A dynamic entry is created for each tracepoint event. When it sets up
the sort key, it checks with existing keys using ->equal() callback.
But it missed to set the ->equal for dynamic entries. The following
segfault was due to the missing ->equal() callback.

Normally the hist entry's srcline and/or srcfile is set during sorting.
However sometime it's possible to a hist entry's srcline is not set yet
after the sorting. This is because the entry is so unique and other
sort keys already make it distinct. Then the srcline/file sort didn't
have a chance to be called during the sorting. In that case it has NULL
srcline/srcfile field and shows nothing.
Before:
$ perf report -s comm,sym,srcline

The srcline, srcfile and trace sort keys can have long entries. With
commit 89fee7094323 ("perf hists: Do column alignment on the format
iterator"), it now aligns output with hist_entry__snprintf_alignment().
So each (possibly long) sort entries don't need to do it themselves.

It missed to update column length of the 'trace' sort key in the
hists__calc_col_len() so it might truncate the output. It calculated
the column length in the ->cmp() callback originally but it doesn't
guarantee it's called always.

The dynamic entry is created for each field in a tracepoint event.
Since they have no fixed hpp format index, it should skip when
perf_hpp__reset_width() is called.
This caused following assertion failure..
$ perf record -e sched:sched_switch -a sleep 1
$ perf report -s comm,next_pid --stdio
perf: ui/hist.c:651: perf_hpp__reset_width:
Assertion `!(fmt->idx >= PERF_HPP__MAX_INDEX)' failed.

From: Wang Nan <wangnan0@huawei.com>
bpf__config_obj() is introduced as a core API to config BPF object after
loading. One configuration option of maps is introduced. After this
patch BPF object can accept assignments like:
map:my_map.value=1234
(map.my_map.value looks pretty. However, there's a small but hard to fix
problem related to flex's greedy matching. Please see [1]. Choose ':'
to avoid it in a simpler way.)
This patch is more complex than the work it does because the
consideration of extension. In designing BPF map configuration, the
following things should be considered:
1. Array indices selection: perf should allow user setting different
value for different slots in an array, with syntax like:
map:my_map.value[0,3...6]=1234;
2. A map should be set by different config terms, each for a part
of it. For example, set each slot to the pid of a thread;
3. Type of value: integer is not the only valid value type. A perf
counter can also be put into a map after commit 35578d798400
("bpf: Implement function bpf_perf_event_read() that get the
selected hardware PMU counter")
4. For a hash table, it should be possible to use a string or other
value as a key;
5. It is possible that map configuration is unable to be setup
during parsing. A perf counter is an example.
Therefore, this patch does the following:
1. Instead of updating map element during parsing, this patch stores
map config options in 'struct bpf_map_priv'. Following patches
will apply those configs at an appropriate time;
2. Link map operations in a list so a map can have multiple config
terms attached, so different parts can be configured separately;
3. Make 'struct bpf_map_priv' extensible so that the following patches
can add new types of keys and operations;
4. Use bpf_obj_config__map_funcs array to support more map config options.
Since the patch changing the event parser to parse BPF object config is
relative large, I've put it in another commit. Code in this patch can be
tested after applying the next patch.

This patch adds the final step for BPF map configuration. A new syntax
is appended into parser so user can config BPF objects through '/' '/'
enclosed config terms.
After this patch, following syntax is available:
# perf record -e ./test_bpf_map_1.c/map:channel.value=10/ ...
It would takes effect after appling following commits.
Test result:
# cat ./test_bpf_map_1.c

From: Wang Nan <wangnan0@huawei.com>
bpf__apply_obj_config() is introduced as the core API to apply object
config options to all BPF objects. This patch also does the real work
for setting values for BPF_MAP_TYPE_PERF_ARRAY maps by inserting value
stored in map's private field into the BPF map.
This patch is required because we are not always able to set all BPF
config during parsing. Further patch will set events created by perf to
BPF_MAP_TYPE_PERF_EVENT_ARRAY maps, which is not exist until
perf_evsel__open().
bpf_map_foreach_key() is introduced to iterate over each key needs to be
configured. This function would be extended to support more map types
and different key settings.
In perf record, before start recording, call bpf__apply_config() to turn
on all BPF config options.

A new syntax is added to the parser so that the user can access
predefined perf events in BPF objects.
After this patch, BPF programs for perf are finally able to utilize
bpf_perf_event_read() introduced in commit 35578d798400 ("bpf: Implement
function bpf_perf_event_read() that get the selected hardware PMU
counter").

From: Wang Nan <wangnan0@huawei.com>
This patch introduces basic facilities to support config different slots
in a BPF map one by one.
array.nr_ranges and array.ranges are introduced into 'struct
parse_events_term', where ranges is an array of indices range (start,
length) which will be configured by this config term. nr_ranges is the
size of the array. The array is passed to 'struct bpf_map_priv'. To
indicate the new type of configuration, BPF_MAP_KEY_RANGES is added as a
new key type. bpf_map_config_foreach_key() is extended to iterate over
those indices instead of all possible keys.
Code in this commit will be enabled by following commit which enables
the indices syntax for array configuration.

From: Wang Nan <wangnan0@huawei.com>
This patch introduces a new syntax to perf event parser:
# perf record -e './test_bpf_map_3.c/map:channel.value[0,1,2,3...5]=101/' usleep 2
By utilizing the basic facilities in bpf-loader.c which allow setting
different slots in a BPF map separately, the newly introduced syntax
allows perf to control specific elements in a BPF map.
Test result:
# cat ./test_bpf_map_3.c
/************************ BEGIN **************************/
#include <uapi/linux/bpf.h>
#define SEC(NAME) __attribute__((section(NAME), used))

unsigned int max_entries;
};

(void *)BPF_FUNC_map_lookup_elem;
static int (*trace_printk)(const char *fmt, int fmt_size, ...) =
(void *)BPF_FUNC_trace_printk;
struct bpf_map_def SEC("maps") channel = {
.type = BPF_MAP_TYPE_ARRAY,
.key_size = sizeof(int),
.value_size = sizeof(unsigned char),
.max_entries = 100,
};

int func(void *ctx, int err, long nsec)
{
char fmt[] = "%ld\n";
long usec = nsec * 0x10624dd3 >> 38; // nsec / 1000
int key = (int)usec;
unsigned char *pval = map_lookup_elem(&channel, &key);
if (!pval)
return 0;
trace_printk(fmt, sizeof(fmt), (unsigned char)*pval);
return 0;
}

\___ Index too large
Hint: Valid config terms:
map:[<arraymap>].value<indices>=[value]
map:[<eventmap>].event<indices>=[event]
where <indices> is something like [0,3...5] or [all]
(add -v to see detail)
Run 'perf list' for a list of valid events
Usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]
-e, --event <event> event selector. use 'perf list' to list available events

From: Wang Nan <wangnan0@huawei.com>
Users can pass options to tracepoints defined in the BPF script. For
example:
# perf record -e ./test.c/no-inherit/ bash
# dd if=/dev/zero of=/dev/null count=10000
# exit
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.022 MB perf.data (139 samples) ]
(no-inherit works, only the sys_read issued by bash are captured, at
least 10000 sys_read issued by dd are skipped.)
test.c:
#define SEC(NAME) __attribute__((section(NAME), used))
SEC("func=sys_read")
int bpf_func__sys_read(void *ctx)
{
return 1;
}
char _license[] SEC("license") = "GPL";
int _version SEC("version") = LINUX_VERSION_CODE;
no-inherit is applied to the kprobe event defined in test.c.

Commit a43eec304259 ("bpf: introduce bpf_perf_event_output() helper")
adds a helper to enable a BPF program to output data to a perf ring
buffer through a new type of perf event, PERF_COUNT_SW_BPF_OUTPUT. This
patch enables perf to create events of that type. Now a perf user can
use the following cmdline to receive output data from BPF programs:
# perf record -a -e bpf-output/no-inherit,name=evt/ \
-e ./test_bpf_output.c/map:channel.event=evt/ ls /
# perf script
perf 1560 [004] 347747.086295: evt: ffffffff811fd201 sys_write ...
perf 1560 [004] 347747.086300: evt: ffffffff811fd201 sys_write ...
perf 1560 [004] 347747.086315: evt: ffffffff811fd201 sys_write ...

perf tools: Fix static linking with libunwind (2017-08-22 13:24:55 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Expression parser enhancements for metrics (Andi Kleen)
- Fix buffer overflow while freeing events in 'perf stat' (Andi Kleen)
- Fix static linking with elfutils's libdf and with libunwind
in Debian/Ubuntu (Konstantin Khlebnikov)
- Tighten detection of BPF events, avoiding matching some other PMU
events such as 'cpu/uops_executed.core,cmask=1/' as a .c source
file that ended up being considered a BPF event (Andi Kleen)
- Add Skylake server uncore JSON vendor events (Andi Kleen)
- Add support for printing new mem_info encodings, including
'perf test' checks (Andi Kleen)
- Really install manpages via 'make install-man' (Konstantin Khlebnikov)
- Fix documentation for perf_event_paranoid and perf_event_mlock_kb
sysctls (Konstantin Khlebnikov)

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.

Hi Ingo,
Please consider pulling,

Test results at the end of this message, as usual.
The following changes since commit ee438ec8f33c5af0d4a4ffb935c5b9272e8c2680:
Merge tag 'perf-core-for-mingo-4.14-20170725' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2017-07-26 19:07:30 +0200)

perf data: Add doc when no conversion support compiled (2017-07-28 16:30:45 -0300)
----------------------------------------------------------------
perf/core improvements and fixes for 4.14:
New features:
- Add PERF_SAMPLE_CALLCHAIN and PERF_RECORD_MMAP[2] to 'perf data' CTF
conversion, allowing CTF trace visualization tools to show callchains
and to resolve symbols (Geneviève Bastien)
Improvements:
- Use group read for event groups in 'perf stat', reducing overhead when
groups are defined in the event specification, i.e. when using {} to
enclose a list of events, asking them to be read at the same time,
e.g.: "perf stat -e '{cycles,instructions}'" (Jiri Olsa)
Fixes:
- Do not overwrite perf_sample->weight in 'perf annotate' when
processing samples, use whatever came from the kernel when
perf_event_attr.sample_type has PERF_SAMPLE_WEIGHT set or just handle
its default value, 0, when that is not set and "weight" is one of the
sort orders chosen (Arnaldo Carvalho de Melo)
- 'perf annotate --show-total-period' fixes:
- TUI should show period, not nr_samples
- Set appropriate column width for period/percent
- Fix the column header to show "Period" when when that is what
is being asked for
(Taeung Song, Arnaldo Carvalho de Melo)
- Use default sort if evlist is empty, fixing pipe mode (David Carrillo-Cisneros)

Hi Ingo,
Please consider pulling,
- Arnaldo
Test results at the end of this message, as usual.
The following changes since commit f2029b1e47b607619d1dd2cb0bbb77f64ec6b7c2:
perf/x86/intel: Add Kaby Lake support (2017-02-11 21:28:23 +0100)

for you to fetch changes up to a734fb5d60067a73dd7099a58756847c07f9cd68:
samples/bpf: Reset global variables (2017-02-13 17:22:53 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
New feature:
- Introduce the 'delta-abs' 'perf diff' compute method, that orders the
histogram entries by the absolute value of the percentage delta for a
function in two perf.data files, i.e. the functions that changed the
most (increase or decrease in samples) comes first (Namhyung Kim)
User visible:
- Improve message about tweaking the kernel.perf_event_paranoid setting,
telling how to make the change permanent by editing /etc/sysctl.conf
(Ingo Molnar)
Infrastructure:
- Introduce linux/compiler-gcc.h as a counterpart to the kernel's,
initially containing the definition of __fallthrough, more to
come (__maybe_unused, etc) (Arnaldo Carvalho de Melo)
- Fixes for problems uncovered by building tools/perf with clang, such
as always true tests of arrays against NULL and variables that sometimes
were used without being initialized (Arnaldo Carvalho de Melo, Steven Rostedt)
- Before loading a new ELF, clear global variables set by the
samples/bpf loader (Mickaël Salaün)
- Ignore already processed ELF sections in the samples/bpf
loader (Mickaël Salaün)
- Fix compile error in the scripting code with some perl5
versions (Wang YanQing)

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.
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.

perf tools: Add missing object file to the python binding linkage list (2016-10-26 19:08:43 -0200)
----------------------------------------------------------------
perf/core improvements and fixes:
New features:
- Support matching by topic in 'perf list' (Andi Kleen)
User visible:
- Apply cpu color only when there was activity in 'perf sched map' (Namhyung Kim)
- Always show the task's COMM in 'perf sched map -v' (Namhyung Kim)
- Fix hierarchy column counts in the perf hist browser (top, report), avoiding
showing nothing after pressing the RIGHT key a number of times (Namhyung Kim)
Infrastructure:
- Support cascading options in libsubcmd and use it to share common options in
'perf sched' subcommands (Namhyung Kim)
- Avoid worker cacheline bouncing in 'perf bench futex' (Davidlohr Bueso)
- Sanitize numeric parameters in 'perf bench futex' (Davidlohr Bueso)
- Update copies of kernel files (Arnaldo Carvalho de Melo)
- Fix scripting (perl, python) setup to avoid leaks (Arnaldo Carvalho de Melo)
- Add missing object file to the python binding linkage list (Arnaldo Carvalho de Melo)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

perf tests: Add is_printable_array test (2016-07-18 19:50:35 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Properly report when a function wildcard produces no matches in 'perf probe'
(Masami Hiramatsu)
- Balance opening and reading events in 'perf stat', which could cause
it to get stuck trying to close invalid file descriptors (Mark Rutland)
Infrastructure:
- Copy more headers from the kernel, this time for headers that
were just including the contents of its kernel counterparts, should
help resolving the problems with linux-next, where some uapi related
patches seem to be breaking tools/object/ build.
Some more combing will be done, but at least it is possible to build
perf out of tree, via a detached tarball (make help | grep perf)
without including kernel files in its MANIFEST (Arnaldo Carvalho de Melo)
- Fix smatch found errors that were not causing problems, but are
mistakes nonetheless (Dan Carpenter)
- Fix string vs byte array resolving in the python script code (Jiri Olsa)

Hm, so I pulled it (commit 1765d9b26f84), but with an old perf.data I'm getting
this crash:
triton:~/tip/tools/perf> perf report
perf: Segmentation fault
-------- backtrace --------

I also re-tested 1765d9b26f84 and it still crashes.
Bisected it to:

Running on Ubuntu, 1 socket box, 12 CPUs.
I went back to perf/core 8f3e5684d3fb and it doesn't crash anymore - so I unpulled
your tree for now. (Will send you the perf.data privately.)
Thanks,

Thanks! I have already removed that problematic changeset and resigned
the 'perf-core-for-mingo-2' tag, same contents modulo that cset.

Ingo, please do not pull this 'perf-core-for-mingo-2' tag, there were
some misunderstandings about the acks for "Move sw clock metrics
printout to stat-shadow" and Jiri and Andi are working that out.
I'll remove those patches and get a new perf-core-for-mingo-2
tag in place, before continuing today's batch, which possibly will be
available as 'perf-core-for-mingo-3'
What is in 'perf-core-for-mingo" should be Ok.

perf trace: Handle missing HUGEPAGE defines (2013-08-30 15:43:28 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
. Tidy up sample parsing validation, from Adrian Hunter.
. Make events stream always parsable by adding a new sample_type bit:
PERF_SAMPLE_IDENTIFIER, that when requested will be always aat a fixed
position in all PERF_RECORD_ records, from Adrian Hunter.
. Add a sample parsing test, from Adrian Hunter.
. Add option to 'perf trace' to analyze events in a file versus live,
so that one can do:
[root@zoo ~]# perf record -a -e raw_syscalls:* sleep 1
[ perf record: Woken up 0 times to write data ]
[ perf record: Captured and wrote 25.150 MB perf.data (~1098836 samples) ]

perf report: Fix build with NO_NEWT=1 (2013-02-28 16:51:01 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
. Honor parallel jobs, fix from Borislav Petkov
. Introduce tools/lib/lk library, initially with just debugfs handling routines
shared with tools/vm, more to come, from Borislav Petkov
. Fix handling of -C (cpus) in perf record, from Jiri Olsa
. Add perf_event_attr entries in 'perf test' to check -C handling in 'record'
and 'stat', from Jiri Olsa.
. Check if -DFORTIFY_SOURCE=2 is allowed, fix from Marcin Slusarz.
. Fix build with NO_NEWT=1, from Michael Ellerman.
