But with the current upstream, metric events names are not printed properly In power9 platform: command:# ./perf stat --metric-only -M translation -C 0 -I 1000 sleep 2 1.000208486 2.000368863 2.001400558 Similarly in skylake platform: command:./perf stat --metric-only -M Power -I 1000 1.000579994 2.002189493 With current upstream version, issue is with event name comparison logic in find_evsel_group(). Current logic is to compare events belonging to a metric group to the events in perf_evlist. Since the break statement is missing in the loop used for comparison between metric group and perf_evlist events, the loop continues to execute even after getting a pattern match, and end up in discarding the matches. Incase of single metric event belongs to metric group, its working fine, because in case of single event once it compare all events it reaches to end of perf_evlist. Example for single metric event in power9 platform: command:# ./perf stat --metric-only -M branches_per_inst -I 1000 sleep 1 1.000094653 0.2 1.001337059 0.0 This patch fixes the issue by making sure once we found all events belongs to that metric event matched in find_evsel_group(), we successfully break from that loop by adding corresponding condition. With this patch: In power9 platform: command:# ./perf stat --metric-only -M translation -C 0 -I 1000 sleep 2 result:# time derat_4k_miss_rate_percent derat_4k_miss_ratio derat_miss_ratio derat_64k_miss_rate_percent derat_64k_miss_ratio dslb_miss_rate_percent islb_miss_rate_percent 1.000135672 0.0 0.3 1.0 0.0 0.2 0.0 0.0 2.000380617 0.0 0.0 0.0 0.0 0.0 0.0 0.0 command:# ./perf stat --metric-only -M Power -I 1000 Similarly in skylake platform: result:# time Turbo_Utilization C3_Core_Residency C6_Core_Residency C7_Core_Residency C2_Pkg_Residency C3_Pkg_Residency C6_Pkg_Residency C7_Pkg_Residency 1.000563580 0.3 0.0 2.6 44.2 21.9 0.0 0.0 0.0 2.002235027 0.4 0.0 2.7 43.0 20.7 0.0 0.0 0.0 Committer testing: Before: [root@seventh ~]# perf stat --metric-only -M Power -I 1000 # time 1.000383223 2.001168182 3.001968545 4.002741200 5.003442022 ^C 5.777687244 [root@seventh ~]# After the patch: [root@seventh ~]# perf stat --metric-only -M Power -I 1000 # time Turbo_Utilization C3_Core_Residency C6_Core_Residency C7_Core_Residency C2_Pkg_Residency C3_Pkg_Residency C6_Pkg_Residency C7_Pkg_Residency 1.000406577 0.4 0.1 1.4 97.0 0.0 0.0 0.0 0.0 2.001481572 0.3 0.0 0.6 97.9 0.0 0.0 0.0 0.0 3.002332585 0.2 0.0 1.0 97.5 0.0 0.0 0.0 0.0 4.003196624 0.2 0.0 0.3 98.6 0.0 0.0 0.0 0.0 5.004063851 0.3 0.0 0.7 97.7 0.0 0.0 0.0 0.0 ^C 5.471260276 0.2 0.0 0.5 49.3 0.0 0.0 0.0 0.0 [root@seventh ~]# [root@seventh ~]# dmesg | grep -i skylake [ 0.187807] Performance Events: PEBS fmt3+, Skylake events, 32-deep LBR, full-width counters, Intel PMU driver.

In case the number of entries hadn't been reduced (was NPROC*4), the warning was printed. However, some systems might have unusual cache topology, such as the following two-processor KVM guest: cpu level shared_cpu_list size 0 1 0 32K 0 1 0 64K 0 2 0 512K 0 3 0 8192K 1 1 1 32K 1 1 1 64K 1 2 1 512K 1 3 1 8192K This KVM guest has 8 (NPROC*4) unique cache entries, which used to make perf printing the message, although there actually aren't "way too many cpu caches". v2: Removing unused argument. v3: Unifying the way we obtain number of cpus. v4: Removed '& UINT_MAX' construct which is redundant.

perf record: Combine some auxtrace initialization into a single function (2018-03-06 12:03:39 -0300)
----------------------------------------------------------------
perf/urgent fixes:
- Be more robust when drawing arrows in the annotation TUI, avoiding a
segfault when jump instructions have as a target addresses in functions
other that the one currently being annotated. The full fix will come in
the following days, when jumping to other functions will work as call
instructions (Arnaldo Carvalho de Melo)
- Prevent auxtrace_queues__process_index() from queuing AUX area data for
decoding when the --no-itrace option has been used (Adrian Hunter)
- Sync copy of kvm UAPI headers and x86's cpufeatures.h (Arnaldo Carvalho de Melo)
- Fix 'perf stat' CVS output format for non-supported counters (Ilya Pronin)
- Fix crash in 'perf record|perf report' pipe mode (Jiri Olsa)
- Fix annoying 'perf top' overwrite fallback message on older kernels (Kan Liang)
- Fix the usage on the 'perf kallsyms' man page (Sangwon Hong)

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.

Hi Ingo,
So here it is the fixes in perf-core-for-mingo-4.14-20170912, as
requested, plus one last minute fix from Milian Wolff that helps with
using perf as an AppImage[1].

perf stat: Wait for the correct child (2017-09-12 12:49:13 -0300)
----------------------------------------------------------------
perf/urgent fixes:
- 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)

Test results:
The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.
Where clang is available, it is also used to build perf with/without libelf.
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.
The 'perf test' also runs shell scripts exercising the tools, checking
if they affect the system in certain ways, like setting up kprobes and
uprobes, request callchains for well known programs and check that they
are the expected ones, see if 'perf trace' beautifies system call
arguments correctly, etc.
Additionally, a new set of tests, script based, runs the tools in a live system,
setting probes in place that then gets used by 'perf trace', with its output
compared against expected results.
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.
