perf build: Add sdt feature detection

2016-07-14T02:09:09+00:00

This checks whether sys/sdt.h is available or not, which is required for
DTRACE_PROBE().

We can disable this feature by passing NO_SDT=1 when building.

This flag will be used for SDT test case and further SDT events in
perftools.

perf build: Add libbabeltrace to build-test

2016-06-28T13:54:52+00:00

'make build-test' doesn't test LIBBABELTRACE=1. It misses a building
failure caused by commit 41840d211c51 ("perf config: Move config
declarations from util/cache.h to util/config.h"), breaks bisect.

Add LIBBABELTRACE=1 to build-test.

perf build tests: Move the feature related vars to the front of the make cmdline

2016-02-04T14:27:51+00:00

So that we do less visual searching on the 'make build-test' output to
see the feature related variables:

After:

  $ make -C tools/perf build-test
  
           make_no_newt_O: cd . && make NO_NEWT=1 FEATURES_DUMP=/home/acme/git/linux/tools/perf/BUILD_TEST_FEATURE_DUMP O=/tmp/tmp.dz55IX DESTDIR=/tmp/tmp.X29xxo
              make_tags_O: cd . && make tags FEATURES_DUMP=/home/acme/git/linux/tools/perf/BUILD_TEST_FEATURE_DUMP O=/tmp/tmp.6ecLh8 DESTDIR=/tmp/tmp.6vIla578Ho

perf build tests: Elide "-f Makefile" from make invokation

2016-02-04T14:27:50+00:00

Since this is the name that 'make' will look for if no explicit -f file
is passed.

This in turn makes the output of 'build-test' more compact:

Before:

  $ perf stat make -C tools/perf build-test
  
  cd . && make FEATURE_DUMP_COPY=/home/acme/git/linux/tools/perf/BUILD_TEST_FEATURE_DUMP feature-dump
          make_no_libaudit_O: cd . && make -f Makefile  O=/tmp/tmp.tHIa0Kkk2Y DESTDIR=/tmp/tmp.foK7rckkVi NO_LIBAUDIT=1 FEATURES_DUMP=/home/acme/git/linux/tools/perf/BUILD_TEST_FEATURE_DUMP
  

After:

  $ perf stat make -C tools/perf build-test
  
          make_no_libaudit_O: cd . && make  O=/tmp/tmp.tHIa0Kkk2Y DESTDIR=/tmp/tmp.foK7rckkVi NO_LIBAUDIT=1 FEATURES_DUMP=/home/acme/git/linux/tools/perf/BUILD_TEST_FEATURE_DUMP

perf build: Align the names of the build tests:

2016-01-29T20:51:04+00:00

  $ make -C tools/perf build-test
  make[1]: Entering directory `/home/acme/git/linux/tools/perf'
                 make_pure_O: cd . && make -f Makefile  O=/tmp/tmp.mPx0Cmik3f DESTDIR=/tmp/tmp.U0SUmVbtJm
            make_clean_all_O: cd . && make -f Makefile  O=/tmp/tmp.Yl5UzhTU7T DESTDIR=/tmp/tmp.fop1E4jdER clean all
                make_debug_O: cd . && make -f Makefile  O=/tmp/tmp.pMn2ozBoXC DESTDIR=/tmp/tmp.azxhDp5sEp DEBUG=1
           make_no_libperl_O: cd . && make -f Makefile  O=/tmp/tmp.qJPiINMtA7 DESTDIR=/tmp/tmp.KNMrLeGDxZ NO_LIBPERL=1
  

More needs to be done to make it more compact, i.e. elide the '-f Makefile',
remove that 'cd . &&', move the DESTDIR= and O= to the end, as they don't
convey that much information besides the fact that they are being set to some
random directory just for this build, move the meat, i.e. the meaningful
feature disabling bits to the start, etc.

perf build: Use feature dump file for build-test

2016-01-29T17:47:52+00:00

To prevent the feature check tests to run repeately, one time per
'tests/make' target/test, this patch utilizes the previously introduced
'feature-dump' make target and FEATURES_DUMP variable, making sure that
the feature checkers run only once when doing build-test for normal test
cases.

However, since standard users doesn't reuse features dump result, we'd
better give an option to check their behaviors. The above feature
should be used to make build-test faster only. Only utilize it for
build-test.

perf build: Pass O option to kernel makefile in build-test

2016-01-15T19:32:00+00:00

Kernel makefile only follows an 'O' option passed from command line
explicitely. In build-test with 'O' option set, kernel makefile
contaminate kernel source directory. Build test also fail if we don't
create output directory manually.

K_O_OPT is added and passed to kernel makefile if 'O' is passed
to build-test.

perf build: Test correct path of perf in build-test

2016-01-15T19:31:59+00:00

If an 'O' is passed to 'make build-test', many 'test -x' and 'test -f'
will fail because perf resides in a different directory. Fix this by
computing PERF_OUT according to 'O' and test correct output files.
For make_kernelsrc and make_kernelsrc_tools, set KBUILD_OUTPUT_DIR
instead because the path is different from others ($(O)/perf vs
 $(O)/tools/perf).

perf build: Pass O option to Makefile.perf in build-test

2016-01-15T19:31:59+00:00

Unlike tools/perf/Makefile, tools/perf/Makefile.perf obey 'O' option
when it is passed through cmdline only, due to code in
tools/scripts/Makefile.include:

 ifneq ($(O),)
 ifeq ($(origin O), command line)
 	...
 	ABSOLUTE_O := $(shell cd $(O) ; pwd)
 	OUTPUT := $(ABSOLUTE_O)/$(if $(subdir),$(subdir)/)
 endif
 endif

This patch passes 'O' to Makefile.perf through cmdline explicitly
to make it follow O variable during build-test.

'make clean' should have identical 'O' option with 'make'. If not,
config-clean may error.
