2021-04-29perf pmu: Save detected hybrid pmus to a global pmu listJin Yao5-1/+80
We identify the cpu_core pmu and cpu_atom pmu by explicitly checking following files: For cpu_core, checks: "/sys/bus/event_source/devices/cpu_core/cpus" For cpu_atom, checks: "/sys/bus/event_source/devices/cpu_atom/cpus" If the 'cpus' file exists and it has data, the pmu exists. 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. All the detected hybrid pmus are linked to a global list 'perf_pmu__hybrid_pmus' and then next we just need to iterate the list to get all hybrid pmu by using perf_pmu__for_each_hybrid_pmu.

2021-04-29perf pmu: Save pmu nameJin Yao2-1/+10
On hybrid platform, one event is available on one pmu (such as, available on cpu_core or on cpu_atom). This patch saves the pmu name to the pmu field of struct perf_pmu_alias. Then next we can know the pmu which the event can be enabled on.

2021-04-29perf jevents: Support unit value "cpu_core" and "cpu_atom"Jin Yao1-0/+2
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.

Each struct hists have events_stats but most of the fields were not used. It's to count number of samples and periods whether filtered or not. And other fields are used only by evlist. So it'd be better to split hists_stats and events_stats to reduce wasted memory in the struct hists.

2021-04-29perf data: Add JSON exportNicholas Fraser7-21/+418
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’?

This reverts commit 0c85a7e87465f2d4cbc768e245f4f45b2f299b05. The games with 'rm' are on (two separate instances) of a local variable, and make no difference. Quoting Aditya Pakki: "I was the author of the patch and it was the cause of the giant UMN revert. The patch is garbage and I was unaware of the steps involved in retracting it. I *believed* the maintainers would pull it, given it was already under Greg's list. The patch does not introduce any bugs but is pointless and is stupid. I accept my incompetence and for not requesting a revert earlier."

2021-04-24mm/filemap: fix mapping_seek_hole_data on THP & 32-bitHugh Dickins1-10/+11
No problem on 64-bit, or without huge pages, but xfstests generic/285 and other SEEK_HOLE/SEEK_DATA tests have regressed on huge tmpfs, and on 32-bit architectures, with the new mapping_seek_hole_data(). Several different bugs turned out to need fixing. u64 cast to stop losing bits when converting unsigned long to loff_t (and let's use shifts throughout, rather than mixed with * and /). Use round_up() when advancing pos, to stop assuming that pos was already THP-aligned when advancing it by THP-size. (This use of round_up() assumes that any THP has THP-aligned index: true at present and true going forward, but could be recoded to avoid the assumption.) Use xas_set() when iterating away from a THP, so that xa_index stays in synch with start, instead of drifting away to return bogus offset. Check start against end to avoid wrapping 32-bit xa_index to 0 (and to handle these additional cases, seek_data or not, it's easier to break the loop than goto: so rearrange exit from the function).

No problem on 64-bit, or without huge pages, but xfstests generic/308 hung uninterruptibly on 32-bit huge tmpfs. Since commit 0cc3b0ec23ce ("Clarify (and fix) in 4.13 MAX_LFS_FILESIZE macros"), MAX_LFS_FILESIZE is only a PAGE_SIZE away from wrapping 32-bit xa_index to 0, so the new find_lock_entries() has to be extra careful when handling a THP.
