[GIT pull] perf updates for 4.17
Linus,
please pull the latest perf-urgent-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git
perf-urgent-for-linus
The perf update contains the following bits:
x86:
- Prevent setting freeze_on_smi on PerfMon V1 CPUs to avoid #GP
perf stat:
- Keep the '/' event modifier separator in fallback, for example when
fallbacking from 'cpu/cpu-cycles/' to user level only, where it should
become 'cpu/cpu-cycles/u' and not 'cpu/cpu-cycles/:u' (Jiri Olsa)
- Fix PMU events parsing rule, improving error reporting for
invalid events (Jiri Olsa)
- Disable write_backward and other event attributes for !group
events in a group, fixing, for instance this group:
'{cycles,msr/aperf/}:S'
that has leader sampling (:S) and where just the 'cycles',
the leader event, should have the write_backward attribute
set, in this case it all fails because the PMU where 'msr/aperf/'
lives doesn't accepts write_backward style sampling (Jiri Olsa)
- Only fall back group read for leader (Kan Liang)
- Fix core PMU alias list for x86 platform (Kan Liang)
- Print out hint for mixed PMU group error (Kan Liang)
- Fix duplicate PMU name for interval print (Kan Liang)
Core:
- Set main kernel end address properly when reading kernel and
module maps (Namhyung Kim)
perf mem:
- Fix incorrect entries and add missing man options (Sangwon Hong)
s/390:
- Remove s390 specific strcmp_cpuid_cmp function (Thomas Richter)
- Adapt 'perf test' case record+probe_libc_inet_pton.sh for s390
- Fix s390 undefined record__auxtrace_init() return value in
'perf record' (Thomas Richter)
Thanks,
tglx

Linus,
please pull the latest perf-urgent-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git
perf-urgent-for-linus
A rather large set of perf updates:
- 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
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 various initialization issues
- Prevent creating [ku]probes for not CAP_SYS_ADMIN users
- Fix a strncpy issue in uprobe tracing
Thanks,
tglx
