 17 556 556 20 kworker/u1 18 14136 14136 21 kworker/u1 19 15021 15021 22 kworker/u1 20 509 509 23 thermald 21 836 836 23 thermald 22 836 967 25 unity-sett 23 1148 1148 25 unity-sett 24 1148 1163 27 kworker/2: 25 17988 17988 28 kworker/0: 26 13478 13478 Signed-off-by: Adrian Hunter <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: [email protected] Fixes: 65de51f93ebf ("perf tools: Identify which comms are from exec") Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
2019-08-08perf annotate: Fix printing of unaugmented disassembled instructions from BPFArnaldo Carvalho de Melo1-1/+1
The code to disassemble BPF programs uses binutil's disassembling routines, and those use in turn fprintf to print to a memstream FILE, adding a newline at the end of each line, which ends up confusing the TUI routines called from: annotate_browser__write() annotate_line__write() annotate_browser__printf() ui_browser__vprintf() SLsmg_vprintf() The SLsmg_vprintf() function in the slang library gets confused with the terminating newline, so make the disasm_line__parse() function that parses the lines produced by the BPF specific disassembler (that uses binutil's libopcodes) and the lines produced by the objdump based disassembler used for everything else (and that doesn't adds this terminating newline) trim the end of the line in addition of the beginning. This way when disasm_line->ops.raw, i.e. for instructions without a special scnprintf() method, we'll not have that \n getting in the way of filling the screen right after the instruction with spaces to avoid leaving what was on the screen before and thus garbling the annotation screen, breaking scrolling, etc. Cc: Adrian Hunter <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Song Liu <[email protected]> Fixes: 6987561c9e86 ("perf annotate: Enable annotation of BPF programs") Link: https://lkml.kernel.org/n/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
