1.8.3.1
Start the split-out of the feature check code by adding a list of features to be
tested, and rules to process that list by building its matching feature-check
file in config/feature-checks/test-<feature>.c.
Add 'hello' as the initial feature.
This structure will allow us to build split-out feature checks in parallel and
thus speed up feature detection dramatically.
No change in functionality: no feature check is used by the build rules yet.

1.8.3.1
Implement automatic parallel builds when building in tools/perf:
$ time make
# [ perf build: Doing 'make -j12' parallel build. ]
Auto-detecting system features:
...
real 0m9.265s
user 0m59.888s
sys 0m6.082s
On GNU make achieving this is not particularly easy, it requires a separate
makefile, which then invokes the main Makefile.
( Note: this patch adds Makefile.parallel to show the concept - the two
makefiles will be flipped in the next patch to avoid having to specify -f
to get parallelism in the default build. )

David Ahern reported that when passing in LDFLAGS=-static then
the feature checks still succeed - causing build failures down
the line because the static libraries are missing.
Solve this by passing through LDFLAGS to the feature-check
Makefile.

are out in the open make them prettier.

If someone specifies a single target, mixed with O=, the following way:
hubble:~/tip/tools/perf> make O=/tmp/perf util/stat.o
BUILD: Doing 'make -j8' parallel build
gcc -Wbad-function-cast -Wdeclaration-after-statement -Wformat-security -Wformat-y2k [...]
The build might even fail, if a target depends on other targets:
hubble:~/tip/tools/perf> make O=/tmp/perf perf.o
...
perf.c: In function ‘handle_options’:
perf.c:155:21: error: ‘PERF_HTML_PATH’ undeclared (first use in this function)
The correct way to invoke such targets is:
hubble:~/tip/tools/perf> make O=/tmp/perf /tmp/perf/perf.o
BUILD: Doing 'make -j8' parallel build
GEN /tmp/perf/common-cmds.h
CC /tmp/perf/perf.o
But that's unnecessary typing and it's also easy to mistakenly build into the
source directory.
To fix this remove the generic suffix rules and add redirection to $(OUTPUT)
for the most popular .o targets.

Jiri reported that 'make .o' stopped working:
> [jolsa@krava perf]$ make -f Makefile perf.o
> cc -c -o perf.o perf.c
> In file included from builtin.h:4:0,
> from perf.c:9:
> util/util.h:74:24: fatal error: lk/debugfs.h: No such file or directory
> compilation terminated.
> make: *** [perf.o] Error 1
This is due to GNU make having built-in rules for popular targets such
as *.o. Clear them out so that all targets as passed through to Makefile.perf.

Prepare to include them into test-all.c directly, by making sure
that they build cleanly and without warnings.
Also make sure they make a certain amount of sense and don't crash
when executed.

1.8.3.1
The detection of certain rarely detected features can be delayed
to when they are actually needed.
So speed up the common case of auto-detection by pre-building only
a core set of features and populating only their feature-flags.
[ Features not listed in CORE_FEATURES need to built explicitly
via the feature_check() function. ]
(Also order the feature names alphabetically, while at it.)

Change the print-out of auto-detected features by making sure that
repeat invocations of 'make' when all features are successfully
detected do not produce the (rather lengthy) autodetection printout.
( When one or more features are missing then we still print out the
feature detection table, to make sure people are aware of the
resulting limitations. )

To make it more apparent that there is not change in functionality we introduced
Makefile.parallel separately and now flip it with the main Makefile, which
moves into Makefile.perf.
The renames are:
Makefile.parallel => Makefile
Makefile => Makefile.perf

1.8.3.1
Linus reported the following perf build system bug:
'Another annoyance during that make was that "make install" seems to
want to re-make the thing I just built. That's absolutely horrible, [...]'
The thing that got re-built were 'only' the (numerous) feature checks,
not the whole project - but still it was mighty annoying as the feature
checks took 9+ seconds even on reasonably fast boxes.
Even with the autodep patches where feature detection is much faster
it wastes resources, wastes screen real estate and confuses users if
we execute feature detection twice.
There were two sources for these unnecessary re-builds of the feature
checks:
- Unnecessary nested invocations of $(MAKE), apparently to be able
to do conditional compilation dependent on documentation tools
presence. Use straight dependencies instead, with no nesting.
- A direct invocation of $(MAKE) to rebuild the PERF-VERSION-FILE.
This is apparently done to be able to include it into the
Makefile:
-include $(OUTPUT)PERF-VERSION-FILE
but that's entirely pointless for two reasons: 1) the version file
gets regenerated by the initial build pass anyway, 2) including it
is futile, given its contents:
#define PERF_VERSION "3.12.rc3.g8510c7"
'make' will interpret that as a comment line...
So just remove this part of the doc-generation logic.
With these things fixed a 'make install' now rebuilds only what is needed.
A repeated 'make install' on an already built tree is super fast now,
it finishes in under 0.3 seconds:
#
# After the patch:
#
$ time make install
...
real 0m0.280s
user 0m0.162s
sys 0m0.054s
Prior all the autodep changes and prior this fix, a repeat 'make install'
took 24.1 seconds (!) on the same system:
#
# Before the patches:
#
$ time make install
...
real 0m24.109s
user 0m21.171s
sys 0m2.449s
Which almost entirely was caused by fixable build system fat.
We are now literally ~86 times faster.
A fresh rebuild and install now takes just 11.4 seconds:
#
# After the patch:
#
$ make clean
$ time make -j16 install
...
real 0m11.457s
user 1m43.411s
sys 0m7.610s
Without the patches it took 27.8 seconds:
#
# Before the patches:
#
$ make clean
$ time make -j16 install
...
real 0m27.801s
user 1m59.242s
sys 0m9.749s
So even in the complete rebuild case we are now ~2.5 times faster.

1.8.3.1
libtraceevent.a and liblk.a rules have always-missed dependencies,
which causes python.so to be relinked at every build attempt - even
if none of the affected code changes.
This slows down re-builds unnecessarily, by adding more than a second
to the build time:
comet:~/tip/tools/perf> time make
...
SUBDIR /fast/mingo/tip/tools/lib/lk/
make[1]: `liblk.a' is up to date.
SUBDIR /fast/mingo/tip/tools/lib/traceevent/
LINK perf
GEN python/perf.so
real 0m1.701s
user 0m1.338s
sys 0m0.301s
Add the (trivial) dependencies to not force a re-link.
This speeds up an empty re-build enormously:
comet:~/tip/tools/perf> time make
...
real 0m0.207s
user 0m0.134s
sys 0m0.028s
[ This adds some coupling between the build dependencies of
libtraceevent and liblk - but until those stay relatively
simple this should not be an issue. ]

Concatenate all feature checks into test-all.c.
This can be built and checked faster than all the individual tests.
If test-all fails then we still check all the individual features, so
this is a pure speedup, it should have no effects on functionality.

1.8.3.1
util/PERF-VERSION-GEN is currently executed on every build attempt,
and this script can take a lot of time on trees that are at a
significant git-distance from Linus's tree:
$ time util/PERF-VERSION-GEN
real 0m4.343s
user 0m4.176s
sys 0m0.140s
It also takes a lot of time if the Git repository is network attached, etc.,
because the commands it uses:
TAG=$(git describe --abbrev=0 --match "v[0-9].[0-9]*" 2>/dev/null )
has to count commits from the nearest tag and thus has to access (and
decompress) every git commit blob on the relevant version path.
Even on Linus's tree it takes 0.28 seconds on a fast box to count all the
commits and get the git version string:
$ time util/PERF-VERSION-GEN
real 0m0.279s
user 0m0.247s
sys 0m0.025s
But the version string only has to be regenerated if the git repository's
head commit changes. So add a dependency of ../../.git/HEAD and touch
the file every time it's regenerated, so that Make's build rules can
pick it up and cache the result:
make: `PERF-VERSION-FILE' is up to date.
real 0m0.184s
user 0m0.117s
sys 0m0.026s

1.8.3.1
The strlcpy() feature check slows every build unnecessarily - so make it
a __weak function so it does not have to be auto-detected.
If the libc (or any other library) has an strlcpy() implementation it will
be used - otherwise our fallback is active.

1.8.3.1
Use GCC's -MD feature to generate a dependency file for each feature test .c file,
and include that .d file in the config/feature-checks/Makefile.
This allows us to do two things:
- speed up feature tests
- detect removal or changes in build dependencies - including system libraries/headers

nproc is probably ubiquitous enough to use now
(available since coreutils 8.1 (end of 2009))
As well as being more concise, it will take
account of offline CPUs etc.

/proc/cpuinfo takes account of offline CPUs as well:
# grep -c ^processor /proc/cpuinfo 2>/dev/null
16
# echo 0 > /sys/devices/system/cpu/cpu11/online
# grep -c ^processor /proc/cpuinfo 2>/dev/null
15
# echo 1 > /sys/devices/system/cpu/cpu11/online
# grep -c ^processor /proc/cpuinfo 2>/dev/null
16
But nproc is indeed a better choice:
1)
It is scheduler syscall based and will thus will work in limited
environments as well, for example when /proc is not mounted.
2)
It will also properly detect affinity-limited environments:
# taskset 1 nproc
1
3)
It is also faster than grepping /proc/cpuinfo:
# perf stat --null --repeat 100 nproc >/dev/null
Performance counter stats for 'nproc' (100 runs):
0.000652928 seconds time elapsed ( +- 0.53% )
versus:
# perf stat --null --repeat 100 grep -c ^processor /proc/cpuinfo >/dev/null
Performance counter stats for 'grep -c ^processor /proc/cpuinfo' (100 runs):
0.001037034 seconds time elapsed ( +- 0.32% )
so with 0.652 msecs versus 1.037 msecs it's about 60% faster than grep.
Thanks,
Ingo

You are dropping the above so add-on libunwind support will break.

So as far as I can see, all the feature checking goes twice - once in
$(shell make ...) and another in $(foreach test,...). They look like
doing exactly same thing. And the final Makefile in this series still
has it twice. Is it intentional or did I miss something?
Thanks,
Namhyung

The flag being checked should be -"W"stack-protector instead of
-"f"stack-protector. And the gcc manpage says that -Wstack-protector is
only active when -fstack-protector is active. So the end result should
look like
$(BUILD) -Werror -fstack-protector -Wstack-protector
Thanks,

I'm not sure this test is necessary at all.
The gcc manpage says this warning is enabled by -Wall, and we add -Wall
to CFLAGS before doing feature checks. So all gcc versions that support
-Wvolatile-register-var enables it by default without this check and
older gcc versions will always fail the feature check.

As Ulrich Drepper reported, it seems that this hunk is duplicate.

Duplicate PACKAGE definitions. It seems only one is needed and it
should look like a normal C string like -DPACKAGE='"perf"' IMHO.

Just a nitpick. The manpage says the on_exit() requires <stdlib.h>
header rather than <stdio.h> and _BSD_SOURCE or _SVID_SOURCE defined.
So I think we can define _GNU_SOURCE before the header file or pass it
through make command line - it'd probably be better for synthesized
test-all.c checking.

Also missed -Wstack-protector. And duplicate -Werror.
Anyway, it'd be great to generate this flags as well as source file
automatically.

Hmm... it'd be great if there's a way to detect -jN option and convert

I got this:
$ cd tools/perf
$ make
... (succeeded)
$ make O=~/build/perf perf.o
make: `perf.o' is up to date.
$ rm ~/build/perf/perf.o
$ make O=~/build/perf/ perf.o
make: `perf.o' is up to date.

It also doesn't care about other directories - arch/, scripts/ and ui/ -
and their subdirectories. So even on clean build it'll failed to build
these files with O=dir.
$ make clean
$ make O=~/build/perf ui/stdio/hist.o
BUILD: Doing 'make -j12' parallel build
make[1]: *** No rule to make target `ui/stdio/hist.o'. Stop.
make: *** [ui/stdio/hist.o] Error 2

I looked hard but couldn't find any solution for that, GNU Make hides it.
It seems to be possible on other Make platforms - so I suspect that will
have to be a feature request to the GNU Make folks ...

Yes, this is a limitation: it will only do the redirection if the source
repository is clean.
I don't see a simple solution for that, do you?

Correct - only tried to cover the most common cases. Could add all the
other directories if this is something people would like to use on a
regular basis.
I also attempted to do a generic rule that can see into subdirectories,
using secondary expansion rules, but my first few attempts failed at
producing anything usable ;-) My Make fu still needs working on.
Suggestions welcome!

What I think this patch does is to _remove_ the whitespace damage that was
present in the previous feature-tests.mak method.
This hunk changes spaces to tabs.
Agreed?

This was inherited from the original feature-tests.mak:
define SOURCE_ON_EXIT
#include <stdio.h>
int main(void)
{
return on_exit(NULL, NULL);
}
endef
So it appears to work in practice, but yes, I agree that this could be
cleaned up.
Thanks,

Namhyung Kim reported these duplicate DPACKAGE definitions:
test-libbfd:
$(BUILD) -DPACKAGE='perf' -DPACKAGE=perf -lbfd -ldl
Fix all affected places and use Namhyung's suggestion that the
definition should look like a normal C string: -DPACKAGE='"perf"'.

This was pre-existing, but indeed it's an unnecessary duplication. I'll

Ulrich Drepper and Namhyung Kim reported that the libelf logic in

Remove the duplication, and also remove the now unused FLAGS_LIBELF

So, I think this testcase only wanted to check whether GCC knows the
option or not, right?
Nevertheless I agree that we could add -Wstack-protector to be on the safe
side, I'll send a patch for that.
Thanks,

Yes - and this is a performance trick.
The first run is to build them all in parallel:
$(shell $(MAKE) OUTPUT=$(OUTPUT_FEATURES) LDFLAGS=$(LDFLAGS) -i -j -C config/feature-checks $(CORE_FEATURE_TESTS) >/dev/null 2>&1)
Note how we build in parallel (-j), ignore errors (-i) and suppress all
output.
This is very fast even if all testcases are rebuilt, but we cannot
possibly recover which feature test failed.
So we run it once more, this time serially, and recover the test results.
The vast majority of testcases will pass, and the repeat build will do, in
essence:
comet:~/tip/tools/perf/config/feature-checks> perf stat --null --repeat 10 make test-libelf >/dev/null
Performance counter stats for 'make test-libelf' (10 runs):
0.014682647 seconds time elapsed ( +- 0.14% )
so it's just 14 msecs to recover each testcase result.
In theory we could optimize this further, by generating an actual test
success/failure file via the initial parallel make attempt, and recovering
those flags via the serial loop. That should be even faster.
Thanks,

Well, the source file would mean some extra construction overhead during
detection - but generating the flags ought to be possible, by putting the
test-all entry last and generating a rolling ALL_FLAGS variable via the
rules above it.
Would you like to write such a patch?
Thanks,

Okay, got it. Thanks for the explanation! :)

Well, I think it's already fast enough. ;)

I don't think it's a common usecase.

Well, my make fu (make skill?) is also poor. ;)
I'll try to do something about it though.
