2020-07-06perf report TUI: Remove needless 'dummy' event from menuArnaldo Carvalho de Melo
Fixing the common case of: perf record perf report And getting just the cycles events. We now have a 'dummy' event to get perf metadata events that take place while we synthesize metadata records for pre-existing processes by traversing procfs, so we always have this extra 'dummy' evsel, but we don't have to offer it as there will be no samples on it, remove this distraction.

The segmentation fault can be reproduced as following steps: 1) Executing perf report in tui. 2) Typing '/xxxxx' to filter the symbol to get nothing matched. 3) Pressing enter with no entry selected. Then it will report a segmentation fault. It is caused by the lack of check of browser->he_selection when accessing it's member res_samples in perf_evsel__hists_browse().

2020-07-03perf record: Fix duplicated sideband events with Intel PT system wide tracingAdrian Hunter
Commit 0a892c1c9472 ("perf record: Add dummy event during system wide synthesis") reveals an issue with Intel PT system wide tracing. Specifically that Intel PT already adds a dummy tracking event, and it is not the first event. Adding another dummy tracking event causes duplicated sideband events. Fix by checking for an existing dummy tracking event first. Example showing duplicated switch events: Before: # perf record -a -e intel_pt//u uname Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.895 MB perf.data ] # perf script --no-itrace --show-switch-events | head swapper 0 [007] 6390.516222: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 11/11 swapper 0 [007] 6390.516222: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 11/11 rcu_sched 11 [007] 6390.516223: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 0/0 rcu_sched 11 [007] 6390.516224: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 0/0 rcu_sched 11 [007] 6390.516227: PERF_RECORD_SWITCH_CPU_WIDE OUT next pid/tid: 0/0 rcu_sched 11 [007] 6390.516227: PERF_RECORD_SWITCH_CPU_WIDE OUT next pid/tid: 0/0 swapper 0 [007] 6390.516228: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 11/11 swapper 0 [007] 6390.516228: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 11/11 swapper 0 [002] 6390.516415: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 5556/5559 swapper 0 [002] 6390.516416: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 5556/5559 After: # perf record -a -e intel_pt//u uname Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.868 MB perf.data ] # perf script --no-itrace --show-switch-events | head swapper 0 [005] 6450.567013: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 7179/7181 perf 7181 [005] 6450.567014: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 0/0 perf 7181 [005] 6450.567028: PERF_RECORD_SWITCH_CPU_WIDE OUT next pid/tid: 0/0 swapper 0 [005] 6450.567029: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 7179/7181 swapper 0 [005] 6450.571699: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 11/11 rcu_sched 11 [005] 6450.571700: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 0/0 rcu_sched 11 [005] 6450.571702: PERF_RECORD_SWITCH_CPU_WIDE OUT next pid/tid: 0/0 swapper 0 [005] 6450.571703: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 11/11 swapper 0 [005] 6450.579703: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 11/11 rcu_sched 11 [005] 6450.579704: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 0/0 Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lore.kernel.org/lkml/20200629091955.17090-3-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2020-06-22perf pmu: Improve CPU core PMU HW event list orderingJohn Garry
For perf list, the CPU core PMU HW event ordering is such that not all events may will be listed adjacent - consider this example: $ tools/perf/perf list List of pre-defined events (to be used in -e): duration_time [Tool event] branch-instructions OR cpu/branch-instructions/ [Kernel PMU event] branch-misses OR cpu/branch-misses/ [Kernel PMU event] bus-cycles OR cpu/bus-cycles/ [Kernel PMU event] cache-misses OR cpu/cache-misses/ [Kernel PMU event] cache-references OR cpu/cache-references/ [Kernel PMU event] cpu-cycles OR cpu/cpu-cycles/ [Kernel PMU event] cstate_core/c3-residency/ [Kernel PMU event] cstate_core/c6-residency/ [Kernel PMU event] cstate_core/c7-residency/ [Kernel PMU event] cstate_pkg/c2-residency/ [Kernel PMU event] cstate_pkg/c3-residency/ [Kernel PMU event] cstate_pkg/c6-residency/ [Kernel PMU event] cstate_pkg/c7-residency/ [Kernel PMU event] cycles-ct OR cpu/cycles-ct/ [Kernel PMU event] cycles-t OR cpu/cycles-t/ [Kernel PMU event] el-abort OR cpu/el-abort/ [Kernel PMU event] el-capacity OR cpu/el-capacity/ [Kernel PMU event] Notice in the above example how the cstate_core PMU events are mixed in the middle of the CPU core events. For my arm64 platform, all the uncore events get mixed in, making the list very disorganised: page-faults OR faults [Software event] task-clock [Software event] duration_time [Tool event] L1-dcache-load-misses [Hardware cache event] L1-dcache-loads [Hardware cache event] L1-icache-load-misses [Hardware cache event] L1-icache-loads [Hardware cache event] branch-load-misses [Hardware cache event] branch-loads [Hardware cache event] dTLB-load-misses [Hardware cache event] dTLB-loads [Hardware cache event] iTLB-load-misses [Hardware cache event] iTLB-loads [Hardware cache event] br_mis_pred OR armv8_pmuv3_0/br_mis_pred/ [Kernel PMU event] br_mis_pred_retired OR armv8_pmuv3_0/br_mis_pred_retired/ [Kernel PMU event] br_pred OR armv8_pmuv3_0/br_pred/ [Kernel PMU event] br_retired OR armv8_pmuv3_0/br_retired/ [Kernel PMU event] br_return_retired OR armv8_pmuv3_0/br_return_retired/ [Kernel PMU event] bus_access OR armv8_pmuv3_0/bus_access/ [Kernel PMU event] bus_cycles OR armv8_pmuv3_0/bus_cycles/ [Kernel PMU event] cid_write_retired OR armv8_pmuv3_0/cid_write_retired/ [Kernel PMU event] cpu_cycles OR armv8_pmuv3_0/cpu_cycles/ [Kernel PMU event] dtlb_walk OR armv8_pmuv3_0/dtlb_walk/ [Kernel PMU event] exc_return OR armv8_pmuv3_0/exc_return/ [Kernel PMU event] exc_taken OR armv8_pmuv3_0/exc_taken/ [Kernel PMU event] hisi_sccl1_ddrc0/act_cmd/ [Kernel PMU event] hisi_sccl1_ddrc0/flux_rcmd/ [Kernel PMU event] hisi_sccl1_ddrc0/flux_rd/ [Kernel PMU event] hisi_sccl1_ddrc0/flux_wcmd/ [Kernel PMU event] hisi_sccl1_ddrc0/flux_wr/ [Kernel PMU event] hisi_sccl1_ddrc0/pre_cmd/ [Kernel PMU event] hisi_sccl1_ddrc0/rnk_chg/ [Kernel PMU event] ... hisi_sccl7_l3c21/wr_hit_cpipe/ [Kernel PMU event] hisi_sccl7_l3c21/wr_hit_spipe/ [Kernel PMU event] hisi_sccl7_l3c21/wr_spipe/ [Kernel PMU event] inst_retired OR armv8_pmuv3_0/inst_retired/ [Kernel PMU event] inst_spec OR armv8_pmuv3_0/inst_spec/ [Kernel PMU event] itlb_walk OR armv8_pmuv3_0/itlb_walk/ [Kernel PMU event] l1d_cache OR armv8_pmuv3_0/l1d_cache/ [Kernel PMU event] l1d_cache_refill OR armv8_pmuv3_0/l1d_cache_refill/ [Kernel PMU event] l1d_cache_wb OR armv8_pmuv3_0/l1d_cache_wb/ [Kernel PMU event] l1d_tlb OR armv8_pmuv3_0/l1d_tlb/ [Kernel PMU event] l1d_tlb_refill OR armv8_pmuv3_0/l1d_tlb_refill/ [Kernel PMU event] So the events are list alphabetically. However, CPU core event listing is special from commit dc098b35b56f ("perf list: List kernel supplied event aliases"), in that the alias and full event is shown (in that order). As such, the core events may become sparse. Improve this by grouping the CPU core events and ensure that they are listed first for kernel PMU events. For the first example, above, this now looks like: duration_time [Tool event] branch-instructions OR cpu/branch-instructions/ [Kernel PMU event] branch-misses OR cpu/branch-misses/ [Kernel PMU event] bus-cycles OR cpu/bus-cycles/ [Kernel PMU event] cache-misses OR cpu/cache-misses/ [Kernel PMU event] cache-references OR cpu/cache-references/ [Kernel PMU event] cpu-cycles OR cpu/cpu-cycles/ [Kernel PMU event] cycles-ct OR cpu/cycles-ct/ [Kernel PMU event] cycles-t OR cpu/cycles-t/ [Kernel PMU event] el-abort OR cpu/el-abort/ [Kernel PMU event] el-capacity OR cpu/el-capacity/ [Kernel PMU event] el-commit OR cpu/el-commit/ [Kernel PMU event] el-conflict OR cpu/el-conflict/ [Kernel PMU event] el-start OR cpu/el-start/ [Kernel PMU event] instructions OR cpu/instructions/ [Kernel PMU event] mem-loads OR cpu/mem-loads/ [Kernel PMU event] mem-stores OR cpu/mem-stores/ [Kernel PMU event] ref-cycles OR cpu/ref-cycles/ [Kernel PMU event] topdown-fetch-bubbles OR cpu/topdown-fetch-bubbles/ [Kernel PMU event] topdown-recovery-bubbles OR cpu/topdown-recovery-bubbles/ [Kernel PMU event] topdown-slots-issued OR cpu/topdown-slots-issued/ [Kernel PMU event] topdown-slots-retired OR cpu/topdown-slots-retired/ [Kernel PMU event] topdown-total-slots OR cpu/topdown-total-slots/ [Kernel PMU event] tx-abort OR cpu/tx-abort/ [Kernel PMU event] tx-capacity OR cpu/tx-capacity/ [Kernel PMU event] tx-commit OR cpu/tx-commit/ [Kernel PMU event] tx-conflict OR cpu/tx-conflict/ [Kernel PMU event] tx-start OR cpu/tx-start/ [Kernel PMU event] cstate_core/c3-residency/ [Kernel PMU event] cstate_core/c6-residency/ [Kernel PMU event] cstate_core/c7-residency/ [Kernel PMU event] cstate_pkg/c2-residency/ [Kernel PMU event] cstate_pkg/c3-residency/ [Kernel PMU event] cstate_pkg/c6-residency/ [Kernel PMU event] cstate_pkg/c7-residency/ [Kernel PMU event] Signed-off-by: John Garry <john.garry@huawei.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Will Deacon <will@kernel.org> Cc: linux-arm-kernel@lists.infradead.org Cc: linuxarm@huawei.com Link: http://lore.kernel.org/lkml/1592384514-119954-3-git-send-email-john.garry@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2020-06-22perf pmu: List kernel supplied event aliases for arm64John Garry
In commit dc098b35b56f ("perf list: List kernel supplied event aliases"), the aliases for events are supplied in addition to CPU event in perf list. This relies on the name of the core PMU being "cpu", which is not the case for arm64, so arm64 has always missed this. Use generic is_pmu_core() helper which takes account of arm64 to make this feature work for arm64 (and possibly other archs).

2020-06-22perf tests: Add another metric parsing testJiri Olsa
The test goes through all metrics compiled for arch within pmu events and try to parse them. This test is different from 'test_parsing' in that we go through all the events in the current arch, not just one defined for current CPU model. Using 'fake_pmu' to parse events which do not have PMUs defined in the system. Say there's bad change in ivybridge metrics file, like: - a/tools/perf/pmu-events/arch/x86/ivybridge/ivb-metrics.json + b/tools/perf/pmu-events/arch/x86/ivybridge/ivb-metrics.json @@ -8,7 +8,7 @@ - "MetricExpr": "IDQ_UOPS_NOT_DELIVERED.CORE / (4 * (( + "MetricExpr": "IDQ_UOPS_NOT_DELIVERED.CORE / / (4 * the test fails with (on my kabylake laptop): $ perf test 'Parsing of PMU event table metrics with fake PMUs' -v parsing 'idq_uops_not_delivered.core / / (4 * (( ( cpu_clk_unh... syntax error, line 1 expr__parse failed test child finished with -1 ...

2020-06-22perf parse: Provide a way to pass a fake_pmu to parse_events()Arnaldo Carvalho de Melo
This is an alternative patch to what Jiri sent that instead of changing all callers to parse_events() for allowing to pass a fake_pmu, provide another function specifically for that. From Jiri's patch: This way it's possible to parse events from PMUs which are not present in the system. It's available only for testing purposes coming in following changes, so all the current users set fake_pmu argument as false.
