      perf: Do the big rename: Performance Counters -> Performance Events · cdd6c482
      Ingo Molnar 提交于
      Bye-bye Performance Counters, welcome Performance Events!
      
      In the past few months the perfcounters subsystem has grown out its
      initial role of counting hardware events, and has become (and is
      becoming) a much broader generic event enumeration, reporting, logging,
      monitoring, analysis facility.
      
      Naming its core object 'perf_counter' and naming the subsystem
      'perfcounters' has become more and more of a misnomer. With pending
      code like hw-breakpoints support the 'counter' name is less and
      less appropriate.
      
      All in one, we've decided to rename the subsystem to 'performance
      events' and to propagate this rename through all fields, variables
      and API names. (in an ABI compatible fashion)
      
      The word 'event' is also a bit shorter than 'counter' - which makes
      it slightly more convenient to write/handle as well.
      
      Thanks goes to Stephane Eranian who first observed this misnomer and
      suggested a rename.
      
      User-space tooling and ABI compatibility is not affected - this patch
      should be function-invariant. (Also, defconfigs were not touched to
      keep the size down.)
      
      This patch has been generated via the following script:
      
        FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')
      
        sed -i \
          -e 's/PERF_EVENT_/PERF_RECORD_/g' \
          -e 's/PERF_COUNTER/PERF_EVENT/g' \
          -e 's/perf_counter/perf_event/g' \
          -e 's/nb_counters/nb_events/g' \
          -e 's/swcounter/swevent/g' \
          -e 's/tpcounter_event/tp_event/g' \
          $FILES
      
        for N in $(find . -name perf_counter.[ch]); do
          M=$(echo $N | sed 's/perf_counter/perf_event/g')
          mv $N $M
        done
      
        FILES=$(find . -name perf_event.*)
      
        sed -i \
          -e 's/COUNTER_MASK/REG_MASK/g' \
          -e 's/COUNTER/EVENT/g' \
          -e 's/\<event\>/event_id/g' \
          -e 's/counter/event/g' \
          -e 's/Counter/Event/g' \
          $FILES
      
      ... to keep it as correct as possible. This script can also be
      used by anyone who has pending perfcounters patches - it converts
      a Linux kernel tree over to the new naming. We tried to time this
      change to the point in time where the amount of pending patches
      is the smallest: the end of the merge window.
      
      Namespace clashes were fixed up in a preparatory patch - and some
      stylistic fallout will be fixed up in a subsequent patch.
      
      ( NOTE: 'counters' are still the proper terminology when we deal
        with hardware registers - and these sed scripts are a bit
        over-eager in renaming them. I've undone some of that, but
        in case there's something left where 'counter' would be
        better than 'event' we can undo that on an individual basis
        instead of touching an otherwise nicely automated patch. )

      sh: Allow for kernel command line concatenation. · d724a9c9
      Pawel Moll 提交于
      So far kernel command line arguments could be passed in by a bootloader
      or defined as CONFIG_CMDLINE, which completely overwriting the first one.
      
      This change allows a developer to declare selected kernel parameters in
      a kernel configuration (eg. project-specific defconfig), retaining
      possibility of passing others by a bootloader.
      
      The obvious examples of the first type are MTD partition or
      bigphysarea-like region definitions, while "debug" option or network
      configuration should be given by a bootloader or a JTAG boot script.

      sh: Tidy up SH-4A boot_cpu_data.flags probing. · 0bf8513e
      Paul Mundt 提交于
      This tidies up the boot_cpu_data.flags probing on SH-4A. All of them have
      a few things in common, which we can blindly set, rather than having each
      subtype have to set the same flags. We can also make assumptions about
      cache ways and the validity of PTEA, so this also kills off CPU_HAS_PTEA
      as a config option. There was also a bug in the FPU probing, which is now
      tidied up.

      sh: clkfwk: Make clock-cpg usable for non-legacy platforms. · 36aa1e32
      Paul Mundt 提交于
      This adds a new SH_CLK_CPG for parts that have CPG support.
      SH_CLK_CPG_LEGACY is made to depend on this, and still needs to be set
      for platforms that want clock-cpg to register the legacy clocks. With
      this new config item in place, it is now possible to start layering more
      generic CPG code in place while other platforms transition off of the
      legacy clocks.
