Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull more perf updates from Thomas Gleixner:
"A rather large set of perf updates:
Kernel:
- Fix various initialization issues
- Prevent creating [ku]probes for not CAP_SYS_ADMIN users
Tooling:
- Show only failing syscalls with 'perf trace --failure' (Arnaldo
Carvalho de Melo)
e.g: See what 'openat' syscalls are failing:
# perf trace --failure -e openat
762.323 ( 0.007 ms): VideoCapture/4566 openat(dfd: CWD, filename: /dev/video2) = -1 ENOENT No such file or directory
<SNIP N /dev/videoN open attempts... sigh, where is that improvised camera lid?!? >
790.228 ( 0.008 ms): VideoCapture/4566 openat(dfd: CWD, filename: /dev/video63) = -1 ENOENT No such file or directory
^C#
- Show information about the event (freq, nr_samples, total
period/nr_events) in the annotate --tui and --stdio2 'perf
annotate' output, similar to the first line in the 'perf report
--tui', but just for the samples for a the annotated symbol
(Arnaldo Carvalho de Melo)
- Introduce 'perf version --build-options' to show what features were
linked, aliased as well as a shorter 'perf -vv' (Jin Yao)
- Add a "dso_size" sort order (Kim Phillips)
- Remove redundant ')' in the tracepoint output in 'perf trace'
(Changbin Du)
- Synchronize x86's cpufeatures.h, no effect on toolss (Arnaldo
Carvalho de Melo)
- Show group details on the title line in the annotate browser and
'perf annotate --stdio2' output, so that the per-event columns can
have headers (Arnaldo Carvalho de Melo)
- Fixup vertical line separating metrics from instructions and
cleaning unused lines at the bottom, both in the annotate TUI
browser (Arnaldo Carvalho de Melo)
- Remove duplicated 'samples' in lost samples warning in
'perf report' (Arnaldo Carvalho de Melo)
- Synchronize i915_drm.h, silencing the perf build process,
automagically adding support for the new DRM_I915_QUERY ioctl
(Arnaldo Carvalho de Melo)
- Make auxtrace_queues__add_buffer() allocate struct buffer, from a
patchkit already applied (Adrian Hunter)
- Fix the --stdio2/TUI annotate output to include group details, be
it for a recorded '{a,b,f}' explicit event group or when forcing
group display using 'perf report --group' for a set of events not
recorded as a group (Arnaldo Carvalho de Melo)
- Fix display artifacts in the ui browser (base class for the
annotate and main report/top TUI browser) related to the extra
title lines work (Arnaldo Carvalho de Melo)
- perf auxtrace refactorings, leftovers from a previously partially
processed patchset (Adrian Hunter)
- Fix the builtin clang build (Sandipan Das, Arnaldo Carvalho de
Melo)
- Synchronize i915_drm.h, silencing a perf build warning and in the
process automagically adding support for a new ioctl command
(Arnaldo Carvalho de Melo)
- Fix a strncpy issue in uprobe tracing"
