perf tools: Update quipper information (2018-03-08 11:30:54 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Support to display the IPC/Cycle in 'annotate' TUI, for systems
where this info can be obtained, like Intel's >= Skylake (Jin Yao)
- Support wildcards on PMU name in dynamic PMU events (Agustin Vega-Frias)
- Display pmu name when printing unmerged events in stat (Agustin Vega-Frias)
- Auto-merge PMU events created by prefix or glob match (Agustin Vega-Frias)
- Fix s390 'call' operations target function annotation (Thomas Richter)
- Handle s390 PC relative load and store instruction in the augmented
'annotate', code, used so far in the TUI modes of 'perf report' and
'perf annotate' (Thomas Richter)
- Provide libtraceevent with a kernel symbol resolver, so that
symbols in tracepoint fields can be resolved when showing them in
tools such as 'perf report' (Wang YanQing)
- Refactor the cgroups code to look more like other code in tools/perf,
using cgroup__{put,get} for refcount operations instead of its
open-coded equivalent, breaking larger functions, etc (Arnaldo Carvalho de Melo)
- Implement support for the -G/--cgroup target in 'perf trace', allowing
strace like tracing (plus other events, backtraces, etc) for cgroups
(Arnaldo Carvalho de Melo)
- Update thread shortname in 'perf sched map' when the thread's COMM
changes (Changbin Du)
- refcount 'struct mem_info', for better sharing it over several
users, avoid duplicating structs and fixing crashes related to
use after free (Jiri Olsa)
- Display perf.data version, offsets in 'perf report --header' (Jiri Olsa)
- Record the machine's memory topology information in a perf.data
feature section, to be used by tools such as 'perf c2c' (Jiri Olsa)
- Fix output of forced groups in the header for 'perf report' --stdio
and --tui (Jiri Olsa)
- Better support llvm, clang, cxx make tests in the build process (Jiri Olsa)
- Streamline the 'struct perf_mmap' methods, storing some info in the
struct instead of passing it via various methods, shortening its
signatures (Kan Liang)
- Update the quipper perf.data parser library site information (Stephane Eranian)
- Correct perf's man pages title markers for asciidoctor (Takashi Iwai)
- Intel PT fixes and refactorings paving the way for implementing
support for AUX area sampling (Adrian Hunter)

Test results:
The first ones are container (docker) based builds of tools/perf with and
without libelf support. Where clang is available, it is also used to build
perf with/without libelf.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

* [PATCH 19/54] perf pmu: Support wildcards on pmu name in dynamic pmu events

To: linux-arm-kernel
From: Agustin Vega-Frias <agustinv@codeaurora.org>
Starting on v4.12 event parsing code for dynamic pmu events already
supports prefix-based matching of multiple pmus when creating dynamic
events. E.g., in a system with the following dynamic pmus:
mypmu_0
mypmu_1
mypmu_2
mypmu_4
passing mypmu/<config>/ as an event spec will result in the creation of
the event in all of the pmus. This change expands this matching through
the use of fnmatch so glob-like expressions can be used to create events
in multiple pmus. E.g., in the system described above if a user only
wants to create the event in mypmu_0 and mypmu_1, mypmu_[01]/<config>/
can be passed.

To simplify creation of events accross multiple instances of the same
type of PMU stat supports two methods for creating multiple events from
a single event specification:
1. A prefix or glob can be used in the PMU name.
2. Aliases, which are listed immediately after the Kernel PMU events
by perf list, are used.
When the --no-merge option is passed and these events are displayed
individually the PMU name is lost and it's not possible to see which
count corresponds to which pmu:
$ perf stat -a -e l3cache/read-miss/ --no-merge ls > /dev/null
Performance counter stats for 'system wide':
67 l3cache/read-miss/
67 l3cache/read-miss/
63 l3cache/read-miss/
60 l3cache/read-miss/
0.001675706 seconds time elapsed
$ perf stat -a -e l3cache_read_miss --no-merge ls > /dev/null
Performance counter stats for 'system wide':
12 l3cache_read_miss
17 l3cache_read_miss
10 l3cache_read_miss
8 l3cache_read_miss
0.001661305 seconds time elapsed
This change adds the original pmu name to the event. For dynamic pmu
events the pmu name is restored in the event name:
$ perf stat -a -e l3cache/read-miss/ --no-merge ls > /dev/null
Performance counter stats for 'system wide':
63 l3cache_0_3/read-miss/
74 l3cache_0_1/read-miss/
64 l3cache_0_2/read-miss/
74 l3cache_0_0/read-miss/
0.001675706 seconds time elapsed
For alias events the name is added after the event name:
$ perf stat -a -e l3cache_read_miss --no-merge ls > /dev/null
Performance counter stats for 'system wide':
10 l3cache_read_miss [l3cache_0_3]
12 l3cache_read_miss [l3cache_0_1]
10 l3cache_read_miss [l3cache_0_2]
17 l3cache_read_miss [l3cache_0_0]

Auto-merge for these events was disabled when auto-merging of non-alias
events was disabled in commit 63ce844 (perf stat: Only auto-merge events
that are PMU aliases).
Non-merging of legacy events is preserved:
$ perf stat -ag -e cache-misses,cache-misses sleep 1
Performance counter stats for 'system wide':
86,323 cache-misses
86,323 cache-misses
1.002623307 seconds time elapsed
But prefix or glob matching auto-merges the events created:
$ perf stat -a -e l3cache/read-miss/ sleep 1
Performance counter stats for 'system wide':
328 l3cache/read-miss/
1.002627008 seconds time elapsed
$ perf stat -a -e l3cache_0_[01]/read-miss/ sleep 1
Performance counter stats for 'system wide':
172 l3cache/read-miss/
1.002627008 seconds time elapsed
As with events created with aliases, auto-merging can be suppressed with
the --no-merge option:
$ perf stat -a -e l3cache/read-miss/ --no-merge sleep 1
Performance counter stats for 'system wide':
67 l3cache/read-miss/
67 l3cache/read-miss/
63 l3cache/read-miss/
