The return type is not defined, so it defaults to int, however, the
function is not returning anything, so this is clearly not correct. Make
it a void function.

Currently, when injecting build ids, if there is AUX data then 'perf
inject' hits all DSOs because it is not known which DSOs the trace data
would hit.
That needs to be done for JIT injection also, and in fact there is no
reason to distinguish what kind of injection is being done. That is,
any time there is AUX data and the HEADER_BUID_ID feature flag is set,
and the AUX data is not being processed, then hit all DSOs. This patch
does that.

Very sorry, but I just noticed that this and patch 5 (perf jit: Move clockid
validation) have the wrong email address for the "From" and "Signed-off-by".
It should be adrian.hunter@intel.com. Please consider changing it or
dropping these patches for now.

Ok, I've changed these two patches and have applied the whole series from email.

In preparation for moving clockid validation into jit_process().
Previously a return value of zero meant the processing had been done and
non-zero meant either the processing was not done (i.e. not the jitdump
file mmap event) or an error occurred.
Change it so that zero means the processing was not done, one means the
processing was done and successful, and negative values are an error.

Commit b9511cd761fa ("perf/x86: Fix time_shift in perf_event_mmap_page")
altered the time conversion algorithms documented in the perf_event.h
header file, to use 64-bit shifts. That was done to make the code more
future-proof (i.e. some time in the future a 32-bit shift could be
allowed). Reflect those changes in perf tools.

The level field is to distinguish levels in the hierarchy mode.
Currently each column (perf_hpp_fmt) has a different level.

I'm surprised this remained undocumented since at least 2011. And it is
actually a very useful switch, as Steve and I came to realize recently.
Add the text from
2cba3ffb9a9d ("perf stat: Add -d -d and -d -d -d options to show more CPU events")
which added the incrementing aspect to -d.

Btw., something I noticed: it would be really nice if 'perf stat -h -d' printed
the most detailed documentation available for the option. Right now it prints:
triton:~/tip/tools/perf> perf stat -h -d
Usage: perf stat [<options>] [<command>]
-d, --detailed detailed run - start a lot of events
The only way to get to the most detailed documentation is the not very obvious
path of:
perf help stat
and then searching for '-d'.
Ideally there should only be a single place to document options - but I guess
unifying the in-code option descriptions and more verbose description in the man
pages is very non-trivial ...
Thanks,
Ingo

The perf_hpp__setup_hists_formats() is to build hists-specific output
formats (and sort keys). Currently it's only used in order to build the
output format in a hierarchy with same sort keys, but it could be used
with different sort keys in non-hierarchy mode later.

From: Namhyung Kim <namhyung@kernel.org>
Now each hists has its own hpp lists in hierarchy. So instead of having
a pointer to a single perf_hpp_fmt in a hist entry, make it point the
hpp_list for its level. This will be used to support multiple sort keys
in a single hierarchy level.

From: Namhyung Kim <namhyung@kernel.org>
This implements having multiple sort keys in a single hierarchy level.
Originally only single sort key is supported for each level, but now
using the group syntax with '{ }', it can set more than one sort key in
one level. Note that now it needs to quote in order to prevent shell
interpretation.
For example:
$ perf report --hierarchy -s '{comm,dso},sym'
...
# Overhead Command / Shared Object / Symbol
# .............. ..........................................
#
48.67% swapper [kernel.vmlinux]
34.42% [k] intel_idle
1.30% [k] __tick_nohz_idle_enter
1.03% [k] cpuidle_reflect
8.87% firefox libpthread-2.22.so
6.60% [.] __GI___libc_recvmsg
1.18% [.] pthread_cond_signal@@GLIBC_2.3.2
1.09% [.] 0x000000000000ff4b
6.11% Xorg libc-2.22.so
5.27% [.] __memcpy_sse2_unaligned
In the above example, the command name and the shared object name are
shown on the same line but the symbol name is on the different line.
Since the first two are grouped by '{}', they are in the same level.

When multiple sort keys are used in a single hierarchy, it should indent
using number of hierarchy levels instead of number of sort keys.

Now hpp formats are linked using perf_hpp_list_node when hierarchy is
enabled. Use this info to print entries with multiple sort keys in a
single hierarchy properly.
For example, the below example shows using 4 sort keys with 2 levels.
$ perf report --hierarchy -s '{prev_pid,prev_comm},{next_pid,next_comm}' \
--percent-limit 1 -i perf.data.sched
...
# Overhead prev_pid+prev_comm / next_pid+next_comm

Now hpp formats are linked using perf_hpp_list_node when hierarchy is
enabled. Like in stdio, use this info to print entries with multiple
sort keys in a single hierarchy properly.

hi,
perf build failed for me on s390x because of jitdump feature.
Attached patch tries to enable the build only on supported archs.
I haven't followed this feature too much, so I might have missed
something.. anyway it builds on s390x now ;-) I took the list of
archs from util/genelf.h
thanks,
jirka

Make jitdump being built only on architectures
defined in util/genelf.h file.

Hi Jiri,
This may be related to this cset, still not in tip/perf/core:
commit 46dad054a19297af65c417c97cb920aa5bdf7e8c
Author: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Mon Mar 7 18:48:45 2016 -0300
perf jitdump: DWARF is also needed
Can you check if without this one perf builds on s390?
This patch is to make it build on ubuntu without libdw, i.e. it requires
both libdw and libelf, the way I fixed it may not be the best and
probably we need to fold these two patches before sending to Ingo, since
your patch essentially rewrites my previous patch :-)
Can you please check that?

well there's following line in util/genelf.h:
#else
#error "unsupported architecture"
#endif
which makes the build fail on unssuported arch,
even without your patch:
CC util/jitdump.o
In file included from util/jitdump.c:23:
util/genelf.h:41:2: error: #error "unsupported architecture"
util/genelf.h:44:5: error: "GEN_ELF_CLASS" is not defined
mv: cannot stat `util/.jitdump.o.tmp': No such file or directory
make[3]: *** [util/jitdump.o] Error 1
