make config dependency resolving was always running serial,
parallelize it for better performance.
$ time make T=x86_64-native-linuxapp-gcc config
real 0m12.633s
$ time make -j8 T=x86_64-native-linuxapp-gcc config

I have a patch that fix the same issue (configuration takes to long),
but done differently. It is more intrusive, since it rework the way
DEPDIRS are used, but it does not require to use -j.
I'm sending it as a reply to this thread.
Regards,
Olivier

Before this patch, the management of dependencies between directories
had several issues:
- the generation of .depdirs, done at configuration is slow: it can take
more than one minute on some slow targets (usually ~10s on a standard
PC).
- for instance, it is possible to expressed a dependency like:
- app/foo depends on lib/librte_foo
- and lib/librte_foo depends on app/bar
But this won't work because the directories are traversed with a
depth-first algorithm, so we have to choose between doing 'app' before
or after 'lib'.
- the script depdirs-rule.sh is too complex.
- we cannot use "make -d" for debug, because the output of make is used for
the generation of .depdirs.
This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.
After this commit, "make config" is almost immediate.

I tested the patch and the performance is very quick and seems to work very nicely. I have not looked at the other patch yet are they both compatible and could be combined or not?

No, I don't think they could be combined.
Ferruh's approach looks less risky, since it's a parallelization
of the config. My approach changes the way dependencies are processed,
and also how they are declared. I think it's faster, but more intrusive.

Olivier

I think we may hit a case of diminishing returns. On my system, the
config time goes from 12 seconds down to less than 1 second (large
amounts of parallelism). Even with limiting parallelism to just 4
make processes, the time for config drops to 3 seconds.
I don't see huge value in trying to shave off any more time than
that, given the amount of extra complexity involved.

Indeed, on a Qualcomm development board where disk I/O is quite slow:
$ git describe
v17.02-rc1-3-g61207d014fc9
$ time make config T=arm64-armv8a-linuxapp-gcc
real 1m4.308s

That is really annoying when debugging makefiles.
After applying this patch:
$ git am mk-optimize-directory-dependencies.patch
Applying: mk: optimize directory dependencies
$ rm -rf build/
$ time make config T=arm64-armv8a-linuxapp-gcc
real 0m0.111s
Almost 600 times faster than before!
I prefer this solution to the one proposed by Ferruh (which is
interesting but requires to run parallel make). Here is a test with the
other patch:
$ git am mk-parallelize-make-config.patch
Applying: mk: parallelize make config
$ rm -rf build/
$ grep -c processor /proc/cpuinfo
24
$ time make config T=arm64-armv8a-linuxapp-gcc -j24
real 0m11.253s
Here only 6 times faster than before, even when using 24 parallel
processes.

Hi Robin,
what are the differences in the patches like when doing a build rather
than just a config? If the build is minutes long because of slow IO,
is the extra 10 seconds really going to make that much of a difference?

I agree that Olivier's patch is faster. However, I think I prefer having
the library dependencies in the makefiles for the libs themselves rather
than up a level. Given that we are only looking at ~2second of a
difference here in your tests - assuming -j flag - what is the actual
build time differences? My suspicion is that after Ferruh's simpler
patch is applied, the config time becomes such a small part of the
build, that the extra benefits from Oliviers work is not worth the extra
complexity.

I agree there is no significant difference in total build time (config
included) when using -j8 (about ~15s). And I understand your concern
about the complexity of the patch in the second solution.
But the way dependencies are computed is overly complex and I feel that
parallelizing is just hiding dust under the carpet. The result after the
second solution is cleaner (to me): we get rid of an obscure shell
script and we stop piping make output to files thus restoring the
possibility to use make -d to debug problems.
And while the goal is to reduce the config time, why not go all the
way?

Without patch - 18sec
With patch -j1 - 18 sec
With patch -j2 - 9.2 sec
With patch -j4 - 4.9 sec
With patch -j8 - 2.8 sec
With patch -j16 - 1.7 sec
With patch -j32 - 1.4 sec

The low-end embedded SoCs (SoC with 2 to 4 cores) will be get benefited out
of bring this extra complexity.My take is, if it is manageable complexity then
take the most optimized one.

Hi Olivier,
It seems both have pros and cons,
Your patch pros,
- faster
- and simpler implementation.
cons,
- Need to update another Makefile in another level to update
dependencies of a library/driver.
- Root level dependencies hardcoded to a mk level makefile.
- removes depgraph target too, not sure how commonly used
Original implementation pros:
- self contained, it manages dependencies of library in same Makefile
- no hardcoded dependencies, all resolved dynamically
cons,
- relatively slower, but not too bad with -j make option.
- complex implementation
I would prefer my version, surprisingly J, but it is good to have
alternatives, and I don't have strong opinion against your patch.
Thanks,
ferruh

Ok. Point taken for the lower-core count parts.
Thomas - can at least one of these patches be merged into 17.02, since it will definitely help us developers? [If Olivier's is too big a change at this point in the cycle, can Ferruh's be taken as an intermediate fix for this release before merging Olivier's in 17.05?]

It looks to be a good option. Ferruh's patch is less risky for 17.02.

It could be interesting to explain why it was not parallelized,
and how you made it possible.
The test script should be updated as below:
--- a/devtools/test-build.sh

- make T=$2 O=$1 config
+ make -j$J T=$2 O=$1 config

These DEPDIRS are files, although DEPDIRS in other contexts are directories.
I think it should be renamed. DEPDIR_FILES?

This part is a bit complicated.

If there is no dependency (DEPDIRS-y) set and there is nothing to do
here, make prints a line like "nothing to do", since we redirect the
output to the files, that msg goes into .depdir files. To prevent that
msg, added a dummy action here.

make config dependency resolving was always running serial,
parallelize it for better performance.
$ time make T=x86_64-native-linuxapp-gcc config
real 0m12.633s
$ time make -j8 T=x86_64-native-linuxapp-gcc config
real 0m1.826s
When config creation done under a single make target, using a for loop,
make has no control on the action, and it needs to run as implemented in
the rule. But if for loop converted into multiple targets, make can
detect independent targets and run them parallel based on -j parameter.

The Ferruh's version has been merged in 17.02.
Are we still OK to take Olivier's version in 17.05?
Olivier, are you going to update/rebase it?

From: Olivier Matz @ 2017-03-17 17:13 UTC (permalink / raw)
To: dev; +Cc: thomas.monjalon, ferruh.yigit, robin.jarry, jerin.jacob, keith.wiles
Before this patch, the management of dependencies between directories
had several issues:
- the generation of .depdirs, done at configuration is slow: it can take
more than one minute on some slow targets (usually ~10s on a standard
PC without -j).
- for instance, it is possible to express a dependency like:
- app/foo depends on lib/librte_foo
- and lib/librte_foo depends on app/bar
But this won't work because the directories are traversed with a
depth-first algorithm, so we have to choose between doing 'app' before
or after 'lib'.
- the script depdirs-rule.sh is too complex.
- we cannot use "make -d" for debug, because the output of make is used for
the generation of .depdirs.
This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.
After this commit, "make config" is almost immediate.

RFC -> v1:
- rebase on top of current master
- interleave DIRS-* and DEPDIRS-* targets for more readability

-Deps Targets
-------------
-
-* depdirs
-
- This target is implicitly called by make config.
- Typically, there is no need for a user to call it,
- except if DEPDIRS-y variables have been updated in Makefiles.
- It will generate the file $(RTE_OUTPUT)/.depdirs.
-
- Example:
-
- .. code-block:: console
-
- make depdirs O=mybuild
-
-* depgraph
-
- This command generates a dot graph of dependencies.
- It can be displayed to debug circular dependency issues, or just to understand the dependencies.
-
- Example:
-
- .. code-block:: console
-
- make depgraph O=mybuild > /tmp/graph.dot && dotty /tmp/ graph.dot

Thanks, I'll check for other occurrences.

It's a typo, I'll remove it in v2.

Before this patch, the management of dependencies between directories
had several issues:
- the generation of .depdirs, done at configuration is slow: it can take
more than one minute on some slow targets (usually ~10s on a standard
PC without -j).
- for instance, it is possible to express a dependency like:
- app/foo depends on lib/librte_foo
- and lib/librte_foo depends on app/bar
But this won't work because the directories are traversed with a
depth-first algorithm, so we have to choose between doing 'app' before
or after 'lib'.
- the script depdirs-rule.sh is too complex.
- we cannot use "make -d" for debug, because the output of make is used for
the generation of .depdirs.
This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.
After this commit, "make config" is almost immediate.

v1 -> v2:
- remove invalid comments in app and test makefiles
- remove additional space in rte.subdir.mk
RFC -> v1:
- rebase on top of current master
- interleave DIRS-* and DEPDIRS-* targets for more readability

-Deps Targets
-------------
-
-* depdirs
-
- This target is implicitly called by make config.
- Typically, there is no need for a user to call it,
- except if DEPDIRS-y variables have been updated in Makefiles.
- It will generate the file $(RTE_OUTPUT)/.depdirs.
-
- Example:
-
- .. code-block:: console
-
- make depdirs O=mybuild
-
-* depgraph
-
- This command generates a dot graph of dependencies.
- It can be displayed to debug circular dependency issues, or just to understand the dependencies.
-
- Example:
-
- .. code-block:: console
-
- make depgraph O=mybuild > /tmp/graph.dot && dotty /tmp/ graph.dot

Did you notice an error? I see no error it with:
make config T=x86_64-native-linuxapp-gcc
sed -i 's,CONFIG_RTE_LIBRTE_KNI=y,# CONFIG_RTE_LIBRTE_KNI is not set,' build/.config
make -j8
I think it is not a problem, the DEPDIRS-* variable only gives an
ordering directive, which should be ok even if kni is not compiled.

Olivier

You're right, it happens because the libray list is built from DEPDIRS.
Thanks for spotting it, I'll check if there are other occurences and send
a fix. The simple way is probably to restore the ifeq(), but I'm wondering
if having: DEPDIRS-$(cond)-$(path) wouldn't be shorter in Makefiles.

In rte.lib.mk, the list of libraries passed to the link
command (LDLIBS) is generated from the DEPDIRS-xxx variables.
If a library is not compiled because it is disabled in
configuration, it should not appear in DEPDIRS-xxx.
- librte_port depends on librte_kni only if it is enabled.
- librte_table depends on librte_acl only if it is enabled.
