From: Jiri Olsa Date: Fri, 20 Feb 2015 22:16:58 +0000 (+0100) Subject: perf tools: Add feature check for libbabeltrace X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=53d0a57343949b2af9b27229db534b98e5a0c4d0;p=linux-beck.git perf tools: Add feature check for libbabeltrace 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 ] ... DWARF post unwind library: libunwind NOTE The installation of the [1] to to used by above make: $ git clone git://git.efficios.com/babeltrace.git $ cd babeltrace $ vim README $ ./bootstrap $ ./configure --prefix=/opt/libbabeltrace $ make prefix=/opt/libbabeltrace $ sudo make install prefix=/opt/libbabeltrace Please make sure that the /opt/libbabeltrace/lib directory is in your LD_LIBRARY_PATH: $ export LD_LIBRARY_PATH=/opt/libbabeltrace/lib [1] babeltrace - http://www.efficios.com/babeltrace [2] Common Trace Format - http://www.efficios.com/ctf Signed-off-by: Jiri Olsa Acked-by: Namhyung Kim Reviewed-by: David Ahern Cc: Frederic Weisbecker Cc: Jeremie Galarneau Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Sebastian Andrzej Siewior Cc: Tom Zanussi Cc: Wang Nan Link: http://lkml.kernel.org/r/1424470628-5969-2-git-send-email-jolsa@kernel.org Signed-off-by: Sebastian Andrzej Siewior [ Added missing babeltrace build instructions ] Signed-off-by: Arnaldo Carvalho de Melo --- diff --git a/tools/perf/Makefile.perf b/tools/perf/Makefile.perf index efc5158738f4..ec4c063ed9f3 100644 --- a/tools/perf/Makefile.perf +++ b/tools/perf/Makefile.perf @@ -68,7 +68,9 @@ include config/utilities.mak # for reading the x32 mode 32-bit compatibility VDSO in 64-bit mode # # Define NO_ZLIB if you do not want to support compressed kernel modules - +# +# Define NO_LIBBABELTRACE if you do not want libbabeltrace support +# for CTF data format. ifeq ($(srctree),) srctree := $(patsubst %/,%,$(dir $(shell pwd))) diff --git a/tools/perf/config/Makefile b/tools/perf/config/Makefile index b97a7b903a23..6f129b0a9c64 100644 --- a/tools/perf/config/Makefile +++ b/tools/perf/config/Makefile @@ -96,6 +96,17 @@ ifndef NO_LIBELF FEATURE_CHECK_LDFLAGS-libdw-dwarf-unwind := $(LIBDW_LDFLAGS) -ldw endif +ifndef NO_LIBBABELTRACE + # for linking with debug library, run like: + # make DEBUG=1 LIBBABELTRACE_DIR=/opt/libbabeltrace/ + ifdef LIBBABELTRACE_DIR + LIBBABELTRACE_CFLAGS := -I$(LIBBABELTRACE_DIR)/include + LIBBABELTRACE_LDFLAGS := -L$(LIBBABELTRACE_DIR)/lib + endif + FEATURE_CHECK_CFLAGS-libbabeltrace := $(LIBBABELTRACE_CFLAGS) + FEATURE_CHECK_LDFLAGS-libbabeltrace := $(LIBBABELTRACE_LDFLAGS) -lbabeltrace-ctf +endif + # include ARCH specific config -include $(src-perf)/arch/$(ARCH)/Makefile @@ -216,6 +227,7 @@ CORE_FEATURE_TESTS = \ stackprotector-all \ timerfd \ libdw-dwarf-unwind \ + libbabeltrace \ zlib LIB_FEATURE_TESTS = \ @@ -231,6 +243,7 @@ LIB_FEATURE_TESTS = \ libslang \ libunwind \ libdw-dwarf-unwind \ + libbabeltrace \ zlib VF_FEATURE_TESTS = \ @@ -692,6 +705,17 @@ else NO_PERF_READ_VDSOX32 := 1 endif +ifndef NO_LIBBABELTRACE + ifeq ($(feature-libbabeltrace), 0) + msg := $(warning No libbabeltrace found, disables 'perf data' CTF format support, please install libbabeltrace-devel/libbabeltrace-ctf-dev);
