      perf scripts python: exported-sql-viewer.py: Fix error when shrinking / enlarging font · 4b208453

      Fix the following error if shrink / enlarge font is used with the help
      window.
      
        Traceback (most recent call last):
          File "tools/perf/scripts/python/exported-sql-viewer.py", line 2791, in ShrinkFont

        AttributeError: 'HelpWindow' object has no attribute 'view'
      
      Committer testing:
      
      Before, matches above output:

        $
      
      After:
      
      No more tracebacks, but the fonts don't get enlarged, which is kinda
      frustrating...

      perf scripts python: exported-sql-viewer.py: Move view creation · be6e7471
      Adrian Hunter authored
      As preparation for adding support for copying to clipboard, create view
      in TreeWindowBase instead of derived classes.
      
      Committer testing:
      
      Tested using an old .db used to test some older patches:
      
        $ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db
      
      Nothing breaks.

      perf tools x86: Add support for recording and printing XMM registers · ca138a7a
      Andi Kleen authored
      Icelake and later platforms support collecting XMM registers with PEBS
      event.
      
      Add support for 'perf script' to dump them, and support for the register
      parser in 'perf record -I=' ... to configure them.
      
      For now they are just printed in hex, we could potentially later add
      other formats too.

      perf tools: Speed up report for perf compiled with linwunwind · 382619c0
      Jiri Olsa authored
      When compiled with libunwind, perf does some preparatory work when
      processing side-band events. This is not needed when report actually
      don't unwind dwarf callchains, so it's disabled with
      dwarf_callchain_users bool.
      
      However we could move that check to higher level and shield more
      unwanted code for normal report processing, giving us following speed up
      on kernel build profile:
      
      Before:
      
        $ perf record make -j40
        ...
        $ ll ../../perf.data
        -rw-------. 1 jolsa jolsa 461783932 Apr 26 09:11 perf.data
        $ perf stat -e cycles:u,instructions:u perf report -i perf.data > out
      
         Performance counter stats for 'perf report -i perf.data':
      
          78,669,920,155      cycles:u
          99,076,431,951      instructions:u            #    1.26  insn per cycle
      
            55.382823668 seconds time elapsed
      
            27.512341000 seconds user
            27.712871000 seconds sys
      
      After:
      
        $ perf stat -e cycles:u,instructions:u perf report -i perf.data > out
      
         Performance counter stats for 'perf report -i perf.data':
      
          59,626,798,904      cycles:u
          88,583,575,849      instructions:u            #    1.49  insn per cycle
      
            21.296935559 seconds time elapsed
      
            20.010191000 seconds user
             1.202935000 seconds sys
      
      The speed is higher with profile having many side-band events,
      because these trigger libunwind preparatory code.
      
      This does not apply for perf compiled with libdw for dwarf unwind,
      only for build with libunwind.

      perf annotate: Remove hist__account_cycles() from callback · bdd1666b
      Jin Yao authored
      The hist__account_cycles() function is executed when the
      hist_iter__branch_callback() is called.
      
      But it looks it's not necessary.  In hist__account_cycles, it already
      walks on all branch entries.
      
      This patch moves the hist__account_cycles out of callback, now the data
      processing is much faster than before.
      
      Previous code has an issue that the ch[offset].num++ (in
      __symbol__account_cycles) is executed repeatedly since
      hist__account_cycles is called in each hist_iter__branch_callback, so
      the counting of ch[offset].num is not correct (too big).
      
      With this patch, the issue is fixed. And we don't need the code of
      "ch->reset >= ch->num / 2" to check if there are too many overlaps (in
      annotation__count_and_fill), otherwise some data would be hidden.
      
      Now, we can try, for example:
      
        perf record -b ...
        perf annotate or perf report -s symbol
      
      The before/after output should be no change.
      
       v3:
       ---
       Fix the crash in stdio mode.
       Like previous code, it needs the checking of ui__has_annotation()
       before hist__account_cycles()
      
       v2:
       ---
       1. Cover the similar perf report
       2. Remove the checking code "ch->reset >= ch->num / 2"

      perf/x86/intel: Fix INTEL_FLAGS_EVENT_CONSTRAINT* masking · 6b89d4c1
      Stephane Eranian authored
      On Intel Westmere, a cmdline as follows:
      
        $ perf record -e cpu/event=0xc4,umask=0x2,name=br_inst_retired.near_call/p ....
      
      was failing. Yet the event+ umask support PEBS.
      
      It turns out this is due to a bug in the the PEBS event constraint table for
      westmere. All forms of BR_INST_RETIRED.* support PEBS. Therefore the constraint
      mask should ignore the umask. The name of the macro INTEL_FLAGS_EVENT_CONSTRAINT()
      hint that this is the case but it was not. That macros was checking both the
      event code and event umask. Therefore, it was only matching on 0x00c4.
      There are code+umask macros, they all have *UEVENT*.
      
      This bug fixes the issue by checking only the event code in the mask.
      Both single and range version are modified.

      Pull mmiowb removal from Will Deacon:
       "Remove Mysterious Macro Intended to Obscure Weird Behaviours (mmiowb())
      
        Remove mmiowb() from the kernel memory barrier API and instead, for
        architectures that need it, hide the barrier inside spin_unlock() when
        MMIO has been performed inside the critical section.
      
        The only relatively recent changes have been addressing review
        comments on the documentation, which is in a much better shape thanks
        to the efforts of Ben and Ingo.
      
        I was initially planning to split this into two pull requests so that
        you could run the coccinelle script yourself, however it's been plain
        sailing in linux-next so I've just included the whole lot here to keep
        things simple"

      Pull x86 apic update from Ingo Molnar:
       "A single commit which unifies the unnecessarily diverged
        implementations of APIC timer initialization. As a result the
        max_delta parameter is now consistently taken into account"

       "This cycle had the following changes:
      
         - Timer tracing improvements (Anna-Maria Gleixner)
      
         - Continued tasklet reduction work: remove the hrtimer_tasklet
           (Thomas Gleixner)
      
         - Fix CPU hotplug remove race in the tick-broadcast mask handling
           code (Thomas Gleixner)
      
         - Force upper bound for setting CLOCK_REALTIME, to fix ABI
           inconsistencies with handling values that are close to the maximum
           supported and the vagueness of when uptime related wraparound might
           occur. Make the consistent maximum the year 2232 across all
           relevant ABIs and APIs. (Thomas Gleixner)
      
         - various cleanups and smaller fixes"
