Merge tag 'perf-urgent-for-mingo-4.14-20170912' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

2017-09-13T07:25:10+00:00

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

- Fix TUI progress bar when delta from new total from that of the
  previous update is greater than the progress "step" (screen width
  progress bar block))  (Jiri Olsa)

- Make tools/lib/api make DEBUG=1 build use -D_FORTIFY_SOURCE=2 not
  to cripple debuginfo, just like tools/perf/ does (Jiri Olsa)

- Avoid leaking the 'perf.data' file to workloads started from the
  'perf record' command line by using the O_CLOEXEC open flag (Jiri Olsa)

- Fix building when libunwind's 'unwind.h' file is present in the
  include path, clashing with tools/perf/util/unwind.h (Milian Wolff)

- Check per .perfconfig section entry flag, not just per section (Taeung Song)

- Support running perf binaries with a dash in their name, needed to
  run perf as an AppImage (Milian Wolff)

- Wait for the right child by using waitpid() when running workloads
  from 'perf stat', also to fix using perf as an AppImage (Milian Wolff)

tools include linux: Guard against redefinition of some macros

2017-09-12T15:33:39+00:00

When cross building to android r15c (and older versions) on Fedora 26
we notice these:

/opt/android-ndk-r15c/platforms/android-24/arch-arm/usr/include/sys/cdefs.h:332:0: note: this is the location of the previous definition

For __aligned, __packed and __noreturn, so guard those with ifdefs to
avoid drowning useful warnings in these.

Merge tag 'char-misc-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

2017-09-05T18:08:17+00:00

Pull char/misc driver updates from Greg KH:
 "Here is the big char/misc driver update for 4.14-rc1.

  Lots of different stuff in here, it's been an active development cycle
  for some reason. Highlights are:

   - updated binder driver, this brings binder up to date with what
     shipped in the Android O release, plus some more changes that
     happened since then that are in the Android development trees.

   - coresight updates and fixes

   - mux driver file renames to be a bit "nicer"

   - intel_th driver updates

   - normal set of hyper-v updates and changes

   - small fpga subsystem and driver updates

   - lots of const code changes all over the driver trees

   - extcon driver updates

   - fmc driver subsystem upadates

   - w1 subsystem minor reworks and new features and drivers added

   - spmi driver updates

  Plus a smattering of other minor driver updates and fixes.

  All of these have been in linux-next with no reported issues for a
  while"

perf: cs-etm: Fix ETMv4 CONFIGR entry in perf.data file

2017-08-28T15:35:43+00:00

The value passed into the perf.data file for the CONFIGR register in ETMv4
was incorrectly being set to the command line options/ETMv3 value.

Adds bit definitions and function to remap this value to the correct ETMv4
CONFIGR bit values for all selected options.

tools include: Adopt strstarts() from the kernel

2017-07-20T18:46:10+00:00

Replacing prefixcmp(), same purpose, inverted result, so standardize on
the kernel variant, to reduce silly differences among tools/ and the
kernel sources, making it easier for people to work in both codebases.

And then doing:

	if (strstarts(option, "no-"))

Looks clearer than doing:

	if (!prefixcmp(option, "no-"))

To figure out if option starts witn "no-".

Pull perf updates from Ingo Molnar:
 "Most of the changes are for tooling, the main changes in this cycle were:

   - Improve Intel-PT hardware tracing support, both on the kernel and
     on the tooling side: PTWRITE instruction support, power events for
     C-state tracing, etc. (Adrian Hunter)

   - Add support to measure SMI cost to the x86 architecture, with
     tooling support in 'perf stat' (Kan Liang)

   - Support function filtering in 'perf ftrace', plus related
     improvements (Namhyung Kim)

   - Allow adding and removing fields to the default 'perf script'
     columns, using + or - as field prefixes to do so (Andi Kleen)

   - Allow resolving the DSO name with 'perf script -F brstack{sym,off},dso'
     (Mark Santaniello)

   - Add perf tooling unwind support for PowerPC (Paolo Bonzini)

   - ... and various other improvements as well"
