perf build: Move feature checks code under tools/build

2015-03-21T17:53:35Z

Moving feature checks code under tools/build directory. Changing also $feature_dir to point to new feature directory location and perf Makefiles to include Makefile.feature from new location.

perf build: Move features build output under features directory

2015-03-18T17:53:38Z

Following commit introduced features build dump: 443a70541c56 perf tools: Output feature detection's gcc output to a file Moving them into to have code more compact and renaming build dump files. For each feature 'test-X' new file 'test-X.make.output' is created and contains the build out. It's created in the same directory as the feature itself.

perf build: Disable default check for libbabeltrace

2015-03-18T17:43:36Z

Remove libbabeltrace check from default features set, because the requested version is not released yet in most distributions. We'll enable later. Calling libbabeltrace check manually via feature_check before $(feature-libbabeltrace) is used.

perf build: Fix libbabeltrace detection

2015-03-12T15:39:56Z

Following patch added -Werror for feature builds: b49f1a4be701 perf tools: Improve feature test debuggability and exposed a problem in the libbabeltrace feature build, because it was including wrong header and gcc couldn't find the used symbol definition. Adding proper header and keeping the old one as it is needed also (libbabeltrace quirk).

perf tools: Initialize cpu set in pthread_attr_setaffinity_np feature test

Feature tests are compiled but not executed, however it might avoid a future uninitialized variable warning, so initialize the cpu set. Reported-by: Ingo Molnar Signed-off-by: Adrian Hunter Cc: H.

perf tools: Improve feature test debuggability

2015-03-02T15:17:44Z

Certain feature tests fail with link errors: triton:~/tip/tools/perf/config/feature-checks> make test-libbabeltrace.bin gcc -MD -o test-libbabeltrace.bin test-libbabeltrace.c # -lbabeltrace provided by /tmp/cc6dRSqd.o: In function `main': test-libbabeltrace.c:(.text+0xf): undefined reference to `bt_ctf_stream_class_get_packet_context_type' although they should already fail with a build error due to lack of a proper prototype for the function. Due to this I first tried to find which library was missing - while it was the whole feature that was missing from the .h file already. To solve this, propagate -Wall -Werror to all testcases and remove them from testcase Makefile rules that used them explicitly. A missing feature now outputs: triton:~/tip/tools/perf/config/feature-checks> make test-libbabeltrace.bin gcc -MD -Wall -Werror -o test-libbabeltrace.bin test-libbabeltrace.c # -lbabeltrace provided by test-libbabeltrace.c: In function ‘main’: test-libbabeltrace.c:6:2: error: implicit declaration of function ‘bt_ctf_stream_class_get_packet_context_type’ [-Werror=implicit-function-declaration] Signed-off-by: Ingo Molnar Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/20150228091627.GF31887@gmail.com Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Add feature check for libbabeltrace

2015-02-25T15:42:24Z

Adding feature check for babeltrace library [1], which will be used for perf data file CTF [2] conversion in following patches. The babeltrace library is now automatically detected as standard feature. It's possible to specify LIBBABELTRACE_DIR make variable to specify location of installed libbabeltrace, like: $ make LIBBABELTRACE_DIR=/opt/libbabeltrace/ BUILD: Doing 'make -j4' parallel build Auto-detecting system features: ... dwarf: [ on ] ... glibc: [ on ] ... gtk2: [ on ] ... libaudit: [ on ] ... libbfd: [ on ] ... libelf: [ on ] ... libnuma: [ on ] ... libperl: [ on ] ... libpython: [ on ] ... libslang: [ on ] ... libunwind: [ on ] ... libbabeltrace: [ on ] ... libdw-dwarf-unwind: [ on ] ... zlib: [ on ] ...
