2021-04-29perf report: Add --skip-empty option to suppress 0 event statNamhyung Kim
To make the output more readable, I think it's better to remove 0's in the output. Also the dummy event has no event stats so it just wasts the space. Let's use the --skip-empty option to suppress it. $ perf report --stat --skip-empty Aggregated stats: TOTAL events: 16530 MMAP events: 226 COMM events: 1596 EXIT events: 2 THROTTLE events: 121 UNTHROTTLE events: 117 FORK events: 1595 SAMPLE events: 719 MMAP2 events: 12147 CGROUP events: 2 FINISHED_ROUND events: 2 THREAD_MAP events: 1 CPU_MAP events: 1 TIME_CONV events: 1 cycles stats: SAMPLE events: 719 Reviewed-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Namhyung Kim <namhyung@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20210427013717.1651674-5-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2021-04-29perf report: Show event sample counts in --stat outputNamhyung Kim
To make the output identical with perf report -D, it needs to show per-event sample counts along with the aggregated stat at the end.

2021-04-29perf hists: Split hists_stats from events_statsNamhyung Kim
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. This makes the output of event statistics in the perf report compact by skipping 0 events in each evsel/hists.

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’?

2021-04-29drm/i915/gvt: Prevent divided by zero when calculating refresh rateColin Xu
To get refresh rate as vblank timer period and keep the precision, the calculation of rate is multiplied by 1000. However old logic was using: rate = pixel clock / (h * v / 1000). When the h/v total is invalid, like all 0, h * v / 1000 will be rounded to 0, which leads to a divided by 0 fault. 0 H/V are already checked above. Instead of divide after divide, refine the calculation to divide after multiply: "pixel clock * 1000 / (h * v)" Guest driver should guarantee the correctness of the timing regs' value.

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.

During ufs system suspend, leaving rpm_dev_flush_recheck_work running or pending is risky because concurrency may happen between system suspend/resume and runtime resume routine.

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.

This means that it does further handling for the tcmu device. Skip that handling by replacing 'break' with 'return'.

Pull io_uring updates from Jens Axboe: - Support for multi-shot mode for POLL requests - More efficient reference counting. This is shamelessly stolen from the mm side. Even though referencing is mostly single/dual user, the 128 count was retained to keep the code the same. Maybe this should/could be made generic at some point. - Removal of the need to have a manager thread for each ring. The manager threads only job was checking and creating new io-threads as needed, instead we handle this from the queue path. - Allow SQPOLL without CAP_SYS_ADMIN or CAP_SYS_NICE. Since 5.12, this thread is "just" a regular application thread, so no need to restrict use of it anymore. - Cleanup of how internal async poll data lifetime is managed. - Fix for syzbot reported crash on SQPOLL cancelation. - Make buffer registration more like file registrations, which includes flexibility in avoiding full set unregistration and re-registration. - Fix for io-wq affinity setting. - Be a bit more defensive in task->pf_io_worker setup. - Various SQPOLL fixes. - Cleanup of SQPOLL creds handling. - Improvements to in-flight request tracking. - File registration cleanups. - Tons of cleanups and little fixes * tag 'for-5.13/io_uring-2021-04-27' of git://git.kernel.dk/linux-block: (156 commits) io_uring: maintain drain logic for multishot poll requests io_uring: Check current->io_uring in io_uring_cancel_sqpoll io_uring: fix NULL reg-buffer io_uring: simplify SQPOLL cancellations io_uring: fix work_exit sqpoll cancellations io_uring: Fix uninitialized variable up.resv io_uring: fix invalid error check after malloc io_uring: io_sq_thread() no longer needs to reset current->pf_io_worker kernel: always initialize task->pf_io_worker to NULL io_uring: update sq_thread_idle after ctx deleted io_uring: add full-fledged dynamic buffers support io_uring: implement fixed buffers registration similar to fixed files io_uring: prepare fixed rw for dynanic buffers io_uring: keep table of pointers to ubufs io_uring: add generic rsrc update with tags io_uring: add IORING_REGISTER_RSRC io_uring: enumerate dynamic resources io_uring: add generic path for rsrc update io_uring: preparation for rsrc tagging io_uring: decouple CQE filling from requests ...
