2021-04-29perf tests: Add hybrid cases for 'Roundtrip evsel->name' testJin Yao
Since for one hw event, two hybrid events are created. For example, evsel->idx evsel__name(evsel) 0 cycles 1 cycles 2 instructions 3 instructions ... So for comparing the evsel name on hybrid, the evsel->idx needs to be divided by 2. # ./perf test 14 14: Roundtrip evsel->name : Ok Signed-off-by: Jin Yao <yao.jin@linux.intel.com> Reviewed-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Kan Liang <kan.liang@intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20210427070139.25256-20-yao.jin@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

perf-stat has supported some aggregation modes, such as --per-core, --per-socket and etc. While for hybrid event, it may only available on part of cpus.

2021-04-29perf stat: Add default hybrid eventsJin Yao
Previously if '-e' is not specified in perf stat, some software events and hardware events are added to evlist by default.

Since parse_events() has been supported to create two hardware events for one event on hybrid platform, so we just use parse_events(evlist, "cycles,instructions,branches,branch-misses") to create the default events and add them to evlist.

2021-04-29perf parse-events: Support event inside hybrid pmuJin Yao
On hybrid platform, user may want to enable events on one pmu. Following syntax are supported: cpu_core/<event>/ cpu_atom/<event>/ But the syntax doesn't work for cache event. Before: # perf stat -e cpu_core/LLC-loads/ -a -- sleep 1 event syntax error: 'cpu_core/LLC-loads/' \___ unknown term 'LLC-loads' for pmu 'cpu_core' Cache events are a bit complex. We can't create aliases for them. We use another solution. For example, if we use "cpu_core/LLC-loads/", in parse_events_add_pmu(), term->config is "LLC-loads". Then we create a new parser to scan "LLC-loads". The parse_events_add_cache() would be called during parsing. The parse_state->hybrid_pmu_name is used to identify the pmu where the event should be enabled on.

2021-04-29perf parse-events: Create two hybrid cache eventsJin Yao
For cache events, they have pre-defined configs. The kernel needs to know where the cache event comes from (e.g. from cpu_core pmu or from cpu_atom pmu). But the perf type PERF_TYPE_HW_CACHE can't carry pmu information. Now the type PERF_TYPE_HW_CACHE is extended to be PMU aware type. The PMU type ID is stored at attr.config[63:32]. When enabling a hybrid cache event without specified pmu, such as, 'perf stat -e LLC-loads -a', two events are created automatically.

But in order not to hardcode the "cpu_core" and "cpu_atom", and make the code in a generic way. So if the path "/sys/bus/event_source/devices/cpu_xxx/cpus" exists, the hybrid pmu exists.

2021-04-29perf jevents: Support unit value "cpu_core" and "cpu_atom"Jin Yao
For some Intel platforms, such as Alderlake, which is a hybrid platform and it consists of atom cpu and core cpu. Each cpu has dedicated event list. Part of events are available on core cpu, part of events are available on atom cpu. The kernel exports new cpu pmus: cpu_core and cpu_atom. The event in json is added with a new field "Unit" to indicate which pmu the event is available on. For example, one event in cache.json, { "BriefDescription": "Counts the number of load ops retired that", "CollectPEBSRecord": "2", "Counter": "0,1,2,3", "EventCode": "0xd2", "EventName": "MEM_LOAD_UOPS_RETIRED_MISC.MMIO", "PEBScounters": "0,1,2,3", "SampleAfterValue": "1000003", "UMask": "0x80", "Unit": "cpu_atom" }, The unit "cpu_atom" indicates this event is only available on "cpu_atom". In generated pmu-events.c, we can see: { .name = "mem_load_uops_retired_misc.mmio", .event = "period=1000003,umask=0x80,event=0xd2", .desc = "Counts the number of load ops retired that. Unit: cpu_atom ", .topic = "cache", .pmu = "cpu_atom", }, But if without this patch, the "uncore_" prefix is added before "cpu_atom", such as: .pmu = "uncore_cpu_atom" That would be a wrong pmu.

2021-04-29perf data: Add JSON exportNicholas Fraser
This adds a feature to export perf data to JSON. The resolved symbols are exported into the JSON so that external tools don't need to load the dsos themselves (or even have access to them at all.) This makes it easy to load and analyze perf data with standalone tools where direct perf or libbabeltrace integration is impractical. The exporter uses a minimal inline JSON encoding without any external dependencies. Currently it only outputs some headers and sample metadata but it's easily extensible. Use it like this: $ perf data convert --to-json out.json Committer notes: Fixup a __printf() bug that broke the build: util/data-convert-json.c:103:11: error: expected ‘)’ before numeric constant 103 | __(printf, 5, 6) | ^~ | ) util/data-convert-json.c: In function ‘output_sample_callchain_entry’: util/data-convert-json.c:124:2: error: implicit declaration of function ‘output_json_key_format’; did you mean ‘output_json_format’?

2021-04-28scsi: ufs: core: Narrow down fast path in system suspend pathCan Guo
If spm_lvl is set to 0 or 1, when system suspend kicks start and HBA is runtime active, system suspend may just bail without doing anything (the fast path), leaving other contexts still running, e.g., clock gating and clock scaling. When system resume kicks start, concurrency can happen between ufshcd_resume() and these contexts, leading to various stability issues. Add a check against HBA's runtime state and allowing fast path only if HBA is runtime suspended, otherwise let system suspend go ahead call ufshcd_suspend(). This will guarantee that these contexts are stopped by either runtime suspend or system suspend.

2021-04-28scsi: qla2xxx: Prevent PRLI in target modeAnastasia Kovaleva
In a case when the initiator in P2P mode by some circumstances does not send PRLI, the target, in a case when the target port's WWPN is less than initiator's, changes the discovery state in DSC_GNL. When gnl completes it sends PRLI to the initiator. Usually the initiator in P2P mode always sends PRLI.
