      perf tools: Add attr->mmap2 support · 5c5e854b
      Stephane Eranian 提交于
      This patch adds support for the new PERF_RECORD_MMAP2 record type
      exposed by the kernel. This is an extended PERF_RECORD_MMAP record.
      
      It adds for each file-backed mapping the device major, minor number and
      the inode number and generation.
      
      This triplet uniquely identifies the source of a file-backed mapping. It
      can be used to detect identical virtual mappings between processes, for
      instance.
      
      The patch will prefer MMAP2 over MMAP.

      perf trace: Handle perf.data files with no tracepoints · ccf53eac
      Arnaldo Carvalho de Melo 提交于
      Before:
      
        perf trace -i perf.data
        Segmentation fault (core dumped)
        #
      
      After:
      
       # perf trace -i perf.data
       Data file does not have raw_syscalls:sys_enter events
       #
      
      When there are no tracepoints in a perf.data file the struct pevent
      that contains the list of tracepoints that will be used to lookup the
      tracepoint id by name will not be populated, causing a NULL deref.
      
      And we don't need to do all that dance to look at pevents for an entry
      with a slighly different name to then lookup the tracepoint by its id on
      the evlist, just use the perf_evlist__find_tracepoint_by_name() routine,
      that will find the tracepoint, if present.

      perf session: Separate progress bar update when processing events · 526fd8d4
      Jiri Olsa 提交于
      Currently when processing events in the __perf_session__process_events
      function we update a progress bar based on the file_size. During the
      same processing we update the progress bar from within
      flush_sample_queue which is based on number of samples count.
      
      Having 2 different based updates is causing the progress bar to jump
      heavily back and forth giving not much usefull info.
      
      Fixing this by keeping only __perf_session__process_events based
      progress bar update. And turning on flush_sample_queue progress bar
      update only for final flushing.
      
      This reduces the number of time the progress bar update function is
      called and it significantly reduces the loading time for TUI, where the
      progress bar update takes quite a lot of time.

      perf tools: Fix symbol offset computation for some dsos · 0b8c25d9

      It seems to be maps with a non-0 start. Taking that into account the

      perf tools: Add mem access sampling core support · 98a3b32c
      Stephane Eranian 提交于
      This patch adds the sorting and histogram support
      functions to enable profiling of memory accesses.
      
      The following sorting orders are added:
       - symbol_daddr: data address symbol (or raw address)
       - dso_daddr: data address shared object
       - locked: access uses locked transaction
       - tlb : TLB access
       - mem : memory level of the access (L1, L2, L3, RAM, ...)
       - snoop: access snoop mode

      perf tools: Add support for weight v7 (modified) · 05484298
      Andi Kleen 提交于
      perf record has a new option -W that enables weightened sampling.
      
      Add sorting support in top/report for the average weight per sample and the
      total weight sum. This allows to both compare relative cost per event
      and the total cost over the measurement period.
      
      Add the necessary glue to perf report, record and the library.
      
      v2: Merge with new hist refactoring.
      v3: Fix manpage. Remove value check.
      Rename global_weight to weight and weight to local_weight.
      v4: Readd sort keys to manpage
      v5: Move weight to end
      v6: Move weight to template
      v7: Rename weight key.
      
      Original patch from Andi modified by Stephane Eranian <eranian@google.com>
      to include ONLY the weight supporting code and apply to pristine 3.8.0-rc4.
