2015-10-22perf ui tui: Register the error callbacks before initializing the widgetsArnaldo Carvalho de Melo1-4/+4
I.e. we want to tell the user about errors found during, for instance, the ui_browser initialization, so that a call to ui__warning() appears as a window waiting for a key to be pressed.

2015-10-22perf annotate: Fix 'annotate.use_offset' config variable usageNamhyung Kim1-1/+1
The annotate__configs should be sorted so that it can use bsearch(3). However commit 0c4a5bcea460 ("perf annotate: Display total number of samples with --show-total-period") added a new config item at the end. This resulted in the 'annotate.use_offset' config variable cannot be found and perf terminated like below: $ perf report bad config file line 6 in ~/.perfconfig Signed-off-by: Namhyung Kim <namhyung@kernel.org> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Martin Liška <mliska@suse.cz> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Taeung Song <treeze.taeung@gmail.com> Fixes: 0c4a5bcea460 ("perf annotate: Display total number of samples with --show-total-period") Link: http://lkml.kernel.org/r/1445396240-3428-1-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2015-10-22perf tools: Improve call graph documents and help messagesNamhyung Kim6-30/+62
The --call-graph option is complex so we should provide better guide for users. Also change help message to be consistent with config option names. Now perf top will show help like below: $ perf top --call-graph Error: option `call-graph' requires a value Usage: perf top [<options>] --call-graph <record_mode[,record_size],print_type,threshold[,print_limit],order,sort_key[,branch]> setup and enables call-graph (stack chain/backtrace): record_mode: call graph recording mode (fp|dwarf|lbr) record_size: if record_mode is 'dwarf', max size of stack recording (<bytes>) default: 8192 (bytes) print_type: call graph printing style (graph|flat|fractal|none) threshold: minimum call graph inclusion threshold (<percent>) print_limit: maximum number of call graph entry (<number>) order: call graph order (caller|callee) sort_key: call graph sort key (function|address) branch: include last branch info to call graph (branch) Default: fp,graph,0.5,caller,function Requested-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Namhyung Kim <namhyung@kernel.org> Acked-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Borislav Petkov <bp@suse.de> Cc: Brendan Gregg <brendan.d.gregg@gmail.com> Cc: Chandler Carruth <chandlerc@gmail.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Stephane Eranian <eranian@google.com> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1445524112-5201-2-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2015-10-22perf tools: Defaults to 'caller' callchain order only if --children is enabledNamhyung Kim5-1/+9
The caller callchain order is useful with --children option since it can show 'overview' style output, but other commands which don't use --children feature like 'perf script' or even 'perf report/top' without --children are better to keep callee order.

2015-10-22perf top: Support call-graph display options alsoNamhyung Kim4-10/+62
Currently 'perf top --call-graph' option is same as 'perf record'. But 'perf top' also need to receive display options in 'perf report'. To do that, change parse_callchain_report_opt() to allow record options too. Now perf top can receive display options like below: $ perf top --call-graph Error: option `call-graph' requires a value Usage: perf top [<options>] --call-graph <mode[,dump_size],output_type,min_percent[,print_limit],call_order[,branch]> setup and enables call-graph (stack chain/backtrace) recording: fp dwarf lbr, output_type (graph, flat, fractal, or none), min percent threshold, optional print limit, callchain order, key (function or address), add branches $ perf top --call-graph callee,graph,fp Signed-off-by: Namhyung Kim <namhyung@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Borislav Petkov <bp@suse.de> Cc: Brendan Gregg <brendan.d.gregg@gmail.com> Cc: Chandler Carruth <chandlerc@gmail.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Stephane Eranian <eranian@google.com> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1445495330-25416-2-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2015-10-22tools lib traceevent: Support %ps/%pSScott Wood1-2/+2
Commits such as 65dd297ac25565 ("xfs: %pF is only for function pointers") caused a regression because pretty_print() didn't support %ps/%pS. The current %pf/%pF implementation in pretty_print() is what %ps/%pS is supposed to do, so use the same code for %ps/%pS. Addressing the incorrect %pf/%pF implementation is beyond the scope of this patch.

2015-10-20perf cpu_map: Fix core dump caused by per-socket/core system-wide statKan Liang1-1/+1
Perf will core dump if --per-socket/core -a are applied for perf stat. The root cause is that cpu_map__build_map set refcnt of evlist's cpu_map to 1. It should set refcnt for the newly created cpu_map, not evlist's cpu_map. Here is the example: # perf stat -e cycles --per-socket -a sleep 1 Performance counter stats for 'system wide': S0 36 30,196,257 cycles S1 28 15,823,536 cycles 1.001126828 seconds time elapsed *** Error in `./perf': corrupted double-linked list: 0x00000000021f9090 *** ======= Backtrace: ========= /lib64/libc.so.6[0x3002e7bbe7] /lib64/libc.so.6[0x3002e7d2b5] ./perf(perf_evsel__delete+0x28)[0x485bdd] ./perf[0x4800e8] ./perf(perf_evlist__delete+0x5e)[0x482cd5] ./perf(cmd_stat+0xf25)[0x432328] ./perf[0x4768e0] ./perf[0x476ad6] ./perf[0x476b41] ./perf(main+0x1d0)[0x476db2] /lib64/libc.so.6(__libc_start_main+0xf5)[0x3002e21b45] ./perf[0x4202c5] Signed-off-by: Kan Liang <kan.liang@intel.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Andi Kleen <ak@linux.intel.com> Link: http://lkml.kernel.org/r/1444388363-35936-1-git-send-email-kan.liang@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
