      perf stat: Add feature to run and measure a command multiple times · 42202dd5
      Ingo Molnar 提交于
      Add the --repeat <n> feature to perf stat, which repeats a given
      command up to a 100 times, collects the stats and calculates an
      average and a stddev.
      
      For example, the following oneliner 'perf stat' command runs hackbench
      5 times and prints a tabulated result of all metrics, with averages
      and noise levels (in percentage) printed:
      
       aldebaran:~/linux/linux/tools/perf> ./perf stat --repeat 5 ~/hackbench 10
       Time: 0.117
       Time: 0.108
       Time: 0.089
       Time: 0.088
       Time: 0.100
      
       Performance counter stats for '/home/mingo/hackbench 10' (5 runs):
      
          1243.989586  task-clock-msecs     #     10.460 CPUs    ( +-   4.720% )

                  387  CPU-migrations       #      0.000 M/sec   ( +-   3.608% )

           3770941606  cycles               #   3031.329 M/sec   ( +-   4.621% )
           1566372416  instructions         #      0.415 IPC     ( +-   2.703% )
             16783421  cache-references     #     13.492 M/sec   ( +-   5.202% )
              7128590  cache-misses         #      5.730 M/sec   ( +-   7.420% )
      
          0.118924455  seconds time elapsed.
      
      The goal of this feature is to allow the reliance on these accurate
      statistics and to know how many times a command has to be repeated
      for the noise to go down to an acceptable level.
      
      (The -v option can be used to see a line printed out as each run progresses.)

      perf annotate: Print a sorted summary of annotated overhead lines · 971738f3
      Frederic Weisbecker 提交于
      It's can be very annoying to scroll down perf annotated output
      until we find relevant overhead.
      
      Using the -l option, you can now have a small summary sorted per
      overhead in the beginning of the output.
      
      Example:
      
      ./perf annotate -l -k ../../vmlinux -s __lock_acquire
      
      Sorted summary for file ../../vmlinux

      perf annotate: Print the filename:line for annotated colored lines · 301406b9
      Frederic Weisbecker 提交于
      When we have a colored line in perf annotate, ie a middle/high
      overhead one, it's sometimes useful to get the matching line
      and filename from the source file, especially this path prepares
      to another subsequent one which will print a sorted summary of
      midle/high overhead lines in the beginning of the output.
      
      Filename:Lines have the same color than the concerned ip lines.
      
      It can be slow because it relies on addr2line. We could also
      use objdump with -l but that implies we would have to bufferize
      objdump output and parse it to filter the relevant lines since
      we want to print a sorted summary in the beginning.

      PM: Add empty suspend/resume device irq functions · 5818a6e2
      Heiko Carstens 提交于
      git commit 0a0c5168 "PM: Introduce functions for suspending and resuming
      device interrupts" introduced some helper functions. However these
      functions are only available for architectures which support
      GENERIC_HARDIRQS.
      
      Other architectures will see this build error:
      
      drivers/built-in.o: In function `sysdev_suspend':
      (.text+0x15138): undefined reference to `check_wakeup_irqs'
      drivers/built-in.o: In function `device_power_up':

      drivers/built-in.o: In function `device_power_down':
      (.text+0x1cb92): undefined reference to `suspend_device_irqs'
      
      To fix this add some empty inline functions for !GENERIC_HARDIRQS.

      The *_nvs_* routines in swsusp.c make use of the io*map()

      Driver Core: Rework platform suspend/resume, print warning · 783ea7d4
      Magnus Damm 提交于
      This patch reworks the platform driver code for legacy
      suspend and resume to avoid installing callbacks in
      struct device_driver. A warning is also added telling
      users to update the platform driver to use dev_pm_ops.
      
      The functions platform_legacy_suspend()/resume() directly
      call suspend and resume callbacks in struct platform_driver
      instead of wrapping things in platform_drv_suspend()/resume().

      PM/Hibernate: Move memory shrinking to snapshot.c (rev. 2) · fe419535

      A future patch is going to modify the memory shrinking code so that
      it will make memory allocations to free memory instead of using an
      artificial memory shrinking mechanism for that.  For this purpose it
      is convenient to move swsusp_shrink_memory() from
      kernel/power/swsusp.c to kernel/power/snapshot.c, because the new
      memory-shrinking code is going to use things that are local to
      kernel/power/snapshot.c .

      PM core: rename suspend and resume functions · d1616302
      Alan Stern 提交于
      This patch (as1241) renames a bunch of functions in the PM core.
      Rather than go through a boring list of name changes, suffice it to
      say that in the end we have a bunch of pairs of functions:
      
      	device_resume_noirq	dpm_resume_noirq
      	device_resume		dpm_resume
      	device_complete		dpm_complete
      	device_suspend_noirq	dpm_suspend_noirq
      	device_suspend		dpm_suspend
      	device_prepare		dpm_prepare
      
      in which device_X does the X operation on a single device and dpm_X
      invokes device_X for all devices in the dpm_list.
      
      In addition, the old dpm_power_up and device_resume_noirq have been
      combined into a single function (dpm_resume_noirq).
      
      Lastly, dpm_suspend_start and dpm_resume_end are the renamed versions
      of the former top-level device_suspend and device_resume routines.

      Rename the functions performing "_noirq" dev_pm_ops
      operations from device_power_down() and device_power_up()
      to device_suspend_noirq() and device_resume_noirq().
      
      The new function names are chosen to show that the functions
      are responsible for calling the _noirq() versions to finalize
      the suspend/resume operation. The current function names do
      not perform power down/up anymore so the names may be misleading.
      
      Global function renames:
      - device_power_down() -> device_suspend_noirq()
      - device_power_up() -> device_resume_noirq()
      
      Static function renames:
