perf tools: Fix cache event name generation (2012-09-06 15:01:08 -0300)
----------------------------------------------------------------
perf/core improvements and fixes
. Fix hardware cache event name generation, fix from Jiri Olsa
. Add round trip test for sw, hw and cache event names, catching the
problem Jiri fixed, after Jiri's patch, the test passes successfully.
. Clean target should do clean for lib/traceevent too, fix from David Ahern
. Check the right variable for allocation failure, fix from Namhyung Kim
. Set up evsel->tp_format regardless of evsel->name being set already,
fix from Namhyung Kim

It's built as part of perf, so it should be cleaned too.

Current perf_evlist__set_tracepoint_names is a misnomer because it finds
and sets correspoding event_format in addition to the name. So skipping
it when a event has set name already caused a trouble.
Rename it and set name only a event doesn't have one.

It basically traverses the hardware and software event name arrays
creating an evlist with all events, then it uses perf_evsel__name to
check that the name is the expected one.
With it I noticed this problem:
[root@sandy ~]# perf test 10
10: roundtrip evsel->name check:invalid or unsupported event: 'CPU-migrations'
Run 'perf list' for a list of valid events
FAILED!
Changed it to "cpu-migrations" in the software event arrays and it
worked.
This is to catch problems like the one reported by Joel Uckelman in
http://permalink.gmane.org/gmane.linux.kernel.perf.user/1016
Hardware cache events will be checked in the following patch.

Fixing this by properly adjusting the string index.

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,
I pulled tip/perf/urgent to pick up fixes, please consider
pulling, I've been away for a while, so I'll be harvesting outstanding
patches in the next few days, as well as trying and reviewing more
complex patchkits,

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.

Nice changes!
Btw., wouldn't it be even better to allow partial matches? Not allowing
'sched:sched_switc' is unnecessarily pedantic IMHO.
For example 'perf list' allows partial matches as well. As long as the resulting
event is unique, we should allow partial matches. If it's not unique, we should
print the first 3 matching entries or so.
There's a real UI advantage as well: I could abbreviate the command line with:
-e sched_sw
instead of always being forced to type out the full tracepoint name.
(Programmatic tracepoint usage and portable scripts should naturally always spell
out the full event, to make sure new tracepoints don't cause overlaps - but ad-hoc
usage can do abbreviations just fine.)

Hi Ingo,
Please consider pulling,
- Arnaldo
The following changes since commit 9059b284caecb628fac826c2c5cc8ee85708eec1:
Merge tag 'perf-core-for-mingo-2' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2015-09-15 08:50:59 +0200)

perf tools: Introduce regs_query_register_offset() for x86 (2015-09-15 09:48:33 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Enhance the error reporting of tracepoint event parsing, e.g.:
$ oldperf record -e sched:sched_switc usleep 1
event syntax error: 'sched:sched_switc'
\___ unknown tracepoint
Run 'perf list' for a list of valid events
Now we get the much nicer:
$ perf record -e sched:sched_switc ls
event syntax error: 'sched:sched_switc'
\___ can't access trace events
Error: No permissions to read /sys/kernel/debug/tracing/events/sched/sched_switc
Hint: Try 'sudo mount -o remount,mode=755 /sys/kernel/debug'
And after we have those mount point permissions fixed:
$ perf record -e sched:sched_switc ls
event syntax error: 'sched:sched_switc'
\___ unknown tracepoint
Error: File /sys/kernel/debug/tracing/events/sched/sched_switc not found.
Hint: Perhaps this kernel misses some CONFIG_ setting to enable this feature?.
Now its just a matter of using what git uses to suggest alternatives when we
make a typo, i.e. that it is just an 'h' missing :-)
I.e. basically now the event parsing routing uses the strerror_open()
routines introduced by and used in 'perf trace' work. (Jiri Olsa)
Infrastructure:
- Export init/exit_probe_symbol_maps() from 'perf probe' for use in eBPF
(Namhyung Kim)
- Free perf_probe_event in cleanup_perf_probe_events() (Namhyung Kim)
- regs_query_register_offset() infrastructure + implementation for x86.
First user will be the perf/eBPF code (Wang Nan)

Nice!! :-)
Btw., it would be nice if the status line carried information about whether
collection is 'frozen' or running, at a glance. A hint might also suggest how to
unfreeze the session - in case someone pressed Ctrl-Z to suspend the perf top
session ...
Also, there's now a GUI inconsistency with perf report: which will now exit on
Ctrl-Z. It should probably print a warning in the status line instead, that
freezing/unfreezing only works in 'perf top'.

Hi Ingo,
Please consider pulling, this is on top of perf-core-for-mingo, that is
still outstanding,
Thanks!

perf top: Allow disabling/enabling events dynamicly (2015-06-17 16:50:52 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Allow disabling/enabling events dynamicly in 'perf top':
a 'perf top' session can instantly become a 'perf report'
one, i.e. going from dynamic analysis to a static one,
returning to a dynamic one is possible, to toogle the
modes, just press CTRL+z. (Arnaldo Carvalho de Melo)
- Greatly speed up 'perf probe --list' by caching debuginfo
(Masami Hiramatsu)
- Fix 'perf trace' race condition at the end of started
workloads (Sukadev Bhattiprolu)
- Fix a problem when opening old perf.data with different
byte order (Wang Nan)
Infrastructure:
- Ignore .config-detected in .gitignore (Wang Nan)
- Move libtraceevent dynamic list to separated LDFLAGS
variable (Wang Nan)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
----------------------------------------------------------------
Arnaldo Carvalho de Melo (2):
perf evlist: Add toggle_enable() method
perf top: Allow disabling/enabling events dynamicly
Masami Hiramatsu (2):
perf probe: Show usage even if the last event is skipped
perf probe: Speed up perf probe --list by caching debuginfo
Sukadev Bhattiprolu (1):
perf trace: Fix race condition at the end of started workloads
Wang Nan (3):
perf tools: Ignore .config-detected in .gitignore
perf tools: Fix a problem when opening old perf.data with different byte order
perf tools: Move libtraceevent dynamic list to separated LDFLAGS variable
