It outputs 'unknown' for all symbols parsing. This issue is root caused by the function elf__needs_adjust_symbols(), x86 perf tool uses one weak version, Arm64 (and powerpc) has rewritten their own version. elf__needs_adjust_symbols() decides if need to parse symbols with the relative offset address; but x86 building uses the weak function which misses to check for the elf type 'ET_DYN', so that it cannot parse symbols in Arm DSOs due to the wrong result from elf__needs_adjust_symbols(). The DSO parsing should not depend on any specific architecture perf building; e.g. x86 perf tool can parse Arm and Arm64 DSOs, vice versa. And confirmed by Naveen N. Rao that powerpc64 kernels are not being built as ET_DYN anymore and change to ET_EXEC. This patch removes the arch specific functions for Arm64 and powerpc and changes elf__needs_adjust_symbols() as a common function. In the common elf__needs_adjust_symbols(), it checks an extra condition 'ET_DYN' for elf header type. With this fixing, the Arm64 DSO can be parsed properly with x86's perf tool.

The annotation state is all tied to symbols, but there are either no symbols, or symbols are not covering all the code. We should support the annotation functionality even without symbols.

But with the current upstream, metric events names are not printed properly incase we try to run multiple metric groups with overlapping event. With current upstream version, incase of overlapping metric events issue is, we always start our comparision logic from start. So, the events which already matched with some metric group also take part in comparision logic. Because of that when we have overlapping events, we end up matching current metric group event with already matched one. For example, in skylake machine we have metric event CoreIPC and Instructions. Both of them need 'inst_retired.any' event value. As events in Instructions is subset of events in CoreIPC, they endup in pointing to same 'inst_retired.any' value. In skylake platform: command:# ./perf stat -M CoreIPC,Instructions -C 0 sleep 1 Performance counter stats for 'CPU(s) 0': 1,254,992,790 inst_retired.any # 1254992790.0 Instructions # 1.3 CoreIPC 977,172,805 cycles 1,254,992,756 inst_retired.any 1.000802596 seconds time elapsed command:# sudo ./perf stat -M UPI,IPC sleep 1 Performance counter stats for 'sleep 1': 948,650 uops_retired.retire_slots 866,182 inst_retired.any # 0.7 IPC 866,182 inst_retired.any 1,175,671 cpu_clk_unhalted.thread Patch fixes the issue by adding a new bool pointer 'evlist_used' to keep track of events which already matched with some group by setting it true. So, we skip all used events in list when we start comparision logic. Patch also make some changes in comparision logic, incase we get a match miss, we discard the whole match and start again with first event id in metric event. With this patch: In skylake platform: command:# ./perf stat -M CoreIPC,Instructions -C 0 sleep 1 Performance counter stats for 'CPU(s) 0': 3,348,415 inst_retired.any # 0.3 CoreIPC 11,779,026 cycles 3,348,381 inst_retired.any # 3348381.0 Instructions 1.001649056 seconds time elapsed command:# ./perf stat -M UPI,IPC sleep 1 Performance counter stats for 'sleep 1': 1,023,148 uops_retired.retire_slots # 1.1 UPI 924,976 inst_retired.any 924,976 inst_retired.any # 0.6 IPC 1,489,414 cpu_clk_unhalted.thread 1.003064672 seconds time elapsed Signed-off-by: Kajol Jain Acked-by: Jiri Olsa Cc: Alexander Shishkin Cc: Andi Kleen Cc: Anju T Sudhakar Cc: Jin Yao Cc: Kan Liang Cc: Madhavan Srinivasan Cc: Peter Zijlstra Cc: Ravi Bangoria Link: http://lore.kernel.org/lkml/20200221101121.28920-1-kjain@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/metricgroup.c | 49 ++++++++++++++++++++++++++----------------- 1 file changed, 30 insertions(+), 19 deletions(-) (limited to 'tools') diff --git a/tools/perf/util/metricgroup.c b/tools/perf/util/metricgroup.c index c3a8c701609a..926449a7cdbf 100644 --- a/tools/perf/util/metricgroup.c +++ b/tools/perf/util/metricgroup.c @@ -95,13 +95,16 @@ struct egroup { static struct evsel *find_evsel_group(struct evlist *perf_evlist, const char **ids, int idnum, - struct evsel **metric_events) + struct evsel **metric_events, + bool *evlist_used) { struct evsel *ev; - int i = 0; + int i = 0, j = 0; bool leader_found; evlist__for_each_entry (perf_evlist, ev) { + if (evlist_used[j++]) + continue; if (!strcmp(ev->name, ids[i])) { if (!metric_events[i]) metric_events[i] = ev; @@ -109,22 +112,17 @@ static struct evsel *find_evsel_group(struct evlist *perf_evlist, if (i == idnum) break; } else { - if (i + 1 == idnum) { - /* Discard the whole match and start again */ - i = 0; - memset(metric_events, 0, - sizeof(struct evsel *) * idnum); - continue; - } - - if (!strcmp(ev->name, ids[i])) - metric_events[i] = ev; - else { - /* Discard the whole match and start again */ - i = 0; - memset(metric_events, 0, - sizeof(struct evsel *) * idnum); - continue; + /* Discard the whole match and start again */ + i = 0; + memset(metric_events, 0, + sizeof(struct evsel *) * idnum); + + if (!strcmp(ev->name, ids[i])) { + if (!metric_events[i]) + metric_events[i] = ev; + i++; + if (i == idnum) + break; } } } @@ -146,7 +144,10 @@ static struct evsel *find_evsel_group(struct evlist *perf_evlist, !strcmp(ev->name, metric_events[i]->name)) { ev->metric_leader = metric_events[i]; } + j++; } + ev = metric_events[i]; + evlist_used[ev->idx] = true; } return metric_events[0]; @@ -162,6 +163,13 @@ static int metricgroup__setup_events(struct list_head *groups, int ret = 0; struct egroup *eg; struct evsel *evsel; + bool *evlist_used; + + evlist_used = calloc(perf_evlist->core.nr_entries, sizeof(bool)); + if (!evlist_used) { + ret = -ENOMEM; + return ret; + } list_for_each_entry (eg, groups, nd) { struct evsel **metric_events; @@ -172,7 +180,7 @@ static int metricgroup__setup_events(struct list_head *groups, break; } evsel = find_evsel_group(perf_evlist, eg->ids, eg->idnum, - metric_events); + metric_events, evlist_used); if (!evsel) { pr_debug("Cannot resolve %s: %s\n", eg->metric_name, eg->metric_expr); @@ -196,6 +204,9 @@ static int metricgroup__setup_events(struct list_head *groups, expr->metric_events = metric_events; list_add(&expr->nd, &me->head); } + + free(evlist_used); + return ret; } -- cgit v1.2.3 From c5f18e9e94bad244115dc5e47f27bd061ecc5552 Mon Sep 17 00:00:00 2001 From: Vijay Thakkar Date: Wed, 18 Mar 2020 15:00:00 -0400 Subject: perf vendor events amd: Restrict model detection for zen1 based processors MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch changes the previous blanket detection of AMD Family 17h processors to be more specific to Zen1 core based products only by replacing model detection regex pattern [[:xdigit:]]+ with ([12][0-9A-F]|[0-9A-F]), restricting to models 0 though 2f only. This change is required to allow for the addition of separate PMU events for Zen2 core based models in the following patches as those belong to family 17h but have different PMCs. Current PMU events directory has also been renamed to "amdzen1" from "amdfam17h" to reflect this specificity. Note that although this change does not break PMU counters for existing zen1 based systems, it does disable the current set of counters for zen2 based systems. Counters for zen2 have been added in the following patches in this patchset.

The model number regex has been set to detect all the models under family 17 that do not match those of Zen1, as the range is larger for zen2. Zen2 adds some additional counters that are not present in Zen1 and events for them have been added in this patch. Some counters have also been removed for Zen2 thatwere previously present in Zen1 and have been confirmed to always sample zero on zen2. These added/removed counters have been omitted for brevity but can be found here: https://gist.github.com/thakkarV/5b12ca5fd7488eb2c42e451e40bdd5f3 Note that PPR for Zen2 [1] does not include some counters that were documented in the PPR for Zen1 based processors [2]. After having tested these counters, some of them that still work for zen2 systems have been preserved in the events for zen2. The counters that are omitted in [1] but are still measurable and non-zero on zen2 (tested on a Ryzen 3900X system) are the following: PMC 0x000 fpu_pipe_assignment.{total|total0|total1|total2|total3}

Note that some events, such as FPU pipe assignment are missing in [1], and therefore [3] is included for full coverage of events. PMCs added: fpu_pipe_assignment.dual{0|1|2|3} fpu_pipe_assignment.total{0|1|2|3} ls_mab_alloc.dc_prefetcher ls_mab_alloc.stores ls_mab_alloc.loads bp_dyn_ind_pred bp_de_redirect PMC removed: ex_ret_cond_misp Cumulative counts, fpu_pipe_assignment.total and fpu_pipe_assignment.dual, existed in v1, but did expose port-level counters. ex_ret_cond_misp has been removed as it has been removed from the latest versions of the PPR, and when tested, always seems to sample zero as tested on a Ryzen 3400G system.

These test events can be used for testing generation of pmu-event tables and alias creation for any arch. When running the pmu-events test case, these test events will be used as the platform-agnostic events, so aliases can be created per-PMU and validated against known expected values. To support the test events, add a "testcpu" entry in pmu_events_map[]. The pmu-events test will be able to lookup the events map for "testcpu", to verify the generated tables against expected values. The resultant generated pmu-events.c will now look like the following: struct pmu_event pme_ampere_emag[] = { { .name = "ldrex_spec", .event = "event=0x6c", .desc = "Exclusive operation spe...", .topic = "intrinsic", .long_desc = "Exclusive operation ...", }, ... }; struct pmu_event pme_test_cpu[] = { { .name = "uncore_hisi_ddrc.flux_wcmd", .event = "event=0x2", .desc = "DDRC write commands.

So currently we verify that the generated pmu-events.c is as expected for some test events. Now test that we generate aliases as expected for those events during normal operation. For that, we cycle through each HW PMU in the system, and use the test events to create aliases, and verify those against known, expected values. For core PMUs, we should create an alias for every event in test_cpu_events[]. However, for uncore PMUs, they need to be matched by the pmu_event.pmu member, so use test_uncore_events[]; so check the match beforehand with pmu_uncore_alias_match().

Dso from buildid header does not have dso_id detail. And dso from MMAP2 samples does not have buildid information. If detail of the same dso is present at both the places, filename is common. Previously, __dsos__findnew_link_by_longname_id() used to compare only long or short names, but Commit 0e3149f86b99 ("perf dso: Move dso_id from 'struct map' to 'struct dso'") also added a dso_id comparison. Because of that, now perf is creating two different dso objects of the same file, one from buildid header (with dso_id but without buildid) and second from MMAP2 sample (with buildid but without dso_id). This is causing issues with archive, buildid-list etc subcommands. Fix this by comparing dso_id only when it's present. And incase dso is present in 'dsos' list without dso_id, inject dso_id detail as well. Before: $ sudo ./perf buildid-list -H 0000000000000000000000000000000000000000 /usr/bin/ls 0000000000000000000000000000000000000000 /usr/lib64/ld-2.30.so 0000000000000000000000000000000000000000 /usr/lib64/libc-2.30.so $ ./perf archive perf archive: no build-ids found After: $ ./perf buildid-list -H b6b1291d0cead046ed0fa5734037fa87a579adee /usr/bin/ls 641f0c90cfa15779352f12c0ec3c7a2b2b6f41e8 /usr/lib64/ld-2.30.so 675ace3ca07a0b863df01f461a7b0984c65c8b37 /usr/lib64/libc-2.30.so $ ./perf archive Now please run: $ tar xvf perf.data.tar.bz2 -C ~/.debug wherever you need to run 'perf report' on.

Sep 17 00:00:00 2001 From: Hagen Paul Pfeifer Date: Tue, 4 Feb 2020 18:37:09 +0100 Subject: perf script: Introduce --deltatime option For some kind of analysis a deltatime output is more human friendly and reduce the cognitive load for further analysis. The following output demonstrate the new option "deltatime": calculate the time difference in relation to the previous event. $ perf script --deltatime test 2525 [001] 0.000000: sdt_libev:ev_add:
