* perf tools: Remove debug.h from places where it is not neededArnaldo Carvalho de Melo2019-09-2016-17/+1
| | | | | | | | | | | | | | | | | Pruning a bit more the includes dependency tree. Building this thing on lots of containers takes time, we better reduce the time per build, each container is doing 6 builds when clang and clang-devel are available, and the plan is to do a 'make -C tools/perf build-test' that have many more. Also helps when doing normal development, as touching some random file will have a much reduced chance of triggering lots of rebuilds.

* perf build: Ignore intentional differences for the x86 insn decoderArnaldo Carvalho de Melo2019-08-311-4/+4
| | | | | | | | | | | | | | | | Since we need to build this in !x86, we need to explicitely use the x86 files, not things like asm/insn.h, so we intentionally differ from the master copy in the kernel sources, add -I diff directives to ignore just these differences when checking for drift.

* perf intel-pt: Use shared x86 insn decoderJosh Poimboeuf2019-08-3112-2627/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that there's a common version of the decoder for all tools, use it instead of the local copy. Also use perf's check-headers.sh script to diff the decoder files to make sure they remain in sync with the kernel version. Objtool has a similar check. Committer notes: Had to keep this all pointing explicitely to x86 headers/files, i.e. instead of asm/isnn.h we had to use ../include/asm/insn.h when the files were in differemt dirs, or just replace "<asm/foo.h>" with "foo.h". This way we continue to be able to process perf.data files with Intel PT traces in distros other than x86. Also fixed up the awk script paths to use $(srcdir)/tools/arch instead or relative directories so that we keep detached tarballs (make help | grep perf) working. For now the include lines in these headers are being ignored so as not to flag false reports of kernel/tools out of sync.

For example, on cascadelakex: root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_BANDWIDTH.TOTAL -a -- sleep 1 Performance counter stats for 'system wide': 1841092 unc_m_pmm_rpq_inserts 3680816 unc_m_pmm_wpq_inserts 1.001775055 seconds time elapsed root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_READ_LATENCY -a -- sleep 1 Performance counter stats for 'system wide': 860649746 unc_m_pmm_rpq_occupancy.all 1840557 unc_m_pmm_rpq_inserts 12790627455 unc_m_clockticks 1.001773348 seconds time elapsed No metrics 'UNC_M_PMM_BANDWIDTH.TOTAL' or 'UNC_M_PMM_READ_LATENCY' are reported. The issue is, the case of an alias expanding to mulitple events is not supported, typically the uncore events. (see comments in find_evsel_group()). For UNC_M_PMM_BANDWIDTH.TOTAL in above example, the expanded event group is '{unc_m_pmm_rpq_inserts,unc_m_pmm_wpq_inserts}:W', but the actual events passed to find_evsel_group are: unc_m_pmm_rpq_inserts unc_m_pmm_rpq_inserts unc_m_pmm_rpq_inserts unc_m_pmm_rpq_inserts unc_m_pmm_rpq_inserts unc_m_pmm_rpq_inserts unc_m_pmm_wpq_inserts unc_m_pmm_wpq_inserts unc_m_pmm_wpq_inserts unc_m_pmm_wpq_inserts unc_m_pmm_wpq_inserts unc_m_pmm_wpq_inserts For this multiple events case, it's not supported well. This patch introduces a new field 'metric_leader' in struct evsel. The first event is considered as a metric leader. For the rest of same events, they point to the first event via it's metric_leader field in struct evsel. This design is for adding the counting results of all same events to the first event in group (the metric_leader). With this patch, root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_BANDWIDTH.TOTAL -a -- sleep 1 Performance counter stats for 'system wide': 1842108 unc_m_pmm_rpq_inserts # 337.2 MB/sec UNC_M_PMM_BANDWIDTH.TOTAL 3682209 unc_m_pmm_wpq_inserts 1.001819706 seconds time elapsed root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_READ_LATENCY -a -- sleep 1 Performance counter stats for 'system wide': 861970685 unc_m_pmm_rpq_occupancy.all # 219.4 ns UNC_M_PMM_READ_LATENCY 1842772 unc_m_pmm_rpq_inserts 12790196356 unc_m_clockticks 1.001749103 seconds time elapsed Now we can see the correct metrics 'UNC_M_PMM_BANDWIDTH.TOTAL' and 'UNC_M_PMM_READ_LATENCY'.

* libtraceevent, perf tools: Changes in tep_print_event_* APIsTzvetomir Stoyanov2019-08-313-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Libtraceevent APIs for printing various trace events information are complicated, there are complex extra parameters. To control the way event information is printed, the user should call a set of functions in a specific sequence. These APIs are reimplemented to provide a more simple interface for printing event information. Removed APIs: tep_print_event_task() tep_print_event_time() tep_print_event_data() tep_event_info() tep_is_latency_format() tep_set_latency_format() tep_data_latency_format() tep_set_print_raw() A new API for printing event information is introduced: void tep_print_event(struct tep_handle *tep, struct trace_seq *s, struct tep_record *record, const char *fmt, ...); where "fmt" is a printf-like format string, followed by the event fields to be printed. Supported fields: TEP_PRINT_PID, "%d" - event PID TEP_PRINT_CPU, "%d" - event CPU TEP_PRINT_COMM, "%s" - event command string TEP_PRINT_NAME, "%s" - event name TEP_PRINT_LATENCY, "%s" - event latency TEP_PRINT_TIME, %d - event time stamp. A divisor and precision can be specified as part of this format string: "%precision.divisord". Example: "%3.1000d" - divide the time by 1000 and print the first 3 digits before the dot. Thus, the time stamp "123456000" will be printed as "123.456" TEP_PRINT_INFO, "%s" - event information. TEP_PRINT_INFO_RAW, "%s" - event information, in raw format. Example: tep_print_event(tep, s, record, "%16s-%-5d [%03d] %s %6.1000d %s %s", TEP_PRINT_COMM, TEP_PRINT_PID, TEP_PRINT_CPU, TEP_PRINT_LATENCY, TEP_PRINT_TIME, TEP_PRINT_NAME, TEP_PRINT_INFO); Output: ls-11314 [005] d.h. 185207.366383 function __wake_up Signed-off-by: Tzvetomir Stoyanov <tstoyanov@vmware.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: linux-trace-devel@vger.kernel.org Cc: Patrick McLean <chutzpah@gentoo.org> Link: http://lore.kernel.org/linux-trace-devel/20190801074959.22023-2-tz.stoyanov@gmail.com Link: http://lore.kernel.org/lkml/20190805204355.041132030@goodmis.org Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
