* perf evlist: Rename for_each() macros to for_each_entry()Arnaldo Carvalho de Melo2016-06-231-2/+2

* perf test: Ignore .scale and other special filesAndi Kleen2016-06-061-2/+2
| | | | | | | | | | | | | 'perf test' tries to parse all entries in /sys/devices/cpu/events/. Ignore the special entries like '.scale', which cannot be directly parsed as an event. This patch assumes all files containing a '.' are special and can be ignored.

* perf tools: Enable config and setting names for legacy cache eventsWang Nan2016-02-191-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows setting config terms for legacy cache events.

* perf tools: Enable config raw and numeric eventsWang Nan2016-02-191-0/+40

For example: # perf stat -e cycles/name=cyc/ ls ... 1821108 cyc ... # perf stat -e r6530160/name=event/ ls ... 1103195 event ... # perf record -e cycles -e 4:0x6530160/name=evtx,call-graph=fp/ -a sleep 1 ... # perf report --stdio ... # Samples: 124 of event 'cycles' 46.61% 0.00% swapper [kernel.vmlinux] [k] cpu_startup_entry 41.26% 0.00% swapper [kernel.vmlinux] [k] start_secondary ... # Samples: 91 of event 'evtx' ... 93.76% 0.00% swapper [kernel.vmlinux] [k] cpu_startup_entry | ---cpu_startup_entry | |--66.63%--call_cpuidle | cpuidle_enter | | ... 3 test cases are introduced to test config terms for symbol, raw and numeric events. Committer note: Further testing shows that we can retrieve the event name using 'perf evlist -v' and looking at the 'config' perf_event_attr field, i.e.: # perf record -e cycles -e 4:0x6530160/name=evtx,call-graph=fp/ -a sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 1.724 MB perf.data (2076 samples) ] # perf evlist cycles evtx # perf evlist -v cycles: size: 112, { sample_period, sample_freq }: 4000, sample_type: IP|TID|TIME|CPU|PERIOD|IDENTIFIER, read_format: ID, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1, task: 1, sample_id_all: 1, exclude_guest: 1, mmap2: 1, comm_exec: 1 evtx: type: 4, size: 112, config: 0x6530160, { sample_period, sample_freq }: 4000, sample_type: IP|TID|TIME|CALLCHAIN|CPU|PERIOD|IDENTIFIER, read_format: ID, disabled: 1, inherit: 1, freq: 1, sample_id_all: 1, exclude_guest: 1 # Signed-off-by: Wang Nan <wangnan0@huawei.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexei Starovoitov <ast@kernel.org> Cc: Brendan Gregg <brendan.d.gregg@gmail.com> Cc: Cody P Schafer <dev@codyps.com> Cc: He Kuang <hekuang@huawei.com> Cc: Jeremie Galarneau <jeremie.galarneau@efficios.com> Cc: Kirill Smelkov <kirr@nexedi.com> Cc: Li Zefan <lizefan@huawei.com> Cc: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Zefan Li <lizefan@huawei.com> Cc: pi3orama@163.com Link: http://lkml.kernel.org/r/1455882283-79592-13-git-send-email-wangnan0@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

* perf tests: Pass the subtest index to each test routineArnaldo Carvalho de Melo2015-11-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Some tests have sub-tests we want to run, so allow passing this. Wang tried to avoid having to touch all tests, but then, having the test.func in an anonymous union makes the build fail on older compilers, like the one in RHEL6, where: test a = { .func = foo, }; fails. To fix it leave the func pointer in the main structure and pass the subtest index to all tests, end result function is the same, but we have just one function pointer, not two, with and without the subtest index as an argument.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently libtraceevent emits warning on unsupported event formats. However it'd be better to see them only -v option is given. To do that, it needs to override the warning() function which is used in the libtracevent. Thus add set_warning_routine() same as set_die_routine() and check the verbose flag in our warning routine.

* perf tools: Force period term to overload global settingsJiri Olsa2015-07-291-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the command line option settings beats the per event period settings: With no global settings, we get per-event configuration: $ perf record -e 'cpu/instructions,period=20000/' sleep 1 $ perf evlist -v ... { sample_period, sample_freq }: 20000 ... With 'c' option period setup, we get 'c' option value: $ perf record -e 'cpu/instructions,period=20000/' -c 1000 sleep 1 $ perf evlist -v ... { sample_period, sample_freq }: 1000 ... This patch makes the per-event settings overload the global 'c' option setup: $ perf record -e 'cpu/instructions,period=20000/' -c 1000 sleep 1 $ perf evlist -v ... { sample_period, sample_freq }: 20000 ... I think the making the per-event settings to overload any other config makes more sense than current state. However it breaks the current 'period' term handling, which might cause some noise.. so let's see ;-). Also fixing parse event tests with the new behaviour.

* perf tests: Switch from open to openatRiku Voipio2015-05-291-6/+6

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding support to return error information from parse_events function. Following struct will be populated by parse_events function on return: struct parse_events_error { int idx; char *str; char *help; }; where 'idx' is the position in the string where the parsing failed, 'str' contains dynamically allocated error string describing the error and 'help' is optional help string. The change contains reporting function, which currently does not display anything. The code changes to supply error data for specific event types are coming in next patches. However this is what the expected output is: $ sudo perf record -e 'sched:krava' ls event syntax error: 'sched:krava' \___ unknown tracepoint ... $ perf record -e 'cpu/even=0x1/' ls event syntax error: 'cpu/even=0x1/' \___ unknown term valid terms: pc,any,inv,edge,cmask,event,in_tx,ldlat,umask,in_tx_cp,offcore_rsp,config,config1,config2,name,period,branch_type ... $ perf record -e cycles,cache-mises ls event syntax error: '..es,cache-mises' \___ parser error ...

However, we can't add any arch specific tests inside #ifdefs, because it will create collision between the element number inside #ifdef and the next one outside.

For example, all the fs-related stuff goes to tools/lib/api/fs/ from which we get libapikfs.a (acme got almost the naming he wanted :-)) and we link it into the tools which need it - in this case perf and tools/vm/page-types. acme: "Looking at the implementation, I think some tools can even link directly to the .o files, avoiding the .a file altogether. But that is just an optimization/finer granularity tools/lib/ cherrypicking that toolers can make use of." Fixup documentation cleaning target while at it.
