2015-02-12perf build: Add arch x86 objects buildingJiri Olsa
Move the x86 arch objects building under build framework to be included in the libperf build object. Adding also arch/$(ARCH)/Build files for the rest of the archs. The reason for this is that in arch/Build we now do: +libperf-y += $(ARCH)/ which would make the build to fail on other architectures, because the build framework requires 'Build' file in nested directories and this patch adds it only for x86.

2015-02-11tools build: Add new build supportJiri Olsa
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>

Do not rely on dso__data_read_offset() will always call dso__data_fd() internally. With multi-thread support, accessing a fd will be protected by a lock and it'll cause a huge contention. It can be avoided since we can skip reading from file if there's a data in the dso cache.

The current dso cache permits to keep dso->data.fd is open under a half of open file limit.

2015-01-29perf evsel: Set attr.task bit for a tracking eventNamhyung Kim
The perf_event_attr.task bit is to track task (fork and exit) events but it missed to be set by perf_evsel__config(). While it was not a problem in practice since setting other bits (comm/mmap) ended up being in same result, it'd be good to set it explicitly anyway. The attr->task is to track task related events (fork/exit) only but other meta events like comm and mmap[2] also needs the task events. So setting attr->comm and/or attr->mmap causes the kernel emits the task events anyway. So the attr->task is only meaningful when other bits are off but I'd like to set it for completeness.
