* tools build: Allow duplicate objects in the object listJiri Olsa2015-08-263-1/+3
| | | | | | | | | | | | | | | | | | It's sometimes useful to specify the object affiliation to multiple config options like: libperf-$(CONFIG_X86) += tsc.o libperf-$(CONFIG_AUXTRACE) += tsc.o while the object itself is linked only once. Adding the support for this and ignoring duplicate objects in the object list.

* perf tools: Add Intel PT instruction decoderAdrian Hunter2015-08-171-0/+2
| | | | | | | | | | | | | | | Add support for decoding instructions for Intel Processor Trace. The kernel x86 instruction decoder is copied for this. This essentially provides intel_pt_get_insn() which takes a binary buffer, uses the kernel's x86 instruction decoder to get details of the instruction and then categorizes it for consumption by an Intel PT decoder.

* perf tools: Support static linking with libdwAndi Kleen2015-08-131-1/+6
| | | | | | | | | | | | | | | The Fedora 22 version of libdw requires a couple of extra libraries to link. With a dynamic link the dependencies are pulled in automatically, but this doesn't work for static linking. Add the needed libraries explicitely to the feature probe and the Makefile. v2: Explicitly check for static linking and only add the dependencies when -static is set. This is to avoid regressions on Arnaldo's system.

* bpf tools: Introduce 'bpf' library and add bpf feature checkWang Nan2015-08-072-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the first patch of libbpf. The goal of libbpf is to create a standard way for accessing eBPF object files. This patch creates 'Makefile' and 'Build' for it, allows 'make' to build libbpf.a and libbpf.so, 'make install' to put them into proper directories. Most part of Makefile is borrowed from traceevent. Before building, it checks the existence of libelf in Makefile, and deny to build if not found. Instead of throwing an error if libelf not found, the error raises in a phony target "elfdep". This design is to ensure 'make clean' still workable even if libelf is not found. Because libbpf requires 'kern_version' field set for 'union bpf_attr' (bpfdep" is used for that dependency), Kernel BPF API is also checked by intruducing a new feature check 'bpf' into tools/build/feature, which checks the existence and version of linux/bpf.h. When building libbpf, it searches that file from include/uapi/linux in kernel source tree (controlled by FEATURE_CHECK_CFLAGS-bpf). Since it searches kernel source tree it reside, installing of newest kernel headers is not required, except we are trying to port these files to an old kernel. To avoid checking that file when perf building, the newly introduced 'bpf' feature check doesn't added into FEATURE_TESTS and FEATURE_DISPLAY by default in tools/build/Makefile.feature, but added into libbpf's specific.

* tools build: Add new build supportJiri Olsa2015-02-1115-0/+441
Adding new build framework into 'tools/build' to be used by tools. There's no change for actual building at this point, it comes in the next patches. The idea and more details are explained in the 'tools/build/Documentation/Build.txt' file. I adopted everything from the kernel build system, with some changes to allow for multiple binaries build definitions. While the kernel's build output is single image (forget modules) we need to be able to build several binaries/libraries. The basic idea is that sser provides 'Build' files with objects definitions like: perf-y += a.o perf-y += b.o libperf-y += c.o libperf-y += d.o and the build framework outputs files: perf-in.o # a.o, b.o compiled in libperf-in.o # c.o, d.o compiled in Signed-off-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com> Tested-by: Will Deacon <will.deacon@arm.com> Cc: Alexis Berlemont <alexis.berlemont@gmail.com> Cc: Borislav Petkov <bp@alien8.de> Cc: Corey Ashford <cjashfor@linux.vnet.ibm.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-fbj22h4av0otlxupwcmrxgpa@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
