      tools/power: turbostat: fix large c1% issue · c3ae331d
      Len Brown authored
      Under some conditions, c1% was displayed as very large number,
      much higher than 100%.
      c1% is not measured, it is derived as "that, which is left over"
      from other counters.  However, the other counters are not collected
      atomically, and so it is possible for c1% to be calaculagted as
      a small negative number -- displayed as very large positive.
      There was a check for mperf vs tsc for this already,
      but it needed to also include the other counters
      that are used to calculate c1.

      tools/power: turbostat v2 - re-write for efficiency · c98d5d94
      Len Brown authored
      Measuring large profoundly-idle configurations
      requires turbostat to be more lightweight.
      Otherwise, the operation of turbostat itself
      can interfere with the measurements.
      This re-write makes turbostat topology aware.
      Hardware is accessed in "topology order".
      Redundant hardware accesses are deleted.
      Redundant output is deleted.
      Also, output is buffered and
      local RDTSC use replaces remote MSR access for TSC.
      From a feature point of view, the output
      looks different since redundant figures are absent.
      Also, there are now -c and -p options -- to restrict
      output to the 1st thread in each core, and the 1st
      thread in each package, respectively.  This is helpful
      to reduce output on big systems, where more detail
      than the "-s" system summary is desired.
      Finally, periodic mode output is now on stdout, not stderr.
      Turbostat v2 is also slightly more robust in
      handling run-time CPU online/offline events,
      as it now checks the actual map of on-line cpus rather
      than just the total number of on-line cpus.

      tools/power turbostat: fix IVB support · 650a37f3
      Len Brown authored
      Initial IVB support went into turbostat in Linux-3.1:
      (tools turbostat: recognize and run properly on IVB)
      However, when running on IVB, turbostat would fail
      to report the new couters added with SNB, c7, pc2 and pc7.
      So in scenarios where these counters are non-zero on IVB,
      turbostat would report erroneous residencey results.
      In particular c7 time would be added to c1 time,
      since c1 time is calculated as "that which is left over".
      Also, turbostat reports MHz capabilities when passed
      the "-v" option, and it would incorrectly report 133MHz
      bclk instead of 100MHz bclk for IVB, which would inflate
      GHz reported with that option.
      This patch is a backport of a fix already included in turbostat v2.

      tools/power turbostat: fix un-intended affinity of forked program · d15cf7c1
      Len Brown authored
      Linux 3.4 included a modification to turbostat to
      lower cross-call overhead by using scheduler affinity:
      (tools turbostat: reduce measurement overhead due to IPIs)
      In the use-case where turbostat forks a child program,
      that change had the un-intended side-effect of binding
      the child to the last cpu in the system.
      This change removed the binding before forking the child.
      This is a back-port of a fix already included in turbostat v2.

      nls: fix (and rename) mac NLS table files and config options · 8b8c0daa
      Linus Torvalds authored
      The config options in the Kconfig file (with _CODEPAGE_ in the name)
      didn't match the config option name in the Makefile (no _CODEPAGE_).
      And both of them were of the hard-to-read MACXYZZY variety, which made
      them hard to parse for normal humans: MACROMAN easily reads as "macro
      man", not as "Mac Roman".
      So rename the options to be consistent, and be NLS_MAC_xyzzy.  Rename
      the files to be mac-xyzzy.c too, and drop the "nls" part entirely (it's
      already in the directory name).

      x86, x32, ptrace: Remove PTRACE_ARCH_PRCTL for x32 · bad1a753
      H.J. Lu authored
      When I added x32 ptrace to 3.4 kernel, I also include PTRACE_ARCH_PRCTL
      support for x32 GDB  For ARCH_GET_FS/GS, it takes a pointer to int64.  But
      at user level, ARCH_GET_FS/GS takes a pointer to int32.  So I have to add
      x32 ptrace to glibc to handle it with a temporary int64 passed to kernel and
      copy it back to GDB as int32.  Roland suggested that PTRACE_ARCH_PRCTL
      is obsolete and x32 GDB should use fs_base and gs_base fields of
      user_regs_struct instead.
      Accordingly, remove PTRACE_ARCH_PRCTL completely from the x32 code to
      avoid possible memory overrun when pointer to int32 is passed to
